My son loves golf and wanted a golf themed cake for his 6th birthday. My first attempt. So, next time I will know what to do differently. But, I used gelatin gel I made and colored it blue for the water. I used fondant for the pebbles/rocks. One of the trees is an ice cream cone covered in a crusting buttercream. Not shown, I made a small golf ball out of fondant and placed it by the hole. The sand pit is made of graham crackers.
