Preheat your oven to 350ºF.Prepare 12 muffin cups (I use silicone, and they work best without greasing)
Combine the flour, baking soda, salt, and spice (if using) in a medium-sized bowl.Blend the mango puree, honey, oil, and vanilla in a large bowl (if using the “milk” or egg options below, then add them now).Fold the dry ingredients to the wet, along with the diced mango, and stir with a spoon just until combined.Some lumps are okay. You don’t want to overmix or the muffins will be dense.
Bake the muffins for 25 to 30 minutes, or until they begin to brown slightly, pull away from the sides, and a toothpick inserted in a muffin comes out clean.
Drizzle the muffin tops with the tablespoon of honey.
Let the muffins cool for 15 minutes in the cups
Remove the muffins to a wire rack to cool completely.
