Ingredients

Scale

Main Ingredients

  • Nonstick baking spray
  • 4 tablespoons unsalted butter
  • 10 ounces mini marshmallows (5-1/2 cups)
  • Pinch kosher salt
  • Green food coloring
  • 5 cups Rice Krispies cereal

Decorations

  • 8 ounces semisweet chocolate chips
  • ¼ cup chocolate sprinkles
  • 20 candy eyeballs
  • 20 Reese’s Minis Unwrapped
  • Black writing gel
  • Red writing gel (optional)


Instructions

  1. Prepare Pan: Spray the bottom and sides of a 13 x 9-inch pan with nonstick baking spray to prevent sticking.
  2. Melt Butter: In a large pot, melt 4 tablespoons of unsalted butter over medium-low heat until fully melted.
  3. Add Marshmallows and Color: Add 10 ounces of mini marshmallows, a pinch of kosher salt, and green food coloring. Stir continuously until the mixture is fully combined, smooth, and bright green; add more food coloring if needed.
  4. Mix Cereal: Remove the pot from heat. Add 5 cups of Rice Krispies cereal and stir until the cereal is evenly coated with the green marshmallow mixture.
  5. Press Mixture into Pan: Transfer the mixture into the prepared pan. Use a piece of parchment paper or greased hands to press the mixture evenly toward the bottom of the pan. Let it stand at room temperature for 15 minutes to set.
  6. Cut Treats: Turn the set mixture out onto a cutting board. Cut the rectangle lengthwise in half, then cut each half into 5 pieces crosswise, making 10 treats total.
  7. Melt Chocolate: Place 8 ounces of semisweet chocolate chips into a microwave-safe glass measuring cup or bowl. Microwave in 30-second intervals, stirring between intervals, until the chocolate is smooth and fully melted.
  8. Dip and Decorate: Dip one end of each Rice Krispies treat into the melted chocolate. Place the dipped treats on parchment paper and immediately sprinkle with ¼ cup chocolate sprinkles.
  9. Add Candy Decorations: Use the remaining melted chocolate to attach 20 candy eyeballs and 20 unwrapped Reese’s Minis as Frankenstein’s neck bolts on the treats.
  10. Draw Details: Use black writing gel to add mouths and stitches. Optionally, use red writing gel to add a bit of “blood” for an extra spooky effect.

Notes

  • Use parchment paper or lightly grease your hands when pressing the mixture to prevent sticking.
  • Adjust green food coloring gradually to achieve a bright, vibrant color without overpowering flavor.
  • If you don’t have candy eyeballs, you can substitute with small round candies or draw eyes with writing gel.
  • To melt chocolate smoothly, avoid overheating by stirring frequently and microwaving in short bursts.
  • These treats can be stored in an airtight container at room temperature for up to 3 days.
  • For a dairy-free version, substitute butter with a vegan margarine and use dairy-free chocolate chips.
