Scale

Main Ingredients

  • 2 cups full-fat cottage cheese
  • 4 tbsp powdered sweetener (allulose, monk fruit, or erythritol)
  • 2 tbsp fresh lemon juice (adjust to taste)
  • 2 tsp lemon zest, plus more for topping
  • 1 tsp vanilla extract
  • 2 tbsp heavy cream (optional, if needed for blending)

Instructions

  1. Combine ingredients: In a high-speed blender or food processor, add cottage cheese, powdered sweetener, fresh lemon juice, lemon zest, and vanilla extract.
  2. Blend until smooth: Blend the mixture for 30 to 60 seconds until it becomes completely smooth, creamy, and free of lumps.
  3. Adjust consistency: If the mousse is too thick, add 1 to 2 tablespoons of heavy cream at a time, blending again after each addition until the mousse achieves a silky, light texture.
  4. Chill: Transfer the mousse to serving bowls and refrigerate for 15 to 20 minutes to enhance flavor and improve texture.
  5. Serve topped: Garnish with additional lemon zest and fresh blueberries before serving for a fresh, vibrant finish.

Notes

  • Using full-fat cottage cheese provides a creamier texture and richer flavor.
  • Adjust lemon juice to your preferred level of tartness.
  • Powdered sweeteners like allulose, monk fruit, or erythritol keep this recipe low-carb and diabetic-friendly.
  • The mousse can be made ahead and stored covered in the refrigerator for up to 2 days.
  • Heavy cream is optional and only needed if you want a lighter, more airy consistency.
