  • 2 1/2 cups all purpose flour
  • 1 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1/2 tsp cinnamon
  • 11 Tbsp (1 stick + 3 Tbsp) unsalted butter, room temperature
  • 1/2 cup granulated sugar
  • 1 cup light brown sugar, packed
  • 2 large eggs
  • 1 1/2 tsp vanilla extract
  • 1/3 cup semi-sweet chocolate chips
  • 1 cup mini marshmallows
  • 28 graham cracker squares
  • 28 Hershey bar pieces (from about 2.5 1.55-ounce Hershey Bars)
  1. In a medium bowl, whisk together flour, baking powder, salt, and cinnamon.

  2. In the bowl of a mixer, cream together butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 3-4 minutes. Add eggs and vanilla and mix until blended.

  3. Slowly add the flour mixture to the wet mixture, with the mixer on low speed, until it’s just combined, taking care not to over-mix.

  4. Fold in the chocolate chips and mini marshmallows until just combined. Chill the dough in the fridge for at least an hour and up to overnight.

  5. When ready to bake, pre-heat oven to 375 degrees.

  6. Line a baking sheet with parchment paper and lay graham cracker squares side-by-side. You may need two baking sheets if one is not large enough

  7. Place a scoop (a little more than 1 Tbsp) of cookie dough in the middle of each graham cracker and press down lightly with your finger. Put them in the oven for 5 minutes.

  8. Remove from oven and gently place a Hershey’s chocolate piece on top of each cookie.

  9. Put the cookies back in the oven for another 5-7 minutes, until cookies are just turning golden brown at edges.

  10. Let cool in pan a about 5 minutes and then remove to a wire rack to cool completely.
