This is a recipe that I found online searching for a recipe that uses everyday ingredients to make a clay for making figures to decorate a cake. I have not tested it yet, but will soon - I will post my results then. If you try it first, please let me know how it worked for you. I noticed in the directions about it being sticky so I am guessing more powered sugar could help along with a bit of refrigeration.
light corn syrup
flavoring extract (vanilla or your choice)
several different paste or gel food colors
1Mix all ingredients except any coloring.
2Determine how many different colors you want and divide the clay into small bowls; one for each color and one for white.
3Mix the individual colors in each bowl to the color intensity that you want.
4Dough gets stickier as you work with it, but hardens a bit when refrigerated. (See my notes above)
5Use the clay to make decorations for your baked items.
6(NOTE: The article I read when I found this recipe stated that the Author had made comic figures, and a playground with landscape. Please let me know how this worked if you try this before I do)
