Preheat oven to 400 degrees F. Line a muffin pan with 6 muffin liners.
In a large bowl, whisk together eggs, coconut milk, ghee, lemon juice, lemon zest, and vanilla extract.
In a separate bowl, stir together coconut flour, Swerve, baking powder, and sea salt.
Pour dry ingredients into wet, and stir until just combined. Do not overmix.
Fold in blueberries.
Pour the batter into to the prepared muffin cups.
Bake for 15-20 minutes, until a toothpick inserted into the center comes out clean.
Cool for a few minutes before removing them to cooling rack to finish cooling.
Let the muffins cool completely before removing from the liners to keep them from sticking.
