Ingredients

  • 6 tbsp unsalted butter plus more for the pan
  • 1 bag 10 1/2 oz mini marshmallows
  • 1/4 c unsweetened Dutch-process cocoa
  • 6 c crisp rice cereal
  • 2 oz bittersweet chocolate melted
  • Crushed peanuts optional

Instructions

  • Butter an 8-inch square baking pan.
  • Line the pan with parchment paper, allowing the paper to extend up the two short sides and overhang slightly on both ends.
  • Lightly butter the parchment paper and set the pan aside.
  • In a large saucepan over low heat, melt the butter completely.
  • Add the mini marshmallows and the Dutch-process cocoa.
  • Stir frequently for about 6 minutes, or until the marshmallows are fully melted and the mixture is smooth.
  • Remove the saucepan from the heat.
  • Add the crisp rice cereal and stir until the cereal is evenly coated with the chocolate marshmallow mixture.
  • Transfer the mixture to the prepared pan.
  • Using a piece of wax paper, press the mixture gently and evenly into the pan.
  • If desired, sprinkle the top with crushed peanuts.
  • Drizzle the melted bittersweet chocolate over the surface.
  • Let the treats cool to room temperature.
  • Once fully set, remove from the pan and cut into 16 bars.

Notes

To make these Double Chocolate Marshmallow Treats gluten free, use a certified gluten-free crisp rice cereal, since many standard crisp rice cereals contain malt or other gluten ingredients. Also confirm that the mini marshmallows, cocoa powder, bittersweet chocolate, and any optional toppings such as crushed peanuts are labeled gluten free, as brands and manufacturing practices can vary. For anyone with celiac disease or severe gluten sensitivity, use clean pans, parchment, spatulas, saucepans, and cutting tools to avoid cross-contact.
