You can freeze the whole loaf or cut it into slices and freeze the individual slices. You can also use this recipe to make muffins and then freeze the muffins. I recommend wrapping the banana bread loaf, slices, or muffins in plastic wrap. Then place them in a large zip-top plastic bag and label them with the date before placing them in the freezer. This banana flax bread will keep well for 3 months in the freezer.
