Preheat the your oven to 180ºc/160ºc fan and line a 9″ square baking tray with parchment paper.
Melt together the butter, dark chocolate and Terry's chocolate orange in a heatproof bowl over a pan of boiling water, on the microwave for 1-2 minutes until melted. Leave to the side to cool to room temperature!
Whisk together the eggs and caster sugar for a few minutes until the colour has turned pale, is very mousse like, and is double the original volume of the amount of eggs + sugar!
You will know its done because when you lift the whisk up out of the mix it should leave a trail for a couple of seconds before disappearing!
When whisked, pour the cooled chocolate mix over eggs and fold together carefully. It might take some time, but be patient – you don’t want to knock out the air you made up on the previous step!
Once completely combined, sift the cocoa powder and plain flour on top of the chocolate mix, add the orange zest, and then fold together again – still be careful to not knock out the air!
Once combined well, fold through the chocolate orange chunks and pour into the prepared tin – bake in the oven for 25-30+ minutes
Once baked, leave to cool in the tin completely. Set the brownies in the fridge for a couple of hours for best results.
Notes
I like to stack my brownies in pictures as you can probably tell by now if you've seen my other brownies such as the triple chocolate brownies, or my peanut butter brownies, but can you blame me?! How incredible do they look.
Imagine baking these bad boys, and then having one with a giant chunk of Terry's chocolate orange ice cream, or even a chocolate drizzle... heaven. These are the best.
These brownies last for 4-5+ days once baked at room temperature, or in the fridge
