Lemon Buttercream

Level: Easy
Yield: Enough to cover a two-tier 8" cake, or 2 dozen standard cupcakes


  • Zest of 2 large lemons (about 1 heaping tablespoon)
  • 3 tablespoons lemon juice
  • ½ cup (1 stick) unsalted butter, at room temperature
  • ½ cup (1 stick) salted butter, at room temperature
  • 4½-5 cups sifted powdered sugar
  • 1 tablespoon heavy cream


1. Zest and Juice

Zest two large lemons using a microplane zester. (It should equal about a tablespoon or a bit more.) Make sure to only zest the yellow parts of the skin and not into the pith (the white spongy part underneath the yellow).

Juice one of the lemons. Measure out 3 tablespoons of lemon juice and set aside.

2. Cream

Add both butters and lemon zest to a stand mixer bowl and cream using the paddle attachment at medium speed. Beat until smooth and fluffy, for about 2 minutes, scraping sides as needed. Alternatively, you can use a hand mixer.

3. Sift and Beat

Sift the powdered sugar and add 2 cups into the bowl. Beat at low speed to prevent the sugar from being pushed out of the mixer. Then increase the speed to medium.

4. Add the Juice

Add the lemon juice and remaining 2½ cups of sugar. Beat for another 2 minutes. Add a tablespoon of heavy cream or use the extra ½ cup of sugar to get the consistency to your liking. Use immediately.
