Ingredients

  • 200g dark chocolate (70% cocoa)

  • 140g plain flour

Method

  1. Butter and line a 23cm square brownie tin (or a similar size rectangular tin) and heat oven to 180C/fan 160C/gas 4. Put the dark and white chocolates into two separate large bowls and add half of the butter to each. One bowl at a time, heat in the microwave on High for 1½ mins, stirring halfway, until the chocolate and butter are both melted. Alternatively, melt over a pan of simmering water (making sure the water doesn’t touch the base of the bowl). Stir until the chocolate and butter are totally incorporated.

  2. Add 150g sugar and 2 beaten eggs to each bowl, then beat until smooth. Now stir 50g of the flour into the dark chocolate mix and the remaining 90g into the white mix.

  3. Spoon tbsps of the batter into the tin, alternating dark and white chocolate to make a patchwork pattern of blobs. Once the bottom of the tin is covered, go over the first layer, spooning white on top of the dark blobs and dark on top of the white. To marble the brownies, pull a skewer through the pan several times to make feathery swirls.

  4. Bake for 35 mins or until the middle of the brownie is just set and the white chocolate patches on top have a pale golden crust. Leave to cool completely in the tin before cutting into 16 squares. Will keep in an airtight container for up to 3 days, or freeze for up to 1 month.

Such an amazingly moorish recipe! We make this at every get together with friends and it all goes within minutes - no chance of keeping it for up to three days as suggested!

Am just about to give these a go but since they take a long time to cook I am going to tr something I came across by accident or perhaps by the devine intervention of some god of chocolicious ecstasy............... If ever a brownie recipe is going to take over 25 minutes to cook, I add a handful of roughly chopped werthers originals. Not the soft kind. Honestly they sort of turn into fudge lumps that melt. Dont know what they will be like after an hour tho, will report back.

I would agree that the brownies took a bit longer to cook than specified in the recipe but the result tested very good. I have made normal brownies before and the white chocolate mixture was a nice change. Although the white chocolate mixture does brown on top a little, when cut the brownies still look more impressive as you can see the different colours on the sides.

This was easy to make, although I did have a slight accident the first time, when I added 350g of sugar to the white chocolate mix, instead of 150g. However, when I managed to make tese with the correct amount of ingredients, the recipe was easy, and the finished brownies were gorgeous

having three chocoholics in the household i am always looking for new rescipes and these hit the spot. i didn't have any problems with the white chocolate and would certainly bake them again. already printed out the rescipe for three people and only made them yesterday!. i rate these next to gary rhodes bourbon biscuits. so if you really enjoy your choc try the bourbons next, you wont be disapointed. alot of messing around but OUT OF THIS WORLD. these are good to tide you over though.

I made this for a family gathering, and served it as dessert with some single cream containing melted white chocolate. Thumbs up all round, including from some very fussy eaters! My husband got to taste it beforehand and thinks its a fantastic recipe. He isn't a great fan of desserts but loves chocolate, and this definately hit the spot. I did look at other readers comments before making this recipe, and agree that is was difficult to get the white chocolate sections to set. I ended up cooking it for about 15 minutes extra, at which point it was still rather gooey when it came out, but once it had cooled it did set well enough. I had to make them a week in advance, so popped them in the freezer. Having tasted one freshly made and one that had been frozen, I can say that they freeze very well, I couldn't tell the difference.

I made these brownies on a whim one rainy day, not being a huge fan of chocolate, and they were divine! I used goat's butter and wheat-free flour, and they worked perfectly, and I had no trouble with the white chocolate turning darker. They did take almost an hour to cook, but well worth it! Call it beginners' luck, but they were great!

Although these were very tasty they are a bit time consuming , create lots of washing up and as already said do not cook in allocated time. Unless you really!!! want white choc brownies (go dark on top when cooked anyway) I would try the "best ever brownie" recipe on this site, they taste just as nice if not better and cook in time shown, so no guess work required.

These are really easy to make and taste absolutely delightful. All the family loved them and we are making more. They have a lovely firm outer and when you bite in you get a lovely soft tasty centre. I used olivio instead of butter and although I thought I had gone wrong with the mixture (very loose) they turned out wonderful. My first attempt at making brownies and a hugh success. As stated took slightly longer to cook.

Tasted fine once they were done, but its a lot of mess and fuss for a brownie-and you cant tell the different chocolates apart once its cooked(It DOES take longer then the cooking guide)as the white chocolate browns.

Also, when i melted my white chocolate it refused to bind in anyway with the butter and just became a greasy lump-i had to drain off the excess butter and really beat the mixture before it was half-useable.Dont quite know what went wrong as the dark chocolate was fine.

Much prefer the Brownie Cake recipe from this site-its easier and a lot less mess!!!xxx

This is one of the best brownie receipes I have ever used! They are really dense and chocolatie, but still have that crispy topping...also they are very easy to make!

Very good, everyone at work loved them. Also had to cook them for longer, which meant the white sections became quite dark. Next time I'll use a shallower dish (or 2), so they cook quicker.

These went in a heartbeat. I used a milky bar for some reason and everyone loved them.

Very taste, chewy and moist, made these and everyone loved them. However think I put on 1/2 a stone that week, but totally worth it. Next time may try adding some pecan nuts for a crunchy texture. Also had to cook for longer than specified.

I had to cook them for longer than it said in the recipe but I will definately make these again, I might even try them just with the white chocolate!

Made these to take along to a triathlon event that I did with my husband and a couple of friends. Bit of a faff and creates a fair bit of washing up but definitely worth it!
