2 1/2 cups all-purpose flour1/3 cup packed light brown sugar2 1/4 teaspoons baking powder1 teaspoon baking soda1/2 teaspoon salt2 teaspoons ground cinnamon1 teaspoon ground ginger1/4 teaspoon ground cloves4 large eggs, separated2 cups well-shaken buttermilk1 cup canned solid-pack pumpkin3/4 stick (6 tablespoons) unsalted butter, melted
Vegetable oil for brushing waffle iron or cooking spray
Preheat oven to 250°F and preheat waffle iron. Sift together flour, brown sugar, baking powder and soda, salt, and spices. Whisk egg yolks in a large bowl with buttermilk, pumpkin, and butter until smooth. Whisk in dry ingredients just until combined.
In a mixing bowl with a whisk attachment, whisk the egg whites until they hold soft peaks (as in, far softer than the over-beaten whites you’ll see in my picture above). Folk them gently into the waffle batter, until just combined.
Brush waffle iron lightly with oil and spoon batter (about 2 cups for four 4-inch Belgian waffles) into waffle iron, spreading quickly. Cook according to manufacturer’s instructions.
Transfer waffles to rack in oven to keep warm and crisp. Make more waffles in same manner.
