Begin by crumbling your leftover cake or cupcakes in a large mixing bowl. Mix in enough frosting to bind the crumbs together, creating a dough-like consistency.

Take your cakesicle molds and firmly press the cake mixture into each cavity, distributing it evenly and compactly.

Once your molds are filled, place them in the freezer for about 30 to 60 minutes to firm up.

While the cakesicles chill, prepare your coating chocolate or candy melts according to the package instructions, stirring until smooth.

Carefully remove the chilled cakesicles from the molds and dip each one into the melted chocolate.

Before the chocolate coating sets, decorate with Halloween-themed decorations or contrasting chocolate designs.

Allow the decorated cakesicles to set at room temperature until the chocolate hardens completely.
