Preheat oven to 350 degrees. Line a 9 x 5" loaf pan with parchment paper. (To help secure the paper, it is helpful to use binder clips to prevent the paper from slipping when adding the batter. Just remember to remove the binder clips before baking.) Set prepared pan aside.
To a large mixing bowl, add the dry ingredients: 2 c. of flour (reserving 2 tbsp. to coat the blueberries), sweetener, baking powder, baking soda and salt. Use a whisk to mix together.
To the dry ingredients, add the wet ingredients; Greek yogurt, milk, eggs, coconut oil, lemon juice and lemon zest. Whisk together well until combined and smooth.
In a separate bowl, and the blueberries. Sprinkle with the remaining 2 tbsp of flour to coat the berries. Add in the coated blueberries and gently fold into the batter.
Pour the batter into the prepared loaf pan, and bake for 55-58 minutes or until a toothpick inserted into the center of the loaf comes out clean and crumb-free.
Let the loaf cool to room temperature. Using the parchment paper, lift the loaf from the pan, and remove the paper - it should easily peel away from the loaf.
Lemon glaze: to a bowl, add the Swerve and lemon juice. Mix together with a spoon until smooth and slightly thick. Drizzle over the top of the cooled loaf. Garnish with additional lemon slices, lemon zest or fresh blueberries if desired. Slice and enjoy.
