Brazilian Banana Cake

I found it in a Brazilian site and modified it:

Layer the ripe bananas (we used 10 of them) in two layers, between 1/3 of the dry mix at a time, then drizzle with a can of sweet condensed milk and bake!

Dry mix: 1 C flour, 1 C sugar, 3/4 stick soft butter, 1 Tsp Baking powder.

Yum!
