Butter isn’t just fat and flavor — the amount of water and milk solids in it, and whether it’s salted or not, changes how a copycat recipe browns, rises, and holds together. Grabbing whatever stick is in the fridge usually works, but knowing the differences matters more in baking than almost anywhere else in the kitchen.
The Main Types of Butter
Salted Butter
Standard butter with salt added, mostly as a preservative originally, now mostly for flavor. Fine for spreading, cooking, and most savory applications, but the salt content varies noticeably by brand (typically 1.5–2.5% by weight), which makes it harder to control seasoning precisely in baking.
Unsalted Butter
Butter with no added salt, which is why most baking recipes (including nearly everything on this site) call for it specifically — it lets you control salt separately and precisely. Unsalted butter also tends to be fresher on average, since salt’s preservative effect means salted butter can sit longer before it’s packaged.
European-Style Butter
Churned longer than standard American butter, resulting in a higher butterfat content (typically 82–86% versus about 80% for standard U.S. butter) and less water. The extra fat and lower water content make a real difference in laminated doughs (croissants, danish) and in cookies, where less water means less gluten development and a more tender result.
Clarified Butter / Ghee
Butter with the water and milk solids removed, leaving pure butterfat. Because the milk solids (which burn easily) are gone, clarified butter and ghee have a much higher smoke point, making them useful for high-heat searing where regular butter would scorch. Ghee goes a step further than clarified butter, cooking the milk solids briefly before straining, which gives it a nuttier flavor.
Why Salted vs. Unsalted Actually Matters in Baking
The issue isn’t flavor — it’s control. Salted butter’s salt content varies by brand and isn’t listed precisely on most packaging, so a recipe written and tested with unsalted butter plus a measured amount of salt gives a consistent, repeatable result. Swap in salted butter without adjusting, and you’re adding an unknown, uncontrolled amount of extra salt on top of what the recipe already calls for. For a single batch of cookies it rarely ruins anything, but in bread doughs (where salt also controls yeast activity) and in delicate glazes and frostings, it can throw off both flavor balance and texture.
Why Butter Temperature Changes the Result
- Cold butter (pie dough, biscuits, scones): stays in small solid pieces through mixing, then melts in the oven, releasing steam that creates flaky layers.
- Room-temperature (softened) butter (most cookies and cakes): creams properly with sugar, trapping air bubbles that help the batter rise and give a lighter crumb.
- Melted butter (some cookies, quick breads): produces a denser, chewier texture since no air gets creamed in — this is why some copycat cookie recipes deliberately melt the butter for a chewier bite.
- Browned butter: butter cooked until the milk solids toast and turn golden-brown, adding a nutty, caramel-like depth that plain melted butter doesn’t have — a common upgrade in cookie and frosting recipes.
Substituting Between Butter Types
- Salted → unsalted: use the same amount and add roughly ¼ teaspoon of salt per stick (½ cup) to match typical salted-butter salt content
- Unsalted → salted: use the same amount and reduce any added salt in the recipe by about ¼ teaspoon per stick
- Standard → European-style: use the same amount by volume; expect a slightly richer result, most noticeable in laminated doughs and shortbread
- Butter → ghee/clarified (for high-heat cooking only): use the same amount; do not substitute in baking recipes that rely on butter’s water content for steam and structure
Buying Guide
Unsalted butter is the right default for nearly every recipe on this site — it lets each recipe’s own salt measurement do the work. Keep salted butter around separately for spreading on bread or finishing a dish at the table. European-style butter is worth the upgrade specifically for laminated pastry, pie crust, and shortbread, where the higher fat content is most noticeable; for everyday cookies and cakes, standard unsalted butter is not a meaningful downgrade.

Frequently Asked Questions
Why do baking recipes almost always call for unsalted butter?
Salt content in salted butter varies by brand and isn’t precisely listed, so unsalted butter plus a separately measured amount of salt gives a consistent, repeatable result every time.
Can I substitute margarine for butter?
You can, but expect a different texture and flavor — margarine has a different fat and water composition than butter, which changes how it creams, browns, and behaves in laminated or flaky doughs.
Why does my recipe say to use cold butter cut into cubes?
For pie dough, biscuits, and scones, small solid pieces of cold butter melt during baking and release steam, which is what creates flaky, distinct layers. If the butter is soft or melted going in, that layering effect is lost.
