Roti Kukus (Indonesian Steamed Cake)

1st attempt - use reusable silicon bake cup

2nd attempt - use paper bake cup

Roti kukus is a traditional steamed cake originally comes from Indonesia.
Kids love roti kukus. I remember when I was a kid, my mom used to came home from 'arisan' (wiki: monthly social gathering between friends who chip in money to be won in turns through a lucky draw) and brought one box with 2 or 3 snacks in it. And I was so happy when one of them was roti kukus. It was always be the first to grab.


Yesterday, out of the blue, my husband said that it would be really great if he could eat roti kukus, remember the moist texture and the sweet flavour and the cute colors..  So I was thinking, hmm.. maybe I could find some good recipe from the internet. And I found one. 


This recipe is adapted from here with a little modification:


3 egg yolks
1 egg white
180 gr granulated sugar (3/4 cup = 170 gr, 1/4 cup = 55 gr)
180 gr plain (all-purpose) flour (180 gr = 1,44 cup)
100 ml sprite
1 tbsp cocoa powder


1. Prepare steamer for about 15 minutes. Make sure it is heated enough.
2. Line roti kukus moulds with parchment paper
Many people recommend to use special mould for roti kukus. But I used paper/silicon bake cup and it was doing fine. 
3. Beat egg yolks, egg white, and caster sugar until thick and pale.
4. Fold in 1/3 of the flour, then 1/2 of the sprite. Gently mix. Repeat with remaining flour and sprite, ending with flour. Mix thoroughly until there is, no lumps in the batter.
5. Divide 1/3 of the batter into a small bowl and add cocoa powder. Whisk until thoroughly combined.
6. Spoon white batter into moulds. Swirl a little of the chocolate batter. Steam for 15-20 minutes on high heat. 
I would really recommend putting small amount of batter in each mould/bake cup. Just to make sure that roti kukus will bloom and look a little cuter ;)
And you may put paper towel before closing the steamer, to avoid the water from dropping into the cake. 
Last but not least, do not open the steamer for the first 15 minutes.
7. Open the steamer and you'll be glad to see they're bloooomingggg..
