Sakura's Sweet Cooking - S1.E29

Sakura practices in the kitchen with her father for an upcoming home-economics class, as Sakura is worried about how she will do. Sakura's classmates decide which cakes they will bake. 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, and afterwards everyone except them exits the classroom. They discover it to be the Sweet card, which flies around the room turning everything into sweets and confections. Sakura captures the card after throwing salt on it to temporarily immobilize it, which causes the room to revert back to normal. After everyone comes back, and the cakes have turned out great, except for Meilin's, who made hers too hard.
