Add all ingredients to a high powered blender and… blend! Taste and if desired, add a little more tequila or a little simple syrup – whatever you need. I like to blend without the simple syrup and then taste and add it if the mango is not sweet enough.
Spoon the frosty into cups and serve with lime wedges. Sprinkle with chili powder if you’d like!
If your mango isn’t sweet enough, add a few tablespoons of simple syrup! To make the syrup, heat 1/2 cup sugar and 1/2 cup water over medium heat, whisking until the sugar dissolves. Bring to a boil then turn off the heat and let cool to room temp.
