This elegant dessert consists of a tender, black chocolate cake topped with a maple-tahini mousse and then enveloped in a glossy ganache. While it’s impressive enough for special occasions, this cake is surprisingly simple in its preparation. The complexity comes in the taste, with the subtle toastiness of sesame oil and the delicate fragrance of orange blossom water as background flavors that highlight the nutty tahini. The mousse topping is light and not too sweet, using mascarpone cheese instead of gelatin to stabilize the whipped cream and relying only on the natural sweetness of maple syrup. The warm depth of brown sugar and the distinct flavor of black cocoa, an ultra-alkalized version of Dutch-processed cocoa, gives the cake a nostalgic Oreo-cookie profile, and the salt accentuates the dark chocolate, bringing everything into balance.
