Since these cookie bars don’t contain anything that needs to be refrigerated, you can easily store them on the counter. The best way to maintain their freshness is to keep them in an airtight container. Or, you can place them in a ziplock bag.
Can You Freeze Them?
Yes, you can! In fact, this is a great way to store big batches that you plan to give to friends and family. Allow your bars to cool completely.
