Ingredients
Method
- Preheat oven to 180°C (160°C fan / Gas 4). Grease and line a 23cm square tin.
- Melt the chocolate and butter together until smooth. Cool slightly.
- Whisk eggs, sugar and vanilla for 3–4 minutes until pale and thickened.
- Fold in the melted chocolate and butter.
- Sift in flour, cocoa powder and salt. Fold gently until just combined.
- Fold in chocolate chips, if using.
- Pour into the tin and spread evenly.
- Bake for 25–28 minutes, until a skewer comes out with a few moist crumbs.
- Cool completely in the tin before slicing.
Notes
Test with a skewer for moist crumbs, not a completely clean skewer — this is the key to a proper fudgy texture.
Whisking the eggs and sugar thoroughly is what gives you that classic crackly top.
Cool completely in the tin before cutting for clean, neat squares.
Cut with a hot, clean knife between slices for the neatest edges.
Freeze cut squares for up to 3 months.
