Sherry Messersmith, 29, of Chambersburg, combined the pumpkin, eggs, milk, sugar and seasonings in a giant mixer. Each batch fills a five-gallon bucket.
The dough is made by hand, although a machine presses it into pie plates.
Louisa Bair of Chambersburg, who works in the bakery with Goshorn, said she always buys Goshorn's pies.
"I won't make my own at home any more," Bair said. "She just gives it that tender, loving care."
Goshorn confessed that she doesn't have a special recipe. She just uses the one on the six-pound pumpkin can.
Donna Zullinger of St. Thomas, Pa., bought a pumpkin pie and a coconut cream pie Wednesday because she didn't have time to bake. Those are her husband's favorites.
"He knows the difference. Mine's not as good-looking as theirs," Zullinger said.
Martha Gordon, 30, of Shippensburg, Pa., bought four pumpkin and two pecan pies to share with family members.
Gordon made her Thanksgiving dinner on Wednesday because she has to work at the Cracker Barrel Restaurant in Chambersburg today.
On a normal day at Sunnyway, Goshorn makes 10 pies and other assorted cakes and cookies.
She said she doesn't do much baking at home.
"I don't have the time, or the desire," she said.
Goshorn, 43, does plan to make a turkey with the trimmings for her family today. She's expecting to host two of her four children and one of her grandsons.
Even then, the holiday rush is far from over.
"Now all I have to do is get through Christmas," she said. "Nobody bakes cookies at home, believe me. They all get 'em here."
