The cookie saga continues! (And possibly ends)

Today I was reflecting. Reflecting upon my failure to bake a proper cookie. Yeah, yesterday's were okay but they just weren't good enough.
Well, I decided that this pitiful character flaw cannot go unchallenged so I tried a new recipe today.

Ingredients:
2 cups + 2 tablespoons plain all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
1 & 1/2 sticks (170g) butter, melted
1 cup soft light brown sugar
1/2 cup granulated sugar
1 large egg +1 egg yolk
1 tsp vanilla extract
chocolate chips

How to do it:
Preheat oven to 325°F/Gas mark 3
1. Combine together the flour, baking powder and salt in a bowl and set aside.
2. Combine the melted butter, two sugars and vanilla extract and beat together. Add the egg and egg yolk and beat until thick and homogenous.
3. Stir the dry ingredients into the butter/sugar/egg mixture until combined.
4. Stir in the chocolate chips.
5. Roughly shape into balls - the craggier the better - and bake for roughly 15 minutes.
6. Take out when the edges are lightly browned. You want them to look slightly underdone in the middle - they'll harden slightly upon cooling and still be soft and chewy.



I don't know exactly how many this recipe makes since I only baked one as a test run and froze the rest of the uncooked mix in logs. Since mother reads this blog I thought it best not to be gorging myself on dough. However, I would guesstimate it to make about 15 chocolatey circles of delight. (UPDATE: It makes 12 large cookies.)
And, yes, these are about as near to perfect that I'll probably ever get. They're thick and chewy and soft and pretty amazing.
I implore you to make these as soon as possible. In fact, just go and do it now. Yes, you. Make them. Make them now! And tell me how you get on (:


NOTE: The dough will seem really crumbly and won't mix together easily, but do not add more liquid! Persevere and squidge it together with your hands.
Also, the recipe specified unsalted butter + 1/2 tsp of salt. I used salted butter and also the extra salt. Possibly because I am a disgusting human being, but whatever. They taste goooood.
