This is an attempt at eating healthier, while still preserving good taste! These waffles cook up nice and fluffy, while the oat bran and whole wheat flour make them healthier. Serve with your favorite fruit or syrup.
Combine the oat bran, whole wheat flour, all-purpose flour baking powder and salt.
Combine the milk, oil, and egg yolk; add to the dry ingredients, stirring just until moistened.
Beat egg whites at high speed with an electric mixer until stiff peaks form; gently fold into the batter.
Coat a waffle iron with cooking spray, and allow waffle iron to preheat. Spoon 1 1/3 cups batter onto hot waffle iron, spreading batter to edges. Bake until lightly browned. Repeat with remaining batter.
