This is a dessert pizza that is delicious!
Most Brazilian pizzarias serve this as a dessert pizza- on top of a thin crust Neapolitan or NY style crust. The secret is to use ripe bananas, and slice them in half, so they cook faster. You can pour the sweetened condensed milk on the crust, and then place the bananas on top of the milk, or put the bananas first, then pour on the milk.
