Step-by-step instructions

1. 1

   Prep: Preheat the oven to 350 degrees.

2. 2

   Cookie Base: Beat the butter and both sugars. Mix in the egg and vanilla. Mix in the flour, baking powder, and salt. Stir in the graham cracker crumbs.

3. 3

   Make a top layer: Line an 8×8 baking dish with parchment. Press half of the dough into the bottom of the pan. Lift out the parchment with the dough on it and set it aside – this will be your top cookie layer .

4. 4

   Assembly: Line again with parchment and press the remaining dough into the bottom of the pan. Layer with the chocolate bars, peanut butter, and marshmallow creme.

5. 5

   Final Layer: Gently flip and place the prepared top cookie layer onto the top of the bars and peel the parchment off the top.

6. 6

   Bake: Bake for 30 minutes until the top is golden brown.

7. 7

   Resting Time : For the cleanest slices, I like to let the bars rest for 4-6 hours or give them a bit of time in the fridge so they can solidify enough for a clean cut! More info in the notes.
