First I found a picture from one of my son’s colour-in -books that I thought would be a good design for a Ninja Turtles Birthday Cake. I then sketched the image to the size I wanted for the cake onto some greaseproof/see-through paper.
The cake was made by using Vanilla Butter Cake packet mix as I find the packet mix cakes are easier to ice than cakes that are totally home-made.
When the cake was totally cooled, I used toothpicks to secure the sketched image onto the cake and then cut out the outside edge of the design. The other outlines and details of the design were “marked” onto the cake by inserting a skewer/toothpick at close intervals along the lines of the sketched image so that the detail of the design was left on the uniced cake.
I used vanilla butter icing tinted in the appropriate colours to ice the cake. The black outline is licorice straps cut to the right length and width as needed.
