In a large bowl combine flour, brown sugar, baking powder, salt, cinnamon, nutmeg, and ginger. In a small bowl stir together milk, pumpkin, eggs, and oil. Add pumpkin mixture all at once to flour mixture. Stir just until moistened (batter should be slightly lumpy).

For each pancake, pour about 1/4 cup of the batter onto a hot, lightly greased griddle or heavy skillet. Spread batter, if necessary. Cook over medium heat for 1 to 2 minutes on each side or until pancakes are golden brown, turning to second sides when surfaces are bubbly and edges are slightly dry. Serve warm. If desired, serve with maple syrup and/or nuts.
