Transfer the oats, protein powder, baking powder, baking soda, ground cinnamon, and sea salt (all of the dry ingredients) to a high speed blender and blend for 60 seconds, or until a flour forms. Set aside until ready to use.

Plug in your waffle iron and allow it to heat up for a few minutes. Spray both sides of the heating elements with cooking spray. For large waffles, pour ¾ cup to 1 cup of waffle batter onto the center of the waffle maker, or ⅓ cup to ½ cup for small waffles using a mini waffle maker. Replace the lid and cook for 3 to 5 minutes, or until the waffle is golden brown and cooked through. Repeat for the remaining batter. This recipe makes 4 full Belgian waffles (large waffles), or 8 small waffles.

Serve with your favorite toppings, like butter, sliced bananas (or other fresh fruit), chopped nuts, and honey or pure maple syrup on top. A dollop of almond butter or peanut butter is great too.
