I have a sleeve so this might be different, but I make sugar free ice cream all the time. I use half and half, almond milk, oikos triple zero Greek Yougert, and eggs for the base. Then I use stevia and a variety of flavorings. I add 3 scoops of unflavored Protein powder. It has 22 grams of protein per serving. My favorites are Peanut Butter where I add PB2 powder, and chocolate almond using crushed almonds and coco powder.
This way I get ice cream and meet my protein goals.
