9 to 10 tablespoons (135 to 150 grams) heavy whipping cream
½ teaspoon (2 grams) vanilla extract
Instructions
Refrigerate Browned Butter for 15 minutes, stirring halfway through. (It will be thickened but not set.)
In the bowl of a stand mixer fitted with the paddle attachment, beat Browned Butter, softened butter, and salt at medium-low speed until smooth. With mixer on low speed, gradually add confectioners’ sugar, about 1 cup (120 grams) at a time, alternately with cream, about 1 tablespoon (15 grams) at a time, beating until smooth after each addition. Add vanilla extract. Increase mixer speed to medium, and beat until fluffy, about 2 minutes.
