Ingredients
Scale
Cookie Dough
- 1/2 cup butter, softened, salted or unsalted
- 1/3 cup brown sugar
- 1/4 cup granulated sugar
- 1 egg
- 1 tsp vanilla extract
- 1 1/2 cup all-purpose flour
- 1/2 cup graham crackers, finely crushed (about 3.5 sheets)
- 1/4 tsp salt
- 3/4 tsp baking soda
Assembly
- 5 standard Hershey bars
- 1 1/2 cup marshmallow fluff
Instructions
- Preheat and prepare pan: Preheat the oven to 350 degrees Fahrenheit. Line an 8×8 inch baking pan with parchment paper and set aside.
- Cream wet ingredients: In a mixing bowl, cream the softened butter, granulated sugar, and brown sugar together until well combined. Add the egg and vanilla extract, mixing thoroughly to combine.
- Add dry ingredients: Gradually incorporate the all-purpose flour, crushed graham crackers, salt, and baking soda into the wet mixture. Mix just until the flour mixture disappears and the dough comes together.
- Form base layers: Press half of the cookie dough evenly into the prepared baking pan. Carefully lift this parchment paper with the dough and place it in the freezer. Re-line the pan with fresh parchment paper and press the remaining dough evenly into the pan.
- Add chocolate and marshmallow layers: Break the Hershey bars into pieces and evenly distribute them over the dough layer in the pan. Spread the marshmallow fluff evenly on top of the chocolate layer. Remove the chilled dough from the freezer and carefully flip it on top of the marshmallow layer, working carefully to keep it intact.
- Bake the bars: Bake in the preheated oven for 25 minutes until golden and set.
- Cool and serve: Allow the bars to cool completely before slicing into 16 squares to achieve clean slices and showcase the beautiful layers.
Notes
- Use either salted or unsalted butter depending on preference; if using unsalted, you may add a pinch more salt if desired.
- Freezing the bottom layer of dough helps maintain structure and prevents the marshmallow from melting into the dough when assembled.
- You can substitute Hershey bars with other milk chocolate bars if preferred.
- For easier slicing, chill the bars in the refrigerator after cooling to let layers firm up more.
- Make sure to spread marshmallow fluff gently to avoid tearing the dough.
