What You'll Need

  • 250g plain flour
  • 150g caster sugar
  • 1/2tsp vanilla extract
  • 1/4tsp salt
  • 1tsp emulsifier (I use Indonesian brand called 'SP' or 'TBM')
  • 2 eggs, whisked
  • 200ml Sprite
  • food colouring of your choice
  • steamed cupcake cups (with holes)

How to Make It

Step 1

Preheat your steamer, ensure the water is boiling rapidly. This is very important as the heat will be one of the factors that make the steamed cupcakes bloom. 

Step 2

Combine all the dry ingredients in a bowl. Make a hole in the middle then pour in the wet ingredients (including the emulsifier). Mix everything with a mixer in a high speed until all is mixed together well and the mixture is puffed up.  

Step 3

Take some of the mixture onto a small bowl and put some drops of food colouring of your choice.  

Step 4

Line the steamed cupcake cups with cupcake cases. Fill the cups into 2/3 full, then dollop some of the coloured mixture on top until it's 7/8 full. 

Step 5

Open the lid of your steamer, wipe the steamer with hand towel to ensure that the area where you are going to put the cups are dry. Put the cups inside your steamer. Make sure that you dont overcrowd the steamer. I usually use 2 steamer pan. 1 very big one, which I only fill with 5 cups, then another one smaller steamer which I fill with only 3 cups. This is to allow the top of the cupcakes to bloom nicely.  

Step 6

Line your steamer lid with hand towel to prevent moisture to drop on your cupcakes. Steam for 10-15 minutes.
