For the Brownie Layer:
- ½ cup (1 stick) unsalted butter
- 8 oz semi-sweet chocolate, chopped (or chocolate chips)

- 1 teaspoon vanilla extract
- ½ cup all-purpose flour

For the Topping:

Cooking Directions
- Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy lifting.
- Make the crust: Combine graham cracker crumbs, melted butter, and sugar. Press evenly into the bottom of the pan. Bake for 8 minutes, then cool slightly.
- Prepare the brownie batter: Melt butter and chocolate together. Stir in both sugars, then add eggs and vanilla. Mix in flour, cocoa powder, and salt until just combined.
- Assemble: Pour the brownie batter over the graham crust and spread evenly.
- Bake for 25–30 minutes, or until a toothpick inserted in the center comes out mostly clean.
- Add toppings: Sprinkle marshmallows, chopped chocolate, and crushed graham crackers over the warm brownies.
- Broil for 1–2 minutes, watching closely until marshmallows are golden brown.
- Cool completely before slicing into squares.
Step-by-Step Preparation Method
Step 1: Prepare the Pan
Preheat oven to 350°F (175°C). Line your baking pan with parchment paper.
Step 2: Make the Graham Crust
Mix graham cracker crumbs, melted butter, and sugar until evenly coated. Press into the bottom of the pan using the back of a spoon. Bake for 8 minutes and let cool.
Step 3: Prepare the Brownie Batter
In a microwave-safe bowl, melt butter and chocolate in 20-second intervals, stirring between each. Whisk in sugars, then eggs and vanilla. Add flour, cocoa powder, and salt, mixing until smooth.
Step 4: Assemble the Layers
Pour the brownie batter over the crust and spread evenly to the edges.
Step 5: Bake the Brownies
Bake for 25–30 minutes. The center should be set but still fudgy.
Step 6: Add the S’mores Topping
While still warm, sprinkle mini marshmallows, chocolate, and crushed graham crackers. Return to the oven on broil for 1–2 minutes until marshmallows are lightly browned.
Step 7: Cool and Slice
Cool completely before cutting into bars. For clean cuts, chill for 15–20 minutes before slicing.
