1. Pre-heat oven to 400 degrees Fahrenheit. Remove pizza dough from refrigerator and if not already flattened, use a rolling pin to roll out to form a thin crust. Let pizza crust sit until room temperature while you prepare the remainder of pizza.

2. Use a spiralizer to slice the apples into thin slices (the large blade works best). If you don't have a spiralizer can cut into think slices.

3. In a medium saucepan melt 1 tbsp butter, apple slices, 1/2 tsp cinnamon, 2 tbsp brown sugar. Cook until apples are soft and a gooey sauce forms on apples.

5. Spray a pizza pan or cookie tray with non-stick cooking spray. Place pizza on tray. Cook pizza crust for about 5 minutes.

6. While pizza crust is cooking prepare the crumb. Cut butter into small cubes, mix in 2 tbsp brown sugar, flour, oats, pinch of salt, and pinch of cinnamon. Mix together with a fork (may need to mash together with a fork) and using hands pinch together.

7. Remove pizza crust from oven. Top with apples and then crumb topping. Bake for another 5-10 minutes until slightly browned.

8.  While pizza is cooling mix powdered sugar and water until well combined. Spoon into a small ziploc bag. Cut a small corner of bag to create a pastry bag.  Drizzle glaze over pizza.
