Heavy Whipping Cream

Confectioner's Sugar

Food Coloring

Vanilla Extract

Air Heads - Rainbow Sour Strips

Step 2: Preparing the Cake Mix

Step 3: Separating the Cake Mix

Separate the cake mix into six different containers.

Step 4: Dying the Cake Mix

Add as much food coloring as your desired color.

Step 5: Prepare the Cupcake Pan

Place cupcake liners on the cupcake pan.

Step 6: Filling the Cupcake Liners

Place a teaspoon of each individual colored cake mix into each cupcake liner.

Step 7: Bake

Bake as directed on the cake mix box.

Step 8: Let the Cupcakes Cool Down

Remove the cupcake pan from the oven and allow cupcakes to cool down completely.

Step 9: Prepare the Frosting

Mix 1 cup of whipping cream, 1/4 cup of confectioner's sugar, and approximately one teaspoon of vanilla extract (flavor the frosting to your desired taste).

Step 10: Color the Frosting

Add blue food coloring to resemble a sky blue color. Using an electric mixer, mix at a medium high speed. Add additional food coloring if you wish your frosting to be a little darker.

Step 11: Piping the Frosting

Using a rubber spatula, place the the prepared frosting inside a ziploc bag. Seal the bag and cut a corner off with scissors. Start by piping frosting around the outside edge of the top of the cupcake and move the Ziploc bag in a spiral motion inward until ending in the very middle of the cupcake.
