In a large mixing bowl, whisk together the whole wheat flour, baking powder, cinnamon, and nutmeg until evenly combined. The dry ingredients should look smooth and uniform, with no lumps.
Add the pumpkin puree, milk, maple syrup, and eggs to the dry mixture. Whisk everything together until the batter is smooth and slightly frothy, with no dry pockets remaining. The batter should be pourable but thick.
Preheat a skillet or griddle over medium heat until it’s hot enough to sizzle when a few drops of water are sprinkled on it. Lightly brush with oil or butter to prevent sticking.
Pour 1/4 cup portions of batter onto the skillet, spacing them out to allow room for spreading. Cook until bubbles form on the surface and the edges look set, about 2-3 minutes.
Use a spatula to gently flip each pancake and cook for another 2-3 minutes until golden brown and cooked through. The pancakes should feel slightly firm but tender when pressed.
Transfer the cooked pancakes to a plate and repeat with the remaining batter. Keep them warm while you finish cooking, if desired, by covering with foil or placing in a warm oven.
Serve the fluffy pumpkin pancakes hot, topped with your favorite syrup, a dusting of cinnamon, or fresh fruit. Enjoy their warm, cozy aroma and tender texture.
