Whisk together the eggs, ricotta, juice and vanilla extract and milk until well combed and smooth. Sift in the flour, sweetener (or sugar), baking powder and salt; mix until just combined. Don't over beat the batter. It will be thicker than normal pancake batter. Gently fold in the blueberries.
Heat a nonstick pan or skillet over low-medium heat. Grease with a small amount of butter (or oil spray) and pour 1/4 cup of batter onto the pan. Fry until golden and set on the underside; gently flip and cook the other side until browned and cooked through. Repeat with remaining batter.
Serve with extra blueberries, maple syrup or any toppings you desire.
