My first decision was to use mini peanut butter cups - easier to cut through than the larger ones. Away I went - using Fluff - and this recipe is actually really easy. It seems like it should be harder than it is, but it's really not.
Peanut Butter Cup S'mores Bars
16 large/20 small squares
1/2 cup butter, room temperature
1/2 cup packed brown sugar
1/4 cup sugar
1 tsp vanilla extract
1 1/4 cups flour
1 tsp baking powder
1/4 tsp salt
1 cup graham cracker crumbs
1 bag mini peanut butter cups, unwrapped
1 jar marshmallow fluff
- Preheat oven to 350 degrees. Coat an 8x8 baking dish with cooking spray and set aside. In a medium bowl stir together flour, baking powder, salt and graham cracker crumbs. Set aside.
- In the bowl of an electric mixer beat butter and both sugars until fluffy. Beat in egg and vanilla until combined, scraping down sides as needed. With mixer on low, stir in dry ingredients mixture. Mix until incorporated.
- Spread 2/3 dough on to prepared baking sheet. Lightly press mini peanut butter cups into dough, then spread a good layer of fluff on top of peanut butter cups. On a piece of parchment paper, press remaining dough into a 8x8 square. Place dough on top of fluff and press down lightly.
- Bake for 30 minutes or until edges just begin to brown. Allow to cool overnight or for at least 8 hours.
