Mix oat flour, protein powder, baking powder, and salt together in a bowl.
Add the egg and milk, then mix well to make a batter.
Heat a pan over medium heat and add a little coconut oil.
Pour the batter onto the pan in your desired pancake size.
When one side is cooked, flip and cook the other side.
Serve on a plate and, if you like, add fruit, yogurt, or nuts as toppings.
