I've been looking forward to trying a digger/construction cake for a while! Myles' 3rd birthday was a perfect time for it as he loves all things digger/construction! Not sure if he was more excited to eat it or play with it!! I was nervous about cutting into the cake and what chocolates to use but it was very easy in the end and effective. I made two round cakes on top of each other, then roughly ripped some of the top off and placed it on the board. I then iced it all over (it didn't matter if cake crumbs got mixed in the icing as it looked like dirt anyway). I then used crushed choc ripple biscuits to cover the 'hole' with 'dirt', added broken honeycomb and Malteasers and placed the mini construction vehicles on. The only problem was the honeycomb shrunk due to moisture being in the fridge over night, so needs to be added last minute to keep it's colour and shape.
After cutting the back of the cake off we let him play in the crumbled down bit, which he of course loved!
