How to Make Frankenstein Halloween Rice Krispie Treats

Common Mistakes to Avoid

When making Frankenstein Halloween Rice Krispie Treats, it’s easy to overlook a few key steps. Here are some common mistakes to avoid:

Skipping the butter: Not greasing the casserole dish can lead to sticky treats that are hard to remove. Always butter your dish well before adding the mixture.
Not melting marshmallows completely: Failing to melt the marshmallows smoothly can result in unevenly mixed treats. Stir continuously over low heat until fully melted and smooth.
Forgetting to press firmly: If you don’t press down the mixture firmly into the dish, the treats will crumble when cut. Use a spatula or your hands (with butter) to pack it tightly.
Overheating candy melts: Melting the candy melts too quickly can cause them to seize up. Use a double boiler or microwave in short bursts, stirring frequently.
Rushing cooling time: Cutting into the treats before they set can make them fall apart. Allow at least 30 minutes for cooling before slicing.
