Ingredients

  • ½ cup butter room temperature
  • ½ cup sugar
  • ¼ cup brown sugar
  • Large egg
  • 1 teaspoon vanilla
  • 1 ¼ cups flour
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 6 graham crackers crushed to crumbs
  • 25 mini Reese’s Peanut Butter Cups
  • ½ cup creamy peanut butter
  • 4 cups mini marshmallows

Instructions

  • Preheat oven to 350º Fahrenheit.
  • In a medium mixing bowl, beat butter and sugars together.
  • Add egg and vanilla and mix well.
  • Beat in flour, baking powder, and salt.
  • With a mixing spoon, stir in graham cracker crumbs.
  • Line an 8x8 baking dish with parchment paper.
  • Press half of the crust mixture into the baking dish.
  • When you have it flat, gently grab the parchment paper and lift the top layer out of the baking dish. Set it aside.
  • To create the bottom layer, line the baking dish with parchment paper again and press the remaining dough into the bottom.
  • Spread the peanut butter over the top (I like to microwave the peanut butter for 10-15 seconds, so it is easier to spread).
  • Evenly place the Reese’s Peanut Butter Cups on the bottom layer.
  • Sprinkle marshmallows on top.
  • Cover with the remaining layer of crust.
  • Bake for 30 minutes or until top is golden brown.

Notes

  • Try substituting your peanut butter with Nutella. 
  • Heating the peanut butter in the microwave for 15 seconds makes it easier to spread.
  • Allow your S’mores bars cool before cutting into them.
