Prep Time 10 minutes
Total Time 10 minutes


  • 1 ¼ stick butter (about 10 tablespoons), soft
  • 1 cup powdered sugar
  • pinch salt
  • tsp cherry koolaid
  • tsp grape koolaid
  • tsp lemon koolaid
  • tsp strawberry koolaid


  • In a mixing bowl, add the room temperature soft butter and mix it on medium with the paddle attachment for 2-3 minutes.
  • With the mixer running on low, add the powdered sugar a little at a time by the spoon full. Combine completely before adding the next spoon full.
  • When all of the powdered sugar is added, turn the mixer to high and whip for 3 minutes, or until the buttercream is super light and fluffy.
  • Add the koolaid flavors to the buttercream and mix until combined completely.
  • Fill into a piping bag and pipe onto each macaron shell.

For the Macaron Shell

  • Follow the basic macaron shell recipe. Add a few drops of yellow food coloring when mixing for a pale yellow color, and sprinkle with a few white non perils once the shells are piped!
