I made this for my son's 3rd birthday sometime ago. It was the my first attempt and I wanted to please my son, as his dad was away working. He was very happy and excited! I followed a simple tea cake recipe from http://www.kidspot.com.au/kitchen/recipes/tea-cake-643 and followed instructions from a few websites on cutting it to form a '3'. As my daughter doesn't like icing, I melted plain Dairymilk chocolates and spread it on the cake and decorated it with M&Ms.
