Instructions

1 Preheat the oven to 350°F (175°C). Line an 8x8-inch metal baking pan with foil, leaving an overhang on two sides for lifting the brownies out, and lightly grease the foil.
2 In a large bowl, whisk the cocoa powder into the warm melted butter until smooth. Whisk in the sugar, then the eggs one at a time, then the vanilla and salt, until the batter is glossy and thick, about 1 minute.
3 Fold in the gluten-free flour blend with a spatula until no dry streaks remain, then fold in 1/2 cup of the chocolate chips. Spread the batter evenly in the pan.
4 Bake for 20-25 minutes, until the edges are set and a toothpick in the center comes out with moist crumbs. Scatter the marshmallows and graham cracker crumbs evenly over the hot brownies and return the pan to the oven for 3-4 minutes, until the marshmallows puff and soften. Then switch to the broiler and broil on the middle rack for 30-60 seconds, until the marshmallows are golden, watching closely; they go from golden to burnt in seconds.
5 Cool the brownies completely in the pan on a wire rack, at least 1 1/2 hours. Melt the remaining 1/2 cup of chocolate chips in 20-second microwave bursts, stirring between each, and drizzle it over the top. Let the chocolate set for about 10 minutes, then lift the brownies out and cut them with a lightly oiled knife, wiping it between cuts.

Tips & Notes

Standard graham crackers contain gluten, and marshmallow ingredients vary by brand, so choose graham-style crackers and marshmallows that are each labeled gluten-free.
For clean squares, chill the cooled brownies for 30 minutes before cutting. The marshmallow layer stays sticky at room temperature, so oil and wipe the knife between cuts.
Store the brownies in a single layer in an airtight container at room temperature for up to 3 days. The toasted marshmallow turns softer and chewier after the first day.
