Toffee liqueur is a sweet and buttery liqueur that captures the rich flavor of caramelized sugar and butter. It can be used as a base spirit or as a flavoring component in cocktails. Toffee liqueur pairs well with other sweet ingredients like chocolate, coffee, or cream. It can also be used to add a touch of sweetness and depth to whiskey or rum-based cocktails, such as a Toffee Old Fashioned or a Toffee Rum Sour.
