Preheat the oven to 350°F (175°C). Grease and flour a round cake pan. Prepare the cake mix as per package instructions and bake for 25-30 minutes until a toothpick inserted comes out clean.

Allow the cake to cool completely in the pan before transferring it to a bowl. Crumble the cooled cake into fine pieces.

Mix in half of the buttercream frosting until well combined; the mixture should hold together but not be overly sticky.

Roll small portions of the mixture into balls (about 1 inch in diameter) and place them on a lined baking sheet.

Chill the balls in the refrigerator for about an hour to firm up.

Melt candy melts according to package instructions. Dip one end of each lollipop stick into melted candy and insert it halfway into each ball, then coat each ball entirely before placing it back on parchment paper.

Allow the coating to set before serving or displaying.
