Bake the cake mix as per box instructions.
Cool the cake completely! Place in a large bowl and using a fork or your hands crumble the cake into pieces.
Mix in the frosting a heaping tablespoon at a time into the crumbled cake. You may not need all of the frosting. The cake crumbs should be the consistency of play dough. Adding too much frosting will make the cake pops mushy and they won't hold together and stay on the cake pop stick.
Chill the dough for about 30 minutes, the cake rolls into balls easier when it is cold.
Use a medium cookie scoop to form even-sized balls. Gently roll the dough between the palms of your hands to make round, even balls. Place the cake balls on a cookie sheet that is lined with wax paper or parchment paper.
Melt about a half cup of the white chocolate using the microwave or double boiler.
Dip the tip of the lollipop stick into the melted chocolate, next insert it into the cake balls. Be sure to insert the stick about halfway into the ball.
Refrigerate the cake balls for about 1 hour to firm up on the stick.
Melt the remaining chocolate in microwave or double boiler.
Dip the cake ball into the chocolate by holding the lollipop stick and rotating until covered. Once covered remove and softly tap and rotate until the excess chocolate falls off. Don’t tap too hard or the cake ball will fall off the stick!
Immediately sprinkle with the confetti sprinkles. If the chocolate dries the candy sprinkles won't stick!
Place the cake pops into a cake pop holder or soft styrofoam block. They can be put back onto the cookie sheet, but the tops will flatten a bit.
Refrigerate until the chocolate hardens.
