Here is a version of "pizza hut origial pan pizza" that I came across. Don't ask how I got it or else I'd have to kill ya
I don't know if this is anything close to what you pizza hutters are making or using, so I can't vouch for it's authenticity. I haven't tried it.
Pizza Hut Original Pan Pizza
1 1/3 cups Warm water (105F)
1/4 cup Non-fat dry milk
1/2 teas. Salt
4 cups Flour
1 Tbls. Sugar
1 pk. Dry yeast
2 Tbls. Vegetable oil (for dough)
9 Oz. Vegetable oil (3 oz. per pan)
Butter flavored Pam
Put yeast, sugar, salt, and dry milk in a large (2 qt.) bowl. Add
water and stir to mix well. Allow to sit for two minutes. Add oil
and stir again. Add flour and stir until dough forms and flour is
absorbed. Turn out on to a flat surface and knead for about 10 minutes.
Divide dough into three balls. In three 9" cake pans, put 3 Oz. of
oil in each making sure it is spread evenly. Using a rolling pin,
roll out each dough ball to about a 9" circle. Place in cake pans.
Spray the outter edge of dough with Pam. Cover with a plate. Place
in warm area and allow to rise for 1 to 1 1/2 hours.
