Break up the chocolate and put it in a large bowl with the butter and golden syrup.

Melt using the bowl over a pan of simmering water or in the microwave using short blasts and stirring regularly.

Once melted, leave to cool slightly for 5-10 minutes.

In a separate bowl, mix the biscuit pieces with the marshmallows.

Pour in the melted chocolate and stir well.

Pour the chocolate mixture into a lined cake tin or brownie pan.

Push the Cadbury Creme Eggs into the mixture and put in the fridge to set for at least 4 hours.

Slice and serve.
