These chocolate brownies with mayonnaise are rich, gooey, and deliciously simple. At first glance it seems an odd combination, but the main ingredients of mayonnaise are eggs and oil so it makes perfect sense.
Chocolate brownies are a winner in two ways: both delicious, and versatile. We have them as a snack on their own, or as pudding at the end of a meal with a scoop of ice cream. They’re simple to make, too. Compared to the split second timing and large dollop of luck involved with making a chocolate fondant, these chocolate brownies with mayonnaise are very straightforward, but still gooey, rich, chocolatey and delicious.
There are no real tricks required with this recipe. Mix the dry ingredients: the flour, cocoa powder, and baking powder. Whisking the eggs, vanilla, and sugar doesn’t call for fine judgement; just use electric hand mixer and after a couple of minutes the mixture will be a bit thicker than when you started – don’t worry too much about exactly how much.
If melting chocolate in the microwave, it does take a tiny bit of care; zap it for 20 seconds or so, see how it’s getting on and then give it another go. It’s better to have a few solid lumps of chocolate left that you can melt with a bit of stirring rather than overdo it with the microwave.
Then just fold all the ingredients together, pour into a lined cake tin and bake. The test for whether they’re done is the same as a cake – poke a cocktail stick or skewer into the middle, and the brownies are ready if it comes out clean. Allow the brownies to cool before cutting them into squares.
The surprise ingredient of mayonnaise does make a difference. The brownies don’t taste of mayonnaise, but adding it does result in a rich and gooey result, which is exactly what we’re looking for in this chocolatey treat. We take care to make sure that we use mayonnaise made with free range eggs: most of the quality brands are, so for us it’s worth spending that little bit more over a budget offering. This isn’t all you can do with mayonnaise, though. There are plenty of other unexpected ways a dollop can help around the house.
5 more unexpected uses for mayonnaise
- Removing a too-tight ring from a swollen finger. Massage mayonnaise into your hand, and the ring should slip off.
- Remove sticky adhesive residue left behind by labels or price stickers. Rub some mayonnaise over the sticky patch and remove with a clean cloth. This also works for tree sap if you’ve parked a car under a tree.
- Clean crayon marks from walls, if children have been a bit enthusiastic with their colouring in.
- As a manicure treatment to improve nail strength.
- Treating head lice. A non-toxic remedy: cover the hair with mayonnaise and leave overnight. Don’t use a low fat mayonnaise here. Use a disposable shower cap while sleeping to protect the bedding, and wash out in the morning.
After all that, you’ll need a treat. Time for another brownie!
