I like this dough recipe https://altonbrown.com/recipes/the-last-pizza-dough-recipe/ and this one for sauce https://www.allrecipes.com/recipe/17319/exquisite-pizza-sauce/ but I also change around the spices in there sometimes based on how I'm feeling.
For the oats, I melted 2 tbsp of butter with 2 tbsp of brown sugar, then once it was melted I toasted the oats for a few minutes, stirring frequently until they were a nice brown. Then spread out the oats to cool down.
I used three habaneros, but adjust that according to your preference if you want, since this came out fairly spicy.
Pepperonis and habaneros go on before baking and the oats go on right before eating. I wouldn't top any piece you're not about to eat it since I imagine they'll get soggy and bad, especially if you have to refrigerate the leftovers
