2 cups (280 g) all-purpose flour
1/4 cup (50 g) cornmeal (optional, see note above)
1/3 cup (65 g) white granulated sugar
2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon sea salt
4 large eggs, separated
2 cups whole milk, divided
6 tablespoons (85 g) melted butter
2 teaspoon vanilla extract
1/8 teaspoon cream of tartar
2/3 cup (70 g) Dutch-processed cocoa powder
2/3 cup (145 g) dark brown sugar
Serve with your choice of:
Slightly sweetened whipped cream
Ice Cream of your choice
1. Place the flour, cornmeal (if using) sugar, baking powder, baking soda, and salt in a large mixing bowl. Place the egg yolks, 1 1/2 cups of the whole milk (saving 1/2 cup for later), melted butter and vanilla extract in a medium bowl and beat to blend.
2. Place the egg whites and the cream of tartar in the bowl of a stand mixer fitted with a wire whisk and beat until stiff peaks form. Make a well in the middle of the dry ingredients and add the milk mixture in the middle. Stir with a rubber spatula by hand until the ingredients are blended (but try not to overmix). Add the egg whites and fold until they are incorporated (draw the spatula down sideways, and lift up flat “folding” the batter over the egg whites, repeating until they are blended in).
3. Scoop out 1 1/2 cups of the batter and reserve it in a glass measuring cup with a spout. Place the remaining 1/2 cup milk, cocoa powder and dark brown sugar in another bowl and whisk until blended (feel free to use the egg white bowl without cleaning it – that’s what I did). Add the chocolate mixture to the remaining waffle mixture and stir with a rubber spatula by hand until blended.
4. Heat your waffle iron according to the instructions. Once heated, drizzle 3-4 tablespoons of vanilla batter over the iron, then immediately pour the recommended amount of chocolate batter over it. Cook until done and repeat with remaining batter. Place finished waffles on a baking sheet in the oven turned to 200˚F if you wish to keep warm. Serve with slightly sweetened whipped cream, fresh fruit, maple syrup or ice cream of your choice.
