Mary's cookie sales at Brenda's school is putting Ed's Cookies out of business. He proposes that she go into business with him. They agree, but when Mary realizes that she isn't making more than she was when she was alone, she pulls out of the deal. Ed comes by the next day and offers Mary $15,000 for the recipe. She eventually sells it, but not before Lester comes in and shows her a headline that reads, Big Company to buy cookie recipe from local baker for $100,000. Mary devises a plan to get the recipe back. Before Ed can sell the recipe, she comes in with Sandra dressed as a nun and tells the buyer that the recipe actually belongs to ""Sister Sandra."" He doesn't want to cheat the convent out of their money so he decides not to buy from Sandra. Mary later finds out that her grandmother's cookie recipe is actually Famous Amos' recipe. (thetvdb.com)
