- Overheating Marshmallows: Cooking marshmallows too long can lead to a rubbery texture. Melt them slowly over low heat for the best consistency.
- Not Pressing Firmly: If you don’t press the mixture firmly into the dish, the treats will crumble when cut. Make sure to pack them down well.
- Skipping the Setting Time: Cutting the treats before they have set can result in messy shapes. Allow them to cool for at least 30 minutes before slicing.
- Inconsistent Coating: Dipping treats unevenly in candy melts can lead to a patchy appearance. Ensure each treat is fully coated for a uniform look.
