If you love brownies with a crackly top and a rich, fudgy centre, these Nigel Slater chocolate brownies are hard to beat. Adapted from a recipe in The Kitchen Diaries: A Year in the Kitchen, they are deeply chocolatey, gloriously gooey and surprisingly easy to make — the sort of bake that earns a permanent place in your recipe collection.
There is a lovely simplicity to them, too. No complicated extras, no unnecessary fuss, just good chocolate, butter, sugar, eggs, flour and cocoa coming together in exactly the right way.
The result is everything you want from a really good chocolate brownie: a thin, glossy crust on top, a dense and chewy middle, and that intensely chocolatey flavour that makes them impossible to stop at one square. They’re ideal for birthdays, weekend baking, bake sales, afternoon tea, or those days when only a proper homemade brownie will do.
I first made these brownies to celebrate a personal milestone, and they’ve remained one of my favourite chocolate bakes ever since. This is a recipe worth returning to again and again, whether you serve them slightly warm as a dessert or keep a tin on the counter for sneaky chocolate moments with a cup of tea, much like these World Peace cookies.
Nigel Slater describes these as “No nuts, no flavourings, just a 24-carat brownie recipe, as dense and fudgy as Glastonbury mud.” It is a gloriously vivid description, but also an accurate one. These brownies are all about deep chocolate flavour and that soft, fudgy middle that makes a really good brownie so hard to resist.
There is a reason Nigel Slater’s very good chocolate brownies have become such a favourite with home bakers. They strike that ideal balance between a glossy, delicate top and a dense, fudgy middle, with a deep chocolate flavour that feels rich without becoming overly sweet.
What makes them so appealing is the balance of texture and flavour. Just butter, chocolate, sugar, eggs, cocoa and a little flour come together to create a brownie that feels reliably indulgent, whether you bake it for a celebration, a weekend treat or simply because the chocolate craving has won.
The beauty of this brownie recipe lies in its simplicity. Most of the ingredients are basic baking staples, but because there are so few of them, each one earns its place.
Dark chocolate gives the brownies their deep, intense flavour, while cocoa powder adds even more chocolate richness. Butter and golden caster sugar create that soft, decadent texture, while the eggs help give the brownies their glossy top and gentle structure. A small amount of flour, along with a little baking powder and salt, brings everything together without taking away from the dense, fudgy finish.
As with many straightforward bakes, quality matters here. Good chocolate will give you a better depth of flavour and a more luxurious result.

These rich, fudgy chocolate brownies have a crackly top, a dense centre and an intense chocolate flavour. They’re easy to make and perfect for anyone who loves a proper gooey brownie.
Prep time: 25 minutes
Cook time: 35–40 minutes
Total time: 1 hour
Yield: 16 squares
300 g golden caster sugar
250 g butter
250 g dark chocolate, with 50 g chopped and set aside
3 large eggs, plus 1 extra egg yolk
60 g plain flour
60 g cocoa powder
½ tsp baking powder
Pinch of salt
1. Preheat the oven to 180 °C. Line a 23 cm × 23 cm brownie tin with baking paper.
2. Beat the sugar and butter together until light and fluffy.
3. Melt most of the chocolate in a heatproof bowl set over a pan of barely simmering water, making sure the bowl does not touch the water. Stir until smooth, then remove from the heat. Keep the remaining 50 g chocolate chopped and set aside.
4. Lightly beat the eggs and extra yolk together. Sift the flour, cocoa powder, baking powder and salt into a separate bowl.
5. Gradually mix the eggs into the butter and sugar mixture. Fold in the melted chocolate, followed by the reserved chopped chocolate.
6. Gently fold in the dry ingredients, taking care not to overmix.
7. Spoon the batter into the prepared tin and smooth the top. Bake for 35 to 40 minutes, until the surface is set but the centre still feels slightly soft.
8. Leave to cool in the tin before slicing. The brownies will continue to firm up as they cool.
Baking tip: For the best fudgy texture, avoid overbaking. The centre should still have a slight wobble when the brownies come out of the oven.
These brownies are excellent on their own, cut into neat squares and served with a cup of tea or coffee. If you want to dress them up a little, try serving them slightly warm with vanilla ice cream, crème fraîche or a handful of raspberries. They also make a very good dessert for sharing, especially when you want something simple, comforting and unapologetically chocolatey.

The secret to really good chocolate brownies is knowing when to stop. Overbaking is the quickest way to lose that soft, gooey centre, so it is worth checking the tin a little early. The top should look set and slightly shiny, while the middle still feels just a touch soft.
It is also worth resisting the urge to overmix once the flour goes in. A gentle hand will help keep the texture dense and tender rather than heavy.
And finally, let the brownies cool before slicing if you can bear to wait. They will continue to set as they cool, which makes all the difference to that perfect fudgy texture.
Once you’ve made these Nigel Slater chocolate brownies the first time, it’s very easy to make them your own. The base recipe is rich, fudgy and deeply chocolatey, which means it lends itself beautifully to a few simple twists.
For added crunch, fold 50 g of chopped walnuts or pecans into the batter before baking. The nuts bring a little texture to the soft centre and work especially well if you like a more classic chocolate brownie.
If you’re partial to the combination of chocolate and peanut butter, swirl 2 tablespoons through the mixture before it goes into the oven. It adds a gently savoury note that balances the sweetness and makes the brownies feel even more indulgent.
For a brighter, slightly more fragrant finish, try adding a little finely grated orange zest to the batter. A few raspberries scattered over the top can also work well, particularly in spring and summer, though it is best not to overdo them as they can add extra moisture.
To make the recipe dairy-free, swap the butter for a good vegan alternative and use a dairy-free dark chocolate with plenty of cocoa flavour. As ever with simple bakes, the better the ingredients, the better the result.
If you enjoy putting a twist on a classic brownie recipe, you might also like my KitKat brownies for something a little more playful and indulgent.
Keep the brownies in an airtight container at room temperature for 3 to 4 days. This helps them stay soft and fudgy without drying out.
Yes — brownies freeze very well. Once cooled, slice them and freeze the pieces individually or in layers separated with baking paper. They should keep for up to 2 months. Defrost at room temperature before serving.
You can prepare the batter a day in advance and keep it covered in the fridge until you are ready to bake. Give it a gentle stir before spooning it into the tin.
Because this is such a simple recipe, the chocolate makes a real difference. Choose a good-quality dark chocolate with a rich cocoa flavour for the best results.
These brownies have a dense, gooey texture because the recipe uses only a small amount of flour and plenty of chocolate, butter and sugar. The key is not to overbake them, as they will continue to firm up as they cool.
If you are after a reliable chocolate brownie recipe that delivers every time, these Nigel Slater brownies are well worth keeping in regular rotation. Rich, chewy and properly chocolatey, they are exactly the sort of bake that disappears fast and gets requested again. And if you are in the mood for more comforting bakes, my browned butter chocolate chip cookies are another easy favourite.
