You can sprinkle with chopped nuts on top for presentation and Our Lovers of Nuts.
We all have Imaginations,
Use Yours, add your Own topping ideas, over the frosting, Coconut, Nuts, Chocolate Sprinkles, mini choc chips, mini m&m's. etc.

I have used the Hershey's Cocoa Pdr in these if I don't have the bar type Chocolate. But the Bar is Much richer taste.

Note; these are Not Difficult to Make. I had to Edit due to so many Questions. So Hope this all helps and is self Explanitory.
