抹茶魔术卡士达蛋糕 Matcha Magic Custard Cake (中英食谱)


Few weeks ago, when my good friend Joyce posted her bake of this magic custard cake in her facebook, I was curious and wonder why it is called a magic cake. She explained to me that three different layers were formed when the cake is baked. I thought, "Wow, what an interesting recipe, I gotta try it!"
I got the recipe from her and baked it yesterday specially for my daughter who has completed her school preliminary examinations. I added Matcha powder to the recipe to make a Matcha flavoured one as I am in the series of making matcha bakes. You can take a look at my earlier posts if you are a Matcha fan like me.
When I was making this cake, it was so watery (my friend has forgotten to warn me about this) that I wondered if I have read the ingredients and measurements correctly. Anyway, I moved on to make the meringue and folded it into the watery batter. Things got worst, the batter became very curdy and I thought I have ruined it and was on the verge of discarding it when I changed my mind. (thinking it was such a waste to pour away!) I tried my best to fold the whites in with a hand whisk (switching from a silicon spatula) until there were no big curds around. Frankly speaking, I was not hopeful that the cake will turn out alright. I just wanted to see the outcome thus went ahead and put it into the oven to bake.
To my surprise, not only did the cake turned out fine, it was truly magical! There were three layers of different texture, the top layer is like a soufflé cake (it will rise when baked and sank when taken out of the oven), the centre is a soft custard layer and the bottom is a denser 'kueh' (a type of chinese/malay cake) texture. When the cake was cooled down, I couldn't wait to help myself to a piece, it was so delicious that I took another helping. Not only does it taste good, the sweetness is just right too!
From what I know, the recipe is originated from Spain. Hope you will like this cake as much as I do and it tastes good either warm or cold. 

首先要在这感谢我的好姐妹Joyce与我分享这英文的食谱。几个礼拜前,看到她在Facebook上载原味的魔术卡士达蛋糕 , 真的很好奇怎么会有这样有趣的食谱,仅然能烘培出三层不同质感的蛋糕呢?我想多数人也跟我一样,从没听过,也没吃过。对这个神奇的甜点超感兴趣,也想尝试制做它吧!

不瞒你说,在制做这蛋糕时,因为面糊是水水的 (朋友忘了提醒我这点),我还以为我看错了材料的份量,差一点就把面糊拿去喂 Mr Bin了!。不过想继续做下去,看加入打发到硬性的蛋白霜,会不会好一点。 没想到,面糊加入了蛋白霜后有好多大大的凝块!我心想:这下子更糟了,怎么办?是不是真的该把它给倒掉了?想想后又觉放进预热好的烘炉。 当时并不是很乐观蛋糕会成功。  过了大概得很浪费, 就拿起了手拌器,尽量把大块的固体搅拌散, 再一小时,把烤好的蛋糕拿出一看, 真的有三层!太高兴了,糊里糊涂的成功了,哈哈!蛋糕的上层象是Souffle的味道,中层是软软的卡士达,下层象Kueh的质感。口感很棒,你会不知不觉地吃下好几块呢!这么神奇又好吃的蛋糕一定要试做,并不难哦! 

据我所知,食谱的来源是西班牙。希望你会和我一样喜欢这个蛋糕。它的味道不管是刚烤出来或放进冰箱后,都一样好吃, 赞不觉口!我和家人都很喜欢,一定会再做。

Please watch the tutorial video before attempting this cake:

Matcha Magic Custard Cake (makes a 8" square pan)

113g unsalted butter (I used Echire Doux French butter)
485g fresh milk
1 tablespoon water
4 eggs, separated (60g each, weight including shell) 
100g plain flour
15g premium Matcha powder (replaced with plain flour for original flavour, replace with unsweetened cocoa powder for chocolate flavour)
145g icing sugar
2 Tbsp caster sugar
1 tsp vanilla extract
Extra icing sugar for dusting (I use snow powder, which will not melt when put into the fridge)

113克 无盐牛油 (我用上等的Echire法国牛油,味道更佳)
485克 鲜牛奶
鸡蛋4粒,分隔  (每粒60克包括壳)
100克 普通面粉/中筋面粉
15克 上等抹茶(可以由普通面粉取代做原味的或用无糖可可粉取代做巧克力口味的)
145克 糖粉
额外的糖粉,洒在蛋糕上层。我用放进冰箱不会融化的 Snow powder)

1. Preheat the oven to 160ºC. Lightly grease and line a 8"x8" baking pan with baking paper.
2. Melt the butter and set aside to cool slightly. Warm the milk to lukewarm and set aside.
3. In a separate bowl, sift flour and matcha powder together.
4. Use an electric mixer and whisk the egg whites till foamy, add in the caster sugar and whisk till stiff peak. (make sure there is no oil or water in the bowl, the egg white must not come into contact with any egg yolk, water or oil too or the meringue will not be succesful.)
5. In another bowl. beat the egg yolks and icing sugar until light and fluffy.
6. Add in the melted butter and one tablespoon of water and beat for about 2 minutes or until evenly incorporated.
7. Mix in the sifted flour until evenly incorporated.
8. Use a hand whisk and gently beat in the milk and vanilla extract until everything is well mixed.
9. Fold in the egg whites, 1/3 at a time. Repeat until all of the egg whites are folded in. (The batter will appear curdy, just fold till no big curds are seen)
10. Pour the batter into the prepared pan and bake for 50-55 minutes until the top is golden, test with a skewer which comes out clean, the cake is done.
11. Allow cake to completely cool before cutting and then dust with icing sugar.

*** It's a magical cake that forms into 3 layers when baked. The bottom layer is dense and taste like our chinese kueh, the centre layer is soft and custard-like and the top layer is a souffle cake texture. (which is normal for the cake to shrink after cooling down) 
Note: It is normal that the batter is runny and after adding in the meringue, it will become curdy. Don't panic, just continue to fold until the curds almost disappear.

Frequently Asked Questions:
Qn 1) Why does my cake only have two layers instead of three?
Ans: Please ensure that the egg yolk is beaten till light and fluffy and the egg white is beaten till stiff peak. It is also important to fold in the beaten egg white into the flour-milk mixture using a rubber spatula and not using the electric mixer in this step as it will cause the air bubbles to disappear. Actually, it doesn't matter if the cake only has two layers as it is still a very delicious cake.

Qn 2) Why doesn't my cake rise and even shrank after cooling down? 
Ans: This cake does not rise much, the height of the cake is the height of the cake batter when you poured into the baking pan. Please look at the before and after bake photos in step 9. It is normal for the cake to shrink after cooling down as the top layer is a souffle texture. 

Qn 3) Can I use a round baking pan with removable base instead of a square one? 
Ans: Yes, you can. You have to lay the baking paper all over the pan properly and put a layer of aluminium foil to wrap the exterior of the base pan so that the batter will not leak out. 

Qn 4) Can I use a square pan without a removable base? 
Ans: Yes you can. Make sure the height of the baking paper laid is taller than the pan so that you can lift the cake out easily to cool on a wiring rack. 

Qn 5) Why does my cake collapse when I cut it?
Ans: This cake is soft and wobbly when out of the oven. Please cut it only when the cake has cooled down completely. 

Qn 6) Why does my cake surface crack during baking?
Ans: You have to bake at a lower temperature and longer time as the suggested temperature is too high for your oven. 

Qn 7) Why are some layers thicker or thinner than the others?
Ans: This is a one batter recipe, we can't control the thickness of each layer in the cake. It will have to depend on the magic that takes place during baking. 









8。用手拌器轻轻地打入牛奶和香草精,直到混合。(如果继续用电动搅拌器, 水水的面糊会被打到四处飞哦!)


10。将面糊倒入烤盘,烤约55分钟,直到表面呈金黄色, 竹签插入中心没有沾粘就可以取出。
