What Is Lemon Fluff?

Lemon Fluff is an old-fashioned no-bake dessert made with lemon pudding or gelatin, whipped topping (or real whipped cream), and sometimes cream cheese or sweetened condensed milk. It can be layered over a graham cracker crust, angel food cake cubes, or served as a scoopable “fluff salad.”

This version features a light lemon cake base, topped with a cool, whipped lemon-cream cheese layer, then finished with fluffy whipped topping and lemon zest.

How to Make Lemon Fluff Dessert

Step 1: Bake the Cake Base

Preheat oven to 350°F (175°C). Prepare the lemon cake mix according to package directions. Bake in a 9×13-inch pan and let cool completely.

💡 Shortcut Option: Use store-bought pound cake or sponge cake cubes if you want a no-bake base.

Step 2: Make the Lemon Fluff Layer

In a large bowl, beat the softened cream cheese until smooth and fluffy. Slowly add the sweetened condensed milk, followed by lemon juice and zest. Mix until fully incorporated.

Fold in the Cool Whip gently with a spatula to maintain the light, airy texture.

Step 3: Assemble

Spread the lemon fluff mixture evenly over the cooled cake. Then top with additional Cool Whip or whipped cream.

Chill in the refrigerator for at least 4 hours (or overnight) to allow the flavors to set and meld.

Step 4: Garnish and Serve

Just before serving, garnish with lemon zest, lemon curls, or thin lemon slices.

Cut into squares or scoop into bowls—and enjoy that first blissful bite!
