This really is the perfect holiday dessert because it only needs a tin and the ingredients are easy to get hold of, every shop abroad or in the UK will have their own selection of biscuits that you can use for this lovely Hedgehog slice.
450g dark chocolate (70 %)
150g icing sugar
3 egg yolks
1 pack squared vanilla biscuits (about 25-30 biscuits)
Melt the butter in a small sauce pan, and once it has cooled a little add the chocolate and mix until the pieces of chocolate have melted.
Add the icing sugar and egg yolks and stir until the mixture is nice and smooth.
Line a rectangular bread/loaf pan with clingfilm.
Pour a thin layer of the chocolate mixture in the bottom of the pan.
Cover the chocolate with a layer of biscuits, and then add another layer of the chocolate.
Continue until you don't have any more chocolate. Remember to finish off with a layer of chocolate.
We add slaty peanuts or pistachios, but do as you prefer.
Cover the bread pan with some aluminum foil and place it in the fridge for minimum 6 hours. The chocolate should become solid.
Take the chocolate cake out of the fridge 10-15 minutes before serving it - then it is easier to cut.
