Preheat oven to 350°.
Combine cake mix, heavy whipping cream or half-and-half, oil and eggs in a large mixing bowl with an electric mixer until smooth.
Divide the batter evenly between three bowls.
Leave one bowl white; color one batter with yellow food coloring and one bowl with orange food coloring.
Stir each to combine well.
Line approximately 15 muffin tins with paper liners.
Pour white batter into muffin liners until about ¼ full.
Top with orange batter to the half way point.
Finally, top the orange batter with the yellow batter so that the muffins are about ¾ full of batter.
Bake at 350° for approximately 18-23 minutes or until a toothpick inserted in center comes out clean.
Cool about 10 minutes in pans before removing cupcakes to a baking rack.
Cool completely.
Frost with Candy Corn frosting.
Sprinkle with Candy Corn sprinkles.
Sprinkle about a teaspoon of Halloween sprinkles on top of each cupcake.
Place candy corns on top of each cupcake, if desired.
