Hasty Pastry Bakery  is a company specializing in various baked goods such as cakes and pies.
The Hasty Pastry Bakery factory was used by Imps to play a prank on the Ghostbusters. They called the Ghostbusters and placed a false call to the factory. Once the Ghostbusters arrived, the Imps inflated a giant frog water balloon and then messed with the assembly line control panel. The factory, as a result, was covered in pies and cakes. Peter Venkman shut off the machinery but the balloon falsely implicated Ray Stantz since he was the new owner of the Gaylord's Joke Shop.
