This High-Protein Lemon Blueberry Mousse is light, fluffy, refreshing, and packed with bright citrus flavor. Greek yogurt provides a creamy, protein-rich base, while sugar-free lemon pudding mix helps create a thick, scoopable texture without added sugar. Fresh blueberries add bursts of sweetness and color, and whipped cream gives the mousse its soft, airy finish.
The recipe makes a generous batch of about six cups, so it is perfect for meal prep, family desserts, parties, or portioning into individual jars. You can also add vanilla protein powder for an extra protein boost or swap the heavy cream for a lighter whipped topping.

Ingredients
- 3 cups plain nonfat Greek yogurt
- 2 boxes sugar-free lemon instant pudding mix, about 1 ounce each
- 1 cup cold heavy whipping cream
- 1/3 cup fresh lemon juice
- 1 tablespoon fresh lemon zest
- 1 1/2 cups fresh blueberries
- Extra blueberries for topping
- 2 scoops vanilla or unflavored protein powder, optional
Ingredient Notes
Greek yogurt: Thick Greek yogurt creates the best base and contributes most of the natural protein. Nonfat yogurt keeps the dessert lighter, while full-fat yogurt creates a richer mousse.
Lemon pudding mix: Use instant sugar-free pudding mix rather than cook-and-serve pudding. The dry mix thickens the yogurt as it hydrates.
Heavy whipping cream: Whipping the cream separately is what creates the light mousse-like texture. It should be very cold before whipping.
Protein powder: Vanilla protein powder works particularly well with lemon. Different powders thicken differently, so add a tablespoon of yogurt if the mixture becomes overly stiff.
Blueberries: Fresh berries hold their shape best. Frozen berries can work, but thaw and drain them first to prevent excess moisture.
How to Make High-Protein Lemon Blueberry Mousse
- Place the Greek yogurt in a large mixing bowl.
- Add the dry lemon pudding mix, lemon juice, lemon zest, and optional protein powder.
- Beat with an electric hand mixer until completely smooth and well combined.
- Place the cold heavy whipping cream in a separate chilled mixing bowl.
- Beat until stiff peaks form. Avoid overbeating, or the cream can become grainy.
- Add about half of the whipped cream to the lemon yogurt mixture.
- Fold gently with a silicone spatula until mostly incorporated.
- Add the remaining whipped cream.
- Fold gently until no large white streaks remain.
- Add the blueberries.
- Fold them in carefully so they stay intact.
- Spoon the mousse into one large container or divide it between individual serving jars.
- Top with additional blueberries.
- Cover and refrigerate for at least 30 minutes before serving.
How to Get the Fluffiest Texture
Keep the heavy cream very cold and, if possible, chill the bowl and beaters before whipping. Cold cream traps air more efficiently and forms stronger peaks.
Once the whipped cream goes into the yogurt base, fold rather than stir. Aggressive stirring deflates the air bubbles and produces a denser dessert.
Add the whipped cream in two stages. The first portion lightens the yogurt mixture, making it easier to fold in the remaining cream without losing volume.
Chilling for at least 30 minutes gives the pudding mix time to hydrate and helps the mousse become thicker and more scoopable.
How to Adjust the Consistency
If the mousse becomes too thick, fold in one or two tablespoons of Greek yogurt or cold milk.
If it seems too soft, refrigerate it for another 30 to 60 minutes before changing the recipe. The pudding mixture continues thickening as it chills.
If you add protein powder, the mousse may become significantly thicker depending on the brand. Start with one scoop, then add the second only if the texture remains creamy.
Lighter Whipped Topping Variation
For a lighter and easier variation, replace the cup of heavy whipping cream with an 8-ounce container of thawed sugar-free or reduced-sugar whipped topping.
There is no need to whip it separately. Fold the topping directly into the lemon yogurt mixture in two additions.
The finished mousse will still be light and airy, though the flavor and nutrition will differ from the heavy-cream version.
Easy Flavor Variations
For vanilla berry mousse, replace the lemon pudding mix with sugar-free vanilla pudding and use strawberries, raspberries, or mixed berries.
For lemon raspberry mousse, replace the blueberries with fresh raspberries and add extra lemon zest.
For peach vanilla mousse, use vanilla pudding and fold in well-drained diced peaches.
For lemon cheesecake mousse, beat four ounces of softened cream cheese into the yogurt base before folding in the whipped cream.
For a stronger citrus flavor, add additional lemon zest rather than excessive lemon juice, which can thin the mixture.
Serving Suggestions
Spoon the mousse into small dessert glasses and garnish with blueberries, lemon zest, or a small swirl of whipped cream.
For extra crunch, top individual servings with chopped almonds, pecans, or a small amount of low-sugar granola.
The mousse can also be layered with berries in clear jars for a simple make-ahead parfait.
Protein and Sugar Note
Even when made with sugar-free pudding mix, this dessert is not necessarily completely sugar-free because Greek yogurt, blueberries, and some protein powders contain naturally occurring carbohydrates or sugars.
The final protein content will also depend on the yogurt and protein powder brands used. For accurate nutrition information, total the values from your ingredient labels and divide by the number of servings.
Portioning for Meal Prep
This recipe makes approximately six cups of mousse. Dividing it into twelve half-cup containers gives you convenient individual portions.
Keep the containers covered in the refrigerator and add any crunchy toppings only when serving so they stay crisp.
For smaller portions, use four-ounce containers and adjust the number of servings accordingly.
Storage
Store the mousse in airtight containers in the refrigerator for up to three to four days for the best texture and freshness.
The blueberries may release a small amount of juice during storage, so fold the mousse gently before serving if needed.
Freezing is not recommended for the best texture because Greek yogurt and whipped cream can separate after thawing.
