1. Prepare and make the box cake mix batter in a large bowl as directed on the box.
2. Divide the batter equally into three small bowls.
3. Add blue food coloring to one small bowl and red food coloring to another separate bowl. Stir until a rich, dark color is reached.
4. Preheat the oven to 350 degrees fahrenheit. Prepare a muffin tin with white cupcake liners.
5. Layer cupcake batter into the muffin cups. Drop 2 tablespoons of blue batter, 2 tablespoons of white batter and then 2 tablespoons of red batter into each cupcake liner.
6. Bake for 20 minutes or until a toothpick inserted into the center of a cupcake comes out clean. Place cupcakes on a wire rack to cool.
7. Use a piping bag with a 1M star tip to frost each cupcake with icing.
8. Top with festive red white and blue sprinkles.
Notes
Add enough food coloring to create a vibrant cake batter color as the color will fade in the baking.
