Add cream cheese, marshmallow fluff, and lemon extract to a large mixing bowl. Beat with a hand-held mixer on medium speed until smooth (about 2 to 3 minutes).
Gently fold in frozen whipped topping.
Transfer the mixture to a serving dish and serve with fresh fruit.
Notes
Make sure to scrape the mixing bowl when beating the cream cheese and marshmallow fluff.
If you aren’t serving this dip right away, cover it and store it in the fridge until ready to serve.
