Key element — thick Greek yogurt
Use a thick, strained Greek yogurt. Thin yogurt makes a looser mousse. The thickness is what gives this the classic spoonable, almost whipped texture.
Ingredients
Mousse base
- 2 cups plain nonfat or low-fat Greek yogurt (thick style)
- 1 scoop (about 25–30g) chocolate protein powder
- 3–4 Tbsp natural peanut butter (no sugar added)
- 2–3 Tbsp sugar-free sweetener (erythritol, allulose, or monk fruit), to taste
- 1–2 Tbsp unsweetened cocoa powder (optional for deeper chocolate)
- 1 tsp pure vanilla extract
- Pinch of salt
- 1–2 Tbsp milk of choice (only if needed for consistency)
Optional richer version
- 2 oz cream cheese, softened
- or 2–3 Tbsp heavy cream
To serve
- Sugar-free whipped cream
- Chopped pecans or peanuts
- Sugar-free chocolate shavings or a dusting of cocoa
Swaps
- Dairy-free: Use thick coconut yogurt and a plant-based chocolate protein powder.
- Almond butter: Swap peanut butter for almond or cashew butter.
- Extra chocolate: Add more cocoa powder or a few sugar-free chocolate chips.
- Higher protein: Add an extra half-scoop of protein powder.
Instructions
| 1 | Mix the base. In a medium bowl combine the Greek yogurt, chocolate protein powder, peanut butter, sweetener, cocoa powder (if using), vanilla, and salt. If using cream cheese or heavy cream, add it now. |
| 2 | Blend until smooth. Mix with a spoon, whisk, or electric mixer until completely smooth and thick. Add a tiny splash of milk only if the mixture is too stiff. |
| 3 | Taste and adjust. Taste the mousse and add more sweetener, peanut butter, or cocoa if needed. The flavor will deepen slightly once chilled. |
| 4 | Portion. Spoon or pipe into 4 small glasses, cups, or ramekins. For a lighter texture, you can fold in a little whipped cream before portioning. |
| 5 | Serve. Enjoy immediately or chill for 10–15 minutes if you prefer it colder. Top with whipped cream, chopped nuts, and chocolate shavings just before serving. |
Pro tips
- Use thick Greek yogurt for the best texture — thinner yogurts make a looser mousse.
- Natural peanut butter (oil on top) gives better flavor than sweetened versions.
- An electric mixer or immersion blender gives the smoothest, airiest result.
- If the mousse is too soft, stir in a little more protein powder or chill it briefly.
- These keep well in the fridge for a couple of days — perfect for meal prep.
