We used chocolate cake mix (it was what we had on hand), chocolate candy melts, white candy melts, Good 'n Plenty candy for ears, white spice drops for bunny tails, and frosting pens for the face. We chose to make cake pop "truffles" because we thought it would be a little be easier to transport to Easter lunch (and they fit nicely in a glass dish). We did try one "pop" on a stick, but it promptly fell apart, so we stuck with the original game plan of not using sticks. One tip I would pass along to anyone who wants to try this is to use a light colored cake mix if you are going to use a light colored candy melt to dip the pops in (otherwise, you'll see the dark cake through the light colored coating).
