Abstract: A cake decoration mold assembly includes a collapsible housing that has a bottom wall and a perimeter wall coupled to and extending upwardly from a perimeter edge of the bottom wall. A shaft is positioned on a top edge of the perimeter wall of the collapsible housing such that the shaft extends between a first lateral side and a second lateral side of the perimeter wall of the collapsible housing. The shaft has a shaped cake decoration positioned on the shaft so the shaft may dry the shaped cake decoration. A roller is rollable over the cake decoration so the roller may flatten the cake decoration. A hook may be selectively coupled to the collapsible housing.
