Preheat oven to 375 degrees F. Spray a 12 cup muffin tin with non-stick baking spray or line with paper liners.
In a medium-sized bowl, combine the coconut milk and lime juice.
In another medium bowl, whisk together the flour, coconut sugar, baking powder, and salt.
Add the milk mixture, lime zest, and vanilla to the dry ingredients and whisk until blended and smooth. Scrape the sides and bottom of the bowl with a spatula.
With a measuring cup, divide the batter evenly between the muffin tin, about ⅔ of the way full each.
Bake in the preheated oven for 14-16 minutes or until a toothpick inserted in the center of muffins comes out clean.
Cool 5 minutes in a muffin pan. Then move to a wire rack to finish cooling.
Notes
Store the cooled muffins in an airtight container at room temperature for 2 days, the refrigerator for 1 week, or the freezer for up to 3 months.
If using low fat or nonfat non-dairy milk in place of the coconut milk, add 3 tablespoons of coconut oil.
