How much Fondant For Cake
Cake Decorating is fun when you have everything sorted out in advance including much cake and frosting you need as well as how much fondant you need for your cake? Here is a guide based on the shape, size, and height of the cake. Make sure to bookmark this page for future reference
This is the most common question I get asked often. It can be quite frustrating to run out of fondant just at the end of your project.
If you have made a custom color then it is almost impossible to make the exact same shade again. So, my word of advice is, always make a little more than you think you need. It’s better to error on the side of a little more than less.
This chart is an approximate guide on how much fondant you need when rolling fondant about 3/8 -inch to 1/4 inch thick or 3 mm to 5 mm. Of course, everyone will roll differently so you may end up with some to spare. If you find you are using more than the amount in the chart below is.
Of course, this is a generous guide. If I used this guide I would this amount of fondant to cover my cake as well as have some for decoration. Again, this is a good guide but not the exact amount.
So, how much fondant do I need to cover…..
