Using a fork, mix the peanut butter and the vanilla yogurt.
Once these two ingredients are well mixed, add the whipped topping. Mix until just combined.
Cut up fruit for dipping. I recommend apple slices and banana slices.
Notes
My kids enjoyed cut up apples and bananas with this fruit dip. If you cut up your fruit a few minutes ahead of time, soak the fruit in Sprite for 5 minutes to prevent it from browning.Refrigerate in an air tight container for up to 3 days. Since this is so quick and easy to make, I don't freeze it, I only make what will be used within a couple of days.
