Ingredients
Scale
Cookie Base
- 1/2 cup softened butter
- 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 finely crushed graham crackers (about 3.5 sheets)
- 1/4 tsp salt
- 1/4 tsp baking soda
Filling
- 5 standard Hershey bars (broken into pieces)
- 1 1/2 cups marshmallow fluff
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and line an 8×8 inch baking pan with parchment paper to prevent sticking and for easy removal of the bars.
- Cream Butter and Sugars: In a mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture becomes light, fluffy, and well-combined. This ensures a tender cookie base.
- Add Egg and Vanilla: Beat in the egg and vanilla extract until fully incorporated, adding moisture and flavor to the dough.
- Mix Dry Ingredients: Gradually add the all-purpose flour, finely crushed graham crackers, salt, and baking soda into the wet ingredients. Mix until just combined to avoid overworking the dough and maintaining tenderness.
- Press First Layer and Chill: Press half of the cookie dough evenly into the prepared baking pan. Place the pan in the freezer for about 15 minutes to firm up the dough, making it easier to layer the filling without mixing.
- Add Chocolate and Marshmallow Layers: Evenly layer the broken Hershey bar pieces on top of the chilled dough base. Then, spread the marshmallow fluff evenly over the chocolate, creating the gooey middle layer characteristic of s’mores.
- Add Top Layer and Bake: Flip the remaining dough layer on top of the marshmallow layer, covering the filling completely. Bake the assembled bars in the preheated oven for approximately 25 minutes, or until the top is golden brown and the bars are set.
- Cool and Slice: Remove from the oven and allow the cookie bars to cool completely in the pan on a wire rack. Once cooled, slice into squares and serve.
Notes
- For easier spreading, warm the marshmallow fluff slightly before layering.
- Freezing the bottom dough layer helps prevent the filling from sinking and mixing too much during assembly.
- Use parchment paper extending beyond the edges of the pan to lift out bars easily for slicing.
- Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
- For a nuttier twist, consider adding chopped nuts to the cookie dough base.
