In a large mixing bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and brown sugar until evenly combined.
1 cup all-purpose flour, 1 teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon ground cinnamon, ¼ teaspoon ground nutmeg, ¼ cup brown sugar
In a separate bowl, mix the pumpkin puree, milk, egg, and melted butter until smooth and well blended.
½ cup pumpkin puree, ½ cup milk, 1 large egg, 2 tablespoons melted butter
Pour the wet ingredients into the dry ingredients and gently stir just until combined. Be careful not to overmix, as the batter should remain slightly lumpy for the best texture.
Heat a non-stick skillet or griddle over medium heat and lightly grease with cooking spray or butter. Using a small ladle or cookie scoop, pour portions of batter onto the skillet, about 3-4 inches in diameter. Cook for 2-3 minutes on each side, flipping once the edges appear set and bubbles form on the surface.
Cooking spray for frying
When both sides are golden brown and cooked through, remove the pancakes from the skillet and serve immediately with your favorite toppings like maple syrup, whipped cream, or chopped nuts.
