Always Satisfying Oatmeal Chocolate Chip Bars

There are certain desserts I want on a special occasion: Chocolate Bundt Cake for my birthday, Sour Cream Cheesecake at Christmas, and Caramelized Apple Pie for Thanksgiving.

There are other desserts I could eat any day of the week, any time of year. Triple Chocolate Chip Cookies certainly fall under this category, and now I’ll add these Oatmeal Cookie Bars to the list as well.

These cookie bars are the kind of comforting, familiar treat you want to serve to your kids after a long day at school. They’re not too rich or too sweet, and the oatmeal gives them a hearty, chewy bite that pairs perfectly with a mug of cold milk.

Perhaps best of all, these Oatmeal Chocolate Chip Bars come together quickly with ingredients you probably already have on hand. They’re incredibly versatile and an excellent candidate for clearing out the pantry.

Start with chocolate chips, then experiment with whatever random bits and bobs you happen to have around. Add nuts, leftover Halloween candy, or dried fruit, or dress these up for the holidays with white chocolate chips and a scattering of festive sprinkles.

You can even try different mix-ins in the same pan! Have fun letting the whole family create their own perfect Chocolate Chip Oatmeal Bar.

How To Make Oatmeal Chocolate Chip Cookie Bars

After much testing, I found THE PERFECT oatmeal bar recipe, which comes together in a single pan, is buttery, slightly sweet, and has just a hint of cinnamon. Here’s how to make them!

  1. Preheat the oven to 350 degrees. Grease a 9 x 13 inch pan.
  2. In the bowl of an electric mixer, beat together butter, light brown sugar, granulated sugar, vanilla, cinnamon, salt, and cider vinegar until smooth.
  3. Add the eggs, beating after each addition, until the mixture is light and creamy.
  4. Sprinkle the baking soda and flour on top of the mixture and beat until combined, about 1 minute.
  5. Add the oats and chocolate chips or other additions, and stir to combine. Press the batter into the prepared pan.
  6. Bake for 32-35 minutes, or until edges are set, color is golden brown, and centers no longer look wet.

Tips for Perfect Oatmeal Bars

  • This recipe can easily be halved and baked in an 8 x 8 or 9 x9 inch square pan. Reduce the baking time to 24-27 minutes.
  • For the loveliest tops, stir 1 1/2 cups of the chocolate chips or other mix ins into the batter, then press the remaining 1/2 cup on top before baking.
  • If you want to cleanly remove the whole sheet of oatmeal bars, use a parchment sling. This makes it super easy to get neat and even cuts!
  • Wrap cooled oatmeal bars in saran wrap and store at room temperature. They’ll stay soft and chewy for 5 days!
  • These freeze well also! Check out this post for tips on freezing bar cookies.

Favorite Oatmeal Chocolate Chip Bar Variations:

This recipe can handle 2-2 1/2 cups of mix ins. I like to start with 1 cup of semi-sweet chocolate chips, then add other flavors, but you can forego the chocolate chips entirely if you wish!

  • Pecans + Dried Cherries + Dark Chocolate Chips– a rif on these Salted Milk Chocolate Cherry Oatmeal Cookies!
  • Caramel Chips + Chocolate Chips + Chopped Pretzel– this one ended up being a favorite of mine!
  • Christmas Cookie Bars– White Chocolate Chips + Christmas Sprinkles
  • Chocolate Chips + M&Ms
  • Oatmeal Raisin Cookie Bars– Increase the cinnamon to 1 1/4 teaspoon and add 1/2 cups raisins, soaked in warm water or orange juice for 10 minutes, then drained before stirring into the batter

To make different variations in the same batch, add 1 cup of chocolate chips to the batter, press it into the pan, then press different mix-ins onto the top in rows.
