Finally a use for that vanilla frozen yogurt that you bought and just didn't like! Any kind of fruit can be used also!
1Preheat oven to 375 degrees. Combine all ingredients but blueberries. Mix just until combined. Toss blueberries with a small amount of flour. Stir into muffin mixture. Spray muffin tins with non stick cooking spray. Fill each cup 3/4 full. Sprinkle with sugar. Bake at 375 degrees for 20 minutes.
