Portion it out into the amounts you will want to cook once defrosted.
Spoon or pour your portions into individual freezer bags or airtight containers.note: if using a container, try to size it so that there is only 1 - 2 inches of space between the batter and the lid. This will help prevent freezer burn or texture degradation
Seal the package up by pressing all the air from the bag and zipping it shut. Or, simply pressing the lid onto the top of your container.
Label the outside of the package with the date and lay it flat in the freezer.
