Ingredients

The following ingredients have 16 Servings
  • 1/4 cup unsalted butter, room temperature
  • 1/2 cup natural peanut butter
  • 3/4 cup brown sugar
  • 1 egg, room temperature
  • 1 cup all purpose flour
  • 3/4 cup graham cracker crumbs
  • 1/2 teaspoon baking soda
  • 3/4 teaspoon salt
  • 2/3 cup chocolate (we used chopped up Hershey’s bars, but any chocolate will work!)
  • 2/3 cup mini marshmallows

Instruction

  • Preheat the oven to 350°F and line a square pan (9 x 9 or 8 x 8 will both work), with parchment paper. Set aside.
  • In a stand mixer fit with the paddle attachment, beat together the butter and peanut butter until homogenous. Don’t over mix.
  • Add the brown sugar and mix well. Scrape down the bowl and add the egg and vanilla extract. Mix until combined.
  • Scrape down the bowl and add the flour, graham cracker crumbs, baking soda, and salt. Mix until combined and no streaks of flour remain.
  • Add the marshmallows and chocolate pieces and fold once or twice to distribute throughout the batter. Transfer the batter to the prepared baking pan and pat into an even layer.
  • Bake for 20 to 30 minutes or until set on the edges and a knife inserted into the middle comes out mostly clean.  Allow to cool before slicing into 16 pieces. Enjoy!
