BANANA CAKE

1. In a bowl, put the chopped bananas.  We crush it with a fork until we get a kind of puree.  We reserve this puree that will be the base of our banana cake.
2. In another bowl, we put the eggs and beat them with a rod until they double their size.  Then we add the essence of vanilla, sugar, milk, a pinch of salt and butter, which we will have previously melted in the microwave.  Beat again until all the ingredients are integrated.
