If an Aperol spritz — the Venetian cocktail made from Aperol, prosecco and soda water — is the drink of summer, then this Aperol Spritz Bundt Cake is definitely the cake of summer.

It wasn't until 1919, though, that Aperol made its debut in Padua. The recipe for the orange-coloured aperitif took the Barbieri brothers seven years to perfect – and remains intact to this day.
