- 1 (10oz) bag mini marshmallows

How to Make Frankenstein Halloween Rice Krispie Treats
These come together in just a few fun steps. Here’s how we do it:
Step 1: Make the Rice Krispie Base
- Butter a 9″ x 13″ casserole dish and set aside.
- In a large pot over low-medium heat, melt the butter.
- Add the mini marshmallows and stir until completely smooth and gooey.
- Pour in the rice krispie cereal and stir with a spatula until evenly coated.
- Press the mixture into the casserole dish and flatten the top. Let it set for 30 minutes.
Pro tip: Lightly grease your hands or spatula so the mixture doesn’t stick when pressing it into the dish.
Step 2: Cut & Shape Your Frankensteins
- Once cooled, remove the rice krispies from the dish.
- Use a sharp knife to cut into rectangles—make them different sizes for variety.
And Step 3: Dip in Green & Add Hair
- Melt the green candy melts in a bowl over a pot of simmering water.
- If the melts are too thick, stir in a teaspoon of vegetable shortening.
- Dip the tops of the rice krispie rectangles into the green chocolate.
- Immediately dip into black jimmies sprinkles for Frankenstein’s hair.
Step 4: Add Eyes & Pipe Stitches
- Stick on two royal icing eyes before the candy coating sets.
- Melt the black candy melts in the microwave using 10–15 second bursts.
- Pour into a piping bag and pipe on stitches or spooky smiles.
Let everything set fully before handling or packaging.
Tips for Perfect Frankenstein Treats
- Use fresh marshmallows for the best texture.
- Grease everything – your spatula, hands, and knife for easy shaping.
- Customize the faces with different candy decorations.
- Store in an airtight container at room temp for up to 4 days.
- Want them on sticks? Insert lollipop sticks before dipping.
