Brilliant!
We have a silicon one but if you don't line a loaf tin with clingfilm.
Melt 500g chocolate with 200g whipping cream.
Whisk 6 egg yolks with 75g of icing sugar and add a good slug of baileys (optional, add more cream if not)
Gently heat the egg and sugar mix and add the melted chocolate very slowly, stirring throughout.
Pour into the tin, lave for a couple of minutes until it starts to cool and thicken and then drop in as many minature bars as you can fit.
Put in the fridge for at least 6 hours. Slice up and serve with icecream.
