Pio Quinto: Nicaraguan Rum Cake

Description
Pio Quinto is a Nicaraguan rum cake topped with a vanilla custard (natilla) and dusted with cinnamon. This cake may have been named after Pope Pius V and there is also a Pio Quinto River in Nicaragua but the exact origin for the name of this dessert is not known.

This is a delicious and light version of Pio Quinto, made with a butter substitute in the rum glaze and egg whites in the cake. The recipe yields 6 mini cakes. Instead of traditional Natilla that uses milk and egg yolks, this custard is made with light coconut milk. Like Natilla, it is thickened with cornstarch. The resulting custard is airy and light and deliciously creamy. It is just incredible paired with the rum cakes! Rum-soaked dried plums are also a nice addition and make the cakes look very pretty.
