St. Patrick's Day Rainbow Cupcakes: A Sweet Treat for the Holiday

St. Patrick's Day is a celebration of Irish culture and heritage, and what better way to celebrate than with some festive cupcakes? These rainbow cupcakes are not only delicious, but they're also a fun and creative way to show your Irish spirit.

Ingredients:

* 1 box white cake mix
* 1 cup water
* 1/3 cup vegetable oil
* 3 eggs
* 1 teaspoon vanilla extract
* Food coloring (red, orange, yellow, green, blue, indigo, and violet)

Instructions:

1. Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius). Line a muffin tin with cupcake liners.
2. In a large bowl, whisk together the cake mix, water, vegetable oil, eggs, and vanilla extract.
3. Divide the batter evenly among seven small bowls. Add red food coloring to one bowl, orange to the next, yellow to the third, green to the fourth, blue to the fifth, indigo to the sixth, and violet to the seventh.
4. Spoon a spoonful of each color of batter into each cupcake liner, alternating colors.
5. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
6. Let the cupcakes cool completely before frosting.

Frosting:

* 1 cup unsalted butter, softened
* 3 cups powdered sugar
* 1/4 cup milk
* 1 teaspoon vanilla extract
* Green food coloring

Instructions:

1. In a large bowl, beat the butter until light and fluffy.
2. Gradually add the powdered sugar, alternating with the milk, until the frosting is smooth and creamy.
3. Stir in the vanilla extract and green food coloring.
4. Frost the cooled cupcakes and sprinkle with rainbow sprinkles.

Tips:

* For a more intense rainbow effect, use a different shade of food coloring for each layer of batter.
* If you don't have a piping bag, you can spoon the frosting into a ziploc bag and cut off a corner to pipe it onto the cupcakes.
* These cupcakes can be stored in an airtight container at room temperature for up to 3 days.

Enjoy your delicious and festive St. Patrick's Day rainbow cupcakes!
