Ingredients

  • 1.5 cup graham cracker crumbs finely crushed
  • 6 tbsp unsalted butter melted
  • 2 tbsp granulated sugar
  • 1 cup unsalted butter softened
  • 1.5 cup granulated sugar
  • 4 large eggs room temperature
  • 1 tsp vanilla extract
  • 1 cup all-purpose flour
  • 0.75 cup unsweetened cocoa powder sifted
  • 0.5 tsp salt
  • 2 cup mini marshmallows
  • 0.5 cup semi-sweet chocolate chips

Notes

Storage: Keep in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. For make-ahead, prepare and bake without marshmallow topping; store covered at room temperature up to 1 day, then add marshmallows and chocolate chips and bake as directed before serving. Variations: Substitute milk chocolate chips or add chopped nuts to the batter. For a firmer marshmallow layer, briefly broil the topping after baking (watch closely to prevent burning).
