How Do You Thicken Heavy Whipping Cream Frosting?
To thicken heavy whipping cream frosting, you can add powdered sugar or cornstarch. Start by adding a tablespoon of either ingredient at a time until you reach the desired consistency. Be careful not to add too much as it can alter the taste and texture of the frosting. You can also chill the frosting in the refrigerator for a few minutes before using to help it set.
