Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners.
In a large mixing bowl, combine the almond flour, coconut flour, baking soda, cinnamon, nutmeg, and salt.
In another bowl, whisk together the eggs, maple syrup, and melted coconut oil.
Pour the wet ingredients into the dry ingredients and mix until well combined.
Fold in the grated carrots.
Divide the batter evenly among the muffin cups.
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 tin for 5 minutes, then transfer to a wire rack to cool completely.
