Catherine Niblack, the "cake lady" of Duncanville, was born in Sweden into a line of famous bakers. An uncle, she says, baked for the king, whose favorite treat was the uncle's mocha cake. The uncle later came to California and baked for Hilton Hotels. He left behind a book of recipes that Niblack still uses. Her cakes, baked in her home kitchen at the rate of one per week, are the stuff of legend among people lucky enough to see and taste them at area weddings. The serving slices are twice the size offered by most bakeries, at $2.50 a slice for wedding cakes and $3 for groom cakes, still based on the king's mocha in many cases. The number above is her home phone, and she can be called during "normal business hours." Appointments can be made to see pictures of her work. There have been occasions when her cake was the only thing at the wedding party that guests remembered years later.
