These Peanut Butter Blondies with Marshmallows combine a peanut butter blondie base with classic Nutter Butter cookies and toasted marshmallows on top. Inspired by the peanut butter-and-marshmallow combination of a fluffernutter, they are nostalgic, delicious and easy-to-make.
Peanut Butter Blondies
- 3/4 cup dark brown sugar
- 1/4 cup salted butter, melted
- 1/3 cup creamy salted peanut butter
- 1 large egg
- 2 tsp vanilla extract
- 1 1/4 cup all purpose flour, or all purpose gluten free flour
Toppings
- 2-3 tbsp creamy salted peanut butter, for topping
- 4-5 nutter butter cookies
- 6 large marshmallows, halved, for topping
Preheat the oven to 350 degrees F.
Add the egg, brown sugar, butter and vanilla extract to a bowl.
Mix until combined.
Add in the creamy peanut butter and mix until combined.
Fold in the flour and mix until just combined.
Transfer to a square 8x8 baking pan that has been lined with parchment paper or greased.
Spread out the batter in an even layer.
Swirl in about 2-3 tbsp of creamy peanut butter on top and press 4-5 nutter butter cookies gently into the top of the blondie batter.
Bake in the oven for 28-30 minutes, then remove the pan from the oven when a toothpick comes out of the center clean or with a few crumbs. Turn the oven on Broil (High).
Add the large marshmallow halves (or mini marshmallows) on top. Gently press into the bars.
Put back into the oven and broil on High for about 1-2 minutes or until the marshmallows are perfectly toasted.
Remove from the oven. Let cool before slicing.
Slice into bars and enjoy!
