Imagine sitting around a crackling campfire, toasting marshmallows to golden perfection, sandwiching them between chocolate and graham crackers — that’s the spirit of S’mores. Now, imagine capturing that same magic in a rich, chocolatey brownie form. That’s exactly what S’mores Brownies deliver!

These decadent bars feature three heavenly layers: a buttery graham cracker crust, a fudgy brownie center, and a gooey marshmallow topping. The blend of textures — crisp, chewy, and fluffy — makes every bite a moment of pure dessert bliss.

Ingredients

For the Graham Cracker Crust:

  • 1½ cups graham cracker crumbs
  • 6 tablespoons unsalted butter, melted
  • 2 tablespoons granulated sugar

For the Brownie Layer:

  • ½ cup (1 stick) unsalted butter
  • 8 oz semi-sweet chocolate, chopped (or chocolate chips)
  • ¾ cup granulated sugar
  • ¼ cup brown sugar, packed
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup all-purpose flour
  • 2 tablespoons unsweetened cocoa powder
  • ¼ teaspoon salt

For the Topping:

  • 2 cups mini marshmallows
  • ½ cup chopped milk chocolate or chocolate chips
  • Crushed graham crackers (for garnish)

Cooking Directions

  1. Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy lifting.
  2. 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.
  3. 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.
  4. Assemble: Pour the brownie batter over the graham crust and spread evenly.
  5. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out mostly clean.
  6. Add toppings: Sprinkle marshmallows, chopped chocolate, and crushed graham crackers over the warm brownies.
  7. Broil for 1–2 minutes, watching closely until marshmallows are golden brown.
  8. 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.

How to Serve This Recipe

Serve S’mores Brownies:

  • Slightly warm for a gooey, melty experience.
  • With a scoop of vanilla or chocolate ice cream for extra indulgence.
  • Drizzled with chocolate or caramel sauce.
  • Cut into bite-sized squares for dessert platters or parties.

Recipe Tips

  • Watch closely while broiling — marshmallows can burn fast!
  • Use mini marshmallows for even melting and coverage.
  • For extra fudginess, don’t overbake the brownies.
  • Line the pan with parchment for easy removal and clean slices.
  • Add a pinch of espresso powder to the brownie batter for richer chocolate flavor.

Variations

  1. Peanut Butter S’mores Brownies:
    Swirl 2 tablespoons of peanut butter into the brownie batter before baking.
  2. Salted Caramel S’mores Brownies:
    Drizzle caramel sauce over the brownie layer before adding toppings.
  3. Nutella S’mores Brownies:
    Add spoonfuls of Nutella between the crust and brownie layer for extra decadence.

    Use both milk and dark chocolate chunks for a richer flavor.

    Swap the brownie base for blondie batter made with brown sugar and white chocolate chips.

Freezing and Storage

  • Room Temperature: Store in an airtight container for up to 3 days.
  • Refrigerator: Keeps well for up to 5 days.
  • Freezer: Wrap each brownie tightly in plastic wrap and freeze for up to 2 months. Thaw at room temperature before serving.

Tip: Avoid freezing with marshmallow topping if possible — it can become sticky upon thawing.

  • Whisk and spatula
  • Measuring cups and spoons
