Mix together the custard powder and the sugar in a saucepan. Ask an adult to help you use the stove top as you add a little bit of milk to the mixture as you stir.
Slowly add the rest of the milk to the saucepan and keep stirring until its all mixed in.
Heat the custard gently and bring to boiling point whilst still stirring it.
Reduce heat and simmer for 2 minutes until thickened.
Let the custard cool.
Pour some biscuit in the base of a clear cup and pour custard on top.
Put a bit more biscuit base at the top of the cup to make it look like sand, stick some gummy worms into the sand.
