Measure out all the necessary ingredients. Separate the yolks; we don't need the whites. Wash, peel the mango and cut into slices. Place the oven on preheat.
To prepare, mix all the ingredients for the dough and add 3 tablespoons of water. Wrap in plastic wrap and chill in the refrigerator for 30 minutes. Roll out the dough into a circle with a diameter of 25 cm and a thickness of 4 mm and refrigerate again.
Place the dough in the cooking ring, pressing it against the sides, trim off the excess. Using a fork, prick the dough all over the surface and cover with greaseproof paper; sprinkle beans or cereal on top to prevent the dough from rising. Bake for 25 minutes until golden brown. Then remove and cool.
In a saucepan, beat the egg yolks with sugar and cornmeal, at the same time pour in hot milk and cook until thickened. Remove from heat, add vanilla extract, butter and cool in the refrigerator.
Remove the cream from the refrigerator and combine with the whipped cream. Coat the cake with cream and arrange the mango slices.
Cut the cake into triangles, sprinkle with powdered sugar and serve.
