If you ever wondered how to make best chocolate brownies and what ingredients you going to need to achieve this perfect chewy and gooey result we all love, olive is here to help.

This brownie recipe uses a square tin, but you can use an oblong or even round cake tin provided it is roughly the same size – just keep an eye on the brownies, you may need slightly less or more time than the recipe states.

We have provided some great ideas to make variations on the classic chocolate brownie, too, so you can get creative with your baking.
