Gooey dessert bars that capture the nostalgic flavors of campfire s’mores graham crackers, chocolate, and marshmallows in a chewy, buttery, and perfectly sweet form.


Ingredients

Scale

1/2 cup (113 g) unsalted butter, softened
3/4 cup (150 g) packed light or dark brown sugar
1 large egg, room temperature
1 tsp vanilla extract
1 cup (125 g) all-purpose flour
1 cup (120 g) graham cracker crumbs (about 8 crackers)

1/4 tsp salt
1 cup (180 g) semi-sweet chocolate chips
1 heaping cup marshmallow creme (Fluff or homemade)
