Yes, you can freeze them and I highly recommend it. Once they have cooled, place between sheets of parchment or wax paper in a covered container and pop into the freezer. You can freeze these little zucchini cakes for up to 3 months. To Thaw: Pre heat the oven to 350 degrees. Place the cakes on a parchment lined sheet pan and bake for 10 - 15 minutes until the cakes are thawed and warmed through.
