Earlier this week on an extremely sunny day, I made some chocolate cupcakes and decorated them with vanilla icing. The extreme brightness threw me and my lighting team (ahem, me!?) a little, so please excuse the quality of the video, but I think it shows pretty clearly where and how you should be icing to get this effect!
I used a Wilton 2D nozzle which I use for rose as well as Christmas Tree effects. This is a pretty style of piping that covers the cake with a lighter layer of icing than our standard Yummy Swirl :-) Check out the video below to see how to pipe... (all the recipes are in our book which you can buy from here www.adecadeofcake.com )
Hope you enjoy! x
