Ingredients

  • 1/2 cup butter room temperature
  • 1/2 cup sugar
  • 1/4 cup brown sugar
  • 1 large egg
  • 1 teaspoon vanilla
  • 1 teaspoon baking powder
  • 1 1/4 cup flour
  • 1 teaspoon salt
  • 6 graham crackers crushed
  • 2 chocolate bars I used Hersheys
  • 25 marshmallows or 7-oz jar of marshmallow creme

Instructions

  • Preheat the oven to 350°F. Line an 8x8-inch baking pan with parchment.
  • Cream together butter and sugar until light and fluffy. Add the egg and vanilla and mix. Then add the dry ingredients: flour, baking powder, salt and crushed graham crackers.
  • Press 1/2 of the graham dough into the bottom of the prepared 8x8 baking pan. Lift out the parchment with the graham dough on it and set aside. This is the top layer.
  • Then, line the baking pan with a second parchment paper and press the remaining dough in the bottom. This will be your bottom layer. Top with chocolate bars and marshmallows. I like to lay them on their sides. Finally, cover with the top layer of graham dough you set aside.
  • Bake for 30 minutes or until golden brown. Cool completely before cutting as they will be very gooey!
