Melt the white chocolate and the peanut butter over a low heat. Add the double cream and a pinch of salt. When the mixture is homogeneous, turn off the heat and set aside to cool for 2-3 hours until it hardens well.
Once hardened, roll the peanut butter mixture into balls and put them on a baking pan lined with parchment paper. Refrigerate for one hour.
Melt the dark chocolate and butter in a bain-marie. Dip each ball in dark chocolate and carefully place them on parchment paper. After covering all the truffles, put them back in the fridge to allow the chocolate to harden.
Melt the milk chocolate in a bain-marie. Pour the melted chocolate into a narrow tipped piping bag and decorate the truffles as you desire. Put them back in the fridge so the chocolate can harden.
They're perfect with a cup of coffee but work magic on a festive table. They are eye-catching and win everyone over with their wonderful taste. They'll be your ultimate peanut butter truffles!
