Preheat a griddle or large nonstick skillet over medium heat.
In a large mixing bowl, whisk together the flour, baking powder, salt, cinnamon, ginger, and nutmeg.
In a separate medium bowl, whisk the brown sugar, granulated sugar, vanilla extract, pumpkin puree, eggs, melted butter, and milk until combined.
Pour the wet mixture into the dry ingredients. Gently whisk until just combined. The batter should remain slightly lumpy, so avoid overmixing.
Let the batter rest for 5 minutes. This short resting time helps create soft and fluffy Pumpkin Pancakes.
Lightly butter the hot griddle or coat it with nonstick cooking spray.
Pour about 1/3 cup of batter onto the griddle for each pancake. Gently spread the batter into a round shape if necessary.
Cook for approximately 3–4 minutes, or until the edges begin to set and the underside is golden brown. Flip carefully and cook the second side until golden and cooked through.
Serve warm with your favorite toppings, such as butter, maple syrup, whipped cream, chopped pecans, or walnuts.
