How long do king cake last?

King cake is a traditional dessert served during the Carnival season leading up to Mardi Gras. It’s a circular shaped cake often decorated in the Mardi Gras colors of purple, green, and gold. King cakes are packed with flavor from cinnamon, nutmeg, and vanilla. They often contain fillings like cream cheese, fruit preserves, or pecans. However, with all these delicious ingredients, many wonder just how long a king cake will stay fresh and tasty.

How Long Does King Cake Last at Room Temperature?

An uncut, whole king cake that has not been sliced into can be left at room temperature for 2-3 days. The dense dough helps prevent early staling. As long as the cake is tightly wrapped in plastic wrap or foil, it should retain optimal freshness for a couple days when stored on the counter or another room temperature area. Any slices that have already been cut from the cake will stale faster and should be eaten within 1-2 days when left out.

How Long Does King Cake Last Refrigerated?

Refrigerating a whole, uncut king cake will extend its shelf life. When kept refrigerated in a sealed container or bag, a king cake will stay fresh for 5-7 days. This gives you plenty of time to slowly enjoy slices without having to freeze the cake. For optimal freshness, be sure to keep the cake well sealed so it doesn’t absorb fridge odors. Sliced king cake should be refrigerated and consumed within 3-4 days.

How to Store King Cake for Maximum Freshness

To get the most days out of your king cake, follow these storage tips:

  • Store whole, uncut cakes at room temperature up to 2-3 days.
  • Wrap tightly in plastic wrap or aluminum foil.
  • Refrigerate whole cakes up to 5-7 days for extended freshness.
  • Place in a sealed container or bag before refrigerating.
  • Refrigerate any sliced pieces and eat within 3-4 days.
  • Avoid storing king cake in the freezer as this can dry it out.
  • If freezing, thaw overnight in the fridge before serving.

How to Tell if King Cake Has Gone Bad

No one wants to bite into a stale king cake. Here are some signs that your king cake has past its prime and should be discarded:

  • Dried out, cracked appearance
  • Hard, crumbly texture
  • Mold growth
  • Off odors
  • Loss of rich cinnamon aroma
  • Unappealing colors

As long as your king cake retains a pleasant appearance, aroma, and texture, it should be safe to eat. But when in doubt, remember the old saying “When in doubt, throw it out.” Don’t risk getting sick from a king cake that has overstayed its welcome.

Ways to Use Stale King Cake

  • King cake pancakes – Incorporate crumbled cake into pancake batter.

How Long Does King Cake Last In the Fridge?

A whole king cake that hasn’t been cut into will last 5-7 days when properly stored in the refrigerator. It’s important to place the cake in an airtight container or plastic bag before refrigerating so it doesn’t pick up odors from other foods. Any slices cut from the cake stale faster and should be eaten within 3-4 days when refrigerated.

Can You Freeze King Cake?

King cake can be frozen but it may suffer some loss of quality. The high moisture content means ice crystals can form during freezing which damages the tender cake texture. It also increases the chances of the colorful sugar topping becoming cracked or discolored.

If freezing king cake, place in an airtight freezer bag and press out excess air. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before serving. Reheat briefly in microwave or conventional oven to restore texture and flavor.

How to Maintain Freshness When Storing King Cake

Follow these tips for keeping king cake tasting great during storage:

  • Store in an airtight container or plastic wrap/foil for room temperature storage.
  • Avoid plastic bags which can trap condensation.
  • Place in a sealed container or bag in the fridge.
  • Keep away from foods with strong odors.
  • If freezing, use an airtight freezer bag.
  • Thaw overnight in the fridge before serving frozen king cake.

Common Mistakes When Storing King Cake

It’s easy to make mistakes that shorten the shelf life of king cake. Avoid these common storage slip-ups:

  • Not wrapping well in plastic wrap or foil which leads to premature staling.
  • Thinking room temperature storage will last longer than 2-3 days.
  • Assuming refrigeration isn’t needed within 5-7 days.
  • Leaving in the original bakery box instead of sealing in an airtight container.
  • Storing next to strong smelling foods like onions or fish.
  • Letting it thaw on the counter instead of overnight in the fridge.

How Long Can King Cake Sit Out?

While it’s tempting to leave a king cake out to enjoy for several days, this isn’t recommended for food safety reasons. An uncut cake should only sit out at room temperature for 2-3 days maximum. Any slices that have been cut from the cake should be eaten within 1-2 days when left out. After this time, pathogenic bacteria could grow and pose a risk if consumed.

Tips for Serving King Cake Hot or Warm

While king cake is typically served at room temperature, you can heat it up if desired. Here are some serving tips:

  • Microwave 5-10 seconds to slightly warm a slice.
  • Warm in a 250°F oven 5 minutes if cake seems very stale.
  • Slice and toast pieces in the oven or toaster oven until hot.
  • Bake a whole king cake at 300°F for 10 minutes to serve warm.
  • Wrap slices in foil and reheat in a 300°F oven.

Avoid overheating as this can dry out the cake. Heat just until warm, about 80-90°F internal temperature.


With proper storage methods, it’s possible to enjoy king cake for up to a week before it goes stale. Whole, uncut cakes last 2-3 days at room temp and up to a week refrigerated. Any sliced pieces will stale faster. Freezing can extend the shelf life but may impact texture and flavor. Follow these tips to keep your king cake fresh and delicious.
