First you need a twinkie pan. And I mean NEED a twinkie pan. Doesn't everyone?
I made my cake from scratch but a cake mix would work fine. I also overfilled the cups so I had to trim off the bottoms so they could stand straight.
Instead of pudding, I used premade custard from our local amish bulk food store. It is really good!
I then melted a combination of dark chocolate candy melts and fondue chocolate. Holding the cakes firmly, I dipped them into the chocolate and lthen sat them on wax paper.
