Place the rolled oats in a high-speed blender and pulse until they reach a fine, flour-like consistency.
Add the Greek yogurt, liquid egg whites, baking powder, vanilla extract, and cinnamon to the blender and process until the batter is smooth.
Heat a large non-stick skillet over medium heat and cook the bacon slices until they are crispy and golden.
Drizzle half of the maple syrup over the bacon, turning the slices to coat them in a sticky glaze, then remove them from the pan.
Wipe the skillet clean and lightly coat with a touch of cooking spray if needed, then pour the batter to form three large pancakes.
Cook for 2-3 minutes until bubbles appear on the surface, flip carefully, and cook for another 2 minutes until the pancakes are cooked through.
Plate the pancakes, top with the glazed bacon, and finish with the remaining maple syrup, sea salt, and black pepper.
