Yes, you can freeze this cake with or without the frosting. You can either freeze the entire cake or freeze slices. I would recommend you slice your cake into portion sizes before freezing. This way you can take out a portion at a time whenever you're ready to eat a piece. To prevent the slices from sticking together during freezing use a sheet of baking paper in between each slice. This way you’ll be able to get a perfect slice out every time.
