Enjoy the sweetness at the first bite.....This recipe adapted from Do What i like's blog.
I love sweet potato,i usually grill or combine it with vietnamese dessert but never tried in cake before.It's a good recipe though.I used honey sweet potato instead of the normal one.Look at the melting palm sugar filling,OMG,can't wait to roll into the kitchen again!
