In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg until well combined.
In another bowl, mix together the pumpkin puree, milk, eggs, brown sugar, and vanilla extract until smooth.
Gradually pour the wet ingredients into the dry ingredients, stirring gently until just combined (a few lumps are okay). Do not overmix.
Fold in the chocolate chips until evenly distributed throughout the batter.
Heat a non-stick skillet or griddle over medium heat and add a small amount of butter or oil.
Once the skillet is hot, pour 1/4 cup of batter for each pancake onto the skillet. Cook until small bubbles form on the surface and the edges appear set (about 2-3 minutes).
Flip the pancakes carefully and cook for another 2-3 minutes until golden brown and cooked through. Repeat until all batter is used.
Serve warm, stacked high, with maple syrup drizzled on top and a sprinkle of extra chocolate chips if desired.
Notes
Serve pancakes on a colorful plate, topped with whipped cream, a dusting of powdered sugar, and a sprinkle of chopped pecans for added texture.
