I was shopping for another food product, and Marshmellow fluff popped up under recommendations. I was so excited to try it in my favorite recipes, but then I froze—staring at my pantry and fridge, asking myself, “Where do I put this? Does Marshmallow Fluff need to be refrigerated?”
You’re not alone if you’ve ever been unsure how to store this sweet, gooey treat. Let’s clear up the mystery together.
Does Marshmallow Fluff Need To Be Refrigerated
No, Marshmallow Fluff doesn’t need refrigeration. It’s designed to stay fresh at room temperature, making it perfect for your pantry. However, storing it in the fridge is an option if you live in a hot climate or want to keep it fresh longer. Just know that refrigeration can make it firmer and harder to spread.
What is a Marshmallow Fluff
Marshmallow Fluff is a light, gooey spread made from sugar, egg whites, and vanilla. It’s super versatile and can be used in many delicious ways. It’s a sweet treat that brings endless possibilities to your kitchen creations.
The best way to use Marshmallow Fluff
The best way to use Marshmallow Fluff depends on your sweet cravings. Here are some popular ideas:
- Fluffernutter Sandwich: Spread it with peanut butter between two slices of bread for a classic treat.
- S’mores: Skip the campfire and spread Fluff on graham crackers with chocolate.
- Frosting or Filling: Use it to frost cupcakes or fill cakes.
- Hot Chocolate: Swirl it into your mug for a creamy topping.
How should Marshmallow Fluff be stored?
Marshmallow Fluff should be stored at room temperature in a cool, dry place. Keep the lid tightly sealed to prevent it from drying out or getting sticky.
If you want to extend its shelf life, you can refrigerate it, but this isn’t necessary. Refrigeration may make the Fluff firmer, so let it warm up a bit before using it for easy spreading.
Here are some handy tips and tricks for storing Marshmallow Fluff:
- Always close the lid firmly to keep it fresh and prevent drying out.
- Store it in a cool, dry spot away from heat or direct sunlight.
- If you don’t use it often, keep it in the fridge to extend its shelf life.
- Chilled Fluff can harden—let it sit at room temperature or microwave for a few seconds to soften.
- Wipe the jar rim before sealing to avoid sticky messes and make reopening easier.
How long does marshmallow fluff last in the fridge once opened?
Once opened, Marshmallow Fluff can last about 2 to 3 months in the fridge if stored properly. Make sure the lid is tightly sealed to prevent air from getting in, and always use a clean utensil to scoop it out to avoid contamination.
If it becomes too firm, let it sit at room temperature for a few minutes or microwave it for a few seconds to soften.
