Print Recipe

A fun, shareable dessert combining fudgy brownies with toasted marshmallows and graham crackers, perfect for gatherings and nostalgic sweet cravings.

Ingredients

Scale
  • 1 cup (226g) unsalted butter, melted
  • 1 ½ cups (300g) granulated sugar
  • ¾ cup (150g) pure maple syrup
  • 4 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (85g) unsweetened cocoa powder
  • 1 cup (125g) all-purpose flour (or almond flour for gluten-free)
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (60g) crushed graham crackers
  • 2 cups (160g) mini marshmallows
  • Additional graham cracker pieces for garnish (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan with butter or line it with parchment paper.
  2. In a medium bowl, sift together cocoa powder, flour, baking powder, and salt. Set aside.
  3. In a large bowl, whisk melted butter, granulated sugar, and maple syrup until smooth and glossy. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract.
  4. Slowly fold the dry mixture into the wet ingredients using a rubber spatula until no flour streaks remain.
  5. Fold in the crushed graham crackers evenly throughout the batter.
  6. Pour batter into the prepared pan and smooth the top with a spatula.
  7. Bake for 30-35 minutes, checking at 30 minutes with a toothpick; it should come out with a few moist crumbs but not wet batter.
  8. Remove brownies from oven and immediately sprinkle mini marshmallows evenly over the top.
  9. Switch oven to broil and place pan about 6 inches from heat. Broil for 1-3 minutes until marshmallows puff and turn golden brown, watching closely to avoid burning. Alternatively, use a kitchen torch to toast marshmallows.
  10. Let the slab cool on a wire rack for at least 15 minutes before slicing.
  11. Cut into large squares or rectangles and serve.

Notes

Do not overmix the batter to avoid cakey brownies. Watch marshmallows carefully while broiling to prevent burning. Use room temperature eggs for better texture. Let brownies cool before slicing to avoid sticky marshmallow mess. Warm knife under hot water and dry before cutting for clean slices. Crush graham crackers by hand or with rolling pin for rustic texture. Optional: add chocolate chips or chunks for extra melty pockets.
