Preheat your oven before you start and set it to 180ºC, or reduce it to 160ºC for a fan oven.

Grease a medium to large baking try or roasting tin.

Soften the chocolate by putting it into a microwave for a few minutes, or on the hob as a plate on top of a pan with water in it, similar to a bain marie method of softening the chocolate.

Add all the ingredients into a mixer if you have one, or a large bowl. Mix them all together for several minutes, until the mixture is smooth.

Pour the smooth mixture into the baking tray and bake for 40-45 minutes. The brownies should feel a little soft under he centre and might be a bit wobbly, but they'll harden up as they cool.
