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 cups All-purpose flour
- 1/2 cup Graham crackers (finely crushed, about 3.5 sheets)
- 1/4 tsp Salt
- 3/4 tsp Baking soda
Filling & Topping
- 5 standard Hershey bars
- 1 1/2 cups Marshmallow fluff
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set it aside to prepare the dough layers.
- Cream Butter and Sugars: In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is smooth and combined. Add the egg and vanilla extract, mixing again until incorporated.
- Mix Dry Ingredients: Add the all-purpose flour, crushed graham crackers, salt, and baking soda to the wet ingredients. Mix gently just until no flour streaks remain; avoid overmixing to keep the dough tender.
- Form Base Dough Layer: Take half of the cookie dough and press it evenly into the prepared baking pan. Then carefully remove the parchment paper with the dough from the pan and place it in the freezer to chill. Meanwhile, re-line the pan with fresh parchment paper and press the remaining dough into it for the top layer.
- Add Chocolate and Marshmallow Layers: Place the Hershey chocolate bars evenly over the dough in the pan, breaking pieces if necessary to cover the surface completely. Spread the marshmallow fluff evenly over the chocolate layer.
- Assemble Bars: Retrieve the chilled dough layer from the freezer and gently flip it over onto the marshmallow fluff layer, working carefully to keep it intact and properly aligned.
- Bake: Place the assembled pan in the preheated oven and bake for 25 minutes until golden and set.
- Cool and Slice: Allow the bars to cool completely in the pan before slicing to ensure clean cuts and to showcase the layered cross-section beautifully.
Notes
- Using parchment paper helps in easy removal and flipping of the dough layers.
- Freezing the dough base before assembly prevents it from breaking during flipping.
- You can substitute the Hershey bars with any milk or dark chocolate bars you prefer.
- Make sure the bars are completely cool before slicing to avoid a gooey mess.
