when you are a baker, you can do anything you want.. after all, only you will know what happen in the kitchen
当你懂得烘焙时,只要是自己要滴,都可满足。。毕竟,厨房里发生啥事儿,只有 you 和 you 知道


200g cold egg white (c. 5 large egg white)
50g sugar (A)
8g cornstarch

50g soy milk (sweetened or unsweetened is fine)
20g coconut oil
30g sugar (B)
58g cake flour
2-3 drops vanilla extract

245g sweet potato (net weight after steaming & de-skinning)
4 – 4.5 tbsp sweetened soy milk
* feel free to add some sugar if you like sweet filling. but the natural sweetness from sweet potato and soy milk is enough for us


冷蛋白 200克 (约 5大颗蛋白)
糖 50克 (A)
粟粉 8克

豆浆 50克 (甜或无糖豆浆允可)
椰子油 20克
糖 30克 (B)
蛋糕粉 58克
香草精 2-3滴

紫薯 245克(蒸熟并去皮后的净重)
甜豆浆 4 – 4.5大匙


IMG_8953– Mix coconut oil and sugar (B) together, then stir in soy milk. sift in flour and fold well
椰子油和糖 (B) 拌匀,加入豆浆。筛入面粉、翻拌均匀

– line a 25 x 25cm baking sheet with baking paper
25 x 25厘米烤盘铺上烘焙纸

– beat egg white with cornstarch till frothy. then add in sugar (A) in 2 additions and beat till stiff peak. change to low speed and beat for 1-2 mins to stabilise meringue texture
蛋白加入粟粉,打至出泡。糖 (A) 分两次加入,打至硬性状态。电动打蛋器转至低速继续打1-2分钟以去气泡,稳定蛋白霜

– add 1/3 meringue into the above and mix lightly. then add in another 1/3 of meringue and fold well

– pour the above into the remaining meringue and stir well. add a few drops of vanilla extract and stir quickly

– pour batter onto pan, even out well and bake for 18 mins in preheated oven of 160 degrees C
将面糊倒入烤盘,刮平,送入预热至160摄氏度烤箱烤 18分钟即可

– remove from oven, and cool cake with the bottom of cake facing up (i.e. the pale side)

– cut sweet potato into small pieces, and add 4 – 4.5tbsp of soy milk in food processor. blend well. the consistency of the puree should be like nutella
紫薯切小块儿后和豆浆放入食物搅拌器搅拌均匀。拌匀后的紫薯泥应该和 Nutella 巧克力榛果酱一样浓度

– spread sweet potato puree on cake and roll up tightly. chill for a few hours before slicing and serving

    Hi Victoria
    I am new to roll cake. Do I unmould the cake when it\’s still hot and peel of the baking paper? Also can you advise the depth of your baking tray that you use to make the roll.

    • Victoria Bakes (November 14, 2015)

      Hi Elaine, YES you MUSt unmould cake immediately and peel off the baking paper. place it back onto cake to prevent it from drying out. my trays are generally 1cm in depth

  • Elaine (November 14, 2015)

    Thanks for your prompt reply Victoria

  • Jaslin (December 2, 2015)

    All your swiss roll look so beautiful. If I just want to buy one baking tray for making swiss roll, what size do you recommend? Thank you in advance.

    • Victoria Bakes (December 2, 2015)

      I recommend a 25 x 25 or 28 x 28. But you have to know that these sizes when rolling cake, you will end up with either an \”O\” or big \”e\” shape and not a spiral effect. So you may prefer a more rectangular pan depending on personal preference but I like square pans in general.

    Do I cook the potato at all before I put in the food processor?

    • Victoria (August 3, 2019)

      Hi as mentioned in instructions, it needs to be steamed and deskinned
