Begin by straining 1 cup of full-fat cottage cheese using a small strainer or sieve for about 1-2 minutes to remove excess liquid.

Set up your 4-cup food processor or high-speed blender to blend all the ingredients together smoothly.

Add the strained cottage cheese to the food processor along with 4 tablespoons of creamy natural peanut butter, 2 tablespoons of honey or maple syrup, and 1 teaspoon of vanilla extract.

Blend the mixture on high for 45-60 seconds, scraping down the sides to ensure all ingredients blend evenly until smooth.

Check the consistency; if too thick, add 1-2 tablespoons of milk gradually while blending.

Transfer the mousse into a bowl, cover, and let it chill in the refrigerator for 15-20 minutes.

Once chilled, portion into small serving bowls and serve as is or add optional toppings like chopped peanuts or chocolate chips.
