Checkered cake pans have been sitting on my shelf for two years...finally put them to use. Turned out much better than expected and wow'ed the crowd at work. Used a doctored cake mix recipe (went easy as I had to make two batters), creamcheese frosting. Cirlces are made from piped white and dark chocolate. Tried to make chocolate swirls that could stand up for the center but they didn't have enough time to set and they disintegrated in my hands.
