Preheat oven to 375 degrees F. Line 12 muffin cups with liners** or spray with non-stick cooking spray.
In a medium bowl, whisk together yogurt, milk, oil, egg, vanilla extract, lemon zest, and lemon extract. Set aside.
In a large bowl, stir together flour, sugar, baking powder, baking soda, and salt. Add blueberries to the dry mixture and stir lightly to coat with flour. Make a well in the center and add the wet ingredients, stirring until dry ingredients are just moistened (do not overmix!).
Spoon the batter evenly into the prepared muffin tins (you may wind up with enough batter for 13 muffins). Evenly sprinkle the muffins with a small dusting of sugar.
Bake for 17-20 minutes or until center springs back when lightly touched. Cool for 5 minutes then remove to a wire rack. Enjoy!
