Preheat oven to 350°F (175°C) and line a muffin tin with liners or lightly grease it.
In a bowl, whisk together oat flour, protein powder, baking powder, baking soda, and salt.
In a separate bowl, mix eggs, Greek yogurt, honey or maple syrup, almond milk, oil, and vanilla until smooth.
Gently fold dry ingredients into wet ingredients until just combined.
Carefully fold in blueberries.
Divide batter evenly into muffin cups, filling each about ¾ full.
Bake for 18–22 minutes, until a toothpick inserted comes out clean or with a few moist crumbs.
Cool for 5 minutes, then transfer to a wire rack.
