Brown crème de cacao is a sweet, deep-brown chocolate liqueur flavoured primarily with cocoa beans, the darker of the liqueur's two standard colour versions.
Rich cocoa and dark chocolate lead, backed by pronounced sweetness and a rounded vanilla note.
Serving as a low-strength chocolate flavour and sweetness modifier, it is shaken or stirred in small measures to bring cocoa character, sugar and a brown tint to a drink; where the chocolate is the point, it is not readily replaced.
White crème de cacao is the closest swap — the same cocoa-and-vanilla base with comparable sweetness, strength and body — but it lacks the deep brown colour and some of the dark version's chocolate intensity, so a drink meant to look chocolate-brown will come out pale; any substitute must still carry both a genuine cocoa aroma and substantial sweetness, which added sugar can top up but cannot manufacture the chocolate note from a non-cocoa source.
Both share the cocoa flavour base; the white version is clear, distillate-based and more delicate in chocolate flavour, while the brown/dark keeps a deep brown colour and a typically richer, stronger chocolate character.
Crème de cacao contains no dairy, whereas a chocolate cream liqueur is dairy-based; the 'crème' in crème de cacao refers to its high sugar content, not to any cream.
Brown crème de cacao takes its flavour from cocoa beans or nibs, distilled into a chocolate-scented spirit and/or macerated and infused in spirit, with sugar added and vanilla commonly folded in for aroma and sweetness. Despite the name, it contains no dairy — "crème" denotes a high-sugar liqueur, not cream. It differs from the white version chiefly in its deep brown colour and its richer, stronger chocolate character.
