Storage Suggestions
If you manage to have any leftover Bars + Brownies, these can store well if prepped appropriately. Once they have cooled completely, here is how you can store it:
- Counter: Store bars and brownies in an airtight container at room temperature for up to 4 days. If your kitchen is particularly warm, consider refrigerating instead to prevent them from getting too soft or melty.
- Refrigerator: Place in an airtight container and refrigerate for up to 1 week. Let them come to room temperature before serving for the best texture and flavor.
- Freezer: To freeze, make sure bars and brownies are completely cooled and unfrosted. Wrap tightly in plastic wrap (or Press & Seal) and then place in a freezer-safe bag or container. For easier portioning, wrap individual squares before freezing. Don’t forget to label with the date. They’ll stay fresh in the freezer for up to 3 months.
