Ingredients
  

Crust

  • ¾ cup flour
  • cup brown sugar packed
  • ¼ teaspoon baking powder
  • teaspoon baking soda
  • ½ teaspoon salt
  • 4 tablespoon unsalted butter softened
  • 1 teaspoon vanilla
  • 1 egg yolk

Filling

  • 2 cups mini marshmallows

Topping

  • cup corn syrup
  • 2 tablespoon unsalted butter
  • 1 teaspoon vanilla
  • 1 cup peanut butter chips
  • 1 cup salted peanuts
  • 1 cup rice krispies

Instructions
 

Crust

  • Preheat the oven to 350 degrees.
  • Prepare a 9 x 9 inch baking pan by lining it with parchment paper leaving an overhang on two sides.
  • Combine flour, brown sugar, baking powder, baking soda, and salt in a medium bowl.
  • Add softened butter to the mixture and use your hands to mix in into the flour mixture.
  • Add egg yolk and vanilla and mix until evenly combined. The mixture will be very crumbly.
  • Press into a 9 x 9 pan using a cup to press it tightly into the pan.
  • Bake for about 12-13 minutes until golden brown.
  • Remove the crust from the oven and immediately add the marshmallows to the crust, distributing them evenly.
  • Return to the oven for 2 minutes until the marshmallows start to puff up. Remove from the oven and set aside while you make the topping.

Topping

  • In a medium saucepan, over medium heat, combine corn syrup, butter, peanut butter chips and vanilla. Stir until just melted.
  • Add the peanuts and rice krispies and quickly stir together until combined.
  • Using 2 spoons, dollop the peanut topping over the top of the marshmallows. Gently spread the topping to completely cover the marshmallows.
  • Cool in the refrigerator for at least 45 minutes, covered. Once cool, cut into squares with a sharp knife.

Notes

  • Store in the refrigerator/cooler until ready to serve. 
  • Can be frozen for up to 2 months in an airtight container.
