I was asked to make a cake like in this picture for a birthday party, and in addition, I need to add a message saying "happy birthday xxx". I was thinking to make a rectangular shape from white candy melt, and write on it using food marker, then have it sit on top. However when I tried, the food marker didn't write well on the candy clay. It appears the candy clay is too sticky. Any suggestions? Should I use fondant or gum paste instead? Or should I pipe using melted chocolate, which will be harder to do, I guess...
Any suggestions or advice will be greatly appreciated. Thank you all in advance.
