Preheat an oven with a pizza stone to 550 degrees F, if possible. If your oven does not go up to 550 degrees F, preheat it to the highest temperature possible.
In a bowl, mix cream cheese and sugar together well combined. In a second bowl mix together brown sugar, melted butter, and walnuts.
Roll pizza dough onto a 12-inch pizza screen. Spread an even layer of the cream cheese mixture on top of the dough. Distribute a layer of fruit topping evenly over the cream cheese, if desired. Sprinkle the brown sugar mixture on top of the pizza and bake in oven for 12 minutes. Cut into wedges and serve.
