Everyone has their own preferences on how their cookie should be. Chewy or crispy? Living in New Zealand, one of our national treasures is the beloved Cookie Time cookie, and I’ve grown up microwaving such palm-sized creations for the perfect melted cookie.
I have also grown up knocking my teeth on Griffins chocolate chippie cookies. The kind where you clamp the cookie between your molars and angle it to snap off a bite.
Whatever your idea of a perfect cookie is, understanding the science can help you develop your go-to recipe.
Crispy cookies
Crispy cookies are actually easier to make. Soft cookies have a water concentration of 6% or higher – moisture being the variable in texture. To make cookies crispy, add less liquid or bake it in the oven for longer to dry out the dough.
Generally bake around 13-15min at 180C for a crispy cookie. But if you want a thoroughly crispy cookie – not those just charred on the outside – decrease the temperature to 140C and bake for 30min.
Chewy cookies
Sugar dissolved in baking forms a syrup as the dough heats up. Different types of sugars affect the texture because they absorb different amounts of water. 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. When butter is melted, it coats the flour more evenly, resulting in cookies that are chewier and denser. This can be desirable for certain types of cookies, like chocolate chip cookies or brownie-like cookies.
Extra tip
Chilling your cookie dough before baking prevents the cookie from spreading and creating cookie disasters like below. If you don’t have time or the self-control to wait overnight, pop them in the freezer.

Mochi cookies
These were a game-changer for me! It’s combining two of my loves – and all you need to make the mochi is a microwave. You can make them filled or unfilled depending on your tastes and preferences. You can create any flavour of mochi using freeze dried fruit powder.
This mochi cookie recipe is my OG. And if you’re a lover of biscoff, you can take it to the next level with the biscoff mochi cookies.
Beyond the chocolate chip cookie
If you’re looking for something beyond the classic chocolate chip, I loved developed the ube cookie. Thanks to the addition of ube halaya (ube jam) in the recipe, these cookies are perfectly fudgy and stay moist for days. In fact, the flavour develops and deepens, tasting even better after Day 1!
Even more wild is the potato chip cookie. Potato chips, dark chocolate and cookie seems like an unlikely trio, but if you lovebothsweet and savoury snacks – this is THE recipe for you. It’s like a platter party in your mouth.

What makes cookies crispy or chewy? ›
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.
How should a baker adjust their formula to achieve a crisp cookie texture versus a soft cookie texture? ›
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 can cause a cookie to be too chewy or not chewing enough? ›
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 causes cookies to be chewy? ›
Eggs bind the ingredients and make for moist, chewy cookies. Adding too many eggs can result in gummy, cake-like cookies. Adding too few eggs can result in dry, crumbly cookies.

As Levy Beranbaum writes in The Baking Bible, replacing a little bit of the flour in the dough with cornstarch results in “a more delicate cookie that is also easier to pipe or push through a cookie press.” Adding cornstarch helps tenderize tough gluten, contributing to a softer cookie dough with a finer crumb after ...
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.
What makes cookies flat and crispy? ›
Melted butter – To achieve thin and crisp cookies, I've discovered that melted butter is really crucial. Melted butter helps the cookies to spread out and become flatter with crisp edges.
You could also re-crisp them by baking on a wire rack in a 300 degree F oven for a few minutes.
What is the science of baking cookies? ›
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.
How do I make sure my cookies are chewy? ›
Two ways that you can help make sure your chocolate chip cookies come out soft and chewy is to add a packet of cook-and-serve vanilla pudding mix to the batter, or add finely shredded chocolate instead of chunkier chocolate. The smaller chocolate particles will melt faster and create more moisture in your cookies.

Why are my cookies so crispy? ›
The temperature of your oven plays a huge role in the texture of your cookies! A lower oven temperature will give your cookies more time to spread before they start to rise, resulting in a crispier cookie. I recommend baking your cookies for a bit longer at a lower temperature to achieve the texture you're looking for.
How do you increase crispness in cookies? ›
Using more white sugar in your cookies will result in a crispier end product. To achieve a crispy cookie, skip the rest in the fridge. Baking your cookies right after making the dough will encourage them to spread in the oven, resulting in an extra-crispy cookie.
