In a large mixing bowl, sift together the flour, brown sugar, baking powder, baking soda, cinnamon, nutmeg, and salt to combine the dry ingredients evenly.
In a separate bowl, whisk the milk, pumpkin puree, eggs, and melted butter until smooth and well combined.
Pour the wet mixture into the dry ingredients and gently fold them together using a spatula, just until no streaks remain. Be careful not to overmix—the batter should be slightly lumpy and thickening.
Preheat a non-stick skillet or griddle over medium heat until hot but not smoking, approximately 350°F (175°C). Lightly grease with butter or oil if necessary.
Pour about 1/4 cup of batter for each pancake onto the skillet, spacing them apart to allow room for spreading. Cook until bubbles form on the surface and the edges look set, about 2–3 minutes.
Flip the pancakes carefully with a spatula and cook for another 2–3 minutes, until golden brown on both sides and cooked through in the center.
Transfer the cooked pancakes to a plate and repeat the process with the remaining batter, adjusting the heat as needed to prevent burning.
Serve the pumpkin pancakes warm, topped with your favorite toppings like syrup, whipped cream, or extra cinnamon for a cozy breakfast experience.
