cake pop fail

I attempted to make cake pops for hubby's birthday this weekend.  I had some wonderful ones at the preschool Easter party (thanks Melissa!) and wanted more.  I say I attempted making them because they did not really work well. 

You just make a cake and mix it and the icing in a bowl.  You form them into balls and then dip them into melting chocolates.  I used almond bark.  Most ended like this.

But they tasted good.  Then we got belly aches.  I don't know what happened.
