To make this Blueberry Lemon Bread, preheat your oven to 350 degrees, spray the sides and bottom of a 9x5 loaf pan with non stick spray and set it aside. Next, add your oil, sugar, eggs, sour cream, lemon and lemon zest to a large mixing bowl and mix together. Add in your flour, baking powder and salt and mix to just combine your ingredients.
Once your batter is together, add 1-1/2 cups fresh blueberries to bowl and toss them with 2 teaspoons of flour. Add your tossed blueberries to your lemon bread batter and gently fold them into the batter. Pour your batter into your loaf pan and bake for 50-60 minutes or until you insert a toothpick into the middle and it comes out clean.
Remove your Blueberry Lemon Bread from the oven and let cool in the loaf pan for 30 minutes. Run a sharp knife around the edges of the inside of the pan and invert your loaf onto a cutting board or plate and then flip again onto a wire rack where it can completely cool.
Once your Blueberry Lemon Bread had completely cooled, add sifted powdered sugar and lemon juice to mixing bowl and whisk to combine. Add more juice to your glaze to thin it out or more powdered sugar to thicken it up depending on preference. Using a spoon, drizzle your glaze over your bread loaf 5-10 minutes before serving and garnish with remaining 1/2 cup fresh blueberries.
