The main difference between this Biscoff Tiramisu recipe and a traditional tiramisu recipe lies in the key ingredient used for the biscuit layer. Traditional ladyfingers, known as savoiardi, are used in the conventional version.  However, in this Biscoff Tiramisu recipe, Lotus Biscoff biscuits are substituted, adding a unique and distinct flavor to the dessert. Additionally, the traditional tiramisu recipe typically uses strong brewed coffee or espresso as the soaking liquid for the ladyfingers.  In this Biscoff Tiramisu variation, the recipe suggests using a mixture of espresso and water, with the optional addition of coffee liqueur or dark rum, to dip the Biscoff biscuits. This infusion of flavors gives the dessert an Amazing twist. Apart from these differences, both recipes share similar components, such as the creamy mascarpone filling, the use of egg yolks and sugar for a rich custard-like layer, and the addition of cocoa powder for dusting. Overall, the Biscoff Tiramisu recipe introduces the beloved flavors of Biscoff biscuits into the traditional tiramisu, resulting in a fusion dessert that offers a delightful blend of cinnamon, caramel, and spices alongside the classic creamy and indulgent elements of the original dish.
