01 - Heat the waffle iron according to the manufacturer's guidelines.
02 - In a large bowl, whisk together flour, brown sugar, baking powder, baking soda, salt, ground ginger, cinnamon, cloves, and nutmeg until evenly blended.
03 - In a separate bowl, beat the eggs then add milk, molasses, melted butter, and vanilla extract. Whisk until thoroughly combined.
04 - Pour the wet mixture into the dry ingredients and gently stir until just combined. Maintain some lumps to avoid overmixing.
05 - Lightly grease the waffle iron with oil or nonstick spray to prevent sticking.
06 - Pour approximately 1/2 to 3/4 cup of batter per waffle onto the preheated iron. Cook for 3 to 5 minutes or until golden brown and crisp.
07 - Place cooked waffles in a low oven at about 200°F (95°C) to keep warm while cooking the remaining batter.
08 - Serve waffles hot, drizzled generously with warmed maple syrup. Optionally top with whipped cream and toasted pecans.
