Peel mangos. Cut the fruit lengthwise away from the seed in quarters. Then slice the quarter pieces in half (lengthwise). Place equal parts mango in 4 (oven safe) dessert dishes.
Pre-heat oven to 325°F. Adjust oven grill to highest setting.
Split the vanilla bean lengthwise with a sharp tipped knife and scrape the tiny black seeds out of the bean into a small dish and set aside.
Mix egg yolks and sugar cane in separate bowl until the mixture appears white in color. Add cream and vanilla. Pour this mixture over the mango slices.
Put in the oven and let cook approximately 5-7 minutes (or until the desserts take on a nice golden color)
