These classic waffles are crispy on the outside, light and fluffy on the inside, along with a scrumptious buttery taste.
Mix both flours, sugar, baking powder and salt in a large bowl.
In a separate bowl, combine milk, egg yolks and vanilla. Mix well.
Beat egg whites until stiff (not dry) peaks form. Set aside.
Add milk mixture to dry ingredients. Stir until just combined. Stir in melted butter and mix until incorporated.
Gently fold in egg whites.
Follow waffle maker instructions for cooking.
