Grease large 1½ pound loaf pan and preheat oven to 350°F.
In a large mixing bowl or mixer, combine sugar, flour, baking powder and salt.
In a separate bowl, beat egg, milk and oil.
Gradually add dry mixture to wet until just moist.
Fold in blueberries. (Optional: coat them in flour first, to help prevent sinking to the bottom of the pan.)
Pour batter into pan (up to 1½ inches below the top) compensating for rise.
Optional: sprinkle sugar on top just before baking if you're not topping with glaze.
Bake 50-60 minutes.
Allow to cool on wire rack 10-15 minutes before removing from loaf pan.
If you're adding a glaze, mix all glaze ingredients together in a small bowl while the bread cools. Add glaze after loaf is cooled. Serve and enjoy!
