Baking is done one or two days a week, depending on the season. The nuns then sell the cheesecakes online and deliver to some local stores.
"Everything in moderation is one of the Christian concepts, I think," said Sister Cecelia. "So who's to say we shouldn't appreciate food? God made us to love food."
