In a large bowl, whisk together the flour, baking powder, ginger, cinnamon, nutmeg, and brown sugar. Set aside.
In a separate bowl, whisk the egg, milk, molasses, melted butter, and vanilla extract until smooth and combined.
Pour the wet ingredients into the dry ingredients and mix gently until just combined. Be careful not to overmix — lumpy batter is perfect for fluffy waffles!
Preheat your waffle iron and lightly grease it with non-stick spray or butter. Pour the batter onto the iron, close, and cook according to the manufacturer’s instructions, usually about 4-5 minutes. Once golden brown, serve with your favorite toppings! 🍓
