Preheat oven to 350 degrees. Spray 2 mini loaf pans with cooking spray with flour like Baker's Joy.
Whisk the egg in a medium-sized mixing bowl. Add the sugar, corn oil, vanilla, milk and stir. Stir in the mashed bananas.
Stir the flour into the banana mixture. Add chopped nuts.
In a small bowl mix the Tablespoon of flour and the blueberries until berries are coated with flour. This will keep berries from "bleeding" in the bread. Gently stir the blueberries into the bread mixture.
Fill loaf pans about 1/2 to 3/4 full; don't be tempted to overfill, the loaves will be ugly.
Bake at 350 degrees for 35-45 minutes or until a skewer or straw inserted into the center of the loaf comes out clean. Cool on rack and serve with butter or cream cheese.
Yield: 2 small loaves
