Switch to the paddle attachment. With mixer on medium-low speed, add butter, several tablespoons at a time, beating well after each addition. (If frosting appears to separate after all the butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.) Beat in vanilla. Beat on lowest speed to eliminate any air bubbles, about 2 minutes. Using a rubber spatula, gently fold in passion fruit curd until smooth.
