Yam Cake

As you can see this is not a chinese steamed yam cake. It is a layered sponge cake filled with yam. I found this recipe from Carol's book and her blogs and she made this into a swiss roll instead.

I added some yam puree into this sponge cake and as a result the cake is soft and moist and it gives a light aroma after baking.

If you can read chinese, you can also refer to Carol's blogs for her recipe.

• 2) Place the 2nd layer sponge cake on the filling, then top it with the filling again. 
• 3) Place the last piece of cake with the baked side downward,  please refer to my photo below.
