Back to the classics - Choc chip cookies

I've had quite a break from baking recently due to all sorts of excuses HOWEVER I've managed to bake these classic choc chip cookies seeing as the cookie jar was left empty for a good few weeks (although topped up with custard creams now and then). And after baking these cookies, I don't think I can part away from baking for this long again - I really do miss it :') 

Chocolate Chip cookies (for about 18 cookies)

Ingredients:
70g caster sugar
115g softened butter
140g plain flour
1 egg
1/2 tsp bicarbonate of soda
1/2 tsp vanilla essence
1/4 tsp salt
175g choc chips
70g soft brown sugar

Method:

Preheat oven to 190 C/375 F/ Gas mark 5. Beat the butter with both lots of sugar until creamy. Break the egg in and beat until smooth. Add the vanilla and mix it in.

Add the flour, salt and bicarb into the mixture, a little at a time. Stir everything together until well combined. Add in the choc chips.

Butter the baking trays. Spoon small mounds of the mixture on, leaving quite big spaces in between. Bake the cookies for 10-12 minutes until golden brown. Move onto wire rack and cool.
