Preheat oven to 375°. Line a baking sheet with parchment or silicon baking liner.

Prepare mango by pulsing in food processor until small pieces. Set aside. Can also do by hand.
In bowl , mix egg, cream, and vanilla.
In bowl of food processor, mix flour, sugar, baking powder and salt. Pulse a couple times to mix.
Cube the butter and add to food processor. Pulse until combined and butter is cut up into small pea sized pieces.
Add the egg, cream and vanilla mixture to the food processor. Pulse until dough just begins to come together.
Add the mango and white chocolate. Pulse until combined with dough.
On lightly floured surface, bring dough together into an 8 inch round. Cut into 8 - 12 triangles. 8 will yield fairly large scones. Can also be made into a rectangle and will yield 18-20 mini scones. Leave room on the baking sheet - the scones will spread slightly during baking.
Place on baking sheet and bake for 15-20 minutes or until light golden.
Remove from oven and allow to cool on rack.
