Dad's Dessert Dillemma is the second part of the seventh episode of Arthur season 3. It aired with the episode Arthur Rides the Bandwagon.
Arthur brings a cake his dad made to a party in Mr. Ratburn's class celebrating Galileo's birthday. Everyone gives positive feedback about the cake so Arthur asks his dad to make more, but this makes his dad run behind on his other orders. A subplot has Mr. Ratburn attempting to get Dad's cake by pretending to try to give anyone who is having cake a schedule of Spring Reading, but his final attempt does not work when it turns out that Arthur and dad are not having cake; they are making cakes for other people.
