Blueberry Oatmeal Muffins

To keep muffin batter from turning purple, toss frozen blueberries with flour before adding them to mix. To add more nutrients and fiber to baked goods, substitute half of the all-purpose flour called for whole-wheat flour. If you don’t have buttermilk on hand, you can use 1 tablespoon of white vinegar or lemon juice plus enough milk to measure 1 cup. Stir and let stand for 5 minutes. You can also use 1 cup of plain yogurt or 1-3/4 teaspoons cream of tartar plus 1 cup milk.
