Lol, this sounds much more complex than my icecream making. (Though mine is more icemilk than anything because I dislike high-fat icecreams and favor high-ice icecreams) I have a chest freezer which gets quite cold, I use that instead of any kind of appliance. Procedure:
- take 1 large food-safe tupperware
- fill halfway with chocolate milk, whole milk, almond milk, or soy milk as desired, plus sugar and vanilla for the kinds that aren't sweet
- add flavorings, such as banana slices and nilla wafers, or oreos, or marshmallow fluff/almond pieces/chocolate chips/coconut. Add enough so the container is about 9/10s full, stirred well
- Put it in the chest freezer, stir it every half hour until too hard to stir
- Eat! ^_^
