Preheat oven to 375°F (190°C) and grease or line a 12-cup muffin tin.
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
In a separate medium bowl, combine the almond milk, oil, and vanilla extract.
Pour the wet ingredients into the dry ingredients and stir until just combined, being careful not to overmix.
Gently fold in the fresh blueberries and lemon zest.
Divide the batter evenly among the 12 muffin cups.
Bake for 22 to 25 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack.
