This high-protein chocolate mousse is two ingredients: 300 grams of low-fat skyr and one scoop of chocolate protein powder.

Whisk them together for a minute and you get a thick, creamy chocolate mousse with about 50 grams of protein in the bowl.
It’s my go-to snack after a workout, and what I make at night when I want something chocolatey that still fits my day. No cooking, no blender, no waiting, and nothing to count except two ingredients.
Why You’ll Love This Protein Mousse
- 50 grams of protein. 300 g of skyr brings 30 g of protein and one scoop of chocolate protein adds about 20 g more. That’s as much protein as a large chicken breast, in a dessert.
- 2 ingredients, 2 minutes. One bowl, one whisk. It’s ready before you finish putting your gym bag away.
- Easy to count. Two ingredients, both with the numbers on the label, so tracking calories and macros takes seconds.
- Meal prep friendly. Make a few jars at once and keep them in the fridge for snacks during the week.
- Cheaper than store-bought. A homemade bowl costs about the same as one store-bought protein pudding cup, and most of those have less than half the protein.
Ingredients for Skyr Protein Mousse
- Low-fat skyr. Thick Icelandic-style yogurt with a lot of protein and very little fat. Plain and unsweetened, so the protein powder does the sweetening.
- Chocolate protein powder. One scoop, about 20 g of protein. Whey or a whey-casein blend makes the thickest, smoothest mousse. Use one you already like the taste of, because it’s the only flavor in the bowl.
See the recipe card below for exact amounts.
How to Make High-Protein Chocolate Mousse
- Add both ingredients to a bowl. Spoon in the skyr and add the protein powder on top.
- Whisk. Whisk for about a minute, until it’s smooth, thick and an even chocolate color.
- Eat or chill. Eat it right away, or chill it for 15 minutes for a firmer, more mousse-like texture.
Tips for the Best Protein Mousse
Add texture on top. Berries, cacao nibs, grated dark chocolate or chopped nuts.
Use a whisk, not a spoon. A whisk breaks up the powder and makes the mousse fluffier.
Too thick? Stir in a splash of milk, a teaspoon at a time.
Too thin? Some skyr brands are looser. Add a little more powder or chill it longer.
Taste your powder first. If you don’t like it in a shake, you won’t like it here.
No Protein Powder? Here’s the Real-Food Version
You don’t need protein powder to make a chocolate skyr mousse. Whisk 300 g skyr with 1 to 2 tablespoons of unsweetened cocoa powder and sweetener or honey to taste. You still get about 30 g of protein from the skyr alone, all from real food.
Meal Prep and Storage
Whisk a few portions into jars with lids and keep them in the fridge for up to 3 days. Add the toppings right before eating so they stay crunchy.

FAQ
Can I use Greek yogurt instead of skyr? Yes. Use thick, strained Greek yogurt. It’s slightly lower in protein and a little tangier.
Can I use cottage cheese? Yes, but blend it first for a smooth texture. For a cottage cheese version, see my cottage cheese chocolate mousse.
Which protein powder works best? Whey or a whey-casein blend gives the thickest, creamiest mousse. Plant protein works, but the texture can be grainier, so you may need a splash of milk.
Can I use a different flavor? Yes. Vanilla protein with berries or salted caramel protein both work. Chocolate is my favorite.
Is this protein mousse low carb? It’s high protein and fairly low in carbs. The exact numbers depend on your skyr and protein powder.
