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
S’mores Layers
- 5 standard Hershey bars
- 1 1/2 cup Marshmallow fluff (or creme)
- Preheat and prepare pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set aside for later use.
- Cream butter and sugars: In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until well combined and creamy. Add in the egg and vanilla extract, mixing thoroughly until smooth.
- Combine dry ingredients: Add the all-purpose flour, finely crushed graham crackers, salt, and baking soda to the wet mixture. Mix gently until the flour mixture is fully incorporated and no streaks remain, being careful not to overmix.
- Form base layers: Press half of the cookie dough evenly into the prepared baking pan. Carefully lift the parchment paper with the dough and place it in the freezer to chill. While the first layer chills, re-line the baking pan with fresh parchment paper and press the second half of the dough evenly onto it.
- Assemble s’mores layers: Place the Hershey bars evenly over the dough in the pan, breaking pieces as needed to cover the surface completely. Spread the marshmallow fluff evenly over the chocolate layer. Retrieve the chilled dough layer from the freezer and gently flip it over onto the marshmallow fluff, pressing lightly to seal without breaking it.
- Bake and cool: Bake the assembled bars in the preheated oven for 25 minutes until golden and set. Once baked, allow the bars to cool completely in the pan before slicing to achieve clean bars and a perfect cross-section.
Notes
- Using parchment paper helps easily lift the cookie dough layers without sticking or breaking.
- Freezing the first dough layer helps when flipping it over and stacking the layers prevent cracking.
- Allow the bars to cool fully after baking to avoid the marshmallow layer oozing or melting too much when sliced.
- You can substitute classic Hershey bars with any milk chocolate or semi-sweet chocolate for a different taste.
- Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
