Blend the batter: Combine cottage cheese, eggs, oat flour, baking powder, vanilla, and salt in a blender or food processor and blend until smooth, about 30 seconds.
Rest the batter: Let the batter sit for 2-3 minutes to allow the oat flour to absorb moisture and create fluffier pancakes.
Heat your pan: Warm a non-stick skillet over medium heat and lightly coat with cooking spray or butter.
Cook the pancakes: Pour 1/4 cup of batter per pancake onto the hot skillet and immediately press 4-5 blueberries into the top of each pancake.
Wait for bubbles: Cook for 2-3 minutes until bubbles form on the surface and edges look set.
Flip carefully: Use a wide spatula and flip gently, as these pancakes are more delicate than traditional ones, then cook for another 2 minutes until golden brown.
Serve warm: Top with a dollop of Greek yogurt, extra blueberries, and a light drizzle of honey if desired.
