  • 6 tbsp (85g) unsalted butter, melted

For the Brownies:

  • 3/4 cup (150g) light brown sugar, packed
  • 4 large eggs
  • 1 tbsp vanilla extract
  • 1 cup (125g) all-purpose flour
  • 3/4 cup (65g) unsweetened cocoa powder
  • 1/2 tsp salt
  • 1/2 tsp baking powder
  • 1 cup (170g) semi-sweet chocolate chips

For the Marshmallow Topping:

  • 3 cups (150g) mini marshmallows
  • 1/2 cup (85g) chopped milk chocolate or chocolate chips (optional for garnish)

Instructions

Step 1: Make the Graham Cracker Crust

  1. Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
  2. In a bowl, mix graham cracker crumbs, sugar, and melted butter until combined.
  3. Press the mixture evenly into the bottom of the prepared pan.
  4. Bake for 8-10 minutes, then set aside while making the brownie batter.

Step 2: Make the Brownies

  1. In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth.
  2. Add eggs and vanilla: Beat in eggs one at a time, followed by vanilla extract.
  3. In a separate bowl, whisk together flour, cocoa powder, salt, and baking powder.
  4. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
  5. Fold in chocolate chips (if using).
  6. Pour batter over the baked graham cracker crust and spread evenly.

Step 3: Bake & Add Marshmallows

  1. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  2. Remove from oven and immediately sprinkle mini marshmallows evenly over the brownies.
  3. Return to oven and broil on low for 1-2 minutes until marshmallows are golden brown. Watch closely! They can burn quickly.
  4. (Optional) Sprinkle with chopped chocolate for extra gooeyness.

Step 4: Cool & Serve

  1. Let the brownies cool for 15-20 minutes before slicing.
  2. Cut into squares and enjoy!

Notes

  • Broiling Tips: If you don’t have a broiler, you can use a kitchen torch to toast the marshmallows.
  • Make It Extra Crunchy: Add a layer of crushed graham crackers on top of the marshmallows before broiling.
  • Storage: Store in an airtight container at room temperature for 2-3 days or refrigerate for up to 5 days.
  • Freezing: Freeze uncut brownies for up to 3 months. Thaw before serving.
