When my 2nd daughter was born we decided to design her room in Tinkerbell, so it only made sense to do her first birthday cake as a Tinkerbell cake.
I used a 9×13″ pan, found a cute picture of Tinkerbell on the internet and printed it out. I then traced the picture on to my cake and mixed up the colours to match the picture and piped the picture with decorating icing.
You need to put a thin layer of white icing on the cake first and freeze it for a good 24 hours, after that trace your picture you like (this can be difficult for the icing starts to melt so you may need to freeze it part way through)on the cake and out like the picture in black icing and then fill the rest in one colour at a time.

Hello. This cake looks fab and I was wondering how you traced the image onto the cake as it has been done so well!
All I did was print the picture from the internet about 3 copies, traced the picture on wax paper with a pencil, or I would use paper, then once the cake is frozen, put the copy on the cake, try not to rest your arm on the cake. Icing melt past you you have to keep checking to see if the paper is stuck to the cake, before it gets stuck stick the whole thing back into the freezer.
how exactly did you transfer the image to the cake to know where everything goes
I have done a Dora cake similar to this, to get the picture on the cake I iced it with plain butter cream then put in fridge to set, then place the picture on the cake (normal paper) then go around the whole outline with a pip, peel it off then do dot-to-dot with your piping bag & line tip. :) comes out PERFECT every time (I have attempted to upload the pic & instructions on here but it didn’t work)
