Preheat the oven to 400°F and grease a 12-cup muffin tin.
In a medium bowl, combine the whole wheat and almond flours, the baking powder, cinnamon, and salt.
In a large bowl, vigorously whisk together the almond milk, olive oil, eggs, sugar, vanilla, and lemon oil, if using.
Dust the blueberries with ½ teaspoon flour and toss to lightly coat them. This will prevent them from sinking to the bottom of the muffin cups.
Pour the dry ingredients into the wet ingredients and stir to combine. Gently fold in the blueberries. Use a ⅓-cup measuring cup to scoop the batter into the muffin cups. Bake for 17 minutes, or until the muffin tops spring back to the touch.
Notes
*Or a 50/50 mix of all-purpose and whole wheat flour.
