Chocolate Cake Mix Bar Cookies: Easy Bar Cookie Recipe

Chocolate Cake Mix Bar Cookies are the perfect marriage between chocolate and peanut flavors … and it is an easy bar cookie recipe.

Two factors make this recipe so simple. First, it calls for you to use a chocolate cake mix to make the crust. With just a few flips of a fork to mix the crust together, you’re all set to press it into the pan.

Second, these bars are super easy to assemble. You pour the rest of the ingredients on top of the crust and poof! The bars go into the oven.

And the bars freeze well.

If you like the combination of chocolate and peanut butter – and you like to save steps –  this simple cookie recipe is for you.
