Storage & Shelf Life
Room Temperature
Homemade fudge stays fresh for 1–2 weeks at room temperature when stored in an airtight container
Refrigeration
When refrigerated properly in an airtight container (or wrapped securely), it can maintain quality for 2–3 weeks—especially helpful in warmer or more humid climates
Freezing
For longer storage, you can freeze the fudge tightly wrapped in parchment or wax paper plus foil, then place it in a freezer-safe container. Properly stored, it keeps well for up to 3 months. Thaw it gradually—ideally first in the fridge, then at room temperature—to preserve its texture
Avoiding Dryness or Odor
Always keep fudge in an airtight container to prevent drying out or picking up fridge odors. Wrapping pieces individually in parchment or wax paper adds extra protection
FAQs
1. How long can I keep fudge at room temperature?
About 1–2 weeks in a cool, dry place, stored in an airtight container
2. Will storing fudge in the fridge make it too firm?
Yes, refrigeration makes it firmer. Let it sit at room temperature briefly before enjoying if you prefer it softer
3. How should I freeze fudge?
Wrap pieces tightly in wax or parchment paper, then foil or plastic wrap, and place in a sealed freezer bag or container. It will last up to 3 months
4. Can I refreeze thawed fudge?
It’s better not to refreeze once thawed, as texture and quality may degrade
5. What if I notice dryness or discoloration?
Dry or crumbly texture, odd smells, or white spots may signal spoilage or sugar crystallization—it’s safest to discard in that case.
Conclusion
This Marshmallow Swirl Fudge is an indulgent, creamy dessert that looks as good as it tastes. With proper storage—room temp, fridge, or freezer—you can enjoy its rich, chocolatey goodness for days or even months. I can’t wait for you to try it and savor every square!
