Preheat oven to 400F (convection) with pizza stone in middle.
In the kitchen-aid bowl, combine the dry (flour, baking powder and salt) and whisk well.
Add the yogurt and mix with a spatula until somewhat combined.
With the dough hook, mix starting at low (1) working up to medium low (3) over about one minute. Continue on medium low (3) for about 5 minutes.
Remove bowl to scrape bottom of remaining dry ingredients and mix for 2 more minutes on medium low (3).
Tidy the dough in the bowl with spatula (clean bowl sides and make top of dough smoothish) then dust with flour. Tilt bowl to one side, scrape that side, and dust with flour. Repeat until dough doesn’t stick to the bowl (give in a whirl around to finish getting a good flour coating).
Flour the counter and dump out the dough. Roll into a log about 4” diameter and cut into 4 equal portions. Flour the cut ends and set 3 aside.
Roll out with rolling pin, flouring both sides frequently.
Dust the pizza peel with corn meal and transfer dough to that.
Spread out 3 spoonfuls of sauce, then add toppings and cheese.
Drizzle olive oil on the crust and spread with your finger. Sprinkle kosher salt on the crust to taste.
Bake 12-14 mins.
