Preheat oven to 350°F (175°C) and line a muffin tin with 6 paper liners.
In a medium mixing bowl, whisk together the eggs, melted coconut oil, maple syrup, and vanilla extract until emulsified.
Incorporate the coconut flour, baking soda, and salt into the wet mixture, stirring until no lumps remain.
Let the batter rest for 5 minutes to allow the coconut flour to fully hydrate and thicken.
Gently fold the fresh blueberries into the thickened batter using a spatula.
Distribute the batter evenly among the 6 muffin liners, filling each approximately three-quarters full.
Bake for 20 to 25 minutes until the tops are firm to the touch and a toothpick inserted into the center comes out clean.
Allow muffins to cool in the pan for 10 minutes before transferring to a wire rack for final cooling.
