I'm going to make these again today since the ones I made the other day vanished so quickly!

Ingredients

• 3/4 cups whole wheat flour
• 1/2 cup all-purpose flour
• 1 cup quick-cooking oats
• 1/4 cup packed brown sugar
• 2 teaspoons baking powder
• 1/2 teaspoon salt
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon baking soda
• 1/4 teaspoon ground nutmeg
• 1 large egg, lightly beaten
• 1 cup (8 ounces) plain yogurt
• 1/4 cup butter, melted
• 1 cup fresh blueberries

Directions

1. In a large bowl, combine the first eight ingredients. Combine the egg, yogurt and butter; stir into dry ingredients just until moistened. Fold in blueberries.
2. Coat muffin cups with cooking spray or use paper liners; fill three-fourths full with batter. Bake at 400° for 18-22 minutes or until a toothpick inserted in the muffin comes out clean. Cool for 5 minutes before removing from pan to a wire rack. Serve warm.
