Turn on the oven to 350°F and prep a 9x13-inch pan by lining it with parchment paper that slightly goes up the edges.
02 -
In a mixing bowl, beat the egg yolks with ½ cup sugar, vanilla, and salt until fluffy and pale. Toss in the milk and stir till smooth.
03 -
Sift the flour, cornstarch, and baking powder into the yolk mixture. Gently stir the mix until just combined. Overmixing can make the cake dense, so go easy.
04 -
In a fresh, clean bowl, whip egg whites with cream of tartar until frothy. Slowly add the remaining ¼ cup sugar and continue whipping until you get bright white glossy peaks that hold their shape.
05 -
Take a third of the whipped whites and fold it into the yolk mixture to loosen it. Gently add the rest of the whites to this and fold everything till smooth. Pour into the prepared pan and bake for about 15 minutes, or until a toothpick slides out clean.

When the cake is cooling, throw the mango, yogurt, milk, cardamom, and sugar into a blender and process until super smooth. To remove any leftover fibers, press the blend through a fine strainer. Tweak sweetness to your liking.
07 -
Stir together the condensed milk, evaporated milk, regular milk, and half of your mango lassi blend in a bowl. If this mix feels super thick, add some regular milk to loosen it up.
08 -
After the cake is cool, poke lots of holes using a skewer. Slowly pour about ¼ of your mango-milk mixture over the surface and let it seep. Repeat the process in stages until the mixture is absorbed fully. Refrigerate the cake for a few hours to let it soak up all that mango goodness.
09 -
Whisk the chilled whipping cream in a cold mixing bowl until soft peaks form. Gradually pour in the remaining mango lassi blend and continue whisking until the peaks are thick but still spreadable.

Spread the mango whipped cream generously over the cake. Add a fancy touch with swirls of plain whipped cream and fresh mango slices. Chill and serve cold for the ultimate treat!
