Something magical happens when you mix peanut butter and chocolate together. Combine that with just enough crunch and these Chocolate Peanut Butter Bars are drool-worthy, crave-worthy, and completely addictive!

Please tell me if you can eat just! I can’t.

Just look at that thick ribbon of chocolate. And, the crust is buttery with a little crunch and texture.

If you’ve been following me, you know I’m all about quick and easy! Using a cake mix for the crust and topping makes the prep time for these bars very quick. Furthermore, the hardest part is waiting for them to cook.

If you want really pretty squares, you’ll need to wait until they cool completely or even chill them in the refrigerator to get those perfect, bakery-style cuts. However, if that isn’t a priority to you, dive right in as soon as they’re cool enough to handle!
