In a large mixing bowl, combine flours, baking powder, ginger, nutmeg, salt, cinnamon and brown sugar.
In another medium sized mixing bowl, combine egg whites, milk, oil and pumpkin. Add pumpkin mixture to flour mixture and stir until just moistened. If batter seems too thick, add a little milk to thin it out to desired consistency.
Heat griddle or skillet on medium heat and spray with cooking spray. Pour batter onto heated griddle or skillet using a 1/4 cup measuring cup. Flip when bubbles appear at the top. Serve with syrup and enjoy!
