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.
雪纺蛋糕一般都会带有柠檬的芬芳,不过这一款西雅图雪纺蛋糕走了一个不同的路数:加入厚重的可可粉、肉桂和现泡意式浓缩咖啡,而核桃油的使用也给它带入一种令人愉悦的坚果口味。不过你也可以用超低脂的橄榄油替代。

How to make it
制作步骤

1. Preheat the oven to 325°F. Stir together the flour, sugar, baking powder, cinnamon, and salt in a medium bowl.
325华氏度(160摄氏度左右)预热烤箱。将面粉、糖、烘焙粉、肉桂和盐混合,倒入一个中等大小的碗里。

2. Whisk the walnut oil with the egg yolks, espresso or coffee, cocoa powder, and vanilla together in a large bowl until smooth. Fold the flour mixture into the egg mixture until well-combined.
充分搅拌核桃油、蛋黄、咖啡、可可粉和香草精,然后将第一步中的混合物倒入,充分搅匀。

3. Beat the 6 egg whites until frothy in a small bowl. Beat in the cream of tartar and continue beating until stiff peaks form. Gently fold egg whites into the batter.
将6个蛋清打至起泡,加入塔塔粉,继续打成最细小的泡沫状,翻碗不倒。再慢慢加入之前的混合物。

4. Spoon the batter into an ungreased 10-inch tube or Bundt pan. Bake until a toothpick inserted in the center comes out clean, about 45 minutes.
将混合物倒入不加油的浅烤盘,烤45分钟左右。直到你用牙签插入正中、抽出时干净无粘着,就可以享用啦!
