I got them from Xinying. She attended some baking classes and generously offered to share them with me. =D So thankful to her. But I am not able to share the recipe here, thou I have tweaked them slightly. You can ask me for my version if you want ya.
This butter cake is very nice, I just give "phoon huat" butter but the cake is already with very rich buttery aroma. The taste was just nice, soft and not too dense either. Thumbs up.
