Dewar's Whiskey Coffee Caramel Cake with Caramelized Hazelnuts is a decadent dessert that combines rich flavors of whiskey, coffee, caramel, and toasted hazelnuts. The cake is typically made with layers of moist, fluffy sponge cake that are infused with a mixture of Dewar's whiskey and coffee. The cake layers are then filled and covered with a smooth and creamy caramel frosting, made from butter, sugar, cream, and caramel sauce.
