Add the following ingredients to a blender in the order listed: cottage cheese, pumpkin, egg, vanilla, baking powder, cinnamon, and oats. Blend for a full minute on high speed, until the batter is smooth. This is a very thick batter, don't try to add liquid.
Cook:
Heat a non-stick griddle or large pan over medium-high heat. Once hot, grease, spray, or melt butter on the hot surface. Immediately, pour ¼ cup of batter per pancake onto the greased pan. I've found that using a measuring scoop or soup spoon works best, then using the back of it to spread it out on the pan.
Cook the pancakes for 2 minutes until the edges begin to look defined and some bubbles form. Flip them over and cook for two more minutes on the other side. Flip them only once, and don't use the spatula to press them down; you'll end up with dense pancakes.
Serve:
Plate a few pancakes on a plate and top them with your favorite toppings and syrups.
