Preheat oven to 375 degrees F. Line muffin tin with liners, or spray with non-stick spray.
In a large bowl, mix sugar and oil. Add in the egg and whisk until light and fluffy. Add in the remaining ingredients, expect for the blueberries. Once everything is combined, gently fold in the blueberries. Use an icecream scoop to fill the baking cups.
Top the muffins with additional 2-3 blueberries each and a sprinkle of turbinado sugar.
Bake for 25-30 minutes until golden brown. Remove from oven and enjoy!
