Combine the Greek yogurt, powdered sugar, and vanilla extract in a medium bowl. Stir together until combined.
Next fold in the whipped topping until combined with the yogurt mixture. Enjoy immediately or refrigerate until ready to serve. Serve with an assortment of your favorite fruit.
*If using store-bought whipped topping, like Cool Whip, make sure it's thawed in the refrigerator before mixing with the rest of the ingredients. You can also use a homemade whipped cream.
