Does fudge last in refrigerator?

Quick Answer

Fudge can last 2-3 weeks in the refrigerator if stored properly in an airtight container. The refrigerator slows down the crystallization process, helping fudge stay creamy and preventing a sugar bloom from forming. Wrap fudge tightly and place in the main body of the fridge, not the door.

How Long Does Fudge Last in the Fridge?

Properly stored fudge will keep for 2-3 weeks in the refrigerator. The cold temperature of the fridge slows down the rate of sugar crystallization, helping the fudge retain its soft, creamy texture. It also prevents a sugar bloom, which is when condensation causes sugar crystals to form on the surface.

Here are some tips for maximizing fudge freshness in the fridge:

  • Store fudge in an airtight container, plastic wrap, or zip top bag. Air exposure will cause it to dry out.
  • Wrap the fudge very tightly with no air gaps. This prevents condensation from forming.
  • Place fudge in the main body of the fridge, not the door. The temperature varies too much in the door.
  • Keep the fridge between 35-40°F. Higher temps speed up crystallization.
  • Don’t store fudge near foods with strong odors. It can absorb fridge odors.

Properly stored, fudge can last 2-3 weeks in the refrigerator before quality declines. Signs fudge has gone bad include drying out, sugar crystallization, weeping oil, and mold growth.

Why Fudge Lasts Longer Refrigerated

Refrigeration helps fudge maintain quality and extend shelf life for a few key reasons:

Slows Sugar Crystallization

The process of sugar crystallization is temperature-dependent – the warmer fudge is, the faster crystallization occurs. Refrigerating fudge slows down this process to prolong its shelf life.

Retains Moisture

Cool fridge temperatures retain moisture to keep fudge soft and creamy. Without refrigeration, fudge quickly loses moisture and stiffens.

Prevents Sugar Bloom

When there is humidity and moisture in the air, sugar can recrystallize on the fudge’s surface, creating an unappetizing whitish coating called sugar bloom. Keeping fudge refrigerated minimizes this issue.

Slows Mold Growth

The cool environment of the refrigerator slows down mold growth. Tight wrapping prevents air exposure that could also introduce mold spores.

Minimizes Odor Absorption

Fudge is porous and can easily soak up odors from other foods. Refrigeration limits odor transfer since food smells are less volatile at lower temperatures.

Signs Fudge Has Gone Bad

Here are the most common signs that fudge has gone bad and should be discarded:

Drying Out

Fudge that is drying out will become stiff, crumbly, and dry rather than being creamy and soft. Discard dried out fudge.

Sugar Crystallization

Extensive crystallization will give fudge a grainy, crunchy texture and whitish appearance. Heavily crystallized fudge should be tossed.

Weeping Oil

The oil may begin to separate and leak from the fudge. Weeping oil indicates spoilage.

Mold Growth

Look for fuzzy spots of black, green, or white mold. Moldy fudge must be discarded.

Unusual Odor/Flavor

Fudge that smells or tastes off should not be eaten. Trust your senses.

Does Refrigeration Affect Fudge Quality?

Refrigerating fudge does lead to some cumulative quality changes over time. However, proper storage helps slow down these unwanted effects.

Here is how refrigeration impacts fudge:

Texture Changes

The texture slowly stiffens and becomes less smooth. This is due to increased crystallization of sugar molecules.

Mutes Flavor

Cooler temperatures mute volatile flavors like chocolate and spices. The flavor dulls over time.

Odor Absorption

Strong fridge odors can be absorbed by fudge, changing the flavor. Use an airtight container.


Moisture condensing on the fudge leads to sugar bloom. Tight wrapping prevents this issue.

Dries Out

Exposure to cool, dry refrigerator air removes moisture from fudge over time. Use an airtight container.

So while refrigeration extends shelf life, some decline in quality does occur. Fudge is best consumed within 1 week for peak texture and flavor.

How to Store Fudge in the Refrigerator

Use these tips for properly storing fudge in the refrigerator:

Use An Airtight Container

The best way to store fudge is in an airtight plastic or glass container. This prevents moisture loss, odor absorption, and air exposure.

Wrap Tightly in Plastic Wrap

If you don’t have a container, wrap fudge tightly in plastic wrap or place in a zip top bag with all air squeezed out.

Place On Center Shelf

Store fudge on a middle shelf, away from the cooling vents, high humidity of produce drawers, and variable temperatures of door shelves.

Divide Into Smaller Portions

Cut fudge into smaller pieces or slices before storage. This minimizes air exposure when removing portions to eat.

Keep Away From Strong Odors

Store fudge away from foods with strong odors like cheese, onions, and fish which can transfer flavors.

How Long Can You Store Fudge In the Freezer?

Properly stored in the freezer, fudge will keep for 4-6 months before quality degrades. To maximize freezer shelf life:

  • Wrap fudge tightly in plastic wrap or place in airtight freezer bag. Remove air.
  • Stack layers with parchment paper to prevent sticking if not using container.
  • Store at 0°F or below. Use freezer thermometer to monitor temperature.
  • Avoid temperature fluctuations from opening freezer frequently.
  • Place fudge on middle freezer shelves for most consistent temps.

The freezer halts crystallization and moisture loss entirely, but may impart a drier texture over time as some moisture still escapes.

Thawing Fudge

Thaw frozen fudge gradually in the refrigerator overnight. Microwave defrosting is not recommended as it can make fudge too soft. Let come to room temp before eating for best flavor and texture.

Can You Keep Fudge At Room Temperature?

It’s best not to store fudge at room temperature for more than 1-2 days. Without refrigeration:

  • The texture quickly dries out and becomes grainy.
  • mold growth is more likely in humid conditions.
  • Oil separation occurs more quickly.
  • Sugar bloom manifests faster.
  • The flavor dulls and fudge loses its decadence.

For food safety, room temperature fudge should be thrown out after 2 days. However, the declining quality makes it ideal to enjoy fudge within 1-2 days.

If giving fudge as a gift, include a note that recommends refrigerating and enjoying within 1 week for best results.

Does Fudge Need To Be Refrigerated After Opening?

Yes, fudge should always be refrigerated after opening. Once the packaging is opened and fudge is exposed to air, quality and freshness decline rapidly if left at room temperature:

  • Dries out within 12-24 hours
  • Absorbs odors and stale fridge smells
  • Crystallization occurs very quickly
  • Oil can begin separating out
  • Risk of mold is increased

After opening fudge, transfer it to an airtight container or bag with as much air removed as possible. Refrigerate within 30 minutes of opening for best results. Consume within 1 week.

Proper post-opening storage gives you the longest window to enjoy fudge at optimal quality.

How To Revive Old Hard Fudge

If your fudge has dried out, try one of these tricks to revive it:

Microwave in 10 Second Bursts

Gently microwave the fudge in 10 second intervals, checking after each. Stop when slightly warm. This may relax the sugar crystals.

Steam Over Boiling Water

Place fudge in bowl suspended over gently simmering water. Steam for 1-2 minutes to soften.

Add Condensed Milk

Mix in a tablespoon or two of condensed milk. The added moisture should improve fudge texture.

Blend with Milk

For buttery, nut, or chocolate fudge, blend in a food processor with 2-3 tablespoons milk until smooth.

Enjoy Over Vanilla Ice Cream

Top slightly melted vanilla ice cream with crumbled dried out fudge for an impromptu fudge sauce.

Common Fudge Storage Mistakes

Avoid these common fudge storage errors:

Storing at Room Temperature

Leaving fudge out quickly makes it dry and crumbly. Refrigerate within 30 minutes of making.

Not Using Airtight Container

Exposed to air, fudge will stale rapidly. Store in an airtight sealed container.

Placing In Refrigerator Door

The temperature fluctuates too widely in the door. Keep fudge on a middle shelf.

Storing Too Long

Eat within 1 week for best texture and flavor. Toss if hardened, dried, or moldy.

Not Cutting Into Portions

Each time you open the container, moisture escapes. Cut fudge into smaller pieces for minimal air exposure.

Leaving At Room Temperature After Opening

Once opened, refrigerate fudge within 30 minutes. Leaving it out overnight ruins the texture.

Tips for Making Long Lasting Fudge

Use these tips to make fudge with a longer shelf life:

Cook to Proper Temperature

Cooking fudge to the right temp helps set structure. Boil to 236-240°F depending on type.

Avoid Underbeating

Underbeating after cooking can result in a grainy texture faster. Beat for full time recommended in recipe.

Add Dried Fruit/Nuts At End

Stirring in dried fruits or nuts early can interrupt fudge setting up properly. Fold in gently at the very end.

Use Fresh Dairy

Make fudge with fresh cream and butter. Older dairy causes faster spoilage.

Avoid Using Soft Margarine

Regular butter helps fudge firm up better than soft spreads. Use real butter if possible.

Replace Egg Whites for Whole Eggs

Egg whites give fudge structure without adding moisture that reduces shelf life.


Properly stored fudge can keep for 2-3 weeks in the refrigerator and 4-6 months in the freezer. For best results, store fudge in an airtight container in the main fridge compartment – not the door. Keep the fridge between 35-40°F. Letting fudge come to room temperature before serving helps bring out its flavor and texture. While refrigeration extends shelf life, some decline in moisture and flavor will occur over time. For peak quality, fudge is best enjoyed within 1 week of making.
