⅔ cup (150 grams) unsalted butter, room temperature
¾ teaspoon (1 gram) packed lemon zest
⅛ teaspoon kosher salt
2⅓ cups (280 grams) confectioners’ sugar
2½ tablespoons (37.5 grams) heavy whipping cream
Instructions
Assemble Ankarsrum mixer with plastic bowl and balloon whisks. Add butter, lemon zest, and salt. Beat at high speed (6 o’clock) until combined, about 1 minute, stopping halfway to scrape sides of bowl. Add confectioners’ sugar and cream; begin mixing on lowest speed (12 o’clock), gradually increasing mixer speed to medium-high (5 o’clock), and beat until fluffy, about 2 minutes. Use immediately.
