Rainbow Cake Roll

Nancy Geissler said that years ago she saw a cake mix ad for a similar cake. This became the inspiration for her colorful cake roll using a homemade sponge cake. She likes to keep it on-hand in her freezer in the summer. "Besides looking pretty, it's refreshing and it always gets raves," she writes from Pittsburgh, Pennsylvania. 10-15 ServingsPrep: 30 min.
