These delicious bars are made with our favorite s'mores ingredients: graham crackers, milk chocolate, and miniature marshmallows. They're easy to make, and you don't need a campfire!

The buttery crushed graham cracker crust is topped with chocolate bars and mini marshmallows for a delicious oven-baked s'mores treat.

  • 18 graham crackers (crushed, about 3 cups)
  • 1/2 cup all-purpose flour
  • 1/2 teaspoon salt
  • 8 milk chocolate bars (approximately 1 1/2 ounces each)
  • 3 1/2 cups miniature marshmallows

Steps to Make It

  1. Heat oven to 350 F/180 C/Gas 4. Butter a 13x9x2-inch baking pan.

  2. Beat butter and sugar with electric mixer on medium speed until light and fluffy. Beat in egg and vanilla. Stir in crushed graham crackers, flour, and salt.

  4. Arrange chocolate bars, in a single layer, over graham cracker crust mixture in the pan. Sprinkle with marshmallows.

Recipe Variations

  • Sprinkle raisins over the graham cracker layer before the chocolate bars.
