Preheat the oven to 350°F and lightly grease the bottom of an 8- or 9-inch loaf pan. In a large bowl, beat together the sugar, milk, applesauce, oil, and eggs until smooth. Add the remaining dry ingredients (except the blueberries) and mix until combined, then gently fold in the blueberries. Pour the batter into the prepared pan and spread evenly. Bake for 45–55 minutes, or until a toothpick inserted into the centre comes out clean. Let the loaf cool in the pan for 10 minutes, then remove and transfer to a wire rack to cool completely.
