Step-by-Step Guide to Make Frankenstein Halloween Rice Krispie Treats

1. Melt the Butter and Marshmallows

In a large pot over medium heat, melt 3 tablespoons of butter. Add the marshmallows and stir until fully melted and smooth.

2. Tint the Mixture

Remove from heat and stir in the green food coloring until you reach a Frankenstein-like shade of green.

3. Mix in Cereal

Quickly add the Rice Krispies and stir until completely coated with the marshmallow mixture.

4. Press and Cool

Press the mixture evenly into a buttered or parchment-lined 9×13-inch baking dish. Let cool for about 20 minutes.

5. Cut and Shape

Once set, cut the treats into rectangles to form Frankenstein’s “head.”

6. Decorate

• Dip the top third of each rectangle into melted chocolate to create the “hair.”
• Place two candy eyes just below the chocolate.
• Use black gel icing to draw a stitched mouth and eyebrows.
• Add mini marshmallow or pretzel “bolts” to each side.
