Ingredients

Scale
  • 1 cup (125 g) all-purpose flour
  • 1/3 cup (35 g) unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder (optional)
  • 3/4 cup (150 g) granulated sugar
  • 1/2 cup (100 g) packed brown sugar
  • 1/2 cup (115 g) unsalted butter, melted
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 3/4 cup (135 g) semi-sweet chocolate chips
  • 1 cup (50 g) crushed graham crackers
  • 1 1/2 cups (90 g) mini marshmallows
  • Optional: chopped toasted nuts (pecans or walnuts)
  • Optional: flaked sea salt for sprinkling
  • Optional: peanut butter chips or white chocolate chips

Instructions

  1. Preheat your oven to 350°F (175°C). Tear off a large sheet of heavy-duty aluminum foil about 12×12 inches and fold the edges up slightly to create a shallow tray. Place the foil tray on a baking sheet for stability.
  2. In a large bowl, whisk together the flour, cocoa powder, salt, and baking powder (if using) to evenly distribute.
  3. In another bowl, whisk the granulated sugar, brown sugar, and melted butter until smooth.
  4. Beat in the eggs one at a time into the butter-sugar mixture, then stir in the vanilla extract until the batter is glossy and thick.
  5. Gradually fold the dry ingredients into the wet ingredients with a spatula until just combined. Avoid overmixing.
  6. Fold in the semi-sweet chocolate chips gently.
  7. Spread the batter evenly into the foil tray and smooth the top. Sprinkle the crushed graham crackers evenly over the batter, then top with mini marshmallows.
  8. Bake for 25-30 minutes or until marshmallows are golden brown and edges are set but the center jiggles slightly when nudged. Start checking at 23 minutes to avoid burning.
  9. Remove from oven and let cool in the foil for at least 15 minutes to firm up.
  10. Lift the brownies out using the foil edges, slice into squares with a sharp knife, and serve warm or at room temperature.

Notes

Use heavy-duty foil or double-layer regular foil to prevent leaks. Tent with foil if marshmallows brown too fast. Let brownies rest 15 minutes before slicing for clean cuts. Variations include peanut butter swirl, gluten-free flour and graham crackers, vegan substitutions, and adding spices like cayenne or cinnamon.
