Roll pastry to fit a 12-in. pizza pan; fold under or flute the edges. Combine sugar, flour and cinnamon in a bowl. Add apples and toss. Arrange the apples in a single layer in a circular pattern to completely cover pastry. Combine the first five topping ingredients; sprinkle over apples.
Bake at 350Â° for 35-40 minutes or until apples are tender. Remove from the oven and immediately drizzle with caramel topping or dip. Serve warm with ice cream if desired.
