After seeing some successful attempt at this cake by my internet buddies, I was tempted to try myself. I used Jo's Pandan chiffon cake, and the kaya recipe contributed by Nora.
As requested, here it the recipe of the pandan custard by Nora, and also her excellent tips!
Kaya Topping
Ingredients:
500ml water
160-200g sugar
50g butter (to make the texture smoother)
150ml water
250g coconut milk
80g hoon kueh powder
½ tablespoon instant jelly
Green and yellow colouring
Method:
1. Boil water (500ml), sugar and butter until boiled.
2. Mix coconut milk with water (150ml), hoon kueh powder, instant jelly and colouring together and add into 1 and cook until thick.
3. Must be boiled. (If you find that it is not thick enough, you can use a bit more hoon kueh to mix with some water and add in.)
To Assemble
1. Surround the cake with a 9” cake ring and put layer of cake in then followed by kaya, then cake alternately depending on how many layer you want, but the top layer must be the kaya.
2. If you are using cake tin, then kaya first and then cake then kaya and last layer is cake.
3. Let the cake cool down then put it in the fridge to set for few hours or overnight.
4. Then after you may coat the side with desiccated coconut.
NOTES BY VARIOUS PEOPLE
1. You can use your own sponge cake recipe, just add pandan essence to make it green if you find troublesome to buy optima flour and ovalette.
2. If it is too difficult to buy optima flour and ovalette, you can actually use the premix for sponge cake, my friend tried and said result is about the same. Just make sure you add pandan paste into your cake mixture instead of pandan essence which I find is better.
3. I think the key point for this cake is the kaya spread.
4. My teacher used a knife to go round the tin to loosen the cake. He said if you don’t have instant jelly; don’t put agar-agar powder as it will harden the kaya. Just need longer time to set in the fridge. Don’t use gelatine too, as gelatine is for making mousse cake. If you don’t have hoon kueh powder, you can substitute with corn flour but hoon kueh smell nicer. (I only can smell coconut but not the hoon kueh.)
5. Actually I did it with agar-agar powder, and the result is just as good. I used ½ tablespoon agar-agar powder.
6. One thing to note is that try making more kaya, because the last time I bake this, I found it isn’t enough to cover the side of the cake.
7. I use a layered cake cutter to cut the cake evenly.
8. Your cake has to be completely cooled, then you boil the kaya. You need to assemble the kaya and cake when the kaya is hot.
9. To get a smooth surface:
a) Use a cake tin, wash it but don’t dry it, it should be wet with water droplets.
b) Pour some kaya into the cake tin, spread it evenly.
c) Then put in a layer of sponge cake, press down the cake a little in order for the cake to stick to the kaya.
d) Then pour some kaya on top of the sponge cake, and spread it evenly.
e) Same as step C.
f) Same as step D.
g) Put the last layer of cake.
h) It is up to individual how many layer you want to make your cake.
i) Then chill the cake.
