Preheat your oven to 180C/160C 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!
Using an electric whisk/stand mixer, whisk together the Eggs & 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 30-35 minutes! Once baked, leave to cool in the tin completely.
Do not replace the dark chocolate in the brownie batter with milk chocolate - it's important to use the Dark Chocolate.
If you can’t find Terry’s Chocolate Orange anywhere for the chunks, then use 200g Dark Chocolate in total for the brownie batter.
Use Milk Chocolate Chunks to fold through, with an extra orange zested.
Warm these up in the microwave and serve with some ice-cream, a delicious dessert for any occasion!
Depending on your ovens, or how you mixed the brownies up, some can take up to an hour to bake successfully. I’ve never fully understood why, but don’t give up if they’re not done after 35 minutes – cover with foil and continue to bake for longer. I poke a skewer through them and wait till its mostly clean, and the mixture doesn’t wobble in the tin.
These will last in an airtight container for 1-2 weeks!
RECIPE UPDATED FEBRUARY 2019
It used to be 200g Dark Chocolate for the brownie batter, and bake for 25-30 minutes - other than that, I haven't changed anything else.
