• 200g butter, chopped
• 200g dark chocolate, roughly chopped
• 100g dark chocolate orange, chopped
• Zest of 1 large orange
• 4 large eggs
• 350g caster sugar
• 100g plain flour
• 50g cocoa powder
• 6-8 Oranges to Serve
Step 1 - Heat oven to 180oC/160oC fan/gas 4 and line a 10x8 inch brownie tin with baking parchment. Place the butter, dark chocolate and orange zest in a non-stick saucepan and very gently melt over a low heat, stirring every now and then, until smooth – take care not to overheat it. Leave to cool.
Step 2 - Whisk the eggs and sugar together with an electric whisk until the mixture is pale, has doubled in volume and leaves a trail when the beaters are lifted. Gently stir into the cooled chocolate mixture. Sift over the flour and cocoa, stir in, then add the chopped chocolate orange.
Step 3 - Slice the top off each whole orange and scoop the inside out. Save the fruit to eat later. Spoon the brownie mixture into each orange and place the top of the orange back on top of the mixture. Wrap tightly with foil and place in the campfire.
Step 4 - Bake until the brownie is cooked through, roughly 35 minutes.
