  • 100g mayonnaise (I used Hellman's)


  1. Heat oven to 180C/fan 160C/gas 4. Pour enough water into a small pan to one-third fill it. Bring to the boil, then remove the pan from the heat. Put the chopped chocolate into a large bowl that will fit snugly over the pan without touching the water. Sit the pan over the water (still off the heat) and leave the chocolate to melt slowly for a few mins, stirring occasionally until it has melted evenly. Remove the bowl from the pan, then let the chocolate cool slightly.

  2. Meanwhile, lightly oil and base-line a 19cm square cake tin that is 5cm deep. Combine the flour, cocoa and bicarbonate of soda. Using a wooden spoon, stir both the sugars into the cooled chocolate with the coffee, vanilla and buttermilk. Stir in 1 tbsp warm water. Break and beat in the egg, then stir in the mayonnaise just until smooth and glossy. Sift over the flour and cocoa mix, then gently fold in with a spatula without overmixing.

  3. Pour the mixture into the tin, then gently and evenly spread it into the corners. Bake for 30 mins. When a skewer is inserted into the middle, it should come out with just a few moist crumbs sticking to it. If cooked too long, the mix will dry out; not long enough and it can sink. Leave in the tin until completely cold, then loosen the sides with a round-bladed knife. Turn out onto a board, peel off the lining paper and cut into 12 squares.

Have made these a few times. The first time I melted the chocolate as in the recipe but it quickly went hard and was difficult to incorporate into the other ingredients so Now I finely chop it and fold it in at the end. Used extra light mayo and semi-skimmed milk with a dash of lemon instead of buttermilk and it worked beautifully. Think I'll make some more today-Delicious!

Lovely recipe, did not have the correct sized tin so used a shallow tin 27cm by 17cm but turned out well. Will be using this recipe again I think it would be even nicer with the addition of nuts perhaps either hazelnuts or walnuts.

Another excellant recipe, Sooooooo much nicer and more edible than the beetroot brownies!!!! Thanks for the tip about semi skimmed milk and lemon juice instead of buttermilk. Made these this afternoon, kids just come home from school and demolished them.
Should have made more!!!

Made these for christmas and newyear without the topping as people had commented that it was too rich. It was really lovely and squidgy in the middle, very easy to make!

Nice brownie but perhaps not the best ever. No buttermilk here so used Laban (like drinking yoghurt) which worked well. We added chocolate chips :-)

Very nice! I added walnut pieces which worked well. These do not taste low fat at all - saying that I put 100g of dark chocolate in rather than 80g, as thats what size bar I had. Also substituted the buttermilk with cows milk and lemon juice as everyone else suggested.

Tasty and very light - perhaps a bit too light to qualify as a proper 'brownie', but none the less, easy to make and a lovely chocolate taste. I used extra light mayo and will definitely be making again.

Yum yum yum! Made these with light mayo, used milk instead of buttermilk, and didn't have any scales so had to guesstimate quantities but they came out lovely! Fudgey and dense with the lovely cracked top. Also stirred in fudge chunks that made it perhaps too sweet, but worth experimenting, and went down brilliantly - no one guessed they had mayo in, nor could they taste it when I told them!

Not a success in my house.....more like chocolate cake than brownies so will go back to my usual brownie recipe. The mayonaise worked well though.

Made these twice now and everyone loved them. Surprised when they learn they are made using mayonnaise! Trying them next with glutten free flour so my daughter can try them over Christmas.

The best brownie I have ever made and tasted!

wasn't sure that this would turn out but it was really really good!

surprisingly tasty, although I suspect the low cal was spoilt by me adding extra chocolate to the batter before baking

Just made these, they taste and smell great. I am just hoping they keep okay for two days coz I am having to make desert in advance for dinner for friends. I would not say they are like the full fat amazing brownies but as others said I would not expect this. for a lower fat one they are great though and I think I will be making these again soon.

I made these today for Children in need tomorrow - WOW!! They are the best brownies I have ever made, nobody would ever tell they are low fat!! Glad they are not going to be lurking around my house for long or I would be very tempted polish off the whole pan...! Thank you Angela!!
