Combine dry ingredients in a mixing bowl, slowly add the water, whisking until ingredients are well combined.
Gently mix the dough with your hands until a ball is formed.
Cover bowl with plastic wrap, allowing the dough to rest at room temperature for around 18 hours, or until roughly doubled in size.
Once dough has rested, cut into three portions. On a floured worked surface, gather four corners to the center of the dough, creating four folds.
Place seam side down, gently form dough into a ball, dust with flour, wrap in plastic, or cover with damp towel and let rest for 1 hour. If storing in the fridge, lightly coat ball of dough with oil, and wrap in plastic wrap, taking dough out of the fridge at least an hour before using for pizza.
Before cooking the pizza, turn oven to its hottest setting (~500F), allowing to preheat for one hour. If using a pizza stone, place it in the oven before preheating.
To form the discs, flour whatever surface you will be transferring the pizza into the oven with (I use a large pizza paddle).
Using the back of your hands, gently stretch the dough into 10-12 inch discs.
Place toppings on pizza.
If using pizza stone, place pizza on the stone, turning the oven to broil, and cook for 5-7 minutes until pizza is cooked to your liking.
If you don't have a pizza stone, place pizza on a floured baking sheet, cooking for about 10 minutes on the ovens hottest setting.
If you want to put pumpkin on the pizza, using a vegetable peeler, peel away the pumpkin to create thin ribbons, Once you have enough ribbons to moderately cover the top of your pizza, brush them with a little bit of melted butter, and sprinkle with some cinnamon sugar, and pumpkin pie spice.
Once pizza dough is formed, brush about 2 tablespoons of melted butter onto the dough, then sprinkle cinnamon sugar onto the dough.
Spread a layer of spiced pumpkin mix onto the dough, followed by the ribbons of pumpkin, as well as a generous drizzle of sweetened condensed milk.
Following instructions above, bake in the oven until done.
Once pizza is cooked, and cooled slightly, drizzle with more sweetened condensed milk (to your desired sweetness), then top with ice cream, or whipped cream if you would like, and enjoy!
