What should be used instead of soft serve mix for a sugar-free shake?

Using heavy whipping cream as a substitute for soft serve mix in a sugar-free shake is a viable choice due to its rich texture and higher fat content, which can help mimic the creaminess that soft serve typically provides. Heavy whipping cream also has minimal carbohydrates and sugars compared to other dairy options, making it suitable for a sugar-free diet. When blended into a shake, it can create a velvety consistency and a satisfying mouthfeel without the added sugar found in many soft serve mixes. This makes it an excellent option for those seeking a sugar-free alternative while still delivering on flavor and texture.
