Place 2 cups of rolled oats in a high-powered blender or food processor. Process until you have 2 cups of fine oat flour. (Skip this step if you’re using pre-packaged oat flour.)
In a medium bowl, stir together the oat flour, baking powder, cinnamon, and salt.
In a large bowl, mix the eggs, coconut milk, coconut oil, and vanilla extract. Add the dry ingredients and stir to combine.
Heat a griddle pan over medium high heat. Lower the heat to medium low, then pour circles of batter onto the griddle. Use about 1/4 cup of batter for each pancake to get 12 pancakes. Cook for one to two minutes on each side, flipping when the surface of the pancakes are dotted with small bubbles.
