How to Store Peanut Butter Blondies

Store: Keep leftover blondies in an airtight container at room temperature for up to five days.

Freeze: Wrap bars individually in plastic wrap, then place them in a freezer-safe container or bag. They freeze well for longer storage.

To thaw: Let frozen blondies come to room temperature, uncovered, so they retain their texture without becoming soggy.
