Directions/做法

stir vanilla paste into eggs and allow to steep
香草膏倒入蛋液。拌匀、静置待用 beat butter and sugar till cream then add in egg in 3 additions
黄油和糖打发至蓬松状后，蛋液分三次拌入 add in flour in 3 additions and milk + yogurt in 2 additions
i.e. add in flour, stir well, add in milk+yogurt and blend well
repeat process, and finish off with addition of flour
面粉分三次倒入、牛奶和酸奶分两次倒入
既是：倒入面粉、拌匀后，加入牛奶和酸奶～拌匀
步骤重复，以面粉收尾 add in almond meal and incorporate well
加入杏仁粉、拌匀 mix cocoa powder with water, then add in 17g of batter
dollop cocoa batter into original batter and swirl away (see my video below)
可可粉和水冲开
加入 17克面糊～拌匀
可可面糊用勺子随意点入原面糊然后开始画云石咯（见视频）

pour batter into greased & lined pan and smooth the top
面糊倒入抹了油并铺上油纸的烤盘。面糊铺平 bake in centre rack of 180 degrees C preheated oven for 70mins
allow cake to cool in pan for 15 mins before unmoulding
送入预热至 180摄氏度中层烤箱烤 70分钟
蛋糕出炉后等 15分钟才脱模哈 an absolutely optional step ~ if you want your cake to spilt nicely, slit it once the top has crusted
(about 25 mins into baking time for me)
此步骤可免～ 如想蛋糕顶部裂得有规则，可在蛋糕顶部结皮后划上一刀
（我的大约在入炉的 25分钟后就结了一层后皮）

Personal notes/温馨小贴士:

– you can also use an 8 inch square pan. reduce baking time to 50-60 mins
您也可选用 8寸方形烤盘。烘焙时间减至 50-60分钟

– don’t feel tempted to swirl the cocoa batter more than thrice as your entire cake will end up in a light chocolate colour after baking
可可糊切勿拌多过三次！过度翻拌会造成烤出来的蛋糕变（很浅）巧克力色！
