I have had this recipe for years and can’t remember where it originally came from.

I wrote it into a recipe book which my mother gave me when I left home. In my neatest hand writing I wrote that this recipe “Lasts for up to one week,” but the mousse has never lasted long enough with my family to confirm that is actually the case.

180 gm chopped Mars Bars

2 Tblspns boiling water

2 eggs – separated

300 ml thickened cream – whipped

2 Tblspns caster sugar

Grease the mould and place it into the freezer while you make the mousse.

Melt Mars bars (I use the double saucepan method), stir in the water and leave to cool. Stir the egg yolks into the chocolate mixture, then fold in the whipped cream. Beat the egg whites to a soft peak, then beat in the sugar. Fold the egg whites into the chocolate mixture, then spoon into the mould and freeze.
