Preheat oven to 350F and line 8 muffin cups with paper liners.
Make the muffin batter:
In a food processor, combine flax meal, walnuts, and coconut flour until it resembles coarse sand. Add baking soda, salt, and cinnamon; pulse a few times to combine.
Add raisins and pulse, until they are chopped and incorporated into mixture (you are not trying to make a paste, just a coarse dough of sorts).
Add eggs and melted coconut oil and pulse a few times to incorporate. Fold in grated carrot just to combine.
Bake:
Spoon in about ¼ cup of muffin batter into prepared muffin cups. Bake 22 minutes, or until toothpick comes out clean. Allow muffins to cool for 45 minutes prior to eating.
Notes
Allergy-Friendly: substitute ¼ cup walnuts with ¼ cup sunflower seeds + 1 teaspoon additional melted coconut oil.
