1 lg. egg
3/4 c. packed light brown sugar
1 1/3 c. mashed ripe bananas
1/2 c. raisins or walnuts
1/3 c. vegetable oil
1 tsp. vanilla extract
3/4 c. all-purpose flour
3/4 c. whole wheat flour
1/2 c. oat bran
2 tsp. baking powder
1/2 tsp. baking soda
1 tsp. cinnamon
1/4 tsp. salt

Heat oven to 375 degrees. Grease muffin cups or use foil or paper baking cups. Beat egg and sugar in medium-size bowl. When smooth, beat in bananas, raisins, oil, and vanilla. Let stand a minute. Thoroughly mix flours, bran, baking powder, baking soda, cinnamon, and salt in a large bowl. Add banana mixture and fold in with a spatula just until dry ingredients are moistened. Scoop batter into muffin cups. Bake 15 to 25 minutes or until brown and springy to the touch in the center. Turn out onto a rack to cool.
