No, this cake is not made with any artificial colouring. The greeness came from pandan juice. I made this cake based on Aunty Yochana's recipe. I didn't put in kaya, so I didn't name this cake as she did.
This cake is nice to eat, best with a cup of tea... teh-o to be exact :)
Pandan Butter Cake
250 gm. butter
200 gm. sugar
6 nos. eggs
300 gm. cake flour
1 tsp. baking powder
180 gm. coconut milk
50ml pandan juice
1/4 tsp. salt
(1) Sift flour and baking powder. Set aside.
(2) Cream butter and sugar till creamy.
(3) Add in egg one at a time and make sure it's properly mixed before adding in another egg. Pour in coconut milk, pandan juice and salt and mix.
(4) Fold in sifted cake flour and then pour into a 7" sq. tray and bake at 175C(preheated) for about 60 mins.
I will post on how to make really concentrated pandan juice, and more pandan flavoured recipes coming up.
*update: 2/6/2016: Please take note that this cake is rather tricky. It's better to overbake it. Back in those days, I baked this cake in a Microwave convection oven and I actually recommend baking this cake at 180C for 1 hour 15 minutes in a regular oven. And always check the doneness with a toothpick right in the center, all the way down before stopping the baking process. An 8 inch cake pan will be a better choice. Aunty Yochana noted it as 7 inch, so I just followed suit, but personally I think an 8 inch square pan or 9 inch round is better.
** update 22/5/2017:
Please visit Aunty Yochana's website if you doubt this recipe to see the success of other bakers rather than complaining about this recipe.
If you will prefer a more foolproof recipe, my personal suggestions is that you use 100ml concentrated pandan juice and 25gm of coconut milk powder rather than coconut milk. Change the cake flour to plain flour + another tsp of baking powder. Use an 8 inch square or a 9 inch round pan.
This cake was baked back in 2009, when I started blogging not long. I just copied her recipe almost word for word. It worked well for me, and for some others, like I said in above that I needed to bake it much longer than what Aunty Yochana said. I didn't create this recipe, but if it didn't work well for you, I'll try to help you troubleshoot.
If many others can get it right, and you can't, think about it.
