How to Make It
Lightly spoon the flours into dry measuring cups, and level with a knife. Combine the flours, cinnamon, baking powder, and salt in a large bowl; stir with a whisk. Combine the milk, oil, and egg yolks; add to the flour mixture, stirring until smooth.
Place the egg whites in a large bowl, and beat with a mixer at high speed until foamy. Add the sugar, beating until soft peaks form. Fold the egg whites into the batter.
Coat a waffle iron with cooking spray; preheat. Spoon about 1/3 cup batter per 4-inch waffle onto hot waffle iron, spreading batter to edges. Cook 5 to 6 minutes or until steaming stops; repeat procedure with remaining batter. Serve with syrup; garnish with strawberries, if desired.
