Shake the yellows, with the sugar until they double the size.
Add the flour, with the baking soda.
Add the warm milk.
Shake the whites until they get big, in spanish we say stir until they get like turron, the turron is a very very hard candy, so you need to shake them until they get like very very fluffy, if you use a machine let it go for a long long time.
Add the whites to the other stuff, and mix it well.
Put that in a mold, and put in the oven for 25 minutes.
let it go cold.
In the blender put the"tres leches ingredients", and blend them until they mix really good.
Then put this mix over your cake, but let the cake absorb the mix, so I recomend to put this mix inside the mold with the cake, so it will really abosorb, let it like that for 1 hour and then take it out, add some whipe cream, and some cherrys to make it look wonderfull, AND ENJOY!
