Chocolate Chunk Cookies

I took this recipe from a free booklet in The Guardian 2007, the original recipe listed double-quantities, but I've reduced it as I can only manage to bake 12-13 of these at a time with my baking trays.

• 112g unsalted butter
• 190g light soft brown sugar
• 25g caster sugar
• 1 1/2 teaspoons vanilla extract
• 1 egg
• 175g plain flour
• 1 teaspoon bicarbonate of soda
• 25g cocoa powder
• 150g broken chocolate pieces

Oven temperature 170°C (150°C for fan-assisted)

1. Beat together butter, brown sugar, caster sugar & vanilla extract until light and fluffy (save time and whack it in a food processor).
2. Add the egg.
3. Sift the flour, bicarb and cocoa powder together and add to food processor (or bowl, if you're feeling strong fore-armed).
4. Stir through your chocolate chunks.
5. Prepare a baking tray (cover in greaseproof paper, or grease it)
6. Scoop ice-cream scoop sized blobs onto the tray, spaced evenly apart.
7. Cook for 12-14mins until puffed up and coloured at the edges.
8. Remove, cool & eat!
