The first step is to preheat the oven to 350°F and spray a loaf pan with baking spray, or you can even spread some butter. Set aside
Then, in a small bowl, combine the lemon zest and sugar. Using your fingers, combine until the sugar is all coated with zest and the mixture has a lemony fragrance. Set aside.
Next, in a large bowl, combine the flour, salt, and baking powder. Add in the sugar and zest mixture and whisk until all is combined.
Add eggs, yogurt, vanilla extract, and lemon juice in a separate mixing bowl. Stir until all are combined.
Place the blueberries in a separate bowl and toss the berries with the 1/2 tablespoon flour (this will help prevent the blueberries from sinking to the bottom of the pan during baking). Make sure to rinse and dry completely before this step.
