I forgot about these until I downloaded the pictures from my camera. I tried two different methods for making candy corn cookies - layering the dough and then cutting slices and then triangles - and this method (which I prefer). Just make sure you put the colors in the right order.... oops :)
-Sugar and Spice and Everything Iced
Divide your favorite sugar cookie dough and color - you'll want the majority of the dough yellow (not orange like above! :), then orange and then just a bit for the white.
Roll out your yellow dough and use bowls or large cookie cutters to cut your outside ring, and remove the center circle. Then roll and cut a ring of orange, remove that center circle and place inside the yellow ring. Then roll and cut a circle of white to fit in the middle. Gently press the edges together and score your cookies with a bench scraper or pizza cutter (be careful if you're using a Silpat).
I left mine together as a big circle, so it took quite a bit longer than my normal sugar cookies to bake. Once they come out of the oven, cut through the lines again and let the cookies cool completely before separating.
