In a large stand mixer, combine the yeast, sugar, salt, water, olive oil, and bread flour.
Knead the dough with the dough hook for 6-8 minutes, or until a soft dough ball is formed.
Remove the dough hook, cover, and allow to rise for 1-2 hours.
Filling and Braiding
Preheat the oven to 400℉.
Punch down the dough and remove from the bowl.
On a large work surface, roll the dough to a 20x14 inch rectangle.
Using a sharp knife, cut slits down both sides of the longer side of the dough, leaving about 6 inches in the middle to add the cheese and pepperoni.
Sprinkle the mozzarella, pepperoni, and 1/4 cup of parmesan cheese over the entire length of middle of the dough.
Fold one end of the dough over the filling and begin braiding the dough from one side to the other. Stretch the dough pieces completely to the other side of the roll.
Once the dough is braided to the end, tuck the end dough under the last braid.
Brush the entire dough with egg wash, sprinkle pizza seasoning and parmesan cheese on the top and bake for 20 minutes.
Remove the pizza braid to a cooling rack and allow to cool for at least 15 minutes before slicing and serving.
