In a medium bowl, whisk together the dry ingredients (flour through cinnamon).
Combine the remaining ingredients in a separate bowl. Add the wet mixture to the dry, stirring just until combined.
Coat a waffle iron with cooking spray and preheat. Spoon the batter onto the hot waffle iron, spreading the batter to the edges. Cook for 5 minutes, or until the steaming stops (follow your waffle iron instructions). Repeat the procedure with the remaining batter. Serve with butter and warmed maple syrup.
