Store the peanut butter cups in an airtight container in the refrigerator for up to 10 days. If you plan to keep them longer, freeze them. Place wax paper between layers to stop them from sticking. In the freezer, they last for up to 3 months.
To thaw, move them from the freezer to the refrigerator for 30 to 60 minutes, or let them sit at room temperature for 10 to 15 minutes. Do not leave them a long time at room temperature if your kitchen is warm, as the chocolate can soften and melt.
