Scrumptious Smackeroodles are cookies that Muffy comes up with for the Strawberry Festival baking contest in "How the Cookie Crumbles." Originally, she takes credit for the cookies instead of allowing her friends to share the fame, but feels guilty and not only gives them proper credit, but adds them to the bag design. The cookies are sold in the Sugar Bowl.
The Scrumptious Smackeroodles reappear in "The Ballad of Buster Baxter." Buster sees the cookies and feels that he has been left out.
