That cake looks to me as if the coloured dots were sprayed on using a stencil after the cake was iced with plain white. Fondant icing distorts very easily, I wouldn't attempt to make spotty icing and then wrap it onto a cake.
How important is it, in all honesty, that the coloured circles are actually smooth with the white? It's for your DS's 2nd birthday - he will be delighted that it is cake, and that it is colourful and has candles on it. No-one whose opinion matters is going to judge you if the circles don't segue seamlessly from white to coloured.
If you can't use a stencil method, I think that icing the cake all over in white, rolling the coloured fondant extremely thin then cutting out circles with a pastry cutter, and stuck on with a few drops of hot water, will be the closest you can get - but the circles will almost certainly stretch to ovals in the process.
Yes i do know what you mean, Lindy Smith does it in a book on cupcakes.
Guess it depends how confident you feel, do you make alot of cakes and work with fondant alot and know how to handle it well? I dont mean anything by that just tying to find out if you used to fondant or not.
It isnt easy to do you will have to be very gentle rolling them over the top as they will lose their shape and will look oblong instead of round, so much easier to cut circles out and stick on with edible glue or water even as i did for a cake i made for my grandson back last yr, pale blue cake then cut out circles in blue, green yellow and red.
If you just add the coloured fondant all you'll end up with is a pale shade of whatever colour your icing was to start with, what you need is a pot of paste colour and add with a cockail stick with you knead in, then keep adding till you get the depth of colour you want.
What cake were you thinking of making and what colour?
I am making a cake for ds2 for his 2nd birthday, I would like to know what method is used for adding coloured ready to roll icing into white ready to roll icing to give the effect that its smooth and all "as one"?
Do I just roll out the white icing, but not too thinly, add balls of red and yellow icing and continue to roll? Is it that simple?
Thanks to anyone who had understood and can help! :-)
