I have generally only seen Kit-Kat's and Piourette wafers used on the candy barrell cakes. I was looking for some new ideas for a chocolate lovers birthday cake. Hit me with your best stuff!
Chocolate covered reception sticks would be pretty, they have colorful tips that aren't chocolate covered.
Oreo straws? Cadbury chocolate fingers? Those are the first things to come to mind.
I used Twix on one I did.
