Coffee Agar Agar Zebra Chiffon 咖啡布丁戚风蛋糕

I couldn't make up my mind. I wanted to try baking a custard layered cake but I do not have all the essential ingredients. I wanted to try baking a zebra chiffon but I'd never done it before.....So in the end...I married them all and did a Coffee Agar Agar Zebra Chiffon 咖啡布丁戚风蛋糕. It's my own creation. I used both instant coffee and coffee liquor to get a nice coffee aroma. Loving it! 

Group A - Cake Ingredients (For Yolk Batter) :
  • 120 gm TOP or cake flour

  • 5 egg whites (est. 65 gm eggs)

  8. Combine meringue onto egg yolks mixture in 3 batches. Gently fold till even.
  9. Divide combined cake mixtures into 2 equal bowls. 
  10. Mix cocoa powder (from Group B) into only one bowl and gently fold to create a darker cake mixture.
  11. Line baking paper at bottom of a 7-inch round cake tin.
  12. Gently fold in alternate colours into cake tin layer by layer. Scoop equal amount of each colour every time. 
  13. Gently tap cake tin few times to remove any air bubbles after each layer.
