  • 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.

I made these brownies for some realations and I was extremely dissapointed. I followed the instuctions precisely and the mixture looked great. Then I put it in the oven. It says to put it on for 30 mins. I thought this was too much so i only did it for 28mins. The brownies came out burned (i put it on 180C) and it almost fell apart. This wasted my time and im angry as my relations were looking forward to eating them.

my dad's and husband's birthday falls on the same date.. usually we celebrate it together.. but this time my dad fell sick so my parents could not come over to my place.. i could not travel too.. so we decided to make the same recipe.. that is when i came across this recipe.. both my dad and husband are great fans of chocolate..
this is when my husband came across this app called LiveAlbum..
my mom and me made the browny simultaneously.. i shared this recipe with her through phone.. i took photos of each stage of my preparation and the photos got shared as and when i took it.. Miracle!
Dad and my husband loved the browny.. keep giving us wonderful recipes..

Made these because I had everything in the cupboard...apart from buttermilk(which I never have) so I used milk with a squeeze of lemon juice. Really surprised with the result..moist and oh so chocolatey. who would've thought..mayonnaise! I also used low fat mayo.

gorgeous, was bit worried about the mayonnaise, but they turned out really well. They went down a treat with my friends

Just made these and theyre really airy and tasteless. I'll be sticking to my gooey brownie recipe!

Well what can I say... This recipe is fantastic! Can't believe it has mayo in. I was very dubious but thought what the heck, it's worth a try and am I glad I did. Now my daughter says she doesn't want normal brownies again, she wants these and for a 9 yr old to say that, speaks volumes. Will make these again.

Forgot to rate - doh!

I have made this recipe literally hundreds of times and these are the best brownies ever - highly recommended.

I also use milk with a dash of vinegar to make the buttermilk alternative and extra light mayo - never fails.

Also try Sainsburys own brand dark chocolate at around 30p/100g bar - you won't be disappointed.

Thank you for a great recipe.

Ok I've been on the hunt for a low calorie brownie for a while I changed this recipe to take out a lot of calories and it worked a treat - heres what I did.
Replaced the 150g sugar with 12tbsp splenda (i used tesco own brand)
I used 25g cadburies highlights hot chocolate powder instead of coco ( i didnt have any coco)
I used tesco lighter than light mayo ( cuts a lot of calories)
I used 1/2 - 3/4 tsp baking soda
These changes roughly cut the calories in half - the main calorie contributor to the recipe being the chocolate.
For all you keen dieters that love a good bit of brownie!

I have made other chocolate brownies in the past all gone wrong thanks

I used extra light mayo - the brownies came out a little bit more cakey than ideal (although I think my oven is more vicious than most and I probably overdid them, so will try again for slightly shorter time than suggested. The cake version was still very yummy though so no complaints anyway!

The first time I made these I beat the mixture by hand and ended up with really delicious but rather flat brownies, I persevered and beat the next mix mechanically and they turned out precisely as pictured- highly recommended recipe

truely awseome. Not much of cook so was a bit nervy and they took longer than they should have too prepare and cook but god they were worth it

Brilliant as a light but still delicious alternative to the usual stodgy variety. Nice to eat brownies and not feel sick afterwards! Easy to make, I also used the milk/lemon combination instead of buttermilk. You don't taste the mayo at all, the overall flavour is really delicious. Will be making again, is a good base to try some variations with.

Sitting here with a cup of coffee and scrummy guilt-free brownies :) super quick, super easy and super tasty. Fab recipe, thank you!

Really easy recipe! Made lovely brownies - lovely semi-bitter dark chocolate flavour. Best eaten asap! Went a little dry after a couple of days in the cake tin. I used the milk/lemon juice method instead of buttermilk and it worked perfectly.

I made these Brownies and they are the best I have ever tasted. I wasn't sure about adding mayo but it made them taste soooooo delious. I will use this recipe alot

These were lovely although lighter and fluffier and less fudgey than normal brownies. I used low-fat mayo too. I also used milk instead of buttermilk, used a squeeze of orange juice instead of the normal lemon juice to acidulate the milk, used orange juice in place of the tbsp of hot water too. I also added the zest of the orange making chocolate orange brownies! YUM! I'm about to make an orange flavoured cream cheese buttercream icing to put on the top.

Also used light mayonaise.

I have made these brownies twice now. The first time I followed the recipe to the word and found the brownies a little dry with not enough gooeyness. The second time I made them I altered a few ingredients as advised by a few others and the brownies were absolutely amazing! Tasted rich and had that chewy fudgeyness! I am dairy intolerant so I used oatmilk and a dash of lemon juice for the buttermilk, used only light demerara sugar, saved some of the dark choc chunks to add in at the end before baking, and changed the oven temp to 170 degrees (fan oven) and baking time to 24 mins.
