The main reason why I love cookies is because it is what made me fell in love with baking. Cookies were the first thing I ever baked, probably because they looked pretty simple to bake. However after baking them a couple of times I figured out things weren’t really as simple as they appear to be. All cookies are baked using 4 basic ingredients – flour, butter, sugar and eggs, everything else is added for flavor and texture. But baking them is not easy as it sounds, especially when you are looking for certain textures.
The most popular cookie in America has to be the Chocolate Chip Cookies and from my understanding everyone here loves a soft and chewy chocolate chip cookie. At first I did not understand the craze because I come from a country where cookies = crispiness. We never ate soft cookies and hence had no idea. In fact this year when I was in India for vacation I baked a batch of soft cookies and someone asked me, so these are not done right? you are going to bake them more and make it all crispy? I really didn’t know what to say, nobody understands a soft cookie in India!
But now I love crispy and soft cookies equally. Crispy for dipping in my tea and soft and chewy cookies as treats. It’s amazing how different baking time, sugar, flour, egg, everything has an effect on the final cookie texture. Well that’s why baking is so exciting 🙂 Let’s talk a bit about cookie science in making these soft and chewy chocolate chunk cookies.
What makes a cookie chewy and soft is the high moisture content in the cookie dough. I don’t think one ingredient can make a cookie soft and chewy, it is the interaction of a number of ingredients which gives a perfect texture to your cookies. Using brown sugar, extra egg yolk, cornstarch and oil all contribute to a soft cookie. How? Let’s see.
# Brown sugar is hygroscopic which means it absorbs moisture from air and ensures that cookies stay soft & chewy. So I used a higher ratio of brown sugar to white sugar in this recipe.
# Egg yolk helps to add moistness whereas egg whites dry out the cookies, so when you add an extra egg yolk you increase the moistness leading to a softer and denser cookie.
# One of the main ingredients for soft and puff cookies is cornstarch. It acts as a tenderizing ingredient and helps prevent gluten development.
# We all know that fat plays an important role in how your cookie will spread. I like using cold, room temperature butter for my cookies and also add 2 tablespoons of canola oil to it. Oil really kept these cookies soft for a longer time. What is cold, room temperature butter? If you press butter with your finger you should be able to make an impression/dent but it should still be firm to touch.
# Now we come to chilling the dough. If you are at a place where it’s really warm, it is a good idea to chill the dough for at least 2 hour or even overnight. Cookie dough which is chilled before baking holds it shapes and results in puffier cookies. I did not chill my dough because a) I had no time, I made these for an event at the last minute b) it was quite cold the day I made these so I thought they would hold well even without chilling.
If you are looking for thick puffy cookies, make sure that the dough is piled high on the baking sheet. Like you can place 1 tablespoon of dough on the baking sheet and then place another tablespoon of dough over it. Also do not bake them for a longer time if you want soft cookies, bake them anywhere between 9-11 minutes and take them out while center is still puffy. Let them cool down on the baking sheet for 10 minutes before transferring them on to a wire rack to cool completely. I baked mine for 11 minutes.
I was able to get 24 cookies out of this dough, you might get more or less depending on how much dough you use per cookie.
* You can add more or less of chocolate chunk depending on taste and preference.
* Bake longer and skip the cornstarch for crispier cookies.

Hi thanks for sharing. These look great but how are the measurements in metric system?
this is an old recipe hence it doesn’t have measurements in grams, sorry. I will need to work on this recipe again and then update it. For reference I use 1 standard US cup which is 8 oz (240 ml).
Can we use any substitute to egg. Since we don’t eat eggs?
use flax egg or chia egg!
cookies are so tempting and perfect dear!
These look so good. I would have to eat half a dozen of these!
