For the cake dough,beat the white eggs to firm snow.

While mixing, add the egg yolks (one by one) and then the sugar.

Bring the milk with the butter to boil.

Add the milk with butter to the bowl of the dough alternating with the all-purpose flour.

Mix until combine all the ingredients.

Add the baking powder and mix.

Bake in a greased cake pan in a pre-heated oven to 356ºF (185ºC) for about 30-40 minutes until golden. (You may use 2 small cake pans or a medium one)

While the cake is baking,prepare the filling:

In a medium pan on medium heat, add all the ingredients besides the chantininho and stir until thick. (About 10-15 minutes).

When thick, let it cool and only mix with the chantininho when filling the cake.

With the cake baked and cooled, unmold from the baking pan and cut the cake in half twice. In the same baking pan, cover the bottom with parchment paper and follow this order: place 1 layer of the cake, soak with the soda (4-6 spoons), fill with the 4 milk filling mixed with chantininho, add another layer of cake, soak with soda, fill with the 4 milk filling and cover with the last layer of the cake.

Place the cake in the fridge for about 8 hours. I like to let it there overnight to firm the filling. (If you're in a hurry put it 1-2 hours in the freezer).

After that time, unmold the cake and place in a cake plate.

Prepare the chantininho. You will find the recipe here. 

Frost the cake with the chantininho. That's it!
