- STEP 1
Preheat the oven to 180C/150C fan/gas 5.
- STEP 2
Cream the butter and sugars togethers. Beat in the egg and vanilla extract.
- STEP 3
Mix the flour and bicarbonate of soda and stir into the mixture. Add the chocolate chips and mix well.
- STEP 4
The mixture can be left to stand for a few hours or it can be baked straight away. Line and grease a baking tray. Place balls of dough spread well apart on the tray (multiple batches will be required!) Bake in the oven for 8–10 mins or until light brown on the edges and still slightly soft in the centre.
- STEP 5
Remove from the oven and leave to cool for a few minutes until they are firm enough to transfer to a cooling rack. They will continue to cook a small amount while they are on the tray straight from the oven so it's better to remove them sooner rather than later!
