What Makes Some Cookies Chewy and Some Crisp? | undefined (2024)

ATK Kids

Kids can explore the answer with a sweet science experiment that’ll leave you with a mixed batch of sugar cookies.

Published Dec. 17, 2021.

The ingredients you use and how you shape your cookies both play an important role in whether your cookies turn out crispy or chewy. The type of flour and sugar you use, if your cookie dough contains eggs, and whether you use melted or softened butter all factor into the crispy-chewy equation, too.

To explore one side of the crispy-chewy conundrum, we created an edible science experiment for kids in The Complete Cookbook for Young Scientists (you can also find it on our kid-friendly website). Kids bake one batch of cookies with white granulated sugar, and one batch of cookies with dark brown sugar. Naturally, there’s a taste test to help them determine the results.

As kids eat and examine the cookies, they’ll notice that the cookies made with brown sugar are darker in color; have a moister, chewier texture; and bend easily. Their cookies made with white sugar will be lighter in color; have a drier, crispier texture; and will snap when bent. That’s partly due to brown sugar (which is just granulated white sugar with molasses added to it) adding more water to the cookies than white sugar thanks to that molasses.

Another reason cookies made with brown sugar are moister and chewier? Sugar is hygroscopic—it’s really good at absorbing and holding on to water from its surroundings. And brown sugar is even more hygroscopic than white sugar.

Bottom line: When it comes to cookies, the type of sugar you use matters.

FAQs

What Makes Some Cookies Chewy and Some Crisp? | undefined? ›

Remember moisture is the key! White sugar creates crispier cookies and brown sugar creates chewier cookies. Why use melted butter? Melted butter creates cookies with a different texture compared to cookies made with softened or creamed butter.

What makes a cookie chewy and crispy? ›

The ingredients you use and how you shape your cookies both play an important role in whether your cookies turn out crispy or chewy. The type of flour and sugar you use, if your cookie dough contains eggs, and whether you use melted or softened butter all factor into the crispy-chewy equation, too.

What is the secret to chewy cookies? ›

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.

Why did my cookies come out chewy? ›

Brown sugar—particularly dark brown sugar—makes a cookie chewy; white sugar makes it crispy. If your recipe calls for all white sugar and you want a fudgier result, try swapping out some of the white sugar for brown (go for half and half and adjust from there).

What contributes to a chewy cookie? ›

Cookies that are dense and chewy incorporate more moisture into the batter. This can be achieved by making substitutions with wet and dry ingredients, or even just changing the way you incorporate certain ingredients. Plus, your particular baking technique and your method of storing cookies can also play a role.

How do you keep cookies crisp and chewy? ›

Room temperature: Use airtight containers, cookie jars, or plastic bags to prevent air exposure and moisture loss. Keep cookies in a cool, dry area. Refrigerated: Use airtight containers or sealed plastic bags to store cookies in the fridge. Monitor the moisture level to avoid condensation.

How do you increase crispness in cookies? ›

Using lower-moisture sugar (granulated) and fat (vegetable shortening), plus a longer, slower bake than normal, produces light, crunchy cookies. That said, using a combination of butter and vegetable shortening (as in the original recipe), or even using all butter, will make an acceptably crunchy chocolate chip cookie.

What are three factors that cause a cookie to be crisp? ›

Final answer: The crispness of a cookie is influenced by the ingredients, their proportions, and the baking conditions.

What happens to cookies with too much egg? ›

If there isn't enough egg, your batter or dough may not be able to hold its structure or could end up overly dry or dense. On the other hand, if there is too much egg, your baked goods could lose their shape due to excess liquid, or have a rubbery (or even overly cakey) texture depending on the recipe.

Why did my cookies come out crispy? ›

Adding too little flour can cause cookies to be flat, greasy, and crispy. Most recipes assume you'll use all-purpose, but if you want a lighter, crumblier cookie texture, choose one with a lower protein content such as cake-and-pastry flour. Baking soda helps cookies spread outward and upward while cooking.

What flour is best for chewy cookies? ›

Bread Flour: For Chewy Texture

Bread flour contains a higher protein content (around 12-14%), leading to more gluten development. This makes it ideal for bakers seeking a chewier texture in their cookies. The extra gluten can help retain gas and moisture, producing a denser and chewier result.

What ingredient contributes most to a crisp cookie? ›

Fat is a very important ingredient in cookies – it tenderizes, crisps and browns, adds color and a wonderful flavor that is impossible to duplicate. Butter, our fat of choice, ensures good baking results and adds the most desirable taste, texture and appearance.

What is the secret to making good cookies? ›

The key is to always use top-quality ingredients as they'll result in a better cookie; it really is that simple.
  1. Always use butter.
  2. Choose the right sugar.
  3. Choose the right flour.
  4. Check your flour is in date.
  5. Choose the right kind of chocolate.
  6. Cream the butter and sugar.
  7. Beat in the eggs.
  8. Fold in the flour.

What causes a cookie to be too crispy? ›

Adding too little flour can cause cookies to be flat, greasy, and crispy.

How do you make cookies chewy after baking? ›

The best way to soften up those hard cookies is something you probably already have in your kitchen… bread! That's right, a piece of fresh bread will make those tough treats soft and chewy.

What makes cookies soft instead of crunchy? ›

Soft-baked cookies are often made using a solid fat with a higher melting point, which prevents the cookie from spreading while baking. The result is a thicker, softer, chewier cookie. Another simple trick for softer cookies is to use chilled dough.

Does melting butter make cookies chewy? ›

By switching up the technique, I omitted all the extra air that gets incorporated into the dough during creaming, and as a result, the cookies made with melted butter were significantly chewier and fudgier than those made with creamed butter.
