Ingredients

  • 6 cups crispy rice cereal
  • 4 cups mini marshmallows
  • 3 Tbsp unsalted butter
  • Green food coloring
  • 4–6 oz melting chocolate or chocolate squares (for “hair”)
  • Candy eyes
  • Black gel icing (for mouths/scars)

Add a pinch of salt and ½ tsp vanilla for extra flavor.

Directions

  1. Melt: In a large pot over low heat, melt butter. Stir in marshmallows until smooth; tint with green food coloring.
  2. Mix: Remove from heat and fold in the cereal until evenly coated.
  3. Press & set: Press into a greased or parchment-lined 9×13-inch pan. Cool until firm, 20–30 minutes.
  4. Cut: Lift out and cut into rectangles.
  5. Decorate: Dip or spread the top edge with melted chocolate for hair. Add candy eyes; pipe mouths and scars with black gel.

Party tip: Insert mini pretzel “neck bolts” on the sides!
