Covering a cake with sugar paste
When it comes to decorating a cake you need to know how much ingredients you’re going to need. One of the most important ingredients to consider is the sugar paste. Buy too much and you can always store it for next time, but buy too little and you’re stuck!
I’ve devised the following charts over the years to help me get the right quantities. So, now you can work out how much sugarpaste you need to cover a cake and a cake board too.
Most of my cakes are about 3″ tall. I roll out my sugar paste to around 5mm thick. That way it has enough give to fit over the edge of a cake without tearing. It can also be smoothed easily. If you are covering a shaped cake add at least 1.25g of sugarpaste to these quantities.

Cake boards
I cover cake boards with icing at least a week before I need to add a cake to the board. That way it has time to set really hard and won’t get finger prints when I handle it. But I’ve also recently discovered that you can pop a cake board in a warm oven to speed up the process if you’re on a tight deadline. An hour in an oven at around 50-100 C is all it needs. Leave it to cool completely before you touch the top.

Hi Emma,
Requesting you to please give the request for sugar paste or fondant? Its a special request.
Hello,
Unfortunately I don’t have a recipe to make sugarpaste. I did try it a few years ago and it made a big lumpy mess so I now buy it ready to roll. Sorry

Hi Emma , wonder If you can help . I’m making a number 18 cake & trying ( and failing ) to figure out how much sugarpaste I need . I measured them both ( using string & measuring tape ) at the widest point and down the sides and the 1 measures 15″ and the 8 23″ ……. Any tips on figuring out how much I’ll need ??
Thanks
Claire
I would do the sides first ie the 1 say to cover a board is 1kg so use for the sides and the top you may need a bit less ie for the 1 top say 750g and the eight more sides so try 1 1/2kg and same on top hope this helps
Thanks Tina
