In a large mixing bowl, whisk together sifted flour, baking powder, cinnamon, nutmeg, ginger, and salt until evenly combined.
In a separate bowl, beat the eggs gently, then stir in the milk, pumpkin purée, sugar, and melted butter until smooth.
Pour the wet mixture into the dry ingredients and gently fold together using a spatula until just combined; do not overmix to keep the pancakes fluffy.
Preheat a non-stick skillet or griddle over medium heat, then lightly grease if necessary. Pour 1/4 cup of batter onto the hot surface for each pancake.
Cook the pancakes for 2–3 minutes, until bubbles form on the surface and the edges look set, then gently flip them with a spatula.
Cook for another 2–3 minutes until golden brown and cooked through, then transfer to a plate.
Repeat the process with the remaining batter, adjusting the heat as necessary to prevent burning.
Serve the pancakes warm, topped with your favorite toppings like syrup, whipped cream, or additional pumpkin spice if desired.
