Cookie Dough Ingredients

  • 1 cup unsalted butter, softened providing a rich and creamy base
  • 1 cup peanut butter the star of the show, offering a nutty and indulgent taste
  • 1 cup granulated sugar adding sweetness to balance the flavors
  • 1 cup brown sugar, packed for that deep, caramel-like richness
  • 2 large eggs binding the ingredients together, ensuring a chewy cookie
  • 1 tsp vanilla extract bringing aromatic notes that enhance the overall taste
  • 1.5 cups all-purpose flour creating a sturdy structure for the cookies
  • 1.5 cups graham cracker crumbs offers a crunchy texture reminiscent of s’mores
  • 1 tsp baking soda giving the cookies a perfect rise
  • 0.5 tsp salt intensifying the sweetness

Filling Ingredients

  • 1 cup mini marshmallows providing that classic gooeyness
  • 0.5 cups chocolate chips enriching the cookies with melty chocolate goodness
  • 0.25 cup peanut butter for a decadent filling that complements the cookies

Instructions
 

Preparation

  • Preheat your oven to 175°C (350°F) and line a baking sheet with parchment paper.
  • In a large bowl, cream together the softened butter, peanut butter, granulated sugar, and brown sugar until fluffy and smooth.
  • Add the eggs and vanilla extract to the mixture, mixing until well combined.
  • In another bowl, whisk together the all-purpose flour, graham cracker crumbs, baking soda, and salt.
  • Gradually add the dry ingredients to the wet mixture, stirring until a dough forms.
  • Scoop the dough into 1-inch balls and place them on the prepared baking sheet. Press down slightly to flatten each ball.

Baking

  • Bake the cookies in the preheated oven for about 10-12 minutes or until they are golden brown.
  • Let them cool on a wire rack.

Making the Filling

  • For the filling, melt the chocolate chips and peanut butter in a microwave-safe bowl. Heat in short intervals, stirring until smooth.
  • Stir in the mini marshmallows and let the filling cool slightly until it thickens.

Assembly

  • Spread a generous spoonful of the marshmallow-chocolate filling on top of one cookie.
  • Sandwich it with another cookie.

Notes

Consider using crunchy peanut butter for added texture and sprinkle a little sea salt on top of the filling before sealing. Store cookies in an airtight container to maintain softness.
