This recipe is taken from the Christmas Special of Nigella Bites. Nigella says: "Christmas food is the best sort of food because it's about proper, unpretentious home cooking. Feasting isn't about formality: it's about providing friends and family with good things to eat."
1.Preheat the oven to 180C/Gas 4/350F.
2.Line your brownie pan base and sides.
3.Melt the butter and dark chocolate together in a large heavy based pan.
4.In a bowl or wide mouthed large measuring jug, beat the eggs with the sugar and vanilla.
5.Measure the flour into another bowl and add the salt.
6.When the chocolate mixture has melted let it cool a bit before beating in the eggs and sugar, and then the flour.
7.Finally fold in the white chocolate buttons. Beat to combine smoothly and then scrape out of the saucepan into the lined pan. Bake for about 25 mins.
8.The brownies are ready, when the top is dried to a paler brown speckle, but the middle is dark and dense and gooey still; remember that they will continue to cook as they cool.
