Preheat waffle iron.
Combine flour, sugar, cinnamon, baking powder, ginger, nutmeg and baking soda in a large bowl; mix well and set aside.
Whisk together eggs, milk, pumpkin puree and butter in another large bowl. Stir in flour mixture until a slightly lumpy batter forms.
Spray waffle iron with cooking spray; add batter and cookuntil waffles are set and golden brown, about 2 minutes.
Serve sprinkled with copped pecans and drizzled with maple syrup.
Tip: If you do not have a waffle iron you can use the batter to make pancakes.
