The Butter Did It (Proposed Butter Whodunit Mystery Ad)

We see a whodunit mystery playing out, but with groceries and cooking ingredients come alive as characters, and the inspector is trying to figure out who did various things, like who made the cake so rich and delicious, and who made the icing so rich and thick, and who made the fresh rolls so creamy on top, and after looking at all the suspects (a carton of milk, a sugar bowl, a container of cinnamon, a bag of flower, a stick of butter, etc.), the inspector concludes that: "The butter did it!" (<From the famous line: "The butler did it!")
