Preheat oven to 350 degrees. Grease muffin tin with coconut oil until covered. In a blender or food processor, blend all ingredients together except the blueberries until smooth. Pour batter into each tin about 3/4 of the way from the top. Add 3-4 blueberries to each tin.
Place in tin in oven and cook for 20 minutes or until a toothpick comes out smooth.
