Begin by grinding 1 cup of rolled oats in a blender or food processor until it reaches a fine flour consistency.

In a medium mixing bowl, combine the prepared oat flour with protein powder, sweetener, ground cinnamon, and salt. Then, add milk, egg, vanilla extract, Greek yogurt, and baking powder. Stir until smooth and slightly thick.

Preheat a non-stick skillet or griddle over medium heat for about 2-3 minutes. Lightly coat with cooking spray or butter.

Pour the pancake batter into the skillet, forming small round portions. Cook undisturbed for about 2-3 minutes until bubbles form. Gently scramble the batter until cooked through.

Transfer the pancakes to a warm plate or serve immediately with toppings like fruit or honey. Store leftovers in an airtight container.
