It’s an easy banana sheet cake that can be made in a 9-by-13-inch or 8-by-12-inch baking pan. The cake is moist and sweet thanks to a cup of mashed ripe banana in the batter and tender thanks to sour cream. It’s delicious on its own, but when you top it with our passion-fruit frosting, it’s sublime. The simple frosting starts with cream, confectioners’ sugar, and butter. Passion-fruit juice gives it a tropical flavor. Use the actual fruit rather than store-bought passion fruit juice if you can to have passion fruit pulp to decorate the cake. 21 Easy, Crowd-Pleasing Sheet Cakes for Any Occasion Making Banana Sheet Cake Ahead You can make and bake the cake up to one day before serving.
