I made this graffiti cake for a son’s 17th birthday. It’s a full sheet, that I baked, let cool, crumb coated and then final iced with the desired, ‘brick’ color icing!
After the cake crusted over, I applied the brick design simply adding lines with tip #3, over the entire cake. I then added the graffiti by simply mimicking the font I found online. I decided to add the outline and shadow for more of an effect. The barbwire around the edges was tip #2, cris-crossed then with an X in middle. The shell border around bottom edge was with tip #21!
The cake was huge hit, was kinda nervous about the graffiti, but I was satisfied!
