Ingredients

To create this heavenly Lemon Blueberry Fluff, you’ll need:

8 oz (226g) cream cheese, softened to room temperature
1 cup (240ml) heavy whipping cream
¾ cup (150g) granulated sugar

2 tablespoons fresh lemon juice (approximately 1 medium lemon)
1 tablespoon fresh lemon zest (approximately 1 medium lemon)
1 teaspoon vanilla extract

1 cup (175g) fresh blueberries, plus extra for garnish
1 box (3.4 oz/96g) instant lemon pudding mix
1 cup (240ml) milk, cold

2 cups (60g) mini marshmallows
Optional: 1 sleeve (about 9) graham crackers, crushed for garnish or base

The cream cheese provides a rich, tangy foundation, while the heavy cream whips into a cloud-like texture that gives the fluff its signature lightness. Fresh lemon juice and zest are essential for that authentic citrus punch—bottled juice simply won’t deliver the same bright flavor. Choose plump, fresh blueberries for the best taste and texture in this lemon blueberry dessert.

Pro Tips

Achieve Perfect Texture
The key to creating the ultimate Lemon Blueberry Fluff lies in the proper handling of the cream cheese. Allow it to soften completely at room temperature for at least an hour before beginning. This ensures it will blend smoothly without any lumps that could compromise the fluff’s cloud-like texture. When you beat the cream cheese with sugar, continue until the mixture is light and exceptionally fluffy—this initial aeration sets the foundation for the entire dessert.

Master the Folding Technique
When incorporating the whipped cream into your lemon-cream cheese mixture, use a gentle folding motion rather than stirring. This preserves the air bubbles that create the signature fluffy texture. Use a silicone spatula and cut through the center of the mixture, then sweep around the bottom of the bowl and up the side in a rotating motion. Continue this folding pattern until just combined—overmixing will deflate your creation and result in a denser consistency.

Blueberry Management Strategy
For the most visually stunning and texturally balanced Lemon Blueberry Fluff, reserve a portion of your blueberries for folding in at the very end. Lightly coat these berries in a teaspoon of flour before adding them to prevent them from sinking and bleeding too much color into the mixture. For the remaining berries, lightly mash them before incorporating to create beautiful purple swirls throughout the dessert. This dual approach ensures both aesthetic appeal and the occasional burst of whole blueberry in every bite.

Instructions

Step 1: Prepare the Lemon Base
In a large mixing bowl, beat the softened cream cheese and granulated sugar together until smooth and fluffy, about 2-3 minutes. The mixture should look light and airy with no lumps remaining. Add the lemon juice, lemon zest, and vanilla extract, then beat again until completely incorporated. The fresh citrus will immediately infuse the mixture with that distinctive sunny aroma that makes this Lemon Blueberry Fluff so irresistible.

Step 2: Create the Pudding Layer
In a separate medium bowl, whisk together the instant lemon pudding mix and cold milk until it begins to thicken, about 2 minutes. The pudding provides additional lemon flavor while contributing to the dessert’s creamy texture. Let it stand for 5 minutes to set slightly, then fold it gently into your cream cheese mixture until just combined. The mixture will now have a beautiful pale yellow color with streaks of bright lemon zest throughout.

Step 3: Whip the Cream
In another clean bowl, whip the heavy cream until stiff peaks form. This typically takes 3-4 minutes with an electric mixer on medium-high speed. The cream should stand tall when you lift the beaters but still look smooth and glossy, not grainy or separated. This whipped cream will transform your dessert into the cloud-like creation that gives Lemon Blueberry Fluff its name.

Step 4: Combine Components
Using a silicone spatula, gently fold the whipped cream into the lemon mixture in three batches. Focus on preserving as much air as possible by using a light touch and a folding motion rather than stirring. Once the cream is incorporated, add the mini marshmallows and fold them in as well. They add delightful texture and contribute to the fluff’s iconic consistency.

Step 5: Add Blueberries and Chill
Gently fold 3/4 cup of the fresh blueberries into the mixture, being careful not to crush them. Reserve the remaining 1/4 cup for topping. For a marbled effect, you can lightly mash a small portion of the blueberries before adding. Transfer the completed Lemon Blueberry Fluff to a serving bowl or individual dessert dishes, then cover and refrigerate for at least 4 hours or overnight to allow the flavors to meld and the texture to set perfectly.

Step 6: Garnish and Serve
Before serving, top your Lemon Blueberry Fluff with the reserved fresh blueberries, additional lemon zest, and crushed graham crackers if desired. The contrast between the fluffy yellow dessert and the dark blue berries creates a visual treat that’s as appealing to the eye as it is to the palate. Serve chilled for the most refreshing experience.

Variations

Berry Bonanza Version
Transform this Lemon Blueberry Fluff into a mixed berry extravaganza by incorporating a variety of summer fruits. Replace half the blueberries with a combination of fresh raspberries, blackberries, or sliced strawberries. This variation creates a beautiful confetti of color throughout the dessert while introducing additional flavor dimensions. The tartness of raspberries particularly complements the lemon base, while strawberries add a sweet counterpoint that children especially love.

Lemon Blueberry Fluff Pie
Convert this fluffy delight into an impressive dessert pie with minimal extra effort. Prepare a graham cracker crust by combining 1½ cups graham cracker crumbs with 6 tablespoons melted butter and 3 tablespoons sugar. Press this mixture into a 9-inch pie plate and bake at 350°F for 8 minutes, then cool completely. Pour your prepared lemon blueberry mixture into the cooled crust, refrigerate until set, and finish with whipped cream and fresh berries for a more structured presentation that’s perfect for special occasions.

Lighter Option
For a lighter version of this Lemon Blueberry Fluff, substitute Neufchâtel cheese (⅓ less fat) for regular cream cheese and use light whipped topping instead of heavy cream. You can also replace the sugar with a natural sweetener like stevia or monk fruit (adjust quantities according to package instructions). This adaptation reduces calories while maintaining the essential flavor profile and cloud-like texture that makes this dessert so popular.

Storage and Serving

The Lemon Blueberry Fluff will keep beautifully in the refrigerator for up to 3 days when stored in an airtight container. The flavors actually improve after the first 24 hours as they have time to meld together, making this an ideal make-ahead dessert for entertaining. However, for the best texture, consume within 2 days, as the whipped cream component may begin to deflate slightly after this time.

This refreshing treat can be served in various elegant ways. For a casual family dessert, simply spoon it into small glass bowls or mason jars topped with extra blueberries and a sprig of fresh mint. For more formal occasions, layer it parfait-style in clear glasses alternating with crushed graham crackers for an appealing visual effect and textural contrast. It also makes a wonderful filling for crepes or as a topping for pound cake or angel food cake.

For an extra-special presentation, hollow out lemon halves and fill them with the Lemon Blueberry Fluff for individual servings that highlight the citrus theme. Alternatively, serve small scoops in dessert cups with shortbread cookies on the side for a delightful texture combination.

FAQs

Can I use frozen blueberries instead of fresh?
Yes, you can use frozen blueberries, but they should be thawed and drained thoroughly to remove excess moisture. Pat them dry with paper towels before folding them into the Lemon Blueberry Fluff to prevent the mixture from becoming watery and turning an uneven purple color.

Why did my fluff mixture curdle?
Curdling typically occurs when the cream cheese is too cold when mixed. Always ensure your cream cheese is fully softened to room temperature before beginning. Also, adding lemon juice directly to cold dairy products can cause curdling, so it’s important to incorporate it into the cream cheese mixture before adding the whipped cream.

Can I make this dessert dairy-free?
Absolutely! Substitute the cream cheese with dairy-free cream cheese alternative, use coconut cream instead of heavy whipping cream, and choose a plant-based milk for the pudding mix. The Lemon Blueberry Fluff texture will be slightly different but still delicious.

How far in advance can I prepare this for a party?
This dessert can be prepared up to 24 hours in advance for optimal flavor and texture. Add any graham cracker or cookie garnishes just before serving to prevent them from becoming soggy.

Can I freeze leftover Lemon Blueberry Fluff?
While it’s possible to freeze this dessert, the texture may change upon thawing as the whipped components tend to deflate. If you do freeze it, thaw overnight in the refrigerator and consider re-whipping or folding in additional freshly whipped cream before serving.
