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
- 1/2 tsp baking soda
Fillings
- 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 ensure easy removal.
- Cream butter and sugars: In a mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This step is crucial for a tender crumb.
- Add egg and vanilla: Beat in the egg and vanilla extract thoroughly until well combined, creating a smooth batter base.
- Add dry ingredients: Gradually mix in the all-purpose flour, finely crushed graham crackers, salt, and baking soda just until combined. Avoid overmixing to keep the bars tender.
- Chill dough base: Press half of the dough into the prepared baking pan evenly, creating a firm base layer. Place the pan in the freezer for about 15 minutes to chill and firm up the dough.
- Layer chocolate and marshmallow: Remove the pan from the freezer and evenly spread the broken Hershey bar pieces over the chilled dough. Then spread the marshmallow fluff evenly on top of the chocolate layer to create the signature s’mores middle.
- Add top dough layer and bake: Gently flip the remaining dough layer over the marshmallow fluff, covering it completely. Bake the assembled bars in the preheated oven for approximately 25 minutes, or until the top is golden brown and set.
- Cool and serve: Allow the cookie bars to cool completely in the pan before slicing into squares. This ensures that the layers set properly and make clean cuts.
Notes
- Freezing the dough base before layering helps keep the marshmallow fluff from mixing into the dough when adding the top layer.
- Use parchment paper with overhang for easy removal from the pan.
- You can substitute Hershey bars with any milk chocolate bar of your choice.
- Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- For a toasted marshmallow flavor, briefly broil the bars after baking, watching carefully to avoid burning.
