Add raw cashews, full-fat coconut milk, lemon juice, agave and coconut oil to a food processor
Process ingredients until a creamy and smooth texture is formed (2-3 minutes)
Once a smooth and creamy texture is achieved, add in the frozen blueberries and process until creamy again (another 1-2 minutes)
Once a creamy texture is achieved, transfer your blueberry mousse to an airtight container.
Enjoy or store in your fridge for up to 5 days (if it lasts that long)
