How Long Do Key Lime Bars Last?
Keep your citrus treats fresh and flavorful in the pantry.
Key lime bars stay fresh in a pantry for about 2–3 weeks if stored in an airtight container.
Key lime bars are a tropical delight, blending the tart punch of key limes with a sweet, buttery base. Because these treats often contain fats like butter or condensed milk, their shelf life depends heavily on how well they are sealed against air and moisture. When kept in a cool, dry pantry, they maintain their texture and flavor for several weeks. However, if you notice any signs of staleness or unusual odors, it is best to check them closely before serving.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
