These are made from 3 different sized bundt pans. One regular size, then I think the next size down. I used that 2nd size and didn't fill it as full for the 3rd tier, and I also cut out a piece to make it smaller in diameter. If you had a smaller bundt pan than the 2nd layer then it would be easier. The 4th layer is a personal size bundt pan. I covered the cakes with 3 colors of thick glaze to look like flowing lava, and green tinted coconut as grass at the bottom.
