Preheat the oven to 350. Line a muffin tray with 12 muffin liners.
In a large mixing bowl, stir together the almond flour, monkfruit sweetener, baking powder, and salt.
Add the melted coconut oil, almond milk, eggs, vanilla extract, and lemon zest. Stir to combine.
Gently fold in the blueberries.
Divide the batter into the muffin cups. Bake for 27 minutes or until the tops are golden and the muffins are cooked through (if a toothpick inserted into the center of the muffin comes out clean, they are ready).
