Preheat oven to 400°F. NOTE: If using dark nonstick muffin pan, preheat oven to 375°F.
Combine all-purpose flour, whole wheat flour, SUGAR IN THE RAW®, baking powder, baking soda and salt in a large bowl; set aside.
Blend egg, mashed bananas, buttermilk, corn syrup, oil and vanilla in a medium bowl. Add to flour mixture; stir just until blended. Divide batter evenly into 12 greased (2-1/2-inch) muffin cups. Sprinkle about 1/4 teaspoon SUGAR IN THE RAW® on top of each filled muffin cup.
