Fluffy Steamed Cupcakes

I went through few times failure, before finally manage to make the one above. 
Baking teaches me to not being afraid to fail. And maybe it's never a failure, 
it's merely a success finding out what does not work :p.

Serving :  10  cup

INGREDIENTS 

2 organic eggs 

180 g / 1 cup granulated sugar 
250 g / 2¼ cup flour 
150 cc soda drinks    
½ tsp emulsifier
½ tsp double acting baking powder 

¼ tsp salt
¼ tsp vanilla essence
¼ tsp choco pasta (for coloring)

               

DIRECTION 

1. Cream eggs, sugar, emulsifier until the batter is thickened (25 mins)
2. Pour the flour and soda in turn little by little, keep mixing for another 10 minutes
3. While waiting, cover the steamer's lid with clean cloth, heat the steamer
4. Divide the batter into 2, color one of the batter with choco pasta
5. Pour 3/4 vanilla batter, followed by 1 tbsp choco batter, 1 tbsp vanilla batter, in turn till full
6. Steam for 15 minutes in big fire. Do not open the lid before the cake is done
7. Give extra space between as these cakes need a lot of steams to perfectly rise and crack in the middle
