Expiration & Storage Tips
When does Peanut Butter Cake expire?
A nondairy store-bought Peanut Butter Cake generally lasts for about 1 to 2 days at room temperature if covered with a cake keeper or aluminum foil, and up to a week when refrigerated. An opened cake also has a refrigerated shelf life of about 7 days. If the cake contains dairy products, it needs to be refrigerated at all times and consumed within 4 to 5 days. If frozen in an airtight container tightly, the cake can last up to 2 to 3 months and still taste fresh.
How do you tell if Peanut Butter Cake is bad?
Over time, changes in smell, taste, and texture will indicate that the Peanut Butter Cake has become stale or has molded. The cake may have a slightly sour smell, an off taste, or appear drier than usual. Any signs of mold, such as green, blue, or white spots, is a clear indication that the cake has spoiled and should be discarded immediately.
Tips for storing Peanut Butter Cake to extend shelf life
• Store the cake in a cool, dry place on your countertop if it's to be consumed within a day or two. Wrap it well with plastic wrap or keep in a cake keeper.
• For longer storage, refrigerate the cake in an airtight container or tightly wrapped in aluminum foil.
• To freeze the cake, let it cool completely first. Wrap individual slices in plastic wrap and then in aluminum foil or in an airtight container. Label it with the current date before freezing.
• When defrosting the cake, do so slowly in the refrigerator (usually overnight) to prevent it from growing too soggy or becoming overly moist.
