Print Recipe



  • cups unsalted butter 339 grams, room temperature (3 sticks)
  • 6 cups powdered sugar 678 grams
  • 1 lime juiced and zested (about 2 tablespoons juice and 2 teaspoons zest)
  • teaspoon kosher salt


  • In the bowl of a stand mixer fitted with the whisk attachment, combine all of the ingredients. Whip on low until the powdered sugar is about halfway incorporated, about 1 minute. If you whip at a higher speed before the powdered sugar is a little incorporated, it will fly out of the bowl.
    1½ cups unsalted butter, 6 cups powdered sugar, 1 lime, ⅛ teaspoon kosher salt
  • Increase the mixer speed to medium high and whip for another 30 seconds before increasing it to high. Whip for 3-4 minutes to allow the powdered sugar to dissolve into the butter and for it to get fluffy.
  • Frost your cupcakes or cake and enjoy! (We love to use this frosting on these fun Pinata Cupcakes)


  • Start your stand mixer on low before increasing it to a high speed. If you start it high, you will get clouds of powdered sugar all over your kitchen.
  • Use fresh lime juice rather than bottled for the zingiest flavor. For a milder lime flavor, you can leave out the zest.
  • This recipe makes enough for 2 cups of frosting.
Storage: Store lime buttercream in an airtight container in the refrigerator for up to 1 week or in the freezer for up to 6 months.
