In a large mixing bowl, whisk together the flour, sugar, cinnamon, nutmeg, baking powder, and salt until evenly combined.
In a separate bowl, beat the eggs, then stir in the pumpkin puree, milk, and melted butter until smooth.
Pour the wet mixture into the dry ingredients and gently fold together with a spatula until just combined; avoid overmixing to keep the batter light.
Preheat a griddle or non-stick skillet over medium heat until warm; lightly grease with butter or cooking spray.
Pour 1/4 cup of batter onto the hot skillet for each pancake. Cook until bubbles form on the surface and the edges look set, about 2–3 minutes.
Flip the pancakes gently using a spatula and cook until golden brown on the other side, about 2 minutes more.
Transfer the cooked pancakes to a plate and repeat with the remaining batter, adjusting heat as needed to prevent burning.
Serve the pancakes warm, topped with cinnamon sugar, syrup, or your favorite fall-inspired toppings.
