Let the dough sit out for about 20 minutes. This makes it soft and easy to stretch. On a floured surface, roll the dough into a circle about 12 inches wide. Move it onto your pan. You can use parchment paper too.
Use your brush to spread the melted butter over the dough. Cover it all the way to the edge. This step helps the crust turn gold. It also gives the topping something to stick to.
In a small bowl, mix the brown sugar, white sugar, and cinnamon. Sprinkle this over the buttered dough. Leave a small edge bare for a crust.
Heat your oven to 425°F. Bake the dough for 12 to 15 minutes. The edges should turn gold. The center should look set. Let it cool on the pan for 5 minutes before you add icing.
In a bowl, beat the cream cheese until smooth. Add the powdered sugar, vanilla, and milk. Whisk it until smooth. It should pour with no lumps.
Drizzle the icing over the warm crust in thin lines. Add chocolate chips or fresh fruit now. The warm crust helps them settle in place.
Let the pizza rest a few minutes. This lets the icing set. Cut it into wedges or squares with a sharp cutter. Serve it warm.
