A FBCT is a way to trace a design with icing and after it freezes can be transferred to a cake. This is great because it doesn't require drawing freehand on a cake (can we say anxiety attack?) and you can also make it a day or two in advance and keep in the freezer until you need it.
I was actually pretty worried that it wouldn't work or that it would be incredibly difficult. I was wrong on both accounts: It was one of the fastest cakes I've ever decorated with some pretty impressive results.
I won't hash out all of the details, but I will post a link to some great instructions that I found very helpful on Cake Central:
Some tips I would want to share:
1) Definitely purchase a tube of Wilton black icing along with a #2 Wilton icing tip (very small circle) and coupler. This will probably put you back about $5-7, but it will give you a cleaner image and will be the biggest investment for the project. Plus, the tubes last a long time so you can reuse it for more projects.
2) I just used canned frosting to fill in the image instead of making my own FBCT icing. I guess the benefit of making your own is that the fat content is so high that it doesn't stick to the wax/parchment paper, but I found that the generic canned stuff worked just fine.
3) After filling in the color to the image, gently but firmly tap the image a few times on a flat surface to help remove air bubbles in the icing. I didn't do this and ended up with little air bubbles in the image - not a big deal, but it would have helped clean up the finished product.
4) When you are done tracing/filling in your FBCT image, be sure NOT TO SKIP re-covering your image with more white icing (or whatever color is going to match your cake), and be sure that the extra icing extends a good 1/4 to 1/2 inch past your image on all sides. The edges of the transfer will stick a little and this will keep you from distorting the image that you just worked so hard on.
Good luck! I would love to hear if you try your own transfers!
