Purple Sweet Potato Chiffon Cupcakes 紫薯戚风杯子蛋糕

As I said, this blog is to archive food that I cooked for my little boy. Everything written here are genuine.. To be frankly to all, this is my first time EATING sweet potato chiffon cake! No kidding... I never see any store or bakery selling this cake. I only got the idea from google when I have a big packet of purple sweet potato sitting in my fridge that taking up too much space. 

Before this, I couldn't imagine how would it taste when a chiffon cake added with sweet potato. I made pandan chiffon, orange chiffon and lemon chiffon before, but my boy only like pandan chiffon. Now, this is the new flavor that he likes :) but he said he didn't like the 'grey color'...sigh...I was a little regret didn't add lemon juice to make them looks pinkish, but after I added the lemon juice, he may not like them....so, what should I do next time???? hmm...with some toppings maybe?

These cakes doesn't looks good to me... After I take them out from the oven, I don't even bother to try it and I went out straight to pick my boy. Until when we were back home, my boy ran to his table (where I put the cakes on the rack for cooling), he bite one of it and tells me 'mommy, it's good you know!' ...I ate 4 of them right after and while eating them, I took some snapshot of the cakes...just to show off how ugly are they!!! hahaha....but they are yummy..moist and soft....best when chilled. However, the pandan chiffon cake is still unbeatable!
