Mix the flour, butter, sugar and baking powder together with the beaten egg in a food processor.
Press into a greased pastry case or baking dish.
This pastry is very soft, but crisps up beautifully once cooked.
FILLING
Melt the butter and sugar until the sugar is dissolved. Add the milk, and vanilla essence and boil until a very light golden brown. This should take approximately 12 minutes in total, stirring constantly so that the mixture does not boil over.
Sprinkle the raw nuts over the pastry and pour the filling over the uncooked pastry and nuts.
Bake at 180ÂșC for 30 minutes. The filling may bubble over, so to avoid mess, place a roasting pan on shelf below your tart tin.
Allow to cool and then remove from the tin.
Sprinkle with icing sugar once cooled.
