Why you (and everyone you know) will love this recipe
I’ve made hundreds of brownies over the years. And, although these might not be as quick and straight forward as easy one bowl brownies, they are SO worth the effort! It’s texture and deep, rich chocolate flavour are unparalleled by any other. No dry cakey brownies here, thank you!!!
Yes, you can always add extras to make them more stand-out (like Kinder Bueno brownies or millionaire brownies), but if you can conquer a classic chocolate brownie as is? You will be eternally rewarded! (And regularly pestered by friends and family to make more!)

Ingredients
Confused about what ingredients to buy? Not sure about a substitution? Here’s everything you might need to know…
- Chocolate – Although chocolate with a low cocoa content still tastes great in a brownie, I highly recommend using good quality chocolate. You really will taste the difference!
- Butter – You can use salted or unsalted butter, it doesn’t make a big difference in this recipe.
- Eggs – The recipe was written using large free range eggs. You may need to adjust if your eggs are particularly small or very large.
- Sugar – Dark muscovado sugar adds to the deep, rich flavour of these brownies. You can use light brown sugar instead, but it will alter the flavour a little.
- Vanilla – I always recommend using a good quality vanilla like Little Pod. Supermarket versions aren’t real vanilla, and don’t taste of anything! Don’t waste your money.
- Flour – You need self raising flour in this recipe. If you only have plain/all purpose, you can make homemade self raising flour.

Emma’s top tips
Here are tips you’ll find helpful when making this recipe.
- Read through the recipe, and prepare your ingredients BEFORE you begin. It’s the easiest way to avoid unnecessary, costly mistakes.
- If you want a ‘cleaner cut’ on your brownies, chill in the fridge before slicing into pieces.
- Lining your tin with baking paper not only stops your ultimate chocolate brownies from sticking, it also acts as a helpful handle to lift out the brownie once cooled.
- Don’t pour the batter into the tin from a great height! You will knock out all the air you spent ages putting into it. Instead, pour it from as close to the tin as possible.

Timings
Have limited time? Struggle with recipe timings? Or juggling around other things? Here’s some time managing info to make your life easier!
- Making the brownie batter will take about 15 minutes.
- Baking ultimate chocolate brownies takes 30-35 minutes.
- You need to allow at least a few hours for them to fully cool before slicing. (Overnight is a safer bet.)

(For a printer friendly version, see the recipe card at the end of this post)
Ingredients
Here is what you will need to serve 16.
Please note, this recipe includes both UK metric and US Cup measurements.
- 250g (8.8 oz) Dark Chocolate (good quality)
- 100g (3.5 oz) Milk Chocolate (good quality)
- 200g (3/4 Cup + 1/8 Cup) Unsalted Butter, Room Temp
- 3 Eggs, Room Temp
- 250g (1 + 1/4 Cups) Dark Muscovado Sugar
- 1 tsp Vanilla Extract
- 50g (1/3 Cup) Self Raising Flour
Essential Equipment
- 20cm (8″) Square Baking Tin
- Baking Paper
- Large Mixing Bowl
- Spatula
- Electric Stand Mixer or Electric Hand Whisk
- Sieve
- Wire Cooling Rack
Instructions
Preheat the oven to 190°C/Fan 170°C/374ºF. Then lightly grease and line the base and two sides of the tin with baking paper.

Next, break the dark chocolate (200g | 3/4 Cup + 1/8 Cup) and milk chocolate (100g | 3.5 oz) into pieces, and place it into a large mixing bowl with the butter (200g | 3/4 Cup + 1/8 Cup). Then heat in 10 second intervals in a microwave, stirring well after each time, until fully melted.

Now crack all 3 eggs into the bowl of an electric stand mixer with the whisk attachment (or a large bowl with an electric hand whisk), and whisk for at least 3-4 minutes on a high setting.
They should become pale in colour, and very airy.

Next add in the muscovado sugar (250g | 1 + 1/4 Cups) and vanilla extract (1 tsp) and whisk again, until evenly blended but still light in texture.

Then, in thirds, pour the melted chocolate into the egg mixture, and gently fold in using a spatula.

Once all the chocolate is incorporated, sift in the flour (50g | 1/3 Cup) and fold it in, just until you can’t see anymore streaks.

Now pour the brownie batter into the prepared tin, and bake in the centre of your preheated oven for 30-35 minutes. There should still be a little movement in the centre.

When the time is up, place the baking tin onto a wire rack to cool completely. (Don’t worry, any cracking will mostly sink in once cooled.)

Finally, allow your brownies to cool completely in the tin. (Don’t rush this stage, or things will get messy!)
Once cooled, remove from the tin, peel off the baking paper, and slice into 16 pieces.

How to store your ultimate chocolate brownies
Store your brownies in an airtight container (I prefer a metal tin lined with baking paper), and store at room temperature. Consume within 5-6 days.
FAQs
Yes! Brownies actually freeze very well. Just make sure you wrap them properly, and defrost thoroughly before eating. You can freeze them for up to 3 months.
The difference between cakey and fudgy brownies is usually down to the fat content. Brownies with a higher fat content tend to be more fudgy, and those with a low fat content are usually cakey.

I rarely comment on recipe sites but I just wanted to say, I have been making these brownies once or twice a year for nearly ten years now. Seriously, I just found an email I sent to my mum in 2015 with the recipe. They are without a doubt the greatest thing I have ever baked - you have my eternal thanks.

So I followed your recipe to a T despite having misgivings about the small amount of flour. Currently I have a liquid goop mess. What have I done wrong? We even have exactly the same pans!

Honestly? I'm not sure without knowing exactly what you did. Did you let it cool completely before trying to remove from the tin? Or even popping it in the fridge to set it a little more?

These look like the perfect chewy brownie! I have a weakness for baked goods, brownies in particular lol. If it wasn't for my love of BBQ I would have been a baker. :)
