- Preheat your waffle iron according to the manufacturer's instructions.
- Separate the egg yolks from the whites. Whisk yolks with buttermilk and brown sugar until combined.
- In a separate bowl, whip egg whites and cream of tartar with a mixer on high speed until stiff peaks form (about 4–5 minutes).
- In another bowl, combine flour, baking soda, and cinnamon. Stir in the egg yolk mixture, chopped pecans, vanilla, and melted butter.
- Gently fold whipped egg whites into the batter until just blended.
- Spray the waffle iron with nonstick spray. Pour 2/3 to 3/4 cup batter into the iron and cook per the manufacturer's instructions. Repeat until all batter is used.
- Serve topped with sliced bananas, maple syrup, and powdered sugar.
