This Flourless Chocolate Orange Cake is a stunning, 7 ingredient dessert made entirely in your blender.
You know the feeling you get when you meet someone and instantly connect? It might be the way they talk, a certain word they use, or the books stacked on their shelves, but something clicks, and you know this is one of your people. The other day, I went to a friend’s house and noticed her movie collection included all the seasons of 24, the Anne of Green Gables trilogy, and all the seasons of Gilmore Girls. I immediately knew she was a kindred spirit.
The crazy thing is, I often have this feeling about people I’ve never even met. Or (nerd alert), people who don’t even exist. If Anne of Green Gables were real, we would for sure be BFFs or, as she would say, bosom friends. I feel the same way about Belle from Beauty and the Beast and Jess from New Girl. I just feel like we’d get each other, ya know?
I’d never really been into cooking shows until I saw one of Nigella Lawson’s shows. That woman gets me. I simply love her approach to cooking and baking. It’s elegant without being fussy, which really describes her as a person as well.
This is a woman who licks the spatula, eats leftovers straight out of the fridge, and doesn’t bother if a few lemon seeds happen to slip into her cake. She doesn’t spend hours obsessing over the way her food looks, yet she makes some of the most irresistible looking dishes I’ve ever seen. When something turns out a bit lopsided or cracked, she doesn’t fret, she simply says “that’s how they’ll know it’s homemade!” She’s my kind of baker.
This Flourless Chocolate Orange Cake comes from the great Nigella, and it’s the epitome of what her baking is like. It’s incredibly simple-only 7 ingredients!-and it all comes together in a blender. That’s right. There’s no creaming, no mixing wet ingredients in one bowl and dry in the next. It’s all done with just a few pulses on your blender. See why I love her so much?
So, what is flourless chocolate orange cake made of?
This chocolate orange cake begins by boiling oranges for 2 hours until they’re soft and tender. Don’t worry, no hands on work is required during this time. All you do is toss them in a pot, cover, and let them go. This happens to be a great way to make your house smell amazing.
Once the oranges are soft they get pureed, whole, with all of the other ingredients, which include eggs, cocoa, cinnamon, and hazelnut flour or finely ground hazelnuts. I used Bob’s Red Mill Hazelnut Meal/Flour, but you can also grind up your own hazelnuts or sub finely ground almonds/almond meal.
After the mixture is pureed into a batter, it’s poured into a cake pan, baked, and VOILA. Gorgeous chocolatey orange cake is served!
I’ll be honest, I was REALLY skeptical about this cake. I wasn’t sure if I would like the combination of chocolate and orange, and I was certain that grinding up whole oranges (peel and all!) would result in a bitter cake.
But Nigella was dead on with this one. This cake is dense and chocolatey with a punchy orange flavor. It’s not bitter but rather earthy; the citrus tones are mellowed but still quite pronounced.
Is Flourless Chocolate Cake Gluten Free?
Not all flourless cakes are gluten free, but this one is! It also happens to be dairy free, butter free, and oil free, which makes it great for a variety of dietary restrictions.
One word of warning: this cake does not have the texture you would expect from a traditional flour cake. It’s not fluffy or light, but instead substantial and rich with a very moist, nutty crumb.
What Frosting Goes with Flourless Chocolate Cake?
There are a million different ways you could dress this cake up. Ganache would be a lovely, decadent addition (my friend has a wonderful microwave chocolate ganache), and a whipped cream cheese frosting would also work well (the one I use with this Easy Strawberry Cake is my personal favorite).
But if you want to stay true to the spirit of Nigella and go the classy, no frills route, a light dusting of powdered sugar is all you need.
This cake is classic, elegant, and fitting for a fancy dinner party or just a quiet evening at home. Feel free to add a few curled orange peels to the top, or simply leave it bare. This cake is sure to turn heads, whether you accessorize it or not.
If you love this cake but need a quick gluten free chocolate cake fix, try this Paleo Chocolate Mug Cake for one! You may also enjoy my rich and chewy Almond Joy Cookies.
This Flourless Chocolate Orange Cake is made in the blender and produces a moist, nutty cake with understated elegance. The hazelnut meal can be substituted with almond meal.

Chocolate Orange Cake

I love the chocolate and orange combo! It looks so rich and delicious!
Oh yes, Nigella knows how to make one seriously good cake (I’ve made her Guinness chocolate cake before and OH MY LANS). Can’t wait to try this one! Pinned!
That sounds ridiculously awesome. I’m sure if Nigella made it, it’s amazing.
Oh my god – Anne of Green Gables. I used to watch that series as a kid. I loved it! Anyway, I can’t believe this cake is made in the blender. How awesome. It looks a.ma.zing.
I know, right? Blender cake for the win! And I’m glad there are some fellow Anne with an e appreciators out there!
Too funny! I loved Anne of Green Gables and Belle is my favorite princess! I totally get it!! This cake is nothing short of extraordinary! Looks absolutely stunning!
Thanks Tanya! I’m so glad there are some other Anne with an e fans out there! 🙂
Looks absolutely gorgeous, Courtney – loved reading this post!
I’ve always loved chocolate and orange together. This looks amazing!
How decadent and chocolate and orange is so good together!
Chocolate and orange are one of my favorite flavor combinations. This cake looks so good!
Thanks Marly! I really want to find more ways to incorporate the two flavors.
I love Nigella too! She’s amazing! Love this cake as well! mmm who are my kindred spirits? I’m not sure haha. I do hear a lot of myself when I read your blog though! lol
Totally! I remember we had a total twin moment around our birthdays last year.
Is it wrong that I want to have that powdered sugar sprinkled directly into my mouth? Ah-mazing girl.
Not at all! I know the feeling.
I have never seen Nigella. Isn’t that odd. Not sure if it’s Canadian programming or I just never see her on anything. Silly. But now that I’ve seen this I want to worship her. And you for making this.
She’s not on much any more but I think she has a show on about once a week on the cooking channel. I DVR all of them, of course. 🙂
Chocolate and orange is one of my favorite flavor combinations. I also love flourless chocolate cake- rich and decadent!
Chocolate and orange cake…YES PLEASE! 🙂
Chocolate and orange are meant to be together! In fact, they say that if someone’s craving chocolate and is trying to lose weight, they should eat an orange because there’s some chemical in the orange that mimics chocolate. Anyhow, I adore Nigella too. I don’t see her much anymore but I still think she’s awesome. This cake is proof. It looks amazing.
No way! I’ve never heard that about oranges before, but that’s pretty awesome if it works!
Love how decadent this cake looks! Perfectly rich and delicious!
Thanks friend!
Wow! And now I’m craving this cake! Amazing.
What a fabulous flavor combination! And a flourless chocolate cake I haven’t made!!! I’m going to give this one a shot soon. Thanks, Courtney!
I’m sure you will make an absolutely divine chocolate orange cake Liz!
Dude, I love this. Cake in the blender??? Sign me up. PS was the hazelnut flour uber expensive? and where did you get it?
Ehhhh…it’s kind of expensive. I actually was lucky enough to have this batch sent to me. But I can find it at the Kroger near me as well!
I’m so curious about this cake! Especially the whole orange in the blender thing but it looks amazing and Nigella really does know what she’s talking about. p.s. Out of all the Disney princesses I always connected with Belle probably because I was and still am a book nerd.
I was really skeptical, but it totally worked! And I’m a book nerd too. That’s totally why Belle is my bosom buddy. 🙂
The fact that this cake is made in the blender is amazing! I totally have to give this a try!
I can’t wait to try this! All I have is a 10″ springform pan. Could I use a regular 8″ pan or use the 10″ springform and adjust the time?
I think it’d be fine to use a regular 8 inch pan, you just might have to serve it directly from the pan. The 10 inch would also work, though it may be a little thin. Let me know if you try it!
I have the Anne trilogy too, as well as all of the books. I’m a hard core Anne fan for life. Another reason why you ‘n I are bosom friends 🙂 This cake is out of control, Courtney. It’s absolutely gorgeous and sinful and decadent. I’ve heard of this technique of boiling a citrus and then using the entire fruit in a cake. I really really want to try it myself, especially if I end up with something as beautiful as your cake. And these photos – you’ve outdone yourself! They’re spectacular! I love dark moody atmospheric photos like these. Perfection.
Aren’t they the best? Anne with an e is my favorite! Thanks for the comment on the photos. I’m trying to experiment more with the dark and moody. Sometimes I fail miserably, but I liked the way these turned out for the most part. Definitely let me know if you try the boiling citrus technique on something else. I’d love to try doing a lemon cake now! Plus, it really is a great air freshener. 🙂
I have no doubt we would be buddies. I loved Gilmore Girls when it was on air. Jess from New Girl is my idol, and Nigella wakes up at night to raid the refrigerator (my kind of gal). This cake is stunning, and your photos are absolutely lovely. Pinning!
Oh yes Jennie! We would definitely be friends. I seriously feel like Jess would be the best to hang out with. Too bad she’s not real. :/
Chocolate and orange is such a classic combo – love how gorgeous this turned out!
Yes, I’ve totally had that kind of connection before! It always amazes me. Omg, I had not idea anyone outside my family heard of Anne of Green Gables…my sisters and I love that series…so cool.
I love this cake, especially the photo of powdered sugar being sprinkled on top! Orange and chocolate is delicious. 🙂
Tina from http://www.tinaschic.com
You’re definitely not the only ones. I love Anne of Green Gables. My hubby and I even went to Prince Edward Island for our honeymoon! It was beautiful!
“Orange and Chocolate” Interesting Combination. I would love to try out your recipe for my customers. I own an Italian Restaurant in Glen Waverley Melbourne called Fedeles and I am sure everyone here will love this.
I saw this cake on Foodgawker…it is a head-turner! I love flourless chocolate cake, and I think the orange sounds like a great way to change it up. Pinning!
Thanks Marcie! I was suprised how wonderful the flavors went together!
So delicious, this cake looks almost too good to eat, almost…
Thank you! Somehow I always find the will to eat it. 🙂
Please clarify – boil the oranges peeled or unpeeled? Please reply to my email?
Hi Jan, you boil the oranges whole with the peel on. Hope you enjoy it!
Thank you!
So to clarify … once boiled and sliced you blend the oranges with the peels? Only remove the seeds and keep peel on?
Thanks
That’s right! I know it sounds crazy, but it works!
Made this today for my birthday. Simply amazing. Don’t get frustrated if the blender gives trouble…just mix and do your best hand mixing some if necessary. I made a ganache to top it
I’m so glad you liked it! The ganache sounds wonderful. Thanks for coming back to let me know…it makes my day!
Courtney, oh my gawd, this cake!!! I love Nigella. . and love meeting people like that. . where you have that instant connection. . my sister has all the seasons of Gilmore Girls too 🙂
Isn’t it wonderful to find a kindred spirit? Thanks for the love girl!
Is it possible to skip the hazelnuts or add less without it ruining the cake? The person I’m making this for has a minor nut allergy 🙁 can have some but not too much.
Unfortunately the hazelnut flour is really what keeps the cake together so I wouldn’t take it out or reduce it.
I’m a little worried…how big are “small” oranges? If I used ones too big or too small, won’t that effect the outcome?
Hi Alice, I wouldn’t worry too much about the size of the oranges. Look for average size oranges at your grocery store and you should be fine!
I can vouch for the fact that the size of the orange(s) doesn’t matter much. Nigella’s original recipe specifies “1 large or 2 small oranges” weighing ca. 14 oz total. I just made the cake today with an orange that weighed 10 oz. and it turned out just fine. The fact that this recipe is very forgiving makes it even better!
Came across this post while looking for this recipe, which I’ve made several times, to send to a friend. It’s fabulous.
However – the original version of this recipe in Nigella’s cookbook “Feast” specifies 2 cups of ground almonds, not hazelnut flour. Curious why you changed the ground almonds in the original recipe to hazelnuts … ?
Hello! There’s no particular reason, except that the first time I made this I had hazelnut meal I wanted to use up. I’ve made it with either almond or hazelnut since and both work wonderfully. I just go with whatever I have on hand.
Necessity really is the mother of invention! I just might try making it with hazelnut flour (which I love) next time to see if the flavor is different.
Excited for this crazy good looking cake! One question, do you remove the peels before blending? Or do you put the oranges with the peels into the blender after they’re boiled? Thanks!
They go in with the peel on! I know it sounds crazy but it really works! Hope you love it!
Cool! Starting to make it now! Thanks for the quick response 🙂
Really delicious, buy could def use a touch of salt! Would recommend adding a pinch.
In what alternative universe does this recipe fit into a blender? I mean, it technically fits, but fills it up so high that nothing can effectively be blended together. I had to scrape it out and use my stand mixer. Like an ordinary cake. Did you use some kind of magical industrial blender? I have a VitaMix Turbo Blend 4500, and there’s no way under heaven I could have effectively mixed this volume of ingredients in it.
Maybe your oranges are too large
I hve same mixer and works great
I’m excited to try this! Is it ok to bake the cake a day ahead, or best to make it the day of? If ahead is ok, should it be refrigerated over night??
You can definitely bake a day ahead! In fact, sometimes I think it’s even better the second day. Hope you enjoy!
Would it be okay if I used a 9-inch (24 cm) springform pan for this? I know it would be a little thinner, but would it drastically change the cake? Would I need to make any adjustments? If so, what? Thanks!
I think you could do that. I would just keep a close eye on it to make sure you don’t over bake it. You’ll probably need to reduce the baking time by 5-10 minutes.
This recipe is delicious and simple! I cut the sugar almost in half and it turned out very rich with an incredible orange essence. It’s a beautiful cake that can be dressed up many different ways. I made a raspberry/blueberry compote and drizzled it over the cake. Thank you! I will be making this again next week for my birthday!
I have made this cake several times – it is very good
However when i take it out from oven it has risen a good 3 to 4 inches and then falls down to 2 inches is this proper?
Why is it falling down
It’s normal for there to be some sinking. It’s definitely more of a dense cake than a fluffy cake.
Absolutely love love this cake! I have made it several times and it has turned out just awesome! I receive a lot of compliments when I make it. I frost mine with chocolate ganache with some orange zest on top-ah heaven!
The cake was delicious, honesy i had my doubts when i saw it, chocolate and orage, but it s sooo good!!! Can someone tell me if i can freez a piece or two? Would it have the same taste? Thanks for sharing 😊
I’m so glad you enjoyed it! The cake should freeze just fine. I’d wrap them tightly in saran wrap and place in a ziplock bag then thaw at room temp overnight. Thanks for making the recipe, and coming back to let me know!
Hello, if I do not have an 8- inch spring form pan, can I use a regular square pan and line it with wax paper? Thank you for your advice.
I think that would work, although you might not be able to get it as cleanly out of the pan. Serving it from the pan wouldn’t be a problem though.
This looks delicious!! I have some macadamia meal in the fridge – will this work? Also, I see you mention it is quite dense, will I still be able to construct it into a two/three layer cake sandwiched with maybe some dark choc mouse?
Thank you!
I think the macadamia meal would work! As far as layering, I think it would be a little heavy as a double layer cake. I think logistically you could stack it, but I probably wouldn’t recommend it. The mouse would make for a great frosting though!
This sounds delicious… Can you use a sugar substitute? Almond flour can be used too, right? I can’t have the sugar. I am going to try this my way to see how it turns out… I am going to use sugar free cake icing , micowaved till slightly runny. Then add some orange flavoring, then a light dusting of powdered sugar substitute.
I just made this cake for my daughter’s birthday tomorrow–should I put it in the fridge overnight? Thank you.
You can store it in the fridge or at room temperature. Either will be fine!
Thank you! It was delicious.
Hi,
I have baked this and love it.
I would like to make this into 2 x 6 inch round pans.
What would you suggest the baking time and the temperature?
Thank you so much, I am so excited waiting for your reply.
Had coconut flour so tried it instead of hazelnut flour with a Terry’s orange ganache. Turned out very well and so rich, it lasted 3 days as a dessert for 4. Delicious
So glad you enjoyed the chocolate orange cake! Thanks for sharing!
Can coconut sugar be used in the recipe instead of white sugar?
I’ve never baked with coconut sugar before, but the internet suggests you can make a 1-1 substitution with coconut sugar. This is a pretty sturdy cake, so my guess is that would work fine. Let me know if you give it a try!
Can I use walnuts instead of hazelnuts or almonds?
I’ve never tried this, but I would be concerned the walnuts would be too oily.
I just made this cake today, can’t wait to try it. My blender was not big enough for the full batch, I will have to spilt the batter next time. I made my own hazelnut meal. I started by toasting the hazelnuts before grinding them, hopefully that adds some nice flavor to the cake. I will be serving it with a orange zest infused crème anglaise.
I hope you loved the flourless chocolate orange cake! That creme anglaise sounds incredible.
I am currently in the midst of making this cake! thank you for sharing! I only have a small nutribullet blender so I have blended the oranges in that and will either do very tiny batches of the other ingredients OR just fold the orange in 🙂 So interested to try! Thanks again 🙂
Nigella’s recipe has 1/4 cup less sugar & vanilla. I think vanilla makes the cake! Maybe I used the wrong persons recipe & should have went for the original recipe from Nigella!!
Has anyone tried making this cake as a pan of individual cupcakes? Any advice/recommendations would be welcome if they have. Thanks
Can you substitute almond flour for the Almond meal?
Yes! They’re actually the same thing!
Hi, thank you the recipe looks great. I might try it this sunday for my mum-in-law’s 70th. Can I substitute the granulated sugar for dextrose? Do you think that will work ok? I often do for recipes, but want to be sure before I make this cake. Thank you.
Hi Rachel! I’ve never baked with dextrose before so I’m not much help with this question. If you experiment, please let me know how it turns out!
I will be baking this today right after my official work hours are over since it’s still a WFH! Thank you for sharing this recipe.
How much microwave chocolate ganache should I make in order to cover the top of the cake? Can’t wait to try
A cup should be plenty!
Wha a delicious cake! Was looking for something fun and different to make today that was chocolatey, dairy free and gluten free. This ticked all the boxes and then some! I had to check several times when I asked myself, “really? The whole
Orange?” Yes, yes and YES! It is Devine. Didn’t have spring form pan but came out just fine from a regular 8” cake pan. Dusted a pinch of cardamom in with powdered sugar on top. Thank you for such a delicious recipe. Will keep this one “in the mix” for a long time ☺️
I am so glad you enjoyed it! The whole orange threw me off at first too, but it really makes the cake!
I absolutely love Nigella,going to cook this for a dinner party.Also loved Anne of green gables , watched it n read it as a girl.will post a pic . Thanku for the great pics .BarbieB 👏💋
Hope you love it! Thanks for sharing!
Just another orange-boiling skeptic here to confirm that this stuff works!!!! Trust it! So simple and deeply delicious.
