Crumble leftover cake or cupcakes into fine crumbs in a large mixing bowl. Gradually add frosting until fully combined.

Pack the cake mixture tightly into the cakesicle molds, smoothing the tops for an even finish.

Insert wooden sticks into the center of each filled mold and freeze for at least 1-2 hours.

Melt the coating chocolate or candy melts in a microwave-safe bowl, stirring until smooth.

Remove the frozen cakesicles from the molds and dip each one in the melted chocolate, ensuring full coverage.

Before the chocolate sets, add colorful decorations and let them cool on a parchment-lined baking sheet.

Refrigerate the decorated cakesicles for about 30 minutes until the chocolate coating is firm.
