I have a small home cake pop business.  I normally make my cake pops very smooth, and have someone who has requested something like these.  How do you suggest doing the blue top part?  It looks like it was spread with a knife, but it would be hard to do that with candy melts.

AThe blue looks like frosting a little bit IMO. Either that or it would just be the patience of doing layer after layer of candy melts. HTH

Looks like it was done with a squeeze bottle after the pops were dipped.

I also think it was spread on with a small knife.  It wouldn't be difficult to do as long as you let the melts cool down quite a bit so they aren't runny.
 

AYou can also use a toothpick to dab/spread thick chocolate/candy melts & top with sprinkles. It will dry quickly. Toothpicks are my best friend! Lol!

Yeah or just put the thickened melts in a bag, pipe it on around the stick, then use your toothpick or small spatula to swirl it around.  I don't think it would take that much time at all.

Cute idea
