In a large bowl, whisk together mashed banana, ricotta and two eggs.
Stir in buckwheat pancake mix, cinnamon and salt then begin adding milk until desired consistency is reached. For thinner pancakes, add all 2 cups of milk.
Carefully fold in the blueberries then set aside.
Heat griddle on high and spray with non-stick spray.
Using a 1/4 cup ladle or ice cream scoop, pour pancake batter onto hot griddle. When bubbles begin to form and pancake is golden brown, flip to the other side.
