I used a combination of everybody's recipes LOL.

Base:

125g Melted Butter
250g packet Marie Biccies

Middle Layer:

1 tin condensed milk
1/3 cup lemon juice
2tsp gelatine dissolved in 1 tbsp boiling water.

Jelly layer:

Raspberry Jelly prepared as per the packet instructions.

YUM. Funny I don't normally like jelly (neither does Jacob funnily enough!) but I do like it on this! I might give him a little treat later if he's a good boy and see if he likes it!
