This luxurious twist on classic tiramisu pairs decadent chocolate with aromatic tonka beans for an exotic flavour profile. Coffee-soaked sponge fingers are enhanced with Urban Rhino liqueur, introducing complex vanilla and spice notes that perfectly complement the tonka bean's unique character. For additional depth, a splash of aged rum brings caramel undertones that elevate without overwhelming. The result is a sophisticated dessert that balances creamy mascarpone, rich chocolate, and subtle boozy notes—a refined interpretation that honours tradition while embracing bold innovation.
