We all love a brownie, but baking one that hits that perfect level of moist (sorry) can be a real struggle.  

I'm always looking for a twist on an old favourite, and to celebrate Chocolate Pudding Day on June 26, Best Foods have shared a hack you may not have thought of. 

The secret ingredient to add to your next brownie batch is - wait for it - half a cup of mayonnaise. 

"Adding mayo to your baking will give you mouth-wateringly delicious, one-is-never-enough baking. Once you've had a taste, you'll see what we're talking about!" they say. 

It sounds bizarre, but it's actually an old trick dating back to World War II and the Great Depression, when there was limited access to baking ingredients, and cooks had to get creative. 

The oil, vinegar and egg in mayonnaise are the key weapons. The Kitchn points out that the oil makes the cake tender, the egg helps the batter retain moisture, and the acid in the vinegar really brings out the chocolate flavour.

But don't just take our word for it; Best Foods have released a recipe for you to try yourself at home.
