Chiffon cakes tend to feature delicate aromas such as lemon. This cake takes a different route to flavor with rich-tasting cocoa powder, cinnamon, and brewed espresso. Walnut oil gives the cake a delightfully nutty quality, but you could also use extra-light olive oil.
雪紡蛋糕一般都會(huì)帶有檸檬的芬芳，不過這一款西雅圖雪紡蛋糕走了一個(gè)不同的路數(shù)：加入厚重的可可粉、肉桂和現(xiàn)泡意式濃縮咖啡，而核桃油的使用也給它帶入一種令人愉悅的堅(jiān)果口味。不過你也可以用超低脂的橄欖油替代。
