Instructions

1. Preheat the oven to 350 degrees F. Line a 12-cup muffin pan with 12 cupcake liners. Set aside.
2. Start by making the cupcakes. Whisk together the flour, baking powder, and salt in a mixing bowl. Set aside.
3. In a large mixing bowl, stir the oil and sugar together with a whisk until light and fluffy. Add the eggs and vanilla extract to the sugar and oil and mix until just combined.
4. Stir in the milk then fold in the dry ingredients until just combined.
5. Divide the batter into 2 bowls, then add the yellow food coloring into 1 bowl and the orange food coloring into the other. Stir with a spatula until the colors are evenly mixed.
6. Spoon 2 tablespoons of the yellow batter into the bottom of the cupcake liners, then spoon 2 tablespoons of orange batter on top of that. Cupcake liners should be about ⅔ full.
7. Bake in the preheated oven for 15 minutes or until a toothpick inserted into the middle cupcakes comes out clean. Allow the cupcakes to cool to room temperature.
8. While the cupcakes cool, make the frosting. Cream the butter with an electric mixer. Mix in the marshmallow fluff until smooth. Gradually add in the powdered sugar until the frosting is thick and smooth.
9. Transfer the frosting to a piping bag with a large tip, and pipe the frosting on the cooled cupcakes. Decorate with candy corn and sprinkles, if desired, and serve.
