Begin by crumbling your leftover cake or cupcakes into a large mixing bowl. Add enough frosting to bind the cake together, mixing until it's well combined and resembles a dough consistency.

Next, firmly pack the cake mixture into your cakesicle molds, filling them to the top for a nice, rounded shape.

Place the molds in the refrigerator to set for at least 30 minutes. You'll know they're ready when the mixture feels solid to the touch.

Melt your coating chocolate or candy melts in a microwave-safe bowl in 30-second intervals, stirring in between, until smooth and fully melted.

Carefully remove the chilled cakesicles from the molds. Dip each one into the melted chocolate, ensuring they are completely coated.

Before the chocolate sets, add your desired decorations such as sprinkles, edible eyes, or festive Halloween-themed adornments.

Let the decorated cakesicles sit until the chocolate hardens completely, about 15-30 minutes. Store any leftovers in an airtight container in the fridge.
