  • 1 cup butter unsalted and softened
  • 3 cups powdered sugar depending on the humidity/heat that day sometimes I have to add about 1/2 - 1 cup more, play around with it until you reach the consistency you desire
  • 1/4 cup whipping cream
  • 1 tsp vanilla extract
  • 1 pink food coloring
  • 1 blue food coloring
  • 1 yellow food coloring


  • In your mixer add the butter and slowly begin to beat it on a medium setting. Once it's soft, add the sugar.
  • On a slow speed mix until incorporated (and to prevent sugar going everywhere) and then beat until fluffy. This takes a few minutes.
  • Scrape the bowl, add the cream and vanilla.
  • Turn the beater to high and let it whip up for about five minutes. You may need to pause and scrape the bowl a few times.
  • Divide the frosting into four bowls: leave one the original color and then color the three with the colors your chose.
  • Spoon the colors into a piping bag, focusing on the sides more so the colors come out at once and pipe!
