Preheat oven to 400 degrees and grease muffin tin. In mixing bowl combine egg, oil, applesauce, banana, milk and yogurt.
Sprinkle dry ingredients on top of wet: flour, bran, sugar, baking powder and salt. Mix just until combined, then stir in berries or chopped fruit.
Fill muffin cups with batter. Bake 20 min., or until toothpick inserted in center of one comes out clean and middle springs back when touched.
Cool for approx. 10-15 min., then run knife around edges and release muffins. Cool further on counter top or wire rack.
STEVIA: For one dozen, lower sugar to 1/2 c. and add 12 drops of liquid stevia.
CRUMB TOPPING: Mix 1/2 c. flour, 1/2 c. sugar, cut in 4 Tbsp. butter and distribute over muffins before baking. Both plain and blackberry muffins are shown in picture.
