Method
1.Preheat oven to 180°C. Lightly grease an 18x28cm slab pan and line the base and 2 long sides with baking paper.
2.In a large bowl, using an electric mixer, beat egg-yolks, 1/2 cup sugar and vanilla, until mixture is thick and pale.
3.Sift flour and baking powder together. Fold into egg-yolk mixture alternately with milk, beginning and ending with flour.
4.Using an electric mixer, beat egg-whites until soft peaks form. Add remaining 1/4 cup sugar, one tablespoon at a time, until sugar dissolves and mixture is thick.
5.Lightly fold egg-white mixture into cake mixture. Spoon into prepared pan. Smooth the surface. Bake for 20-25 minutes, until a skewer inserted into the centre comes out clean. Cool in pan for 10 minutes, then place pan in a large, deep baking dish. Use a skewer to pierce holes over the surface of the cake.
6.In a large jug, combine condensed milk, evaporated milk, cream and rum. Slowly pour over the cake. Cover and chill overnight.
7.When ready to serve, in a bowl, using an electric mixer beat extra cream and extra sugar until firm peaks form. Spread over the cake. Cut into squares. Serve topped with mango and mint leaves.
