Preheat your oven to 375 degrees F and line a large baking sheet with parchment paper, set aside.
Cream together your butter, sugar and brown sugar until fluffy.
Beat in your egg and vanilla extract until combined.
In a separate bowl, whisk together your flour, baking powder, baking soda, and salt. Slowly mix your dry ingredients into your butter mixture until well combined.
Fold in your chopped mangos.
Using a large 3 tbsp cookie dough scoop, place your cookie dough balls on your prepared baking sheet, leaving a few inches in between for cookies to spread.
Bake for 8-10 minutes or until cookies have JUST started to brown.
Allow to sit for at least 5 minute on baking sheet before transferring to a wire cooling rack to fully cool. Enjoy!
