These S'mores brownies contain everything you love about a S'mores dessert in an easier to eat brownie form. Perfectly toasted marshmallows followed by a layer of fudgy chocolate brownie, all on top of a crunchy graham cracker crust.
Preheat the oven to 350°F (177°C). Line an 8-inch square baking pan with parchment paper, leaving some overhang on the sides for easy removal later.
Line the bottom with a layer of graham crackers. Cut if needed to make some of them fit. You should need about 15-16 crackers. Add the remaining graham crackers to a food processor and pulse them until they become fine crumbs.
Add chocolate chips to a large microwave-safe bowl. Heat in the microwave at full power in 30 second increments, stirring in between with a spatula, until the chocolate is completely smooth and melted.
Add in the condensed milk and mix until the batter is uniform in color.
Stir in the crushed graham crackers until they are evenly combined.
Pour batter into the prepared baking pan, on top of the layer of graham crackers. Use a spatula to even out the surface if needed. Add mini marshmallows on top, covering the surface.
Bake for about 30 minutes until marshmallows are golden brown on the surface and a toothpick inserted into the brownies comes out mostly clean. Let brownies cool before cutting. Because of how fudgy the brownies are and how sticky the marshmallows are, I recommend using a large sharp knife and heating the blade by dipping it into hot water before cutting (wiping the blade clean after each cut).
Notes
You can also use dark chocolate chips if you don't want the brownies to be as sweet. However if you use dark chocolate the brownies won't be as chewy. They will still be fudgy.
Graham crackers are usually in a sheet with each sheet containing 4 individual crackers. This recipe uses 32 individual crackers.
You will need 1 (14 oz) can of sweetened full fat condensed milk. 14 oz refers to weight, not volume.
We recommend eating the brownies warm so that the marshmallow layer is still melted.
The brownies are quite rich so we recommend cutting them into 16 pieces (or smaller if you want). We cut them into 12 pieces in the photos. The estimated nutrition assumes the brownies are cut into 16 pieces.
