Step 1: Gather your ingredients
First you need a large sponge cake
I made one using the recipe described on downsizer.net
My roasting tin which is 36cm by 26cm and about 5cm deep took a 9 egg version of the above sponge mix which I made chocolate flavour. I used a roasting tin as to achieve a sensible effect with the graves the cake needed to be quite deep. When filled the tin was half to 2/3rds full and it took 1hr to cook at 180/gas mark 4. As the article says this can vary from oven to oven so I would start checking it after about 45-50minutes. When cooked it should stop making noise and a stick/knife should come out relatively clean.
You also need
100-150g Icing sugar
Green food colouring
Digestive biscuits crushed to replicate gravel
Gravestone shaped biscuits
Pink Wafer biscuits
Candy sticks to replicate bones
Supercook writing icing (You get 4 colours in small tubes for about ÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂ£2 you could achieve the same effect with coloured icing and piping bags)
Step 2: Digging the graves
I used paper to vague plan where the gravestones and mausoleum were going to go
I used a small paring knife to cut the graves out. Being fairly careful with the sponge being removed as some of it would need to be put back.
Step 3: Burying your people
Some of the removed cake was put back into the holes to allow them to be iced though one grave was left open.
