I was looking for a treat to bring to my daughter's kindergarten class for the Halloween party, and when I saw these I knew it was love. And it was simple too!
Divide batter into two bowls, and add yellow food coloring to one, and orange to the other. (you'll want to make less yellow than orange, since the yellow layer of candy corn is smaller than the orange layer)
Put white paper liners into muffin tins, and spoon in the yellow batter. Spoon in the orange batter over top. Bake as usual.
When they are cool, make a batch of your favorite butter-cream icing, and just leave it white. (I imagine you could also use store-bought icing if you'd rather) You could just spread it with a knife, but if you pipe it on with a bag and star-tip, you can have a pretty swirl of icing.
Add a candy corn or two, and voila! A perfect cupcake for a children's Halloween party.
