How to Make Mary Berry Chocolate Brownie Traybake

1. Preheat the oven to 180°C/160°C Fan/Gas 4. Grease and line the 30 x 23cm (12 x 9in) traybake tin with non-stick baking paper to prepare it for the brownie mixture.
2. Place the chocolate and butter into a large heatproof bowl. Sit the bowl over a pan of simmering water and gently melt the mixture until smooth, then stir to combine.
3. Add the sugar and eggs to the melted chocolate mixture. Mix well until the mixture becomes smooth and fully combined.
4. Add the self-raising flour and vanilla extract to the bowl. Stir gently until everything is mixed together, then fold in the chocolate chips.
