Preheat your oven to 350°F (180°C). This is an important step to ensure your pie pizza bakes evenly.

Roll out the pie dough on a floured surface to fit a 12-inch pizza pan. Be sure to fold or flute the edges for a decorative touch.

In a large bowl, mix together the sugar, flour, and cinnamon. Add the apple slices to this mixture and toss to coat them evenly - this helps enhance the flavor of the apples.

Arrange the coated apple slices in a circular pattern on the dough, covering it entirely. This not only looks beautiful but also ensures that each slice has plenty of delicious apple.

In another bowl, combine the flour, brown sugar, oats, cinnamon, and softened butter for the topping. Mix until crumbly, then sprinkle this over the apples. This adds a delightful crunch to your pie pizza.

Bake the Apple Pie Pizza for 35-40 minutes until the apples are tender and the crust is golden brown.

Once out of the oven, drizzle caramel topping or dip over the pizza for that irresistible finish. You can also sprinkle chopped nuts over the caramel for added crunch!

Serve warm, optionally with a scoop of vanilla ice cream for a truly decadent experience.
