Peanut Butter Cup Cookie Bars

Peanut butter cup cookie bars filled with mini peanut butter cups, chocolate sandwich cookies, and semi-sweet chocolate chips. Good luck just eating one of these delicious cookie bars!

I knew I wanted to get creative with the traditional blondies recipe and branch out to add more fun and flavor. I have found it with these cookie bars. They are perfectly cakey and bursting with flavor. If you’re in love with peanut butter cups like I am, you should also try this recipe for no-bake peanut butter cups.

The mini peanut butter cups get just a little melty fresh out of the oven and the chopped chocolate sandwich cookies add an extra texture that move these peanut butter cup cookie bars up to rock star status. I even warmed one of the cookie bars up and served it over vanilla ice cream after an especially long day. I ate it too quickly to take a picture, sorry.

This dessert is made in a 9×13 inch pan. It feeds a crowd (if you want it to), so it’s a great option if you need to bring something to a dinner party, barbecue, etc. Or you could just hoard them at home like I did. 😉
