Ingredients Method Notes

Ingredients
  

Dough
  • 1/2 cup butter, softened
  • 1/4 cup packed brown sugar
  • 1/2 cup sugar
  • 1 egg
  • 1 teaspoon vanilla extract
  • 1 1/4 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 6 graham crackers, crushed into fine crumbs
Filling
  • 14 oz / 395 g (397 grams) milk chocolate bars
  • 7 oz / 200 g (198 grams) marshmallow cream
  • 1/2 cup peanut butter

Method
 

Preparation
  1. Heat the oven to 350°F / 175°C. Prepare a square baking dish by lining it with parchment paper.
  2. Beat the softened butter with the brown sugar and sugar until the mixture becomes light and fluffy.
  3. Add the egg and vanilla extract, then mix until fully incorporated.
  4. Combine the flour, baking powder, and salt with the wet mixture until a dough forms.
  5. Fold the crushed graham cracker crumbs into the dough.
  6. Press two-thirds of the dough evenly into the bottom of the prepared baking dish.
Assembly
  1. Arrange the milk chocolate bars over the dough layer.
  2. Warm the peanut butter in the microwave for about 30 seconds to make it easier to drizzle, then spread it over the chocolate.
  3. Distribute the marshmallow cream evenly over the peanut butter and chocolate layer.
  4. Roll out the remaining one-third of the dough on a nonstick surface and place it over the marshmallow cream layer.
Baking
  1. Bake the bars for about 30 minutes, until the top is golden brown.
  2. Allow the bars to cool completely before slicing into bars.

Notes

For cleaner slices, cool the bars completely before cutting and chill briefly if needed.
