The epitome of summer! Bring the campfire indoors with this super simple, but decadent cake. It's incredibly moist, sweet with layers of graham cracker cake, rich chocolate and toasty marshmallows.
Preheat oven to 350°F. Grease a 9-inch square baking pan and line with parchment paper. Set aside.
In a large bowl, beat together with a mixer the butter, brown sugar and sugar. Add eggs, one at a time, continuing to beat. Add in vanilla and beat until combined.
In another bowl, stir together graham cracker crumbs, flour and baking powder. Pour in egg mixture and stir. Pour mixture into greased baking pan. Bake for 35 minutes.
Add the chocolate and heavy cream to a small saucepan. Melt over low heat, stirring constantly. Remove immediately from heat once chocolate melts. Pour over top of the cooled cake.
Preheat oven to broil on low heat. Top chocolate with marshmallows. Broil for 30 seconds to 1 minute. Remove from oven and let cool 15 minutes at room temperature before transferring to the fridge to chill for 30 minutes.
Notes
Keep an eye on the marshmallows because they will go from lightly toasted to burnt in a matter of seconds.
