1/4 c. milk
1 c. fresh blueberries
cinnamon sugar for dusting

-In medium bowl, combine flour sugar, baking powder, soda, salt and whisk to combine thoroughly.
-In large bowl, combine egg, oil. vanilla, yogurt milk and whisk to combine thoroughly.
-Fold dry ingredients into wet and stir until just combined (will be lumpy and thick.)
-Fold in blueberries and using ice cream scoop to spoon, divide batter evenly among 6 muffin cups.
-Generously sprinkle tops of muffins with cinnamon sugar.
-Place in oven and bake until toothpick inserted in center of muffin is removed clean, about 12-15 minutes.
