S’mores Crack is a gooey, addictive dessert bar that combines the classic flavors of s’mores with a toffee-like caramel base. Layers of graham crackers topped with a buttery brown sugar toffee, melted semi-sweet chocolate, and toasted mini marshmallows create an irresistible treat perfect for parties or a sweet snack.

Ingredients

Scale

Base

  • 10 full-size graham crackers

Toffee Layer

  • 1 cup (2 sticks) salted butter
  • 1 cup packed light brown sugar

Toppings

  • 2 cups semi-sweet chocolate chips
  • 2 cups mini marshmallows

Instructions

  1. Prepare the Baking Sheet: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking sheet with parchment paper or aluminum foil, making sure to cover the sides for easy cleanup.
  2. Arrange Graham Crackers: Place the graham crackers in a single layer on the baking sheet, breaking them as needed so they cover the entire bottom evenly.
  3. Make the Toffee Layer: In a medium saucepan over medium heat, melt together the butter and brown sugar, stirring constantly. Bring the mixture to a rolling boil and continue cooking for 3-4 minutes until it thickens slightly and turns a rich caramel color.
  4. Pour and Bake Toffee: Pour the hot toffee mixture evenly over the graham crackers, using a spatula to spread it to cover all crackers. Place the baking sheet in the preheated oven and bake for 5-7 minutes until the toffee bubbles.
  5. Add Chocolate and Marshmallows: Remove the baking sheet from the oven and immediately sprinkle the chocolate chips evenly on top. Let them sit for 1-2 minutes to melt, then spread the melted chocolate into an even layer with a spatula. Sprinkle mini marshmallows evenly over the chocolate.
  6. Toast the Marshmallows: Set your oven to broil. Place the baking sheet back in the oven for 1-2 minutes, watching closely to toast the marshmallows until golden brown. Be careful not to burn them.
  7. Cool and Serve: Remove from the oven and allow the S’mores Crack to cool completely in the pan before cutting and serving.

Notes

  • Use salted butter for balanced flavor; if using unsalted, add a pinch of salt.
  • Watch the marshmallows carefully during broiling to prevent burning.
  • For easier cleanup, use parchment paper to line the baking sheet.
  • Store leftovers in an airtight container at room temperature for up to 3 days.
  • You can substitute semi-sweet chocolate chips with milk or dark chocolate chips based on your preference.
