Place cottage cheese, eggs, pumpkin puree, and vanilla extract into a blender and process until smooth.
Add oat flour, pumpkin pie spice, baking powder, maple syrup, and salt to the blender.
Pulse the mixture 3 to 5 times until the dry ingredients are just incorporated.
Preheat a non-stick skillet or griddle over medium-low heat and coat with a small amount of butter.
Ladle 1/4 cup of batter per pancake onto the heated surface.
Cook for 3 to 4 minutes until small bubbles form on the surface and the edges look dry.
Flip the pancakes carefully with a spatula and cook for another 2 to 3 minutes until golden brown and cooked through.
Transfer to a warm plate and serve immediately.
