I made this cake for a last day of school party at my school. The sky is made with sky blue MM fondant. There is a trick I used to get that color swirl. When you knead the coloring in, do not knead it completely. The sun is made with yellow colored buttercream. The sand is made by laying more buttercream over the layer that is used to stick the MMF and sprinkling cinnamon sugar. Enjoy!
