Ultra-Low-Carb Chocolate Fudge Protein Mousse
Prep time: 5 minutes | Chilling time: 1–2 hours | Yield: 2 large portions
Ingredients
-
The Secret Creamy Base: 1.5 cups full-fat cottage cheese (or 5% plain Greek yogurt) — Don't worry, blending completely removes the texture, leaving a rich, cheesecake-like thickness.
-
The Protein Boost: 1.5 scoops (~45g) Chocolate Whey or Whey/Casein blend protein powder
-
Rich Chocolate Flavor: 3 tbsp unsweetened dark cocoa powder
-
Sweetener: 3–4 tbsp powdered erythritol, allulose, or a few drops of liquid monk fruit (adjust to taste)
-
The Binder (For Thickness): ¼ tsp xanthan gum (This is the secret to getting that dense, scoopable fudge structure)
-
Splash of Liquid: 2–3 tbsp unsweetened almond milk or heavy cream (only as needed to help the blender turn)
-
Enhancers: 1 tsp pure vanilla extract and a tiny pinch of sea salt (to bring out the chocolate notes)
Step-by-Step Instructions
-
Blend the Base Smooth: Add the cottage cheese (or Greek yogurt), vanilla extract, and a tiny splash of almond milk into a high-speed blender or food processor. Blend on high for 60 seconds until completely silky, glossy, and entirely lump-free.
-
Add the Dry Ingredients: Add the chocolate protein powder, unsweetened cocoa powder, sweetener, xanthan gum, and a pinch of salt to the blender.
-
Process Until Thick: Blend again on a lower speed, pulsing as needed. The mixture will quickly become very thick and velvety. If it’s too thick to blend, add another splash of liquid one teaspoon at a time.
-
Smooth and Swirl: Spread the mousse evenly into a glass dish. Use the back of a spoon to create those beautiful aesthetic swirls across the top surface, just like in the photo.
-
Set: Place the dish in the fridge for 1 to 2 hours. The xanthan gum and protein will set the mousse into a dense, fudge-like consistency that holds its shape perfectly when scooped.
Pro-Tips for the Best Texture
Want a "Frosty" Style? Pop the dish into the freezer for 45 minutes instead of the fridge. It chills the fats down to create a texture that replicates gourmet chocolate gelato.
