How to Store Leftovers
Keep your leftovers in an airtight container. Store it in the fridge for three days. The marshmallows will get softer over time. I do not recommend freezing this dessert. It is best served very cold right from the refrigerator. Give it a quick stir before serving again.

- Use a rubber spatula for the folding steps.
- Let it chill for the full hour minimum.
Ways to Switch It Up

- Add crushed graham crackers on top for crunch.
- Try lime pudding for a tropical twist.
Common Questions
Can I use frozen blueberries?
Yes, you can use frozen berries. Make sure to thaw and drain them well. This prevents the fluff from turning purple.
