Arthur enters a cooking competition at school, hosted by famous chef, Ming Tsai, with plans to make a chocolate cake. His dad insists on wanting to help, even thought it's a Kids-only competition. But when Arthur makes a mistake, adding baking soda instead of baking powder, he learns that many great foods were created by accident. Meanwhile, Arthur, Muffy and the others are also worried about the type of judge Ming will be.
