Ingredients in Chocolate Chip Cake Mix Cookie Bars:

  • Yellow cake mix: I used one box of cake mix, but any kind can be used.
  • Butter: in order to turn cake mix into cookies, you need a fat, such as melted butter or vegetable oil. I prefer using butter, as it gives the bars are richer flavor.
  • Eggs: this acts as a binder and helps the gooey cake bars retain their rich flavor.
  • Vanilla
  • Chocolate chips: I used milk chocolate chips, but any kind will work.

How to Make Yellow Cake Mix Cookie Bars:

  • Mix: in a large mixing bowl, add the cake mix, melted butter, eggs, and vanilla. Stir well to combine. Gently fold in chocolate chips.
  • Spread: using a spatula, spread the batter evenly into a baking pan. The batter will be thick!
  • Bake: place into the oven and bake until golden brown. Allow the bars to cool completely and then slice.

How to Store:

Leftover chewy cookie bars will last in an airtight container at room temperature for up to five days.

To freeze: store in a freezer-safe container or bag for up to three months. When ready to serve, let thaw completely in the refrigerator.

Pro tip: warm a bar in the microwave for 10-15 seconds and then top with a big scoop of vanilla ice cream!

Tips and Variations for Making the Best Boxed Cake Mix Cookie Bars:

  • Don’t skip the cooking spray: be sure to use cooking spray or line the pan with parchment paper for easy removal once the bars are ready to serve.
  • For thicker bars: bake the batter in an 8×8 baking pan. The bars will bake up thick and chewy, though you will need to adjust the baking time.
  • Swap out the cake mix: for chocolate cake mix, strawberry cake mix, or white cake mix….the possibilities are endless!
  • Mix-ins: use dark chocolate chips, white chocolate chips, peanut butter chips, chopped nuts, or toffee bits for a fun flavor.
  • Toppings: just before baking, sprinkle extra chocolate chips on top; add some sprinkles; or swirl in some Nutella or peanut butter.
