1. Prepare Sesame Crunch Topping; set aside. Spray muffin cups with nonstick cooking spray or use paper liners.
2. Preheat oven to 400°F.
3. Combine bananas, milk, egg whites, oil and vanilla in large bowl. Combine oats, flours, sugar, baking powder and salt in medium bowl; stir into banana mixture until just moistened. (Batter will be lumpy.) Fill prepared muffin cups about 3/4 full. Sprinkle 2 teaspoons Sesame Crunch Topping over batter in each cup.
4. Bake 20 to 25 minutes until golden on top and wooden toothpick inserted into centers comes out clean. Cool slightly in pan before transferring to wire rack. Serve warm.
