This year for my son’s birthday I decided I wanted to make his cake. I am not a fan of store bought cakes and I didn’t want just cupcakes this year. The only thing I wasn’t sure about was how to decorate the cake. People can make such wonderful cakes and I wasn’t sure how they did it. I certainly couldn’t free hand anything so I went digging around the internet to figure out what I wanted to do. Since I knew I would be using buttercream, I decided on trying my hand at a buttercream transfer.
I knew I wanted a Thomas the Train cake for my son. So the first thing I did was get some Thomas coloring books and pick out a picture. I settled on a page that showed Thomas straight on. I scanned the picture into my computer and printed it out. This picture didn’t require me to mirror the image, however, depending on the image you use, you will need to mirror it before printing.
Once you have your picture, tape it onto the back of a cookie sheet. Then tape a piece of wax paper over the picture. You will begin adding your icing to the wax paper. Start by outlining. If you are using black, make sure to purchase black icing. Homemade black buttercream icing tends to bleed. (need the recipe for buttercream icing? See my recipe here.)
Next, start filling in the colors you need. When filling it in, use a brush to get the icing into all areas. Then use an icing knife to smooth it out a little bit. Don’t push too hard so that you end up moving your outline around.
Then cover the whole picture in white icing and smooth it out the best you can.
Once you have your cake iced, remove your transfer from the freezer. Lifting it up by the wax paper and using your hand for support, flip the transfer onto the cake. You will need to work quickly. If the buttercream gets soft, it will not peel away from the wax paper.
If you have lettering, make sure the words are mirrored. That way they read correctly when you place them on the cake. If you have more than one transfer, like I did, make sure to only take out one transfer at a time to work with. I got my lettering out at the same time as Thomas and it thawed. So when I tried to lift the wax paper, it stuck to it. I just placed the whole cake into the freezer for about 45 minutes and the wax paper peeled right off. That is why the end of the wording looks the way it does.
