After extensive, mouthwatering research I decided to make them following a recipe from the amazing Smitten Kitchen blog (American-version recipe is here). They came out very fudge-y, with a thick, rich texture and a nice hardened crust. They aren't quite as chocolatey as I would have liked, although I am used to quite bitter, more English-style brownies. Even my mum ate more than one!
Recipe, adapted from Smitten Kitchen:
170g dark cooking chocolate
150g plain flour
1/2tsp baking powder
425g caster sugar
1tsp vanilla extract
Pinch of salt
- Preheat the oven to 160oC and line a 9in x 9in baking tin with greaseproof paper.
- Melt the chocolate and butter together in a large bowl over a pan of almost-boiling water, stirring occasionally, until smooth.
- Combine the flour, baking powder and salt in a small bowl.
- When the chocolate and butter is fully melted, whisk the sugar into the chocolate mixture. Add the eggs, one by one, and the vanilla, until fully mixed together. Slowly fold in the flour with a rubber spatula (not a whisk), being careful not to over-mix.
- Pour the mixture into the prepared tray, and bake in the oven for approximately 35 minutes. I had to turn the oven up to 170oC for the final 5 minutes, as mine didn't seem to be baking. When a sharp knife/skewer inserted into the middle of the cake comes out almost clean, they should be cooked.
- Leave to cool (or eat them straight away - no one will blame you).
