Purple Sweet Potato Chiffon

How time flies! My little girl has turned 5 years old yesterday! Seems like not long ago my little princess still rocking in my arms. Since her favourite colour is purple, I decided to bake a simple purple chiffon cake frosted with purple whipped cream ^0^ I've done a purple sweet potato chiffon before, but  the cake did not turn out quite well. The texture was fine, just that he purple tone was not as prominent as the present one I done :D Really happy with this present purple sweet potato chiffon, nice purplish pink hue without the need of adding food colouring with soft and fluffy texture! 

My first attempt to cover a 8" whole with rose swirl! I'm using a 2D wilton piping tip. The first tried was really ugly and messy that I've to scrap of the cream and re-pipe again hahaha...still look messy but glad my kids and hubby enjoyed eating the cake and 3/4 of the cake was gone last night!
