Brown Butter Blondies: The Method

Tap a step to highlight it, or turn on Cook Mode for large type and step-by-step focus.

1. Melt the butter in a light-coloured pan over medium heat and keep cooking, swirling, for 5 to 6 minutes until the foam subsides and the solids at the bottom turn hazelnut brown and smell nutty.

2. Pour it into a large bowl, scraping in every brown fleck, and whisk in the brown sugar. Leave 10 minutes to cool to warm — hot butter will scramble the eggs.

3. Whisk in the eggs, the extra yolk and the vanilla, then keep whisking hard for a full 2 minutes. The batter will go from grainy to thick, glossy and ribbon-forming. This is the crackly top.

4. Fold in the flour and salt with a spatula until just combined, then fold in the white chocolate.

5. Scrape into a lined 20 x 20 cm tin and level the top.

6. Bake at 175°C / 350°F for 24 to 27 minutes. The edges should be set and the centre should still wobble very slightly — a skewer comes out with moist crumbs, not clean.

7. Scatter with flaky salt and cool completely in the tin before cutting. Cutting warm blondies gives you sixteen pieces of pudding.

Worth Knowing

• A stainless or light pan for the butter, never black non-stick: you cannot see the colour change in a dark pan and burnt butter is bitter.
• Underbake rather than overbake. They firm up considerably as they cool.
• Line the tin with an overhang of paper and lift the whole slab out to cut. Cutting in the tin tears the edges.
