Preheat your oven to 160℃ (140℃ for fan ovens) and line an 8x8-inch tin with baking paper.
Melt the dark chocolate and the butter over low heat on the stove then leave it to cool for about 10 minutes.
In a large bowl, whisk together the sugar, eggs and vanilla extract using an electric whisk. Keep whisking for a couple of minutes until the mixture becomes pale and has increased in volume.
Add the melted chocolate mixture to the bowl and gently stir it in. Then add the flour and the cocoa powder and mix until well combined.
Fold in the Mars Bar pieces and chocolate chips, leaving a few for the top if desired. Then spoon the batter into your lined tin and spread it out evenly.
Bake the brownies for around 35-40 minutes until the edges are risen and pulling away from the tin slightly. There should be a very slight wobble in the middle but not too much.
Let them cool in the tin then transfer them to the fridge for at least 6 hours (but ideally overnight) to set.
Once set, cut them into slices and enjoy!
