How To make The Base Layer

• Preheat the oven to 350°F. Line a 9X15 inch pan with parchment paper, and grease with oil spray.
• Sift the flour, baking powder, and salt. Add the graham cracker crumbs.
  1⅓ cup All-purpose flour, 1 teaspoon Baking powder, ¼ teaspoon Salt, ¾ cup Graham cracker
• Cream the butter and sugar until light and fluffy.
  ½ cup Butter, ½ cup Sugar
• Then add the egg and vanilla and mix well.
  1 Egg, 1 tablespoon Vanilla extract
• Add the dry ingredients to the butter mixture and mix. The dough will have the consistency of the play dough.
• Save ½ cup of the dough for the topping, press the dough on the bottom of the prepared pan, and spread evenly.
• Place the chocolate bars over the dough and cover the surface completely.
  5-6 Milk chocolate bars
• Spread the marshmallow fluff all over the chocolate. This part is a bit messy and sticky.
  1 jar Marshmallow fluff
• Scatter the reserved ½ cup dough in form of clusters over the marshmallow fluff.
• Bake for 25-30 minutes, until the top, is golden. Let cool in the pan for 30 minutes and then transfer to the cooling rack. Let cool completely before cutting.
