Common Mistakes to Avoid

- Skipping the Butter: Not using enough butter can lead to a mixture that sticks together poorly. Make sure to measure accurately and fully melt the butter for the best consistency.
- Overheating the Marshmallows: Heating marshmallows too long can cause them to become tough. Heat them gently and only until they are completely melted and smooth.
- Inadequate Pressing: If you don’t press the mixture firmly into the dish, your treats may crumble. Use a spatula to ensure an even layer and well-packed treats.
- Ignoring Cooling Time: Cutting the treats before they’ve cooled can result in messy shapes. Allow them to set for at least 30 minutes before slicing.
- Not Using Parchment Paper: If you skip lining your dish, cleanup can be a hassle. Always use parchment paper for easy removal of your treats from the dish.
