Make the pizza dough. Preheat the oven to 450° F. If using a baking stone or tiles, place in the oven now.
Roll out the pizza dough and spread the ricotta over it. Lay the banana slices on top in concentric circles. Brush the butter over the bananas.
Transfer to the oven and bake for 10 minutes. Remove from the oven and cover with the ham slices. Quickly return to the oven, reduce the temperature to 400° F and bake until the crust is golden, about 10 minutes.
