Hello,
Feel free to take a look at my cake on the GBBO website, if you 'like' it then feel free to click the button
.
It was a wedding cake for two doctor friends of mine who wanted something fun for their wedding but without loosing too much of a traditional edge. When the heart was pulled out the nose lit up and a buzzer sounded! I was really pleased with it- it's all edible other than the bulb nose and the wires (they went through straws through the cake)
here it is!
