Banana Crumble Cake is a soft and crumbly coffee cake thatโ€™s loaded with cinnamon crumbles inside and out.

Wake up to a sweet new day with a warm slice of our Banana Crumble Cake for breakfast. This simple cake recipe takes everything you love about coffee cake, and adds enough bananas to basically qualify as a side of fruit.

The cinnamon and banana smells will beckon you to the breakfast table, and our cinnamon streusel crumb topping will delight you with every crumbly bite.

We love when breakfast features a sweet item that compliments a serving of savory Overnight Breakfast Casserole, some toasty Eggs in a Basket, or a slice of Quiche Lorraine

The great thing about this Banana Crumble Cake is that itโ€™s just as good all by itself as it is alongside a full breakfast or brunch. Itโ€™s even a great dessert option (especially the leftovers when thereโ€™s vanilla iced cream in the freezer).

All About the Crumbs

The secret to this ultra moist cake is the layer of crumbs in the middle. Brown sugar, butter, and cinnamon crumb combine to make both the filling and the topping. The crumbs in the center disappear during baking, leaving their buttery, spicy warmth behind. 

The crumbs on top get golden brown and crunchy, forming the perfect crispy crumb topping.

This banana coffee cake is definitely sweet enough as is, but we like to top it off with a drizzle of cream cheese frosting. This glaze melts into all the nooks and crannies making this cake so good that you might find yourself letting bananas rot just so you can make it.

Why Youโ€™ll Love Banana Crumble Cake

  • Itโ€™s a great way to use up those overripe bananas. We all know the drill, you buy a bunch of bananas, they sit there looking hard and green until all of the sudden, one day you wake up to a mushy browning mess. No problem! Like with our Sour Cream Banana Bread, or our Double Chocolate Banana Bread recipes, the riper the bananas, the sweeter this Banana Crumble Cake will taste.
  • Easy to make. Thereโ€™s nothing special or out of the ordinary here, so with just a few baking staples, and about 30 minutes of prep time, youโ€™ll be on your way to making and eating this banana coffee cake.
  • Smells and tastes amazing. Waking up to the smells of warm buttery cinnamon and banana cake is like a good morning hug. 
  • Thereโ€™s plenty to share. This banana cake makes a whole 9โ€x13โ€ dish, so there will be enough for you and 19 of your closest breakfast buddies.

Absolutely LOVED this recipe!! It turned out so soft and moist. I donโ€™t often have online recipes turn out as good as the pictures make them look, but this one sure did. Definitely a keeper for me, and I will be using it over and over!

  • Cinnamon, brown sugar, nutmeg – This sweet spices blend gives the crumbs in this cake its signature flavor.
  • Sugar and vanilla – Adds some sweetness.
  • Eggs – Youโ€™ll need 2 whole eggs for this banana crumb cake, so no splitting or having leftover egg yolks, or leftover egg whites here.

  • Flour, salt, baking powder – Standard baking fare.

Tips and FAQs

This Banana Crumble Cake was originally posted in 2016. Since then hundreds of you have tried this recipe and given us your feedback, and it is overwhelmingly a hit. (Still at 4.5 stars ~200 reviews) Though as beloved as it is, every recipe has some hangups…

This Banana Crumb Cake is too SWEET!

Most love this recipe as-is, but a common criticism is that this banana crumble cake is too sweet for certain tasters. If thatโ€™s you, reduce the granulated sugar in the cake batter by about ยผ cup and reduce the brown sugar by up to ยผ cup in the crumble topping. 

Other considerations on sweetness:

  • Bananas that are brown, mushy and overly ripe are sweeter.
  • Tree-ripened bananas are sweeter than those that ripen after theyโ€™re picked (*thanks to reader Aarti for that tip).
  • Also, weโ€™ve included a new Cream Cheese Drizzle as the new primary frosting. Itโ€™s less sugary, has just a slight hint of tang, and helps cut the sweet flavor of the rest of the cake a bit. Though if you still want the original powdered sugar glaze, itโ€™s down in the recipe notes.

My Crumble Topping Melted!

Make sure that you use COLD butter for the crumble topping. And maybe add just a tad more flour on your second try.

My Cake is Pudding Like / Too Dense!

While itโ€™s impossible to say for sure what caused this, I know from personal experience that forgetting the baking powder, or using baking powder that isnโ€™t fresh can cause this.

Also, are your bananas jumbo-sized? If so, maybe cut back a little on those.

What Goes With Banana Crumble Cake?

Banana Coffee Cake is the perfect punctuation at the end of a nice brunch. We love it best when weโ€™ve started the meal with a savory Eggs Benedict, Breakfast Sandwich or a protein packed Sweet Potato Breakfast Hash, accompanied by a Summer Berry Salad

It can easily stand on its own of course, but I would at least recommend enjoying it with a morning latte and maybe a slice or 2 of Oven Cooked Bacon.

Because it makes a whole dish, youโ€™re likely to have leftovers, so pair it with some ice cream, or a glass of milk for a great dessert.

Can you freeze the Banana Crumb Cake?

Yes. Just do so WITHOUT the glaze frosting and make sure to let the cake cool completely first.

Ingredients
 

For the cake:

  • 2 cups flour
  • 3 teaspoons baking powder
  • 1 teaspoon salt
  • 4 very ripe bananas
  • 1/2 cup butter (room temperature)
  • 2 cups granulated sugar
  • 2 eggs
  • 1 teaspoon vanilla
  • 1 cup milk

For the crumbs:

  • 1/2 cup cold butter, cubed (1 stick )
  • 1 cup light brown sugar
  • 1 cup flour
  • 1 teaspoon cinnamon
  • 1/2 teaspoon nutmeg

For the cream cheese drizzle:

  • 3 oz cream cheese
  • ยฝ cup powdered sugar
  • 2 tablespoons milk
  • Splash vanilla

Instructions

  • Preheat the oven to 350 degrees. Grease a 9 x 13 inch pan. In a small bowl, whisk together the flour, baking powder, and salt. In another large bowl, mash the bananas. Beat in the butter until well combined. The butter will likely not incorporate all the way and might look separated. This is just fine! Add the sugar, eggs, and vanilla and beat until combined.
  • Stir in the flour and milk alternately, beginning and ending with the milk. Set aside.
  • In another bowl, combine all of the crumb ingredients and use a pastry cutter or forks to cut in the butter until pea sized crumbs form.
  • Pour half of the cake batter into the prepared pan then layer with half of the crumbs. Pour the remaining batter on top followed by the rest of the crumbs. Bake in the preheated oven for 45-55 minutes or until a toothpick inserted in the center comes out clean.
  • Remove from oven and allow to cool for 10 minutes. Whisk together the glaze ingredients in a measuring cup then drizzle over the cake. Serve warm or at room temperature. Cake will keep for 3 days in a covered container, but the crumbs will lose their crunch after the first day.

Notes

  • To reduce the sweetness of this recipe, reduce the granulated sugar in the cake batter by about ยผ cup and reduce the brown sugar by up to ยผ cup in the crumble topping.
