These Frankenstein Rice Crispy Treats are a fun, no-bake Halloween snack featuring gooey marshmallow rice crispy bars decorated with green food coloring, chocolate hair, and candy eyes. Perfect for parties, school events, or spooky movie nights, they’re allergy-friendly and easy to customize.

Ingredients

Scale
  • 1/4 cup (56g) unsalted butter
  • 10 oz (284g) mini marshmallows
  • 6 cups (150g) rice crispy cereal
  • 1/4 teaspoon green gel food coloring (or 1–2 teaspoons liquid food coloring)
  • 1/2 teaspoon vanilla extract (optional)
  • 1/2 cup (85g) semi-sweet chocolate chips
  • 1 tube black decorating gel or icing
  • 24 candy eyes

Instructions

  1. Line a 9×13-inch baking pan with parchment paper or lightly coat with nonstick spray, leaving an overhang for easy removal.
  2. In a large pot over medium-low heat, melt the butter, swirling occasionally to prevent browning (about 1-2 minutes).
  3. Add the mini marshmallows and stir constantly until melted and smooth (about 3-5 minutes).
  4. Remove from heat. Add green food coloring and vanilla extract (if using), stirring until the color is vibrant and even.
  5. Pour in the rice crispy cereal and stir quickly and gently until all cereal is coated and no white spots remain.
  6. Scrape the mixture into the prepared pan. Use a buttered spatula or wax paper to press it down evenly to about 1-inch thickness. Do not press too hard.
  7. Let the treats set at room temperature for 30-45 minutes, or refrigerate for 15 minutes until firm and not sticky.
  8. Lift the slab out using parchment handles and cut into rectangles (about 2×3 inches) for Frankenstein faces.
  9. In a microwave-safe bowl, melt chocolate chips in 20-second bursts, stirring between each, until smooth. Let cool slightly.
  10. Dip or spread melted chocolate onto the top third of each rectangle for hair. Press two candy eyes below the chocolate hair. Use black decorating gel or icing to draw a mouth, stitches, and bolts.
  11. Let the decorated treats set until the chocolate is firm (about 15 minutes at room temperature or 5 minutes in the fridge). Serve and enjoy!

Notes

For gluten-free treats, use certified gluten-free rice crispy cereal and marshmallows. For dairy-free/vegan, use plant-based butter and vegan marshmallows. Press mixture gently for chewy bars. Let chocolate set fully before stacking. Decorate with any candies you have on hand—creativity encouraged! Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
