In a large mixing bowl, whisk together the oat flour, vanilla protein powder, baking powder, ground cinnamon, and sea salt until well combined.
In a separate medium bowl, stir together the part-skim ricotta, egg whites, lemon zest, and vanilla extract until the mixture is smooth.
Pour the wet ingredients into the dry ingredients and stir gently with a spatula until just incorporated, being careful not to overmix the batter.
Gently fold the fresh blueberries into the batter using a slow circular motion.
Heat the coconut oil in a large non-stick skillet or griddle over medium-low heat.
Ladle approximately 0.25 cup of batter onto the skillet for each pancake, leaving space between them.
Cook for 3 to 4 minutes until small bubbles appear on the surface and the edges look set.
Carefully flip the pancakes and cook for an additional 2 minutes until they are golden brown and cooked through.
Transfer to a plate and serve immediately while warm.
