Nigella’s classic chocolate brownies with hazelnuts
Nigella’s classic chocolate brownies are the epitome of indulgence—a rich, fudgy (but also a but cake-like) baked confection. Packed with loads of real chocolate and crunchy toasted hazelnuts, these brownies are so delicious. Serve them warm with a scoop of ice cream or enjoy them on their own; these brownies are a surefire crowd-pleaser.

In case you didn’t know I’m on an ongoing baking mission to find what I consider the ‘best of’ in a range of baked treats. Baked treats that I particularly like.
I have found the best white chocolate cookie with cranberries and a variation of this recipe with macadamia nuts and dried strawberries (better). I think I have found the best chocolate chip cookie, and I am pretty certain this is one of the best chocolate cakes. The River Cafe Chocolate Nemesis has to be the best chocolate mousse cake I have eaten, so now I turn my attention to the brownie.
This is Nigella’s chocolate brownie recipe given to me by my fab foodie friend Lori so I am not too sure which book it comes from. It is simple to make and yields a big batch.

Storage Instructions for Nigella’s Chocolate Brownies
- Room Temperature Storage:
- Store brownies in an airtight container at room temperature for up to 4 days.
- Place parchment paper between layers to prevent sticking if stacking.
- Refrigeration:
- Refrigerate brownies in an airtight container for up to 1 week.
- Allow refrigerated brownies to come to room temperature before serving for optimal texture and flavor.
- Freezing:
- Wrap individual brownies tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag or container.
- Label with the date and freeze for up to 3 months.
- Thaw at room temperature for about 1–2 hours or microwave briefly to serve warm.
- Avoid Moisture:
- Always ensure the container is sealed tightly to keep the brownies from drying out or absorbing unwanted odors.
- Reheating Tips:
- For a freshly baked taste, microwave a brownie for 10–15 seconds before serving.
Recipe
Preheat the oven to 170C
- 375gm chocolate (70% couverture is best)
- 375gm butter
Melt these together in a double boiler
- 500gms castor sugar
- 6 eggs (free range large will do)
- 1 tsp vanilla extract
Whisk these all together and then add the slightly cooled chocolate mixture to this
- 225gm flour
- 200gm nuts (optional – I used roasted hazelnuts)
Fold the flour and nuts into the liquid mixture
Pour into a large lined baking tray or suitable dish (I used a 30cm x 23cm roasting dish)
Bake for 45 mins until firm to the touch
Before I can discuss the verdict, the criteria that make a perfect brownie need to be established. Of course this is completely a matter of opinion.
- TASTE – needs to taste fantastic in both chocolate and degree of sweetness
- TEXTURE – needs to have some density to it, some moisture but at the same time it must melt in the mouth
- APPEARANCE- a brownie needs to have that quintessential flaky ‘skin’
These bownies taste lovely with a perfect balance of chocolate to sugar. The texture however seemed slightly too dry for me but the mouthfeel wasnt. They melted in the mouth.
I give these the thumbs up apart from the density issue, but perhpas next time I would bake them for a slightly shorter period to deliver a chewier centre. I also think that adding extra chocolate chips and leaving out the nuts could produce a more decadent product.
The search continues.

Chocolatey, fudgy…..mmm, jus the way I like brownie!!!
Glad you made them 🙂 Her original recipe was from ‘How to be a Domestic Goddess’ and she says only bake it for 35 minutes! Never found this to be enough, so bake for about an hour but constantly check. Think its also about how your oven works with the recipe. YUMMY!
Well they certainly look freakin awesome. Can never get enough of chocolate and especially brownies. Best brownie I ever made? Epicurious’ Jamaican Coffee Brownies. (you can find ’em on my blog). Mouthwatering I tell ya.
Marisa, I remember your post on those and will defs check out in my quest for the perfect one. Thanks!
I made these brownies this afternoon placing the mixture into a ceramic rectangular dish. Wrong! I had to keep adding time to the baking (I guess because the dish absorbed a lot of the heat before cooking the mixture. Total approximately 45 minutes. Very runny still upon cutting into it. Tasty goo though. In the end I placed the dish back into the microwave and gave it several blasts … approximately 12 minutes in total. Wonderful!
Next time I will make it in a metal dish!
Hi Jill, yes, baking in ceramic is not effective and I tend to only do it for hot sponge puddings. It does however seem that it went a little too long, maybe an idea to check your oven temperature calibration via an oven thermometre. Variances in oven temp and performance is a big thing in baking. A friend of mine bakes these all the time, and for longer and gets a much denser brownie.
Thanks for sharing.
I adore this blog, I stumbed across it the other day and it is soooo good. I know you are on a mission to find a really good brownie recipe and I suggest you try Nigel Slater’s Chocolate Brownie recipe to see if that hits the mark:

Personally I love a fudgy brownie and one of my friends baked this recently and they were delicious. Maybe you can do a taste test of your own….
Hi Julia. Thanks so much for this link. I am a big Nigel Slater fan and will try this recipe next.
