In a large bowl, whisk together flour, brown sugar, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt.
In a separate bowl, mix together milk, pumpkin puree, eggs, melted butter, and vanilla extract until well combined.
Pour the wet ingredients into the dry ingredients and stir until just combined. Don't overmix—a few lumps are totally fine!
Heat a griddle or large skillet over medium heat and lightly grease with butter or cooking spray.
Pour 1/4 cup of batter for each pancake onto the hot griddle. Cook until bubbles form on the surface, about 2-3 minutes.
Flip and cook for another 2 minutes until golden brown. Serve warm with maple syrup, butter, and a sprinkle of cinnamon sugar!
