Servings: 20

Prep time: 20 minutes

Cook time: 10 minutes

Total time: 30 minutes


  • 16 tbsp. (2 sticks) Unsalted Butter

  • 2 10-oz bags Mini Marshmallows
  • 1 tsp. Vanilla
  • ¼ tsp. Fine Sea Salt
  • 8 cups Rice Krispies
  • 1 ½ cups Powdered Sugar
  • 1 bar Tony Chocolonely Milk Chocolate, melted
  • 1 bar Tony Chocolonely 70% Dark Chocolate, melted
  • Gold Sprinkles
  • Chocolate Sprinkles
  • Mini Candy Eyes


  1. To Make the Chocolate Rice Krispies: Line a 9x13” baking pan with parchment paper that overhangs “sleeves” for easy removal later. Set aside 1 cup marshmallows as reserve. 
  2. In a large pot over medium high heat, add 12 tablespoons of butter to melt. Once melted, stir until the butter has browned, about 1-2 minutes. The butter should smell nutty and look like a toasty brown color.
  3. Reduce heat to medium. Stir in the vanilla and salt.
  4. Add the marshmallows (except the reserved 1 cup) to the large pot. Stir until the marshmallows have melted.
  5. Remove 1 cup melted marshmallow for the spider webs later.
  6. Add in the rice krispies. Stir until well combined. 
  7. Add in the reserved 1 cup marshmallows and mix until just combined.
  8. Transfer into the prepared baking pan and press into the pan with slightly wet fingers.
  9. Reserve 1/3 cup of the melted dark chocolate for the chocolate buttercream.
  10. Drizzle the remaining melted chocolates over the rice krispies. Lightly swirl together with a knife.
  11. Place in the freezer for 10 minutes, until the chocolate is hardened.
  12. To Make the Spider Webs: If needed, heat up the reserved 1 cup marshmallow fluff over low heat. Use your fingers to spread the marshmallows across the hardened chocolate to mimic “spider webs.”
  13.  To Make the Chocolate Spiders: Add the remaining 4 tbsp. butter and 1/3 cup chocolate to the bowl of a stand mixer. Beat until smooth, about 1-2 minutes. Add the powdered sugar, and 1 tablespoon heavy cream if frosting is too thick.
  14. Add more powdered sugar if frosting is too thin. Pipe two dots to mimic a spider’s head and body, then 4 legs on each side. Decorate the legs with the sprinkles and the head with the candy eyes.
  15. Slice into individual rice krispies to be enjoyed!
