First, you follow an awesome snicker doodle recipe. I use my mum's. It calls for cream of tartar, which for some reason makes it better than all the other recipes that don't.
Mix:
1 cup shortening
1 1/2 cups sugar
2 eggs
then Mix:
2 3/4 cups flour
2 tsp cream of tartar
1 tsp baking soda
1/2 tsp salt
Instead of just rolling little dough balls in cinnamon and sugar, divide all of the dough into several sections on wax paper. Put a few drops of food coloring in each section, and mash it in with your hands til you have several little colored mounds.
Next, take a little pinch of each color to make a mini dough ball.
After you make your dough ball, roll it in a little cinnamon and sugar, and place on a baking sheet.
bake @ 400 degrees
8-10 minutes
Don't they look so yummmy! Husband loved them. I took them to school on St Patty's, and my ESL kids gave me a look like "you want us to eat cookies that look like play-doh?". The brave ones each tried a rainbow cookie, realized they were delicious, and came back for seconds. They were a big success.
