Prepare and bake cake mix and let cool. Grind the cake with your hands or in a food processor to form very fine crumbs.
Mix the crumbs with 1¾ cups prepared frosting in a bowl until it forms a sticky dough. Roll mixture into 1-inch balls and freeze for 15 min.
Dip lollipop sticks in melted chocolate and stick each one into a cake ball. Freeze 20 min more. Dip the pops in melted candy melts and decorate with chopped nuts, dried fruit or sprinkles.
Notes
Any nuts or seeds will do, but the green pepitas are the cutest; and white speckles of coconut are quite tasty. I don't need to tell you crushed cookies are a great topper. You know that!
