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
Fillings and 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 for the cookie dough.
- 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 in the egg and vanilla extract, mixing again until well incorporated.
- Add Dry Ingredients: Stir in the all-purpose flour, finely crushed graham crackers, salt, and baking soda. Mix just until the flour mixture disappears and the dough comes together, taking care not to overmix.
- Form Dough Layers: Press half of the cookie dough evenly into the prepared baking pan. Carefully remove the parchment from the pan along with the dough layer, then place this dough on a flat surface inside the freezer to chill. Meanwhile, re-line the baking pan with fresh parchment paper and repeat pressing the remaining cookie dough into an even layer on this second parchment.
- Layer the Chocolate and Marshmallow: Break the Hershey bars into pieces and lay them evenly over the dough layer in the pan. Spread the marshmallow fluff evenly over the chocolate bars. Gently remove the chilled dough layer from the freezer and carefully flip it on top of the marshmallow layer, maintaining its shape to form a sandwich.
- Bake: Place the assembled cookie bars in the preheated oven and bake for 25 minutes, or until the cookies are golden and set.
- Cool and Serve: Allow the bars to cool completely in the pan before slicing to ensure clean cuts and a beautiful cross section showcasing the layers.
Notes
- For best results, use parchment paper to prevent sticking and to make removal easier.
- You can substitute the Hershey bars with your favorite chocolate bars, but classic milk chocolate is ideal for authentic s’mores flavor.
- Freezing the cookie dough layers helps maintain their structure when assembling the bars.
- Allow the bars to cool fully to avoid the marshmallow layer from running when cut.
- Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
