Instructions
 

  • Preheat the oven to 350℉/180℃. Grease an 8×8 inch square pan. For easy removal of the bars, place parchment paper on the bottom and 2 sides of the pan. Grease again and then set side.
  • Brown the butter: Melt the butter in a medium sized pan over medium heat. Once it melts, it will crackle, then become foamy – continue mixing the butter while this happens to prevent burning. The butter will go from melted to golden brown quickly, and you'll know it's almost done when the aroma of browned butter arrives. The whole process should take about 5 minutes! Once golden, remove from heat and transfer to a glass bowl. Let the butter cool for 30 minutes (Do not let it harden) while you prep on the rest of the recipe.
    1/2 cup butter
  • In a large mixing bowl, add cooled browned butter, brown sugar, and peanut butter. Mix until combined.
    3/4 cups dark brown sugar, 1/3 cup creamy peanut butter
  • Add in egg, egg yolk, and vanilla. Whisk until light and fluffy (2-3 minutes).
    1 egg, 1 egg yolk, 1 tbsp vanilla
  • Toss in the flour, baking soda, baking powder, salt, and graham cracker crumbs. Using a spatula, gently fold until well combined and a soft dough forms.
    1 3/4 cups all-purpose flour, 1/4 tsp baking powder, 1/2 tsp baking soda, 1/4 tsp salt, 4 tbsp graham cracker crumbs
  • Add in 3/4 cups of chocolate chips and mix in.
    1 cup semi-sweet chocolate chips
  • Take 3/4's of the cookie dough and spread it along the bottom of your prepared pan. Make sure the entire bottom is covered well!
  • Spread marshmallow fluff evenly on top. This can be tricky, so place smaller spoonfuls of it onto the dough and that will make it easier to spread around.
    1/2 cup marshmallow fluff
  • Sprinkle chocolate chips and graham crackers on top. Using your hands, flatten the remaining 1/4 of the peanut butter dough and randomly place on top of the bars. Leave some holes in between for the ribbons of marshmallow fluff to peak through!
    1/2 cup graham crackers
  • Bake for 25-30 minutes. You'll know it's ready when the edges are a light golden brown colour. The marshmallow fluff may rise up, but it should flatten once removed from the oven and cooled off.
  • Slice and enjoy!
