Can you just freeze the already made shakes you can buy without the pb (powder peanut butter) or do you have to use it. I have the premier protein shake strawberry and cream and was wanting to make like an ice cream out of just the shake like you made it above by blendering it in my blender until whipped and freezing it and than blendering it again and put back in the freezer until is like ice cream
