Prepare the Oat Flour: Add the rolled oats to your blender pitcher. Pulse several times until the oats break down into a coarse, flour-like consistency. This step ensures a smooth texture in the final pancake.
Combine All Ingredients: To the oat flour in the blender, add the low-sodium baking powder, no-salt-added cottage cheese, eggs, almond milk, vanilla extract, cardamom, nutmeg, and lemon zest.
Blend the Batter: Secure the lid and blend on medium speed for 20–25 seconds, just until the mixture is fully incorporated and smooth. Avoid over-mixing to keep the pancakes tender. The batter will be relatively thick.
Rest the Batter: Let the batter rest undisturbed in the blender pitcher for at least 5 minutes. This allows the oats to hydrate and the leavening to activate for maximum fluffiness.
Heat the Griddle: Place a cast-iron griddle or large non-stick skillet over medium-low heat. Lightly mist the surface with avocado oil or olive oil spray. The pan is ready when a droplet of water sizzles on contact.
Cook the Pancakes: Using a ¼-cup scoop, pour the batter onto the hot griddle. Cook for 2–3 minutes until the edges look set and bubbles begin to appear on the surface. Carefully flip and cook for another 2 minutes until the second side is golden-brown and the center is cooked through. Repeat with remaining batter.
