Melted, Cold, Room-Temperature: Here’s How Butter Temperature Affects Cookies (1)

In a never-ending quest to find the most perfect chocolate chip cookies of all time — seriously, we’ve ranked both high-effort and classic recipes — we learned that one of the most magical factors in cookie flavor and texture is also one of the most common baking ingredients: butter. While most recipes call for bringing butter to room temperature for creaming, some standout cookies call for melted or even cold butter to cut down on prep time or improve the texture of the finished cookies.

So let’s geek out for a bit on our favorite cookie ingredient and learn what melted, cold, and room-temperature butters do in our favorite cookie recipes.

What Does Butter Do in Cookies?

While butter is primarily fat that gives flavor, tenderness, and flaky layers to baked goods, it also has a bit of liquid (some water, some milk bits) that also contribute to structure and rise. For example, in a classic chocolate chip cookie, creaming together the butter and sugar incorporates air into the cookie dough. That air works with the baking soda or powder to puff or rise the cookie along with the steam created within the cookie thanks to the butter and egg’s moisture.

Butter also plays a critical role in cookie structure; the fat and moisture can enhance or inhibit gluten development, which directly impacts the shape, spread, and texture in your cookies. In short, the temperature of your butter for cookies directly impacts how cakey, crispy, or flaky your cookies will be.

What Does Softened Butter Do in Cookies?

Most cookie recipes call for beating room-temperature butter. At a temperature between 70 and 72 degrees F, butter is soft enough to incorporate air, but not so soft that it will melt immediately in the oven and result in super-thin cookies. This semi-soft form of butter also helps the fat coat proteins in the cookie dough, preventing gluten development — making a cookie that has a finer texture and is more cake-like than chewy.

What Does Melted Butter Do in Cookies?

Tara O’Brady’s Great Basic Chocolate Chip Cookie is a delicious example of a chewy cookie that is near perfect in texture, thanks to melted butter. O’Brady is specific that the butter be melted slowly, over low heat to prevent any evaporation. In its liquid state, butter mixes readily with both the sugar and flour, making for a softer dough that actually develops more gluten (thanks to the butter’s moisture hydrating the flour). If the just-mixed dough is baked straight away, cookies made with melted butter spread more than those made with room-temperature butter — good news for lovers of thin-and-crispy cookies. On the other hand, if you scoop cookie dough made with melted butter into rounds and then chill the dough before baking, you’ll end up with a cookie that is soft, chewy, and crispy only on the edges.

What Does Cold Butter Do in Cookies?

There is a case to be made for making some cookies with cold butter. When incorporated in its harder, from-the-fridge state, butter makes baked goods flaky by creating layers in the dough and cutting through gluten development. Pie crust and croissants are prime examples of butter’s cold, hard form being used to make a better texture. Sarah Copeland’s Thousand Layer Cookies are a good example of manipulating butter while cold: The dough is made with room-temperature butter but then chilled to harden the butter, then the dough is rolled and folded to create a flaky layered chocolate chip cookie. This cold butter technique makes for a super-crispy cookie with a tender center.

FAQs

Melted, Cold, Room-Temperature: Here’s How Butter Temperature Affects Cookies? ›

Most cookie recipes call for beating room-temperature butter. At a temperature between 70 and 72 degrees F, butter is soft enough to incorporate air, but not so soft that it will melt immediately in the oven and result in super-thin cookies.

Is melted or room temp butter better for cookies? ›

“Room temp butter is able to hold onto air,” Szewczyk says. “You can mechanically shove air into it by creaming. Warm butter is not able to hold onto it, so you're going to get a denser dough.” When using warmer or melted butter, cookies will struggle to lift and lighten, resulting in a cakier texture, like brownies.

What happens if you use cold butter instead of room temperature? ›

If the butter isn't at room temperature, it won't blend smoothly with the sugar and you'll end up with a bunch of butter shards with crystallized sugar instead of a nice creamy whip. In other words, not softening your butter may result in your cookies going splat instead of puffing up.

Does melted butter cause flat cookies? ›

Butter that is completely melted or warm to the touch won't incorporate enough air into the dough, leading to an improper rise.

What happens to cookies if you use melted butter instead of softened butter? ›

Cookies made with melted butter often deflate and become denser when they cool, resulting in a perfectly cooked fudgy center — a similar textural result to brownies that get rapped (aka banged against an oven rack mid-bake to deflate them) or Sarah Kieffer's iconic pan-banging cookies that turn out pleasantly compact.

Does more butter make cookies softer? ›

Also, underbaking them by a minute or 2 will help them retain a dense, chewy bite, explains Jenny McCoy, pastry baking arts chef-instructor at the Institute for Culinary Education in New York. Adding more moisture to your dough in the form of extra butter, egg yolks, or brown sugar will make your cookies even softer.

What is the best temperature to bake cookies? ›

Cookie temperatures fluctuate, with some recipes as low as 300 degrees Fahrenheit, and a few as high as 425 degrees Fahrenheit, but most recipes land on 375 or 350 to evenly bake the entirety of the cookie.

Why did my cookies come out flat? ›

The Problem: Your Oven Is Too Hot

If your cookies repeatedly turn out flat, no matter the recipe, chances are your oven is too hot.

What to do if you melted butter instead of softened? ›

If the recipe calls for softened butter and you accidentally melted butter instead of softening it, it's best that you set aside the melted butter for future use. Both kinds of butter will yield a very different final result in every baked good.

Should melted butter be cooled before baking? ›

For best results when using melted butter, let it cool to room temperature before incorporating.

Does it matter if butter is melted or softened? ›

In the case of pie dough, cold butter steams in the oven, creating the air pockets that make for flaky layers; melted butter, on the other hand, creates a tender, more shortbread-like crust—buttery and delicious all the same, but firmer and more compact.

How long can melted butter sit out? ›

But, if you're in the heat of baking and forget to put the last little knob back in the fridge right away, that's ok—just so long as you don't let it sit out for a few extra hours. “Do not leave butter at room temperature for more than 4 hours,” says Engen.

Should butter be melted or room temperature for cookies? ›

Most cookie recipes call for beating room-temperature butter. At a temperature between 70 and 72 degrees F, butter is soft enough to incorporate air, but not so soft that it will melt immediately in the oven and result in super-thin cookies.

What makes cookies fluffy and not flat? ›

Flour adds fluff and texture to the cookies. 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.

Why are tollhouse cookies flat? ›

Flat cookies can be the result of a number of issues. Here are some of the main possibilities: OVEN TEMPERATURE: Be sure to have your oven pre-heated and ready to bake. Also be sure that the thermometer is reading correctly.

Does melting butter make a difference? ›

And, sometimes, melted butter actually produces a more desirable texture. If, for example, the idea of a cakey or fluffy cookie makes you cringe, seek out recipes that call for melted butter, which produces denser, lower-profile results.

What happens if you use melted butter instead of softened for bread? ›

The results of the three methods were pretty much the same. They all worked well and there were no issues. So, the conclusion would be that it is ok to add butter right at the beginning of the mix; and it could be softened, cold, or melted.

Should butter be cold or room temp for sugar cookies? ›

To prevent flat sugar cookies that spread into little puddles, it's important to make sure your butter is at a COOL room temperature. Your sticks of butter should give slightly when pressed with your finger but still hold their shape. To be precise, your butter should be 67°F.

Can I melt butter instead of creaming it? ›

The microwave will melt your butter rather than soften it, and that affects how the cake will turn out! Remember - you can't cream sugar with melted butter! Creaming butter and sugar together until it's light and fluffy is a basic step in a lot of baking recipes, and it's essential for a good bake!
