Sakura's Sweet Cooking

Sakura practices in the kitchen with her father for an upcoming home-economics class. Sakura's classmates decide they will bake cakes. The following day, everyone begins making their various cakes, but after leaving them to bake over lunch, they come back to find them to be far too sweet. The next day, everyone starts over and make sure they measure the ingredients correctly. Sakura and Syaoran sense a Clow Card, staying behind over lunch to find it.
