Method
Prep and bake graham cracker base
- Preheat the oven to 350°F and line a 9x13 pan with parchment paper.
- Mix the graham cracker crumbs, sugar, and melted butter, then press firmly into the bottom of the pan; bake for 6 minutes.
Make brownie batter and bake
- Whisk the melted butter and granulated sugar until smooth, then whisk in the eggs and vanilla extract.
- Stir in the unsweetened cocoa powder, all-purpose flour, baking powder, and salt until smooth, then spread the batter over the graham cracker crust.
- Bake at 350°F for 22-25 minutes, until a toothpick comes out with a few moist crumbs.
Broil marshmallows and finish
- Scatter the mini marshmallows over the top in an even layer.
- Broil on HIGH for 1-3 minutes, watching carefully, until golden and bubbly on top.
- Cool for 30 minutes to set, then drizzle the melted chocolate over the surface.
- Cut into 16 squares using a buttered knife.
Notes
Pro tip: press the crust firmly so it bakes into a cohesive golden layer that won’t crumble when you cut. Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days; freeze up to 2 months for best texture. For a gluten-free option, swap in a 1:1 gluten-free all-purpose flour blend for the brownie layer.
