Ensure your whipped topping is fully thawed before mixing, as cold, icy bits can alter the texture of your final frozen strawberry fluff recipe. Pat your diced strawberries dry with a paper towel if they are particularly juicy to prevent excess water from forming ice crystals in the freezer. Fold the ingredients using a large rubber spatula with a circular motion to avoid deflating the whipped topping during the preparation phase. Let your frozen strawberry fluff recipe sit at room temperature for five minutes before serving to ensure the perfect scoopable consistency.
