Ingredient Notes

Dark Chocolate
Using real dark chocolate instead of only cocoa powder gives the brownies a rich fudgy texture.

Tips For Perfect S’mores Brownies
A few simple baking tips make a huge difference.
Don’t Overbake
The brownies should still look slightly soft in the center when removed from the oven. They continue setting while cooling.
Watch The Broiler Carefully
Marshmallows toast extremely fast. Stay near the oven because they can burn within seconds.
Cool Before Slicing
Let the brownies cool completely before cutting or the layers will fall apart.
Use A Hot Knife
Run your knife under hot water and wipe it clean between slices for sharp clean brownie squares.
How To Make S’mores Brownies
Start by making the graham cracker crust using crushed graham crackers, melted butter, and sugar. Press the mixture firmly into the pan and bake briefly until set.
Next prepare the brownie batter by melting dark chocolate and butter together until smooth. Whisk in sugar, eggs, and vanilla until glossy before folding in flour and cocoa powder.
Pour the brownie batter over the crust and bake until the center is slightly soft but mostly set.
Immediately after baking, top the brownies with mini marshmallows and chocolate chips. Broil for a minute or two until the marshmallows become golden brown and beautifully toasted.
Once cooled, slice into squares and enjoy the gooey layers.
