How to Make Key Lime Pie Fruit Dip
Step 1: Mix the Lime Base
In a medium mixing bowl, whisk together the marshmallow fluff, sweetened condensed milk, key lime juice, and lime zest until smooth and fully combined.
Step 2: Whip the Cream
In a large bowl, use a hand mixer or stand mixer to beat the heavy whipping cream until stiff peaks form. This creates the light and fluffy texture that makes the dip irresistible.
Step 3: Fold Everything Together
Gently fold the whipped cream into the key lime mixture. Continue folding until no streaks remain and the mixture is smooth and airy.
Step 4: Chill the Dip
Cover the bowl and refrigerate for at least 1 hour. Chilling allows the flavors to blend together and helps the dip achieve the perfect consistency.
Step 5: Garnish and Serve
Before serving, sprinkle extra lime zest on top for a beautiful presentation and an extra burst of citrus flavor.
