The brown butter chocolate chunk cookies aka Crack Cookies

Tonight as I was wondering which recipe to share with you (it was between apple crumble and poached eggs), I remembered that I’d been baking a lot of cookies recently and posting photos of them on Instagram. It’s time, isn’t it. The time has finally come to share my crack cookie recipe that I’ve been promising for a while.

Top tip: Keeping cookie dough balls in the freezer are an investment in your future self’s happiness.

There are variations of that sentence around the internet and social media. That’s my paraphrase above. It is one of the reasons why I love making these cookies. This recipe will make enough so that you can store some away (like squirrels do with their nuts in preparation for winter) for a moment when you really want to eat a cookie, or bake something but have no energy for it. That was me two nights ago. I arrived home from work physically and emotionally exhausted, wanting to be fed and then to sit down with a home baked biscuit to watch episode 2 of the Great British Bake Off – Biscuit week. Fortunately I live with a family who will let me do all those things and I had frozen cookie dough balls stashed away in the freezer.

As the butter melts, it foams as the water evaporates.

I went through a phase when I was obsessively recipe testing chocolate chip cookies in Phnom Penh to perfect that American style cookie of soft and gooey on the inside, with crispy edges. This was a pretty happy time for those around me. Being around so many more internationals opened up a whole other world of baked goods, their expectations of them and their tastebuds. I enjoyed the challenge of trying to recreate those baked goods that they were nostalgically craving that I had never tasted before. And then of course selling them.

I learned stuff as I researched which I’ll share with you because that’s what this blog is about:

  • THE MOST IMPORTANT part is to REST the dough so that the baking magic can happen. Firstly, it allows the flour to absorb the fats and the liquids and thus create that puffy, crispy texture. Secondly, the sugars get a chance to chill out and mellow out resulting in richer flavour. In some baking chemistry magic by resting them, they will taste sweet but not overly sugary. It’s a minimum 2 hour wait if you’re impatient, but preferably overnight.
  • I often use a stand mixer to make this but the joy of this recipe is that as all the butter is melted, it is easy to do in a large bowl and a spatula/large mixing spoon.
  • Allow the brown butter to cool down. Sometimes I don’t and it results in a more delicate, tender cookie.
  • Remember with a cookie recipe, you don’t want to cream the butter and sugar together. We just want to mix them sufficiently, not beat air into them.
  • Mix up different types of chocolate to create a more complex chocolate profile, that’s why I use dark and milk chocolate. I read somewhere (I’m sure it was on Serious Eats but I can’t find the link) that if you use one type of chocolate then your taste buds get used to and stop tasting it. However, if you vary different makes or types of chocolate, your tastebuds will continue to taste them.
  • My recipe testing pales in comparison to Serious Eats. I am still learning.
  • Brown butter creates a rich, nutty flavour which I really enjoy.

Why do I call them crack cookies? That’s the nickname that my friend Grace gave them and it caught on. These cookies are really more-ish, sweetly addictive, soft but slightly crispy and satisfyingly not overly sweet. The brown butter gives a slightly nutty flavour, without any nuts, and the two types of chocolate means that each mouthful is a flavour party. I made two batches of these cookies for the soft opening of her store, Ginger and Grace. For some reason, they didn’t make it onto the tables but her friends discovered them later that evening and ate through an entire batch of them. I guess that cemented their reputation as crack cookies.

Now I tell people that these brown butter, chocolate chunk cookies are my best work.

The cookie recipe comes from Ambitious Kitchen. I haven’t made any major changes to it, except I like to weigh everything so obviously here I’ve converted it into grams. There’s a very similar recipe on Joy the Baker. The differences are that Monique browns ALL the butter, uses dark brown sugar, uses two different types of chocolate, adds in a tablespoon of greek yoghurt and doesn’t use nuts. Joy uses light brown sugar but adds in 1 tsp molasses, adds pecans and uses dark chocolate only. I prefer the Ambitious Kitchen version.

Ingredients for Brown Butter Chocolate Chunk Cookies very slightly adapted from Ambitious Kitchen

  • 227g butter
  • 100g white granulated sugar
  • 200g dark brown sugar
  • 1 large egg and 1 egg yolk
  • 1 tbsp natural yoghurt or greek yoghurt
  • 2 tsp vanilla extract
  • 280g plain flour
  • 1 tsp bicarbonate of soda
  • 1/2 tsp table salt
  • 140g dark chocolate cut into small chunks, or the chocolate chips, or round discs*
  • 140g milk chocolate cut into small chunks, or the chocolate chips, or round discs

*for prettier looking cookies: if using round discs of chocolate, keep around 21 discs aside to firmly place on the cookies after they have baked. The chocolate will temper as they melt and thus have a nice shine making them prettier to eat.

Method

  1. First brown the butter. Add all the butter to a medium-sized saucepan and place over medium heat. It will start to froth and cackle. That is the water evaporating. Continue and stir the sides and scrape the bottom a few times so that it doesn’t burn. When it is ‘as quiet as a ninja’ (quote from Stella Parks) it is ready. Take it off the heat and either pour the butter in a bowl to cool down, not forgetting to scrape the browned bits from the sides and bottom. Or as I often do, fill up the sink with cold water and carefully place the hot pan in there to cool down.
  2. Add both the sugars into a large mixing bowl and the cooled brown butter and mix for a minute or two until they are combined. I use the paddle beater (K-beater on the Kenwood). Don’t discard the egg white. Store it in the freezer for a cocktail or macaron/meringue baking on a later date.
  3. Now add in the vanilla extract, yoghurt and the large egg and egg yolk and mix again for a minute. It will look and smell like toffee.
  4. In a separate bowl, measure out the flour, bicarbonate of soda and salt and whisk to mix. Then add this to the butter/sugar/egg mixture and mix slowly so that the flour doesn’t fly up.
  5. When it looks like the flour has just about combined then add in the chocolate chunks and mix again.
  6. At this stage, I prefer to measure out into 2 tablespoons of cookie dough (I like to use a medium ice cream scoop) and roll them into balls and place them on a lined baking tray so that the cookie dough can chill out in the fridge for at least 2 hours before baking them. Sometimes, I will cover them and leave them overnight in the fridge to bake the following morning. More often, I will cover them and put them in the freezer overnight and then store the frozen cookie dough balls in a bag.
  7. When you’re ready to bake them, pre-heat the oven to 170°C/350°F/Gas mark 4 and line a baking sheet/tray with baking paper. Space them out so that there are 5 cms between each dough ball as they will spread. Sprinkle the cookies with a bit of table salt. If baking from chilled, bake for 11-13 minutes. If baking from frozen, bake for 14-16 minutes. The dough will spread out and go a golden brown colour. The middle will be gooey so when you take it out, it is important to leave them to cool and harden for 15 minutes on the baking sheet. Otherwise it will split into many pieces and chocolate goo will cover your fingers. That doesn’t sound too bad, does it. Haha.

You’re welcome and enjoy.

My favourite way of portioning out the cookie dough is with a medium sized icecream scoop.
In the absence of a scoop, weighing scales works. Preparing them for their overnight stay in the fridge hotel.

You can vary the flavour and texture. I added 140g dark chocolate and 140g chopped pecans to the cookies at the top of the post. You could substitute the pecans for walnuts or hazelnuts if you like. Play around with it and let me know how you get on.

Baking Tip: How to Make your own Buttermilk

I have a newest favourite ingredient. Buttermilk. Who would have imagined that buttermilk would hold that honoured position? Not only is it my current fad, but learning how to make my own buttermilk has felt liberating. I no longer feel like there’s a barrier stopping me from baking a recipe because buttermilk is ‘another ingredient that I don’t have’ or ‘where can I buy that from?’ when I come across it in a list of ingredients. Since discovering how to make my own cultured buttermilk, my oven has been turning out soda bread, raspberry and buttermilk cake and vast quantities of Allinson’s Banana Cake.

buttermilk and raspberry cake and banana cake

I first came across it when baking scones for an international tea party for 300 students. A friend of mine recommended Delia’s buttermilk scone recipe to me and every single batch turned out great. They rose perfectly and were springy in the middle. Then, I made the banana cake that was on the back of the self-raising flour packet with the leftover buttermilk. Wow – that turned out to be a winner too.

Buttermilk is the liquid that is leftover from the butter making process. Cultured buttermilk that is commonly sold in supermarkets today is curdled, sour milk. I know… I’m really selling it to you, aren’t I? Appetising, it does not sound. However, it is a lovely ingredient when you use it in baking because you’re pretty much guaranteed lightness and a good rise. When I researched the chemistry, I was told that the acid in the buttermilk reacts with the sodium bicarbonate to release carbon dioxide. Those large bubbles help the mixture to rise quickly. Oh, and means you can bake soda bread within an hour from start to finish.

There are two ways that you can make it:

1. Shake double cream really, really hard for a long time and not only will you have butter (and a new muscle-toning exercise) but you’ll have buttermilk from the leftover liquid, or

2. Add 1 tbsp/15ml of white or cider vinegar or lemon juice to 225ml/8fl oz of milk (preferably whole, or at least semi-skimmed) and wait about 10-15 minutes for it to curdle. This is the much easier way. Essentially, buttermilk is curdled, sour milk. I prefer to use lemon juice because the smell is that wee bit more safer when baking a sweet cake, but it doesn’t matter really.

I experimented, as you’d expect me to, with whether the fat content of the milk makes a difference. I think it does. Full-fat milk will curdle better. My results with skimmed milk were disappointingly watery. Those of you who are lactose intolerant or vegan will be pleased to read that you can make it with unsweetened soya milk too. It just needs a bit more vinegar/lemon juice.

I’m still chuckling to myself, as I write this, because it is a random ingredient to get excited about. Oh, I should also add that Miss Buttermilk comes as a pair with Mr. Bicarbonate of Soda.

Baking Tip: Substituting Vinegar for an Egg

Okay, so who knows about substituting vinegar for eggs in baking already?  I’m sure that this baking tip is one that many people are aware of.  However, I’d only heard of it 18 months ago and it’s taken me that long to be brave (or eggless!) enough to try it out.  So, I thought that I’d blog it to promote even more uses of vinegar.

A friend of mine told me that a tablespoon of vinegar can be a substitute for an egg in baking.  Admittedly I had quite a few questions and was a bit sceptical about it.  Such as, what kind of vinegar can I use – malt, white, red or any?  How does it work? And concerned about how a cake would taste with vinegar in it.  Anyway, when baking Nigella’s Clementine Cake recently, which asks for 6 large eggs and I only had 5, I decided to give it a go since the clementines had the potential to cover up the vinegar taste.  Quick google search (don’t I love it!) gave me enough details to give it a go. 

So, in answer to my questions.  I’d recommend using a tablespoon of white or cider vinegar with a teaspoon of bicarbonate of soda too as a substitute for an egg in a recipe.  Only use vinegar as an egg substitute when there’s a rising agent in the recipe, such as baking powder or self-raising flour. 

Perhaps someone knows more and could tell me more about the chemistry of how it works, please?

The only thing I gleaned is that when bicarb of soda and vinegar mix, it reacts to produce carbon dioxide, which is a gas and fizzes. Is that what makes it rise?  Here’s what it looks like when it mixes.

Did it affect the cake’s flavour?  Well, I used cider vinegar and could definitely smell it when I was mixing the cake.  However, perhaps it’s a bit like George’s marvellous medicine, because there was no hint of vinegar in the tasting of the cake! I brought some into work and noone could guess the secret ingredient!  Of course, it could have been because of the good old clementines dominating the flavour of the cake… But I’m definitely up for giving it another go.  When I was googling, I also found some rather cool chemistry experiments, an eggle
