Common Mistakes to Avoid

- Boldly melting the marshmallows: Don’t rush this step. If you melt the marshmallows too quickly, they can become grainy. Use low-medium heat and stir constantly for a smooth mixture.
- Boldly skipping the buttering step: Forgetting to butter the dish can make your treats stick. Always grease your casserole dish with butter to ensure easy removal.
- Boldly over-mixing the cereal: Mixing too vigorously can crush the cereal and lead to dense treats. Gently fold in the cereal until just coated for a light texture.
- Boldly rushing the cooling time: Cutting the treats too soon leads to messy shapes. Allow them to cool fully for at least 30 minutes before slicing.
- Boldly ignoring candy melt consistency: If your candy melts are too thick, they won’t coat well. Add a teaspoon of vegetable shortening if needed to achieve a smoother texture.
