Using a standing mixer, combine all ingredients and mix on medium speed.
If your frosting starts looking like powdery rocks, add another tablespoon of heavy whipping cream.
Mix until you see creamy stiffed peaks.
Once the frosting is made, split it into two bowls.
Add about 2 drops of each color in their own bowls and mix until the color is completely mixed.
Scoop the pink frosting into the first disposable piping bag.
Scoop the blue frosting into the second disposable piping bag with the star tip.
