In a bowl, whisk together pumpkin, eggs, butter, and vanilla together. In a separate bowl mix the flour, brown sugar, baking powder, salt, nutmeg and cinnamon. Fold the flour mixture into the pumpkin mixture until well combined.

Preheat a griddle or a large skillet over medium heat. Spray with non stick spray. Spoon about 1/4 cup of batter into the pan. Once tiny bubbles start to appear, flip the pancakes. Cook for an additional 2 minutes. Serve with maple syrup.
