I am planning on attempting this cake for my sons birthday
I have never used fondant before. I need to start early on this cake. I want it to be a surprise so I will have to work on the fondant car and people when he isnt around. His bday is about 3 weeks away if I make them can i put them in an airtight container for 3 weeks or so?
I am planning on using wiltons or fondarific fondant.
Yes. you can make them ahead of time. I use Wilton fondant for figures. It dries hard and is much cheaper (especially if you can use a coupon) than fondarific. I would NEVER use it if it were going to be eaten. UCK!! Good luck on your cake and happy birthday to your son.
I use Wilton for figures, too. It's stiff enough to work with and dries pretty quickly. You can make these in advance, but don't put them in an airtight container if you want them to harden. Just cover them lightly with a paper towel or something so they don't get dusty. They need air to dry. Good luck, that's a really cute cake!
