Considering the passionfruit originated in Brazil, it is little wonder that it features in so many of the nation’s desserts. This simple sponge cake is not only laced with passionfruit, it is then drizzled in a rich passionfruit syrup for a double dose of tangy sweetness. Some versions of this cake also include a passionfruit mousse sandwiched between layers of the sponge. It is best served the day it is made.
