I find the cake is soft, spongy and moist compared to baked version. Thanks Malati for sharing and hope there will be others who come forward to contribute their recipe too.
Here is the recipe translated into English:
2 cups Plain Flour
2 cups Sugar
2 cups Water
390g Condensed Milk
3 tbs Butter
1 tbsp Bicarbonate Soda
1 tsp Rose Essence
1. Stir sugar in a saucepan over low heat until melted & golden.
Pour in water & stir until sugar is dissolved. (Becareful of hot steam when pouring the water into hot caramel).
Boil & add in Butter & switch off fire.
2. Beat egg slightly & mix in condensed milk.
Add in flour gradually and lastly bic soda.
Add in golden syrup & rose essence.
3. Pour into lined & greased 8 inch round tin and steam for 1 1/2 - 2 hours.
