Kue Lapis is a classic Indonesian layer cake. Its made out of steamed rice flour dough. The classic flavor is be Pandan for the green layer, coconut milk for the white layer, and chocolate for the brown layer.
Frankly, my mom has never made this cake for one good rational reason: it takes toooo loooong to make, you have to cook layer by layer. She always got it from the market, and it was always good. I think the proper way to eat the cake is you peel a layer and eat it. Biting it right on the cake will be considered impolite, trust me (which you should not). :P
I have been told that this cake can not be preserved for more than a day because of the coconut milk in it but it has never been the case for me tho (yippee!!). Simply put it in a bowl with lid and keep it in the fridge. It will become a bit stiff like a block of eraser but this is not a problem. Reheat it in the microwave for a minute or so and the cake will be soft and gooey as it supposed to.
