In a medium bowl, whisk together the oat flour, protein powder, baking powder, cinnamon, ginger, and nutmeg.
Add the egg whites, almond milk, vanilla extract, and maple syrup to the dry ingredients and stir until just combined.
Fold the finely grated carrots into the batter.
Heat a non-stick skillet over medium heat and lightly grease with cooking spray.
Pour approximately 1/4 cup of batter for each pancake onto the skillet.
Cook for 2 to 3 minutes until bubbles appear on the surface, then flip and cook for an additional 1 to 2 minutes until golden brown.
Repeat with the remaining batter and serve immediately.
