Anyhow, you’ll need:

1. 8oz dark chocolate (I use fairly cheap Tesco own 74% cocoa solids bars)
2. 8oz butter
3. 12oz castar sugar
4. 4 large eggs
5. 6oz flour

To make the brownies is pretty easy:

1. Preheat your oven to about 180°C
2. Break the chocolate up and melt with the butter.  Personally, I find it easier to do this in the microwave – pop it in for 30 seconds then stir and repeat until the chocolate is all melted.
3. While you’re doing that, put the sugar into a big bowl, add the eggs and whisk.
4. Gradually mix the chocolate into the egg and sugar mixture (keep in mind that, at this point, the mixture will start to cook so don’t take ages)
5. Gradually mix in the flour.
6. Pour the mixture into a baking tray.  I use silicon baking trays, which are flexible and non-stick; if you don’t have one of these, consider greasing the tray or using greaseproof paper.
7. Bake in the pre-heated oven for approximately 30-40 minutes (or until cooked).

Couldn’t be easier, and it makes plenty.  If you want gooier centres, then you can probably reduce the cooking time or generally tweak the ratios.  Just don’t forget to let them cool before you try to dig in!
