Dense, intensely chocolatey brownies with a crackly top and fudgy, gooey centre. The foolproof one-bowl recipe that beats any box mix.

Chocolate brownies are an American baked square with a dense, fudgy texture and intense chocolate flavour. The defining characteristics are the crackly, shiny top and the moist, gooey interior — distinct from both chocolate cake (too airy) and chocolate biscuits (too firm).
One bowl, 40 minutes including cooling, and the results are consistently better than any boxed mix. They keep for 5 days and improve overnight.
A bake sale, a school event, an afternoon treat, a dinner party dessert warmed with ice cream, or simply because.
Don't overmix once flour is added. Don't overbake — moist crumbs on the skewer is the target. Cool completely before cutting.
The quality of the chocolate determines the quality of the brownie. Use a bar you would eat on its own. Higher cocoa percentage produces a more intense, less sweet brownie.
The additional yolk contributes fat and lecithin, which produce the dense, fudgy texture. It also helps create the glossy, crackled top.
Used alongside the melted chocolate to double the chocolate intensity without adding more fat or sweetness.
Replace 50g of flour with ground almonds for a richer, slightly denser brownie. Use coconut oil instead of butter for a dairy-free version. Add 1 teaspoon of espresso powder to intensify the chocolate flavour without adding coffee taste. Swirl 3 tablespoons of peanut butter through the batter just before baking.
Preheat the oven to 180°C (fan 160°C). Line a 20x20cm baking tin with baking parchment, leaving an overhang to lift the brownies out. Melt the chocolate and butter together in a heatproof bowl over simmering water, or in the microwave in 30-second intervals. Stir until smooth. Set aside to cool for 5 minutes.
Stir the sugar into the warm chocolate mixture. Beat in the eggs and extra yolk one at a time, then add the vanilla. The mixture should become glossy and slightly thickened.
Sift the flour, cocoa powder, and salt into the chocolate mixture. Fold gently until just combined — stop as soon as you can no longer see dry flour. Fold in the chocolate chips if using.
Pour the batter into the prepared tin and spread to the edges. Bake for 22–25 minutes. The top should look set and slightly crackled; a skewer should come out with moist crumbs (not wet batter, not clean). For fudgier brownies, remove at 22 minutes.
Leave to cool completely in the tin — at least 1 hour. Lift out using the parchment overhang. Cut into 16 squares with a sharp knife, wiping the blade between cuts for clean edges.
Techniques that separate good from great
Instead of simply melting the butter, cook it in a light-coloured saucepan over medium heat until it turns golden and smells nutty — about 5 minutes. This is browned butter (beurre noisette). It adds a toasty, complex flavour that takes the brownie from good to extraordinary.
Day-old brownies kept in the fridge overnight are denser, fudgier, and more intensely chocolatey than freshly baked ones. The texture firms up in a way that improves the eating experience considerably.
Different ways to make this dish your own
Swirl 4 tablespoons of thick salted caramel sauce through the batter before baking. Sprinkle sea salt flakes over the top.
Warm 4 tablespoons of smooth peanut butter until pourable. Drop spoonfuls over the batter and swirl with a skewer.
Use dark, milk, and white chocolate chips in the batter. Each type melts at a slightly different rate, creating pockets of different sweetness and texture.
Perfect pairings to complete the meal
A warm brownie with a scoop of cold vanilla ice cream is a classic American dessert combination.
The sharpness of fresh raspberries and lightness of whipped cream balance the dense richness of the brownie.
A chilled brownie eaten cold is a different experience — denser, more fudgy, and intensely chocolatey.
