• In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda and salt.
• Using a separate mixing bowl, whisk together the egg yolks, milk, oil and vanilla.
• Add the wet ingredients to the dry ingredients and stir in.
• In the mixing bowl of a stand mixer with the whisk attachment, whisk the egg whites until stiff peaks form.
• With a rubber spatula, gently fold the whipped egg whites to the batter. Stir until no white streaks remain.

To make 2 waffles at one time:

• Preheat a double-sided flipping waffle iron and spray both sides with non-stick spray.
• Pour half of the batter into each side of the double-sided waffle iron.
• Cook until the waffles are golden brown, about 7 - 10 minutes. Follow the cooking instructions for your specific waffle iron. Mine has lights on it that tell you when to flip it and when it’s done cooking.
• Repeat until all of the batter is used.
• Top with your favorite toppings like maple syrup, fruit, whipped cream, etc. Serve immediately.
