How do I make it?

  1. Prepare the pan

    163°C

    Line the pan, put an oven rack in the lower third and heat the oven to 163°C.

    A baker lines an empty square pan with parchment.
    Leave a parchment overhang to help lift the cooled slab.

    Ready when: Lower-third rack.

  2. Melt the butter mixture

    Gently heat the butter, sugar, cocoa and salt together until the butter melts. Let it cool briefly until warm rather than hot.

    A bowl of cocoa mixture sits above a saucepan as the butter melts.
    Warm the butter, sugar and cocoa gently over simmering water.

    Ready when: Warm, not hot.

  3. Add the eggs

    Stir in the alcohol-free vanilla, then beat in the eggs one at a time until the mixture is thick and glossy.

    Ready when: Thick; glossy.

  4. Add flour and nuts

    Stir in the flour until you can no longer see it, then beat the batter about 40 strokes. Gently stir in the nuts if using and spread the batter in the pan.

  5. Bake until set

    20–35 min or longer

    Start checking the brownies early and give them more time if needed. They are done when set and a tester comes out with moist crumbs, rather than wet batter.

    Ready when: Set; tester has moist crumbs.

  6. Cool and slice

    Let the brownies cool completely. Chill them before cutting if you want neater slices.
