Begin by straining the full-fat cottage cheese using a fine mesh sieve. Allow it to drain for about 15 minutes to remove excess liquid, which will enhance the creaminess.

In a food processor, combine the strained cottage cheese, creamy natural peanut butter, honey or maple syrup, and vanilla extract. Add a pinch of salt if desired. Blend for approximately 45 to 60 seconds until smooth and velvety.

Check the texture of your mousse; if it's too thick, gradually add 1 to 2 tablespoons of milk while blending. Continue blending for another 15 to 30 seconds until light and airy.

Transfer the blended mousse into a bowl and cover. Place it in the refrigerator for 15 to 20 minutes, allowing the flavors to meld beautifully.

Once chilled, spoon the mousse into small bowls or jars. Top with fresh fruits, chopped nuts, honey, or chocolate shavings before serving.
