Ingredients

  • 3 tablespoons unsalted butter
  • 1 cup dark chocolate chips
  • ¼ cup dark cocoa powder
  • 9 cups mini marshmallows, divided
  • 6 cups Rice Krispies cereal

Optional Toppings

  • ½ cup dark chocolate chips
  • ½ teaspoon vegetable oil
  • mini chocolate chips or chocolate sprinkles
  • flaky sea salt

Instructions

  • Line a 9x13 or 9x9 pan with parchment paper or aluminum foil with an overhang for easy removal.
  • Melt butter, 1 cup chocolate chips, and cocoa powder over low heat in a large pot or Dutch oven. The mixture will be thick.
    Add 7 cups marshmallows and stir until melted.
    Remove from heat. Use a sturdy wooden spoon or spatula to stir in the rice krispies and 2 more cups of mini marshmallows until combined.
  • Pour or spoon the mixture into prepared pan. Use a buttered spatula or buttered fingers to spread the chocolate rice krispie mixture into the pan. Don't press too firmly or the rice krispie bars can become hard. Cool the bars in the pan.
  • Add toppings. Melt ½ cup chocolate chips and ½ teaspoon oil in the microwave for 30 seconds or until smooth. Drizzle melted chocolate on top of the chocolate rice krispie bars. Sprinkle mini chocolate chips or chocolate sprinkles while the chocolate is still wet. Add flaky sea salt, if desired.

Notes

  • Gently melt the chocolate mixture and marshmallow mixture over low heat. Too high of heat can cook the marshmallows and make the mixture hard when cooled. 
  • For thicker bars, press the mixture into a 9x9 square pan. 
  • Be careful not to press the chocolate rice krispie mixture into the pan too firmly or the bars can become compact and hard.
