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
Filling and Topping
- 5 standard Hershey bars
- 1 1/2 cup Marshmallow fluff
- Preheat and Prepare Pan: Preheat the oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set aside.
- Cream Butter and Sugars: In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until well combined and fluffy. Add the egg and vanilla extract, mixing again until fully incorporated.
- Add Dry Ingredients: Add the all-purpose flour, finely crushed graham crackers, salt, and baking soda to the wet ingredients. Mix gently just until the flour mixture disappears and everything is combined, being careful not to overmix.
- Form Dough Layers: Press half of the cookie dough evenly into the prepared baking pan. Carefully remove the parchment paper with the dough and place it in the freezer to chill. Re-line the pan with fresh parchment paper and press the remaining dough into another layer, then refrigerate or keep aside.
- Assemble Bars: Place the chocolate bars evenly over the dough in the pan, breaking pieces as needed to cover the surface fully. Spread the marshmallow fluff evenly over the chocolate layer. Then gently flip the chilled cookie dough layer from the freezer on top of the marshmallow layer, taking care to keep it intact.
- Bake: Bake the assembled bars in the preheated oven for 25 minutes until lightly golden and set.
- Cool and Slice: Allow the s’mores cookie bars to cool completely in the pan before slicing to ensure clean cuts and maintain the layered cross section.
Notes
- Freezing the dough layer before assembly helps prevent the bars from becoming too messy while flipping and layering.
- Use parchment paper to easily lift and flip the dough layers without breakage.
- Allow bars to cool fully before slicing for best presentation and texture.
- Hershey’s standard milk chocolate bars are recommended for authentic flavor, but you can substitute with your favorite chocolate.
- Store bars in an airtight container at room temperature for up to 3 days.
