Can a pop tart be refrigerated?

Pop tarts can be refrigerated, although it is not recommended by the manufacturer. Refrigeration can make the pastry dough of the pop tart hard and crumbly, and the filling may also become firmer and less flavorful. Additionally, the frosting on the pop tart may become grainy or separate from the pastry. If you do choose to refrigerate pop tarts, it is best to consume them within a few days to avoid these issues.
