The secret to getting that wonderfully airy sponge lies in beating your eggs and sugar thoroughly so it can drink up all that rich milk. Give it a solid five minutes with your mixer, and take extra care when gently folding in the flour so you don't knock out the air. You'll want to make sure your baked cake cools down completely before drizzling over the warm milk, which guarantees an even, beautiful soak without turning soggy.
For that dreamy topping, you'll begin with a simple cooked custard on the stove. Keep stirring until the flour and cornstarch bubble into a thick, glossy base with no raw starchiness left behind, then let it chill out before whipping in the dry whipped cream powder for a light, cloud-like texture. Smooth it over your soaked cake, then shower the top with plenty of shredded coconut.
The beauty of this dessert is that most of the work is just waiting while it chills in the fridge. Tuck the finished cake into the refrigerator for at least 3 to 4 hours - or honestly, overnight if you can wait - which sets the custard nicely and gives you those picture-perfect, clean slices.
