1 3/4 cups whole wheat flour
3/4 cup oat bran
1/3 cup sugar
1 tablespoon baking powder
1 (11 ounce) can mandarin orange segments, undrained
2 egg whites
1 teaspoon vanilla or almond extract
3/4 cup fresh or frozen blueberries
Preheat oven to 350 degrees F. Prepare a 12 cup muffin pan by spraying with nonstick cooking spray or use paper liners. In a large bowl, combine the flour, oat bran, sugar, and baking powder; stir to mix well. Crush the orange segments slightly and add the oranges and their syrup, egg whites, and extract to the flour mixture; stir just until the dry ingredients are moistened. Fold in blueberries. Spoon into prepared muffin cups and bake for 15 - 18 minutes or until a toothpick inserted in the center comes out clean. Cool for 5 minutes before removing from the pan.
The batter is stiff because there is no oil. The egg whites and juice from the mandarin oranges provide the moisture.
