The Ultimate Fudgy Brownies Recipe for a Perfect Crack Top

Instructions:

1. Preheat oven to 350°F (175°C). Line an 8x8 inch metal baking pan with parchment paper, ensuring an overhang on two sides to create a sling.
2. Combine butter and chopped dark chocolate in a heatproof bowl set over a saucepan of simmering water (double boiler). Stir gently until completely smooth. Remove from heat and allow to cool slightly until just warm, not hot.
3. Whisk the granulated sugar into the slightly cooled chocolate mixture until just combined.
4. Add the whole eggs, egg yolks, and vanilla extract. Whisk vigorously for 60–90 seconds until the mixture is lighter in colour and noticeably thicker. This aeration is key for the crackly top.
5. Sift the flour, cocoa powder, and salt directly over the wet mixture. Gently fold with a rubber spatula until just combined. Do not overmix; stop folding when only a few streaks of flour remain visible.
6. Fold in any optional chocolate chips or nuts now.
7. Pour the batter into the prepared pan and spread evenly. Bake for 30–35 minutes. The edges should be set, and a toothpick inserted near the centre should pull out with moist, fudgy crumbs.
8. Allow the brownies to cool completely in the pan on a wire rack (a minimum of 2 hours is crucial) so that the fudgy structure can fully set up before slicing.
9. Use the parchment paper sling to lift the slab out of the pan. For the cleanest cuts, use a large, sharp knife dipped in hot water between each slice.
