The Science of Cookies (2024)

FAQs

What is the science behind cookies? ›

They rise. As the butter melts, the cookie's structure loosens, so that the water in the dough is able to combine with the baking soda, dissolving it. The baking soda then reacts to the acidic components present in brown sugar, creating gases that cause the cookie to rise.

Cornstarch helps product soft and thick cookies. Using more brown sugar than white sugar results in a moister, softer cookie. An extra egg yolk increases chewiness. Rolling the cookie dough balls to be tall and lumpy instead of wide and smooth gives the cookies a bakery-style textured thickness.

The final reaction to take place inside your cookie is caramelization and it occurs at 356º F. Caramelization is what happens when sugar molecules break down under high heat, forming the sweet, nutty and slightly bitter flavor compounds that define… caramel!

If you enjoy your cookies soft and chewy, chances are likely the recipe contains a common ingredient that serves a very specific purpose. No, it's not granulated sugar, nor the butter. It's not the egg, all-purpose flour, or even the vanilla extract. The simple, yet oh-so-necessary component is cornstarch.

The first physical reaction occurs at 92 degrees Fahrenheit. That is the temperature at which the butter starts to melt. The melted butter spreads the cookie out into its flatter shape. At this point, all the ingredients are still the same and there is no change in taste.

Corn Syrup (Light)

Light corn syrup is something you can add to any cookie mix to help achieve softness. This isn't the type of corn syrup regularly sold in various stores, but more of a sugar that verges on liquid, helping the other sugars in the mix to remain more liquid-like when baked.

Softened butter and melted butter are not the same. Using melted butter will change the texture of whatever you're baking. If you only want the butter to soften for spreading, microwave it on the Defrost setting (30%) in 5-second increments until it's softened as desired.

Room temperature butter is just the right consistency to incorporate air when it's creamed with sugar. These trapped air pockets result in risen, fluffy cookies. If the butter is any warmer, it won't incorporate enough air and your cookies will have less rise.

The job of butter in baking (besides being delicious) is to give richness, tenderness and structure to cookies, cakes, pies and pastries. We alter the way butter works in a recipe by changing its temperature and choosing when to combine it with the other ingredients.

Why are my cookies brown? ›

Not Enough Flour

If your cookies are flat, brown, crispy, and possibly even a bit lacy around the edges, that means you need to add flour to your dough for the next batch.

1. Cookies. Cornstarch does kind of incredible things to cookies. I mean not only does it give them soft centers, prevents them from spreading, and makes them somewhat thick (in a good way), but it also contributes to the chewiness factor, which, in my opinion, is the most important cookie attribute.

Cookies become hard when the moisture in them evaporates. This can be caused by leaving them out in the air for too long, baking them for too long, or storing them improperly. The lack of moisture makes the cookies hard and dry, which makes them difficult to enjoy.

So, when you mix corn syrup into your cookie batter, all of that moisture will make and keep your baked cookies deliciously tender. The texture of cookies benefits from corn syrup as well. As you combine your ingredients to make your cookie batter, corn syrup will pull some of the surrounding air into your batter.

Several promoters of cookie diets say their protein content helps to curb hunger, and two -- Smart for Life and Dr. Siegal's -- chalk this up, at least partly, to the particular amino acids they contain. A number of studies imply that this claim could be true.

Chemistry, as you mix different edible chemicals to create dough or batter, with tiny air bubbles trapped inside. Biology, as the culture of yeast provides carbon dioxide to make your bread rise. And physics, as those trapped gases expand and give the rise to the bakes.

But now it's time to learn the science behind why you crave a glass of milk when you eat something sweet. For one thing, milk helps blunt sweetness by coating your tongue, so it acts almost like a palate cleanser that clears the way for another bite of that chewy snickerdoodle or coconut macaroon.
