Hi, my cakes came out beautiful. However after it cooled down, the cake sunk in. May I know why?
Hi, perhaps you have under steamed the cakes. Insert a toothpick in the middle of the cupcakes and it should come out clean if totally cooked. Thanks
Hi Angie, thanks for the share
Can I know whether I can mix the sweet potato into the entire lot of batter then spoon into the steaming cups rather than spoon the original batter followed by the purple sweet potato batter
Yes, you certainly can. In that way, you will have the whole kuih purple in colour. Thanks
