How much whipped cream should be added to a cream slush?

In the context of preparing a cream slush, the ideal choice is to not add any whipped cream. A cream slush typically relies on a mixture of creamy and frozen ingredients blended together to achieve a smooth texture and refreshing taste. The creaminess of the slush itself derives from the ingredients like ice cream, milk, or cream included in the base recipe. Adding whipped cream could interfere with the intended texture and balance of flavors in the slush, potentially making it overly rich or altering its consistency.

While whipped cream can enhance certain desserts or beverages, it is not standard for cream slushes, which are meant to maintain a specific, light, and fluffy texture. The other options suggest varying amounts of whipped cream that would not align with the traditional preparation of a cream slush, as they would introduce an unnecessary additional layer to what is already a creamy drink.
