This high-protein cottage cheese strawberry mousse started as one of those “let’s see what happens” kitchen experiments, and I’m so glad it worked. It’s light, creamy, fluffy, and feels like a proper dessert, but each serving packs around 15 grams of protein. It’s the kind of recipe that feels indulgent, yet balanced. Easy to make, simple ingredients, and satisfying enough to actually keep you full.
Why This Is My Favorite High-Protein Dessert
I love this recipe for those times when I want something sweet but fresh and light. It’s not a baked dessert, it’s not overly rich, and it never feels like a compromise. Just a spoonable, creamy strawberry cloud that sits somewhere between a mousse and a cheesecake filling, in the best possible way.
Ever since I discovered how powerful cottage cheese can be for boosting protein intake, I’ve been using it in everything. Once blended, it turns completely smooth and almost magical. It becomes this creamy, neutral base that works in so many recipes. I’ve turned it into chocolate mousse, lemon mousse, cheesecake, and even breads. It’s one of those ingredients that surprises you once you see what it can do.
✔ It feels like real dessert, not a “healthy version.” – It’s creamy, fluffy, and indulgent, yet light enough that you don’t feel weighed down after.
✔ It’s genuinely high in protein and actually satisfying. – Thanks to blended cottage cheese, each serving delivers real protein that keeps me full, not hunting for snacks 10 minutes later.
✔ It’s effortless but impressive. Just a blender and a few simple ingredients turn into something smooth, elegant, and spoonable. No baking, no stress.
✔ The texture is unreal. Once blended, cottage cheese becomes silky and airy, creating that mousse-like consistency that feels almost too good for how simple it is.
Ingredient Notes (The Little Things That Matter)
What I love most about this recipe is how short and simple the ingredient list is.
- Cottage Cheese –Full-fat gives the creamiest result and more satisfying texture. If you prefer lower calories, low-fat works too, just blend it really well so it turns completely smooth. Small curd cottage cheese blends the easiest.
- Strawberries – Fresh or frozen both work. If using frozen, thaw them first and drain excess liquid for the best flavor and texture. Swap idea: You can use raspberries or mixed berries, but keep in mind raspberries are more tart.
- Sweetener – This depends on your goal. For low carb, use powdered allulose, monk fruit, or a monk fruit blend. Powdered sweetener blends smoother. For a more natural option, maple syrup or honey work beautifully. Start small and adjust after blending, because strawberry sweetness varies.
- Vanilla Extract – Adds warmth and dessert vibes without overpowering the strawberries.
- Salt – Just a pinch, but it makes everything taste brighter.
- Gelatin – This gives the mousse its structure. Bloom it properly in cold water before dissolving for the smoothest texture. Vegetarian option: Agar agar can work, but it sets firmer and needs to be heated properly.
- Protein Powder – Vanilla works best here. If using a very sweet protein powder, reduce the added sweetener. Tip: Whey blends smoother than some plant-based proteins.
Now Comes the Fun Part: Let’s Make the Mousse
This is where everything comes together in minutes.
Bloom the gelatin.
In a small bowl, sprinkle the gelatin powder over the cold water. Let it sit for about 5 minutes until it looks spongy. This step is important: don’t rush it.
Melt gently.
Microwave the bloomed gelatin for 10–15 seconds until fully liquid. Do not let it boil. Set it aside to cool slightly while you blend the rest.
Blend the cottage cheese first.
Add cottage cheese to a high-speed blender or food processor and blend for 60–90 seconds until completely smooth and creamy. This step makes or breaks the texture.
Add strawberries and flavor.
Add strawberries, sweetener, vanilla extract, and a pinch of salt. Blend again until light, fluffy, and fully combined. Taste and adjust sweetness now.
Add gelatin slowly.
With the blender running on low, slowly pour in the melted gelatin. Blend just 10–15 seconds, enough to combine, not overmix.
Chill.
Spoon the mousse into jars or bowls. Refrigerate for at least 30 minutes, or up to 1 hour if you want a firmer, cheesecake-style texture.
Serve chilled.
Grab a spoon and enjoy straight from the fridge.
Texture & Success Tips
- Not smooth enough? Blend the cottage cheese longer before adding anything else.
- Too soft? Chill longer, gelatin firms up as it cools.
- Too thick? Next time add a splash of strawberry juice or milk before blending.
- Extra fluffy feel? Let it chill fully, then give it a gentle stir before serving.
Storing Ideas
- Fridge-friendly dessert: Store the mousse in covered jars or airtight containers in the fridge for up to 7 days.
- Gets better with time: After a few hours of chilling, the texture becomes even creamier and more set.
- Perfect for prep: Make it ahead and grab a jar whenever you want something sweet and satisfying.
- No freezing needed: Freezing changes the texture, so this one’s best enjoyed straight from the fridge.
- Quick refresh tip: If it firms up too much, give it a quick stir before serving.

When is the 1scoop vanilla protein added to recipe???
The protein powder gets added right before blending the strawberry mixture. I usually add it together with the strawberries, sweetener, vanilla, and salt so everything blends evenly and stays light and creamy.

I really appreciate you taking the time to share this. One of my goals with this recipe was creating a high-protein dessert that still feels light and refreshing instead of heavy, and cottage cheese works surprisingly well for that creamy mousse texture. I’m so happy you enjoyed it and plan to make it again.
It’s so simple , delicious and refreshing that I’ll definitely be making it often in my kitchen. Thank you for sharing this wonderful recipe!
That makes perfect sense for this recipe. As the peppers, onions, and beef cook down, they release enough liquid that some people prefer making the casserole without broth for a thicker texture. Thank you so much for trying the recipe and sharing your experience.
