Making these pancakes is a straightforward process that will fill your kitchen with the inviting aroma of pumpkin and spices. Follow these steps:

1. Prepare the Dry Ingredients: In a large mixing bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, ginger, salt, and brown sugar until well combined.
2. Mix the Wet Ingredients: In a separate bowl, whisk the pumpkin puree, milk, egg, vanilla extract, and melted butter until smooth. Ensure the pumpkin puree is thoroughly incorporated to avoid lumps.
3. Combine Wet and Dry Mixtures: Gradually pour the wet ingredients into the dry mixture, stirring gently with a spatula or wooden spoon. Mix until just combined—be careful not to overmix, as this can make the pancakes tough.
4. Preheat the Griddle or Pan: Heat a non-stick griddle or skillet over medium heat. Lightly grease with cooking spray or a small amount of butter.
5. Cook the Pancakes: Pour approximately ¼ cup of batter for each pancake onto the hot griddle. Cook until bubbles form on the surface, and the edges appear set, about 2-3 minutes. Flip the pancakes and cook for another 1-2 minutes until golden brown.
6. Keep Warm: Transfer cooked pancakes to a plate and cover with a clean kitchen towel to keep warm while you cook the remaining batter.
7. Serve: Once all pancakes are cooked, stack them high and serve with your favorite toppings.
