Ooni Apple Crisp Dessert Pizza

Dough:

1. Proof the yeast by adding the active dry yeast to the warm water and stirring vigorously. The yeast should foam. If the yeast clumps and floats on top of the water it is dead and you need new yeast.
2. Add the flour and salt to a stand mixer with a dough hook and add the cold water. Mix slowly for 1 minute then add the warm water and yeast. Mix for about 1 minute on low, then stop and scrape the sides of the bowl.
3. By hand or using a stand mixer with a dough hook, knead the dough for about 5 minutes until the dough is smooth. Depending on environmental conditions, you may need to add a little more flour or water to the mixture. (The dough should not be dry or too sticky. You should be able to gently pinch the surface of the dough without it sticking to your fingers.)
4. Place the dough ball on a plate and cover with a damp towel. Let the dough sit at room temperature for 1 hour.
5. After 1 hour, uncover the dough ball and divide in half. Form each dough ball by gently stretching the dough and folding the stretched dough to the bottom of the ball. Rotate the ball 90 degrees and repeat. Repeat this process about 5-6 times finishing by pinching together the bottom of the ball. The surface of the dough should be smooth and not torn. Repeat with the 2nd dough ball. Cover with plastic wrap and let rise for 2-3 hours, until doubled.

Toppings

1. Combine the cinnamon and sugar in a small bowl and mix to combine.
2. Mix the oats with 2 tablespoons of melted butter and mix to combine.
3. Mix the powdered sugar, vanilla extract and milk in a small bowl then put in a small plastic bag or a piping bag.

Baking the Pizza

1. Preheat your oven with the Cooking Steel or pizza stone to 425 degrees. If using a pizza oven, preheat to 450-550 degrees.
2. On a well-floured surface hand stretch the dough into a roughly 12-14-inch circle.
3. Place the pizza dough on a floured pizza peel. Baste the dough with 1-2 tablespoons of the melted butter.
4. Sprinkle the buttered dough with the cinnamon sugar then top about ½-⅔ of a cup of the apple sauce. Next top with half of the sliced apples and half of the oats.
5. Pizza Oven: Launch the dessert pizza into the pizza oven and cook for about 5-6 minutes, rotating the pizza about every 1-2 minutes to ensure even cooking., and ensure the bottom of the pizza is not getting over cooked.
6. Home Oven: Slide the dessert pizza into the oven and cook for about 5 minutes. Rotate the pizza 180 degrees and cook an additional 3-5 minutes, until the pizza is cooked to your desired doneness.
7. Remove the pizza to a cutting board and top with half of the icing.
8. Cut into slices and serve warm.
