1. In a large bowl, whisk together the flour, cornmeal, brown sugar, baking powder, baking soda and salt. In a separate bowl, mix together the Greek yogurt or sour cream, milk, melted butter and egg yolks. Combine the wet ingredients with the dry until fully incorporated. Using the whisk attachment on a standing mixer or a hand-held mixer, beat the egg whites until fluffy and slightly stiff. Fold into the batter.
2. Heat your waffle iron and lightly spray with nonstick spray or brush with melted butter. Cook waffles until golden and slightly crisp.

Caramelized Bananas

1. While waiting for the waffles to cook, heat a large sauté pan over medium heat. Add the butter, brown sugar and maple syrup and stir to combine. When mixture begins to bubble, add the Cognac. Once the Cognac has evaporated, add the sliced bananas. Cook bananas for about 1 to 2 minutes per side until browned and soft. Set aside.
2. Once your waffles are cooked, drizzle a heaping spoonful of peanut butter across the top of each waffle (this is easier to do when the waffle is still warm). Place a spoonful of the caramelized banana sauce on top then dust with powdered sugar. Enjoy!
