This crunchy and sweet S’mores Graham cracker toffee recipe is made with graham crackers at the bottom, a buttery toffee layer on top, then melted chocolate, and then finished with garnishes of mini marshmallows and crushed graham crackers.
Place 8 Graham crackers on top of the foil in 2 rows to create a rectangle.
Fold the foil up to the edges of the rectangle and create a makeshift box with the foil.
In a small sauce pan, melt the butter over medium heat. Add brown sugar and salt to the melted butter. Stir the mixture frequently and let it simmer for 5 minutes.
Immediately pour the toffee mixture over the prepared crackers and spread it as evenly as possible with an offset spatula.
Place the baking pan into the oven middle rack and bake for 5 minutes.
Meanwhile, break the last Graham cracker into pieces and put them in a ziplock bag. Pound it with a rolling pin to create smaller crumbles.
Remove the baking pan from the oven and immediately sprinkle chocolate wafers on top of the hot toffee.
Wait a minute or two for the chocolate to melt and spread it in an even layer with an offset spatula.
Sprinkle with mini marshmallows and Graham cracker crumbles.
Refrigerate to harden completely before peeling off the foil and breaking into smaller pieces.
