Yes, you can freeze this cake! First, allow the cake to cool completely. Don't add any frosting or icing. Then wrap the cake in saran or press and seal wrap. Write the contents and the date on the press and seal. Then wrap it again in aluminum foil, and transfer it to a freezer-safe container. It will keep in the freezer for up to 3 months. When ready to serve, remove from the freezer, and transfer to the refrigerator to thaw for at least 8 hours. Do not remove the cake from the wrapping. Allow it to thaw while still in its wrap. After 8 hours it will be ready to dust with powdered sugar, or icing, and serve! For more tips on how to freeze cakes visit Sally's Baking Addiction's post, How to Freeze Cakes.
