Ingredients

  • 2 cups all purpose flour
  • 2 cups graham cracker crumbs
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1 cup unsalted butter at room temperature
  • 1 1/2 cups light brown sugar packed
  • 2 large eggs lightly beaten
  • 2 cups mini marshmallows heaping
  • 1 1/2 cups semi-sweet chocolate chunks a bit more if using chocolate chips

Instructions

  1. Preheat oven to 350 F. and grease and line a 9x13 baking pan with parchment paper, ensuring that the paper along the long sides extends above the pan a bit, to act as handles to remove from the pan later. Set aside.

  2. In a large bowl, whisk together the flour, graham cracker crumbs, baking powder and salt. Set aside.
  3. In a large bowl with an electric mixer or in the bowl of a stand mixer with a paddle attachment, beat together the butter and brown sugar until light and fluffy, about 2 minutes. Scrape down sides of bowl. Add eggs and beat until well combined. Reduce mixer to low and slowly beat in the flour mixture until combined.
  4. Remove and set aside about 1/4 of the dough. Press the remaining dough into the prepared pan to form a thin, even layer on the bottom of the pan. Top with chocolate chunks, then marshmallows. Scatter the reserved dough over-top in clumps. It won't/shouldn't cover the entire top, as you want the chocolate and marshmallows to show through the top.
  5. Bake in preheated oven until golden brown, about 30-35 minutes. Set pan on a wire rack to cool completely, then lift out of pan by grabbing the parchment paper. Remove to a cutting board. Trim the outside edges, if desired, then cut into squares.
