  • 140g plain flour


  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.

I made a large batch in a 12"x12" tray which I had treated myself to a few weeks earlier. It had cost me quite a bit of money but the resulting brownies were wonderful. A good quality tin makes a lot of difference. I had so many compliments and I think they were the best I had ever made. A superb recipe.

I never liked the look of brownies (dry cracked looking) but cooked these for my husband. He thought they where the best he had ever had and I am completely converted if not ADDICTED delicious. I think they need 55mins cooking but could just be my oven.

Have made these loads of times now and they are by far the easiest and best flavoured recipe for brownies we've come across - a firm family favourite. Sometimes the mixture can need a little extra time in the oven approx 15 mins. Using value chocolate doesn't change flavour dramatically and reduces cost Family and friends love them and there are never any leftover - have given recipe out to countless friends

These took FOREVER (!) to cook and my white chocolate batter split quite badly and I couldn't retrieve it, therefore the mixture ended up quite grainy. They came out of the over ok though and were very gooey (possibly because I got bored of trying to cook them for longer though!)

Made this twice now - and both times I didn't need to cook it for longer. Washing up took no longer than usual, and they were absolutely gorgeous. I made the Best Ever Brownies a few years ago - they were really nice but I think this recipe is nicer!
