In a medium-sized mixing bowl, whisk together the part-skim ricotta cheese, egg whites, and vanilla extract until the mixture is smooth and well combined.
Add the oat flour, collagen peptides, baking powder, ground cinnamon, and sea salt to the wet ingredients, stirring gently until just incorporated.
Fold in half of the fresh blueberries, taking care not to over-mix the batter which can make the pancakes tough.
Place a large non-stick skillet over medium-low heat and add the coconut oil, swirling to coat the surface evenly.
Ladle the batter into the skillet to form three to four pancakes, leaving enough space between them for easy flipping.
Press the remaining fresh blueberries into the top of each pancake while the bottom side cooks.
Cook for approximately 3-4 minutes until small bubbles appear on the surface and the edges look set, then carefully flip.
Cook for an additional 2 minutes on the second side until the pancakes are golden brown and cooked through.
Transfer the pancakes to a plate and serve immediately with a drizzle of pure maple syrup.
