Remove paper baking cups. Cut each cupcake in half horizontally. In each jar, place 1 yellow cupcake half and 1 orange cupcake half. Spoon 1 container of frosting into 1-gallon resealable food-storage plastic bag; seal bag. Cut off about 1/2-inch corner of bag. Twist bag above frosting; squeeze bag to pipe frosting over orange cupcake in each jar. Sprinkle evenly with 1 cup of the candy corn. Repeat layers with remaining cupcake halves, second container of frosting and remaining 1/2 cup candy corn.
