Ingredients

2 cups cottage cheese, preferably full-fat for a creamier texture
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 (if needed for blending)
½ cup fresh blueberries for topping

Instructions

Step 1: In a high-speed blender or food processor, combine cottage cheese, powdered sweetener, lemon juice, lemon zest, and vanilla extract. Blend for 30–60 seconds until completely smooth.
Step 2: If the mousse is too thick, add 1–2 tablespoons of heavy cream at a time and blend again until the mixture is silky and light.
Step 3: For the best flavor and texture, refrigerate the mousse for 15–20 minutes before serving.
Step 4: Serve topped with fresh blueberries and a sprinkle of lemon zest.

Tips & Variations

Use full-fat cottage cheese for a richer, creamier mousse. For a lighter version, low-fat cottage cheese works but may be less creamy.
Adjust the powdered sweetener to your preference, or substitute with honey or maple syrup if you prefer natural sweeteners.
Try adding a few fresh mint leaves on top for a fresh herbal note.
Swap blueberries with raspberries or sliced strawberries for variation in flavor and color.

Storage

Store the mousse in an airtight container in the refrigerator for up to 2 days. Stir gently before serving if it separates slightly. It’s best enjoyed chilled, so serve cold or after a brief refrigeration.

Can I prepare this recipe ahead of time?

Yes, you can prepare the mousse in advance and refrigerate it for up to 2 days. Just give it a quick stir before serving to restore its smooth texture.
