from the King Arthur Flour Baking Book
2 cups whole wheat flour
1 tablespoon baking powder
1 teaspoon salt
2 eggs
1 cup milk
1/2 cup brown sugar
4 tablespoons melted butter or oil (optional)
Combine flour, baking powder, and salt. In a separate bowl, beat eggs and add milk, sugar, and oil (if desired). Pour liquid into dry ingredients and mix just until blended. Fill greased or paper-lined muffin tins about 2/3 full. Bake 20-25 minutes at 400 degrees F.
Variations: Substitute orange juice for the milk, honey for the brown sugar, and add 2 tablespoons grated orange rind or add 1/2 teaspoon ground cinnamon, 1/2 cup chopped apples, and 1/4 chopped nuts.
