All you need:
1 1/2 cup Semi-Sweet Chocolate Chips
1 cup Unsweetened Cocoa
2 cup all-purpose flour
1 tablespoon baking powder
2 tablespoon granulated white sugar
1/2 teaspoon salt
4 large eggs, separated
4 tablespoon canola oil
2 cup whole milk
All you do:
1. Preheat a waffle iron according to the manufacturer's directions. Sift the flour, cocoa, and baking powder into a bowl. Add the sugar and salt and whisk to thoroughly mix. In another bowl, whisk together the milk, egg yolks, and oil. Add to the flour and whisk gently until just combined. In clean, dry bowl, beat the egg whites with an electric beater at medium speed until they form soft peaks. Fold into the batter and mix in the chocolate chips.
2. Ladle one-third of the batter onto the center of the waffle iron. Close the top and cook until the waffle is crispy on both sides. Follow the manufacturer's instructions for cooking time.
Serve immediately. Makes 6 waffles.
