If you want to place several portions together in one container or freezer bag, it is best to individually wrap them. You can use this method for homemade or store-bought cream cheese frosting.
Decide what sized portions you will need when it is thawed and divide the frosting up into those sized amounts.
Tear off a sheet of plastic wrap big enough to completely cover one portion and lay it flat on the counter
Place your portion of frosting in the middle of the plastic wrap and secure it around the frosting so it is totally enclosed.You can twist each end of plastic wrap to help seal it off and hold it together. Repeat this for each portion.
Place your wrapped portions of frosting into a freezer bag or airtight container.
Seal it up by pressing any air out of the bag and zipping it closed. If you used a container, simply secure the lid on top of it.
Write the date on it and toss it into the freezer.
