In a separate bowl, whisk together the whipped topping, sour cream, and vanilla extract (if using) until smooth and creamy.
Step 4: Toss Everything Together
Pour the creamy dressing over the fruit mixture. Gently fold everything together until evenly coated. Be careful not to crush the delicate fruits.
Step 5: Chill and Serve
Cover the salad and refrigerate for at least 30 minutes to allow the flavors to meld.
Give the salad a quick stir before serving. Enjoy the sweet, tangy goodness!
