Graham Cookie

  • 2 1/2 cups all purpose flour
  • 2 tsp baking powder
  • 1 1/2 tsp salt
  • 1 cup butter {softened}
  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 eggs
  • 2 tsp vanilla extract
  • 1 1/4 cups graham cracker crumbs

Fudge Layer

  • 1 14 oz. can sweetened condensed milk
  • 12 oz. milk chocolate chips
  • 3 tbsp butter
  • 35-40 mini marshmallows


  1. Preheat oven to 350° and spray a 9x13 pan with non-stick spray.

  2. In a small bowl combine flour, baking powder and salt, set aside. In a medium bowl combine butter, brown sugar, granulated sugar, eggs and vanilla until creamy {I like to use a hand held mixer but this can be done by hand}. Add flour mixture and stir to combine. Add the graham cracker crumbs and combine. Press 2/3 of the graham dough into the bottom of your prepared pan, reserve the remaining 1/3 for the top.

  3. Combine sweetened condensed milk, milk chocolate chips and butter in a medium microwave safe bowl and microwave for 2 minutes. Stir and add 30 second increments until the mixture is smooth. Pour over the graham layers and spread out into an even layer. Top with marshmallows. Crumble remaining 1/3 of graham dough over the top of the marshmallows.

  4. Bake your S'Mores Cookie Bars for 25-30 minutes or until the bars are cooked through but not over baked. Remove from oven and cool completely on a cooling rack. Cut into squares and serve. Store leftovers in an air tight container for up to 5 days.
