Place the butter in an electric mixer and beat until light and fluffy.

Caramel Sauce Method

Place the sugar and water into a deep medium saucepan and slowly bring to the boil.  Make sure all the sugar has dissolved before it boils.
Boil without stirring until the sugar start to change color, then gently swirl the pan so the mixture evenly colors to a deep golden brown.
Remove from the heat and add the cream and vanilla bean seeds.    It will bubble vigorously so be careful.
Return to the heat and cook for 1 minute, stirring constantly.
Remove from the heat and set aside to cool for 10 minutes.
Stir in the dices of butter in stages stirring constantly until the butter is melted and the sauce is thick and glossy.
Set aside to cool.
Left over sauce can be stored in the fridge in a sterilized container.

Assembly Method

Spread the last ¼ of the Buttercream over the top of the cake then drizzle the top with caramel sauce and sprinkle with chopped walnuts.
