Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or lightly grease it.
In a large bowl, mix together the almond flour, erythritol, baking powder, and salt.
In another bowl, combine the almond milk, melted coconut oil, flax egg, and vanilla extract.
Add the wet ingredients to the dry ingredients and stir until just combined. Gently fold in the blueberries.
Divide the batter evenly among the muffin cups, filling each about 2/3 full.
Bake for 20-25 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
