Common Mistakes to Avoid
Making Frankenstein Halloween Rice Krispie Treats can be fun, but avoiding common mistakes will ensure your treats are a hit.
- Boldly skip the butter: Forgetting to grease your dish can make it difficult to remove the treats. Always butter your casserole dish before pouring in the mixture.
- Boldly rush the melting: Melting the marshmallows too quickly can cause them to burn. Use low to medium heat and stir constantly for a smooth texture.
- Boldly ignore cooling time: Cutting the treats before they cool may result in messy shapes. Allow them to set for at least 30 minutes before slicing.
- Boldly overlook measurements: Using too much or too little cereal can affect the consistency of your treats. Measure carefully to keep that perfect balance.
- Boldly forget decorations: Skipping royal icing eyes or sprinkles makes for less festive treats. Don’t skip these fun details; they bring your Frankenstein treats to life!
