Description

These Halloween Rice Krispies Treats are fun, festive, and perfect for a spooky celebration. Shaped like Frankenstein’s Monster, these bright green, chewy treats are coated with melted chocolate, decorated with candy eyeballs, and finished with playful icing details for a creepy-cute effect.


Ingredients

Scale

Main Ingredients

  • 4 tablespoons unsalted butter
  • 10 ounces mini marshmallows (5-1/2 cups)
  • Pinch kosher salt
  • Green food coloring (enough to achieve bright green color)
  • 5 cups Rice Krispies cereal

Decoration

  • 8 ounces semisweet chocolate chips
  • 1/4 cup chocolate sprinkles
  • 20 candy eyeballs
  • 20 Reese’s Minis unwrapped
  • Black writing gel
  • Red writing gel (optional)
  • Nonstick baking spray (for pan)


Instructions

  1. Prepare the pan: Spray the bottom and sides of a 13 x 9-inch pan with nonstick baking spray to prevent sticking.
  2. Melt butter and marshmallows: In a large pot over medium-low heat, melt the butter. Add the mini marshmallows, a pinch of kosher salt, and green food coloring. Stir continuously until the mixture is fully combined, smooth, and a bright green color, adding more food coloring if needed.
  3. Mix with cereal: Remove the pot from heat. Add the Rice Krispies cereal and stir gently until all the cereal is evenly coated with the green marshmallow mixture.
  4. Press mixture into pan: Transfer the mixture into the prepared pan. Use a piece of parchment paper or greased hands to firmly press the mixture evenly into the pan’s bottom. Let it stand at room temperature for 15 minutes to set.
  5. Cut the treats: Turn the set mixture out onto a cutting board. Cut the rectangle in half lengthwise, then cut each half into 5 pieces crosswise, making 10 pieces total.
  6. Melt chocolate: Place semisweet chocolate chips in a microwave-safe glass measuring cup or bowl. Microwave in 30-second intervals, stirring between each, until the chocolate is smooth and fully melted.
  7. Dip and decorate: Dip one end of each treat into the melted chocolate, then place on parchment paper. Immediately sprinkle chocolate with chocolate sprinkles.
  8. Attach features: Use the remaining melted chocolate to attach candy eyeballs and Reese’s Minis as neck bolts onto each treat.
  9. Add finishing details: Use black writing gel to draw mouths and stitches on the treats. Optionally, add a touch of red writing gel to simulate blood for extra spooky effect.

Notes

  • Use greased hands or parchment paper to press the mixture to prevent sticking.
  • Adjust green food coloring to your preferred shade for the marshmallow mixture.
  • If melted chocolate becomes too thick, microwave for a few seconds more to thin it out.
  • Store treats in an airtight container at room temperature for up to 3 days.
  • Red writing gel is optional but adds a fun blood-like detail to the Frankenstein treats.
