Muffins in general freeze beautifully and these Coconut Flour Banana Bread muffins are no exception. They can be stored in the freezer for up to 3 months. Freeze them separately on a sheet pan, then toss into a ziplock bag. Or just transfer them to a freezer safe container and freeze. They can also be refrigerated for the first 3 days. If you don't consume them in 3 days, they're better off in the freezer.
