Peanut Butter Cookie Crust

  • 1 cup (258g) peanut butter, creamy or crunchy
  • ½ cup (100g) granulated sugar
  • ½ cup (100g) brown sugar
  • 1 large egg, room temperature
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla
  • 1 pinch salt
  • 2 cups miniature marshmallows

Peanut Butter Sauce

  • ½ cup (129g) peanut butter, I use chunky
  • ½ cup (1 stick or 113g) unsalted butter
  • ½ cup (85g) butterscotch chips


Peanut Butter Cookie Crust

  • Preheat oven to 350°F (175°C).
  • Place a piece of parchment paper on a 12-inch round pizza pan.
  • In a medium bowl, stir peanut butter and sugars together until smooth. Beat in the egg. Then stir in the baking soda, vanilla, and salt.
  • Place the cookie dough on parchment paper-lined pizza pan. Get out another piece of parchment paper and lay on top. With a rolling pin, flatten out peanut butter dough to fit the 12-inch pizza pan. Remove the top piece of parchment paper.
  • Bake for 8-10 minutes or until the center does not look wet. (Slightly underdone is okay, as you will be placing it back into the oven.) As the crust is finishing baking, make the peanut butter sauce.

Peanut Butter Sauce

  • In a medium saucepan, melt butter and peanut butter over medium low heat. Once they are fully melted and combined, add in butterscotch chips. Remove from heat and stir continually until mostly melted.
  • There will be chunks in the bottom of the pan, this is okay. Set aside to cool slightly.


  • Remove peanut butter crust from oven and immediately place mini marshmallows evenly over the crust.
  • Turn oven to broil then put the crust with marshmallows back into oven. Watch closely and remove after about 1 minute, or right when the marshmallows start to turn golden.
  • Pour peanut butter sauce over marshmallows.
  • Pizza can be served immediately. (Best served warm or at room temperature)
