Other adaptations of ours for our kid include putting in walnuts, finely chopped, and cooking the muffins in a mini muffin tin.
I also experimented with two different kinds of paper muffin cups, and I highly recommend If You Care Baking Cups. They are unbleached, greaseproof, and they don't stick to your muffins. Amazing!
1 cup Wheat Bran
1 1/2 cups Whole Wheat Flour
1/2 cup Raisins (Unsulfured)
1 tsp. Baking Powder
1 tsp. Baking Soda
1 cup Milk
1/2 cup Blackstrap Molasses
3/4 cup Mashed Bananas
1/4 cup finely chopped Walnuts
2 Tbsp. Oil
2 Eggs, beaten
Preheat oven to 400F. Combine wheat bran, flour, baking soda and baking powder. Stir in nuts and raisins. In a separate bowl, blend bananas, milk, molasses, oil and egg. Add to dry ingredients and stir just until moistened. Spoon into greased muffin tin (or paper muffin cups) and bake for 15-20 minutes. Makes 12 marvelous muffins.
