Preheat the oven to 350 degrees and lightly grease a muffin pan.
In a medium bowl, stir together the flour, shredded coconut, baking powder, baking soda, and salt.
In a large bowl, stir together the eggs, coconut oil, maple syrup, lime zest, and vanilla.
Add the dry ingredients to the wet ingredients and mix to combine well.
Fold in the mango and pineapple.
Transfer the batter to the muffin pan and bake for 15-20 minutes, until a toothpick inserted in the center comes out clean. Don’t leave them in the oven too long or they’ll be dry.
Cool on a wire rack.
