If you find yourself with way too much candy after trick or treating and fall parties this week, these cookie bars are a great way to use it up! I love making cookie bars to use up leftover candy.

Cookie bars are so easy to whip up and bake, and they just taste good! Thick, chewy and loaded with candy. . .what’s not to love?!

We don’t eat much candy around here, so if I get a bag of candy around the different holidays, I usually end up baking with half of it.

That’s what happened with my last bag of Reese’s peanut butter cups. If you don’t have Reese’s, peanut butter M&M’s or any other chocolate candy would work just as well.

I just happen to have a love for all things peanut butter and find myself stuffing as much peanut butter as possible into my baked goods, especially these peanut butter overload cookie bars.

That’s why you’ll find lots of peanut butter, lots of chopped peanut butter cups, and lots of peanut butter chips in the ingredient list! Mix them all together and you have a peanut butter lover’s dream cookie bar!

Tips for Making Peanut Butter Overload Cookie Bars

  • M&M’s and chopped Snickers bars work well in place of (or in addition to!) the chopped peanut butter cups.
  • Feel free to use either creamy or crunchy peanut butter.
  • The dough may appear to be dry, but should hold together when pressed. If you are using a natural peanut butter that is on the drier side, you may need to add up to 1 Tablespoon of milk to get the dough to hold together when pressed.
  • To keep the bars nice and chewy, do not over-bake. Bake just until the edges start to turn golden and the center is set. The bars will continue to set up as they cool.

  31. Beautiful recipe but I need a little help! I don’t have an 8×8 pan so I doubled the recipe and they taste amazing but are a bit dry and crumbly. Should I add more peanut butter or use less flour? Thank you!

    • I’m sorry they turned out dry! I would recommend using a bit more peanut butter, or if your peanut butter is on the dry side, add a couple of tablespoons of milk. Also, it may help to not cook them as long. I know that I’ve had bars like this dry out when I’ve cooked them a little too long. I hope that helps!
