What Does This Dessert Taste Like?
Imagine the flavor of a warm chocolate chip cookie crossed with a gooey peanut butter cup.
The chocolate becomes soft and melty while the peanut butter centers turn rich and creamy.
Depending on how long you let the dessert cool, you can get everything from a warm, spoonable treat to thicker bars that can be sliced and served individually.
It’s sweet, buttery, chocolaty, nutty, and wonderfully gooey.
Basically, this is not the dessert to make when you're planning to “just have one bite.”
Good luck with that!

What Kind of Peanut Butter Cups Should You Use?
Mini peanut butter cups are ideal because they're small enough to distribute throughout the baking dish while still giving you those wonderful pockets of peanut butter and chocolate.
Make sure they're unwrapped before adding them to the dish.
You can use regular milk chocolate peanut butter cups or experiment with other varieties if you want to change the flavor.
