- 6 tbsp unsalted butter, melted
For the Brownie Layer:
- ½ cup (1 stick) unsalted butter
- 1 cup granulated sugar

- ⅓ cup unsweetened cocoa powder
- ½ cup all-purpose flour
- ¼ tsp salt
- ¼ tsp baking powder
For the Topping:
- 2 cups mini marshmallows

Tools You’ll Need
- 8×8 or 9×9 inch baking pan
- Mixing bowls
- Whisk and spatula
- Measuring cups and spoons
- Parchment paper or nonstick spray
- Broiler or kitchen torch for toasting marshmallows
Step-by-Step Instructions
Step 1: Prepare the Pan and Oven
Preheat your oven to 350°F (175°C)
Line a baking pan with parchment paper or grease lightly
Step 2: Make the Crust
In a bowl, mix graham cracker crumbs, sugar, and melted butter until combined
Press mixture firmly into the bottom of the pan to form an even crust
Bake for 8 minutes, then set aside
Step 3: Make the Brownie Batter
In a medium saucepan, melt the butter over low heat
Remove from heat and whisk in sugar, eggs, and vanilla until smooth
Add cocoa powder, flour, salt, and baking powder
Stir until just combined—don’t overmix
Step 4: Layer and Bake
Pour brownie batter over the baked graham cracker crust and smooth out evenly
Bake for 22–25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs
Remove from oven and let cool for 10–15 minutes
Step 5: Add the Marshmallow Topping
Sprinkle marshmallows evenly over the cooled brownie layer
Place under the broiler for 1–2 minutes, watching closely, until marshmallows are golden brown and toasted
Alternatively, use a kitchen torch for precise toasting
Step 6: Cool, Slice, and Serve
Allow brownies to cool completely before slicing for clean edges
Use a knife sprayed lightly with cooking spray to cut through the sticky topping
Tips for Perfect S’mores Brownies
Line the Pan – Parchment makes removal and cleanup easy
Watch the Broiler – Marshmallows toast quickly; don’t walk away
Use a Torch – Great for a campfire look and extra control
Chill Before Slicing – For cleaner cuts and neater squares
Double the Recipe – These disappear fast, especially at parties
