If you're really wanting to make these, I suggest going to Martha Stewart's website and watching the video on it. The red velvet cake with cream cheese frosting is divine. Tips: Cook the cake thoroughly - I think better to have it completely cooked and not so moist. I would also use colored candy melts instead of almond bark next time (because when you add the food coloring liquid, it changes the consistency and makes dipping more difficult...)
I believe that you can see the tutorial on Bakerella.com. or here.
