Fudgy S’mores Brownies are an indulgent treat that layers a buttery graham cracker crust with rich, gooey chocolate brownie and toasted marshmallows, capturing all the nostalgic flavors of s’mores without the campfire.

Ingredients

  • 1 1/2 cups graham cracker crumbs
  • 6 tbsp unsalted butter, melted (for crust)
  • 2 tbsp granulated sugar (for crust)
  • 1/2 cup unsalted butter (for brownies)
  • 6 oz semi-sweet chocolate or chocolate chips
  • 1/4 cup unsweetened cocoa powder
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2/3 cup all-purpose flour
  • 1/4 tsp salt
  • 2 cups mini marshmallows or 1216 large marshmallows
  • Optional: extra graham cracker pieces and chocolate chunks for topping

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper.
  2. Mix graham cracker crumbs, melted butter, and 2 tbsp sugar. Press firmly into the pan to form a crust. Bake for 8–10 minutes until lightly golden. Let cool slightly.
  3. In a saucepan or microwave-safe bowl, melt butter and chocolate until smooth. Stir in cocoa powder, granulated sugar, brown sugar, eggs, and vanilla extract until glossy.
  4. Fold in flour and salt just until combined. Do not overmix.
  5. Pour brownie batter over cooled crust and spread evenly.
  6. Bake for 25–30 minutes, or until a toothpick comes out with moist crumbs.
  7. Remove from oven and top with marshmallows. Broil for 1–2 minutes until toasted—watch carefully to avoid burning.
  8. Press extra graham cracker pieces and chocolate chunks into the warm marshmallows if using.
  9. Cool completely in the pan before slicing into 16 squares.

Notes

  • Use a boxed brownie mix for convenience; follow box instructions for batter.
  • Mini marshmallows provide more even coverage and easier slicing.
  • For a nutty twist, swirl in peanut butter or add peanut butter chips.
  • Cool completely before cutting for clean slices.
  • Use a kitchen torch instead of broiler for extra gooey topping.
