Thought I'd jump on the Guinness bandwagon whilst also celebrating the Kentish Cobnut (in season now). You can substitute other nuts. Hazelnuts are similar. You could also substitute the Guinness with any dark beer (though @classic33 might not approve). 150g Plain flour (APF) 80g Cocoa 220g 80% dark chocolate 90g Butter 120g Dark muscovado sugar 4 beaten Eggs 225ml Guinness 150g roasted and chopped Cobnuts You need a square brownie tin (9 inches) lined with cooking parchment. Pre-heat your oven to 170˚C (325˚F or gas mark 3) Mix together the cocoa powder and flour (sift if you want, I don’t) Break up the chocolate. Place in a glass bowl with the butter, melt over a pan of simmering water (I just melt in a bowl in the microwave) Add sugar to the melted chocolate and stir. Add the eggs gradually whilst stirring Add the Guinness and then fold in the flour and cocoa powder. Add half the nuts to the mixture. Pour mix into tin & sprinkle over the rest of the nuts. Bake for 25-30 mins. Cool in tin and turn out. Divide into 8 pieces.
