Yes I have frozen whole milk. I pour 2 cups into a food saver bag that I have sitting in a Tupperware container. Pop into freezer for 24 hours then seal bags with Food Saver machine. Milk is stable frozen for 4 months. Once thawed it is good for 4 days. Works great for me. You can freeze a whole gallon after you remove about a cup of milk to allow for expansion. Just remember it is only good for 4 days once thawed.
Thanks for the tips!
