If you want to serve these in mango halves, slice the mango around the pit on both sides and use a spoon to remove the fruit. It took about 4 mangos to get 5 cups of diced mango. Transfer the diced mango to a sheet pan lined with parchment paper and freeze until frozen solid (2-4 hours). Alternatively, you can skip this step and just use store-bought frozen mango.

Add all ingredients to a food processor or blender and blend until completely smooth. This may take a minute or two since the mango is frozen. Stop to scrape down the sides in between blending to make sure everything is incorporated. 

Enjoy right away for a soft serve style, or scoop into mango halves and return to the freezer until set (2-3 hours).
