I figured I'd make as many as I could and then give some to each teacher in the school that had asked me to teach in their classroom more than once. As it turned out my kids' teachers also had used me as a substitute in their class so they got a double whammy.
I can't beat Bakerella's instructions so I think you should just follow her teachings. The only thing I did different is that I went with different flavorings.
I will fully and readily own that I need to work on my dipping technique. I used a double boiler to melt the chocolate and that was overkill. I got much better results with the microwave method melting just enough at a time. The other thing that helped was to keep the cake balls frozen so that they didn't crumble in the chocolate.
