Preheat oven to 350°. On a lightly floured surface, roll dough to fit a 12-in. pizza pan; fold under or flute edge. Combine sugar, flour and cinnamon in a bowl. Add apples and toss. Arrange apples in a single layer in a circular pattern to completely cover crust. Combine the first 5 topping ingredients; sprinkle over apples.
Bake until apples are tender, 35-40 minutes. Remove from the oven and immediately drizzle with caramel topping or dip. Serve warm with ice cream if desired.
