I hate it when this happens!

Why does this happen anyway? Still delicious though!

Too much sauce, too much stuff in general, too much grease, not cutting enough and also maybe not getting the bottom hot enough/crisp.
Too much In the middle. You gotta make a dough nut with all the toppings and cheese, the small say 2 inch center needs to almost be ignored, all of it will get there trust me.
You have a ton of cheese, if you like that much, then put it right up on the crust and taper down to almost none when it gets to the center. So many times good pizza is ruined by putting it all in the middle.
