Preheat oven to 350 degrees F.

In large bowl, mix together sugar, vanilla, eggs, oil, lemon juice, and milk. In a separate bowl, combine flour, baking salt, baking powder, and baking soda.  Stir into liquid mixture, until just combined.

Your batter will be lumpy and that's okay!

Fold in zucchini, blueberries, and lemon zest. Spray muffin tin with non-stick cooking spray.

Fill each tin ¾ths of the way full with batter.

Bake for 12-15 minutes, or until a toothpick inserted in the center comes out clean.
