Passionfruit Frosting Recipes

Steps:

• Cake: Preheat oven to 350°F. Brush a 9-by-13-inch or 8-by-12-inch baking pan with butter. Line with parchment, leaving a 2-inch overhang on long sides. Butter parchment.
• Whisk together flour, baking powder, baking soda, and salt. Combine eggs and granulated sugar in the bowl of a mixer fitted with the whisk attachment. Beat on high speed until thick and pale, about 4 minutes. Add flour mixture; beat just to combine. Add butter, bananas, cinnamon, and vanilla; beat to combine. Add sour cream; beat until smooth.
• Scrape batter into prepared pan, smoothing top with a spatula. Bake until top springs back when lightly touched and a tester inserted in center comes out clean, 30 to 35 minutes (for 9-by-13-inch) or about 40 minutes (for 8-by-12).
• Let cool in pan on a wire rack 10 minutes. Using parchment overhangs, lift cake out of pan and let cool completely on rack. (Cake can be made to this point and stored at room temperature, wrapped in plastic, up to 1 day.)
• Frosting: Beat together cream cheese, butter, confectioners' sugar, and passion-fruit juice on medium-high speed until smooth and fluffy, about 5 minutes. Spread over top of cake; drizzle with passion-fruit pulp. Frosted cake is best the day it's assembled, but can be refrigerated, wrapped in plastic, up to 1 day. Return to room temperature before serving.

Steps:

• In the heatproof bowl of an electric mixer set over (but not touching) simmering water, combine egg whites and sugar. Cook, whisking constantly, until sugar has dissolved and mixture is warm to the touch (about 160 degrees).

• 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.

Steps:

• Beat the butter and cream cheese with mixer or whisk (good arm exercise) until light and fluffy.
• Gradually stir in the passionfruit pulp and powdered sugar.
• Adjust with more passionfruit pulp or powdered sugar to achieve the consistency you want.
