- Prepare the cake batter as directed on the box. Once the batter is mixed, separate the batter into two separate bowls trying to get equal amounts of the batter into each bowl.
- In one bowl add the red food coloring and in the second bowl add the blue. Each brand of food coloring seems to vary as far as coloring so use the amount of food coloring you feel necessary to achieve the desired shades of red and blue.
- Once both batters are colored, line the mini cupcake pan with the mini cupcake liners and fill with the two cake batters (make solid color cakes, do not mix the colors) and bake as directed on the package. (Try to bake equal parts of both red and blue mini cupcakes.)
- Once the cupcakes are done baking set on the counter and allow to cool completely.
- Once cool remove the cupcakes from the pan and remove the cup cake liner. Slice each cupcake in half (so you have a top and a bottom). Do this for the all of the remaining cupcake
- On a large serving plate place the bottom of one of the red cupcakes. Add frosting then adding the top of the cupcake. Repeat with the remaining cupcakes.
- Garnish with extra frosting and red white and blue sprinkles and serve.
