In a blender, process the cottage cheese, pumpkin puree, eggs, vanilla extract, and maple syrup until the mixture is smooth and no curds remain.
In a medium mixing bowl, whisk together the flour, baking powder, pumpkin pie spice, and salt until evenly distributed.
Pour the blended wet ingredients into the dry ingredients and stir with a spatula until just combined; avoid overmixing to maintain texture.
Preheat a non-stick griddle or large skillet over medium heat and lightly coat with butter.
Ladle approximately 1/4 cup of batter per pancake onto the hot surface.
Cook for 2-3 minutes until bubbles form on the surface and the edges appear set.
Flip the pancakes carefully and cook for an additional 1-2 minutes until golden brown and cooked through.
Transfer to a plate and serve warm with maple syrup or Greek yogurt.
