Salted and unsalted butter can both be used to make cookies, but they do not give the baker the same level of control. Unsalted butter is usually preferred when following a precise recipe because the amount of salt can be measured separately. Salted butter can still make delicious cookies, but its salt level may vary between brands.
The difference is especially noticeable in butter cookies and shortbread, where butter is one of the main ingredients rather than a background flavour. When a recipe is simple, the quality, temperature and type of butter become much easier to taste.
Quick answer
Use unsalted butter when you want consistent results and full control over seasoning. If you only have salted butter, you can usually still use it, but reduce or omit the additional salt in the recipe.
What Is the Difference Between Salted and Unsalted Butter?
The basic difference is simple:
- Unsalted butter is made without added salt.
- Salted butter contains salt added during production.
The amount of salt in salted butter is not always the same. It can vary by brand, product and market. That variation is one reason professional bakers and recipe developers often begin with unsalted butter and add a measured amount of salt separately.
Using unsalted butter does not mean a cookie must taste bland. It simply gives the baker control over whether salt is added and, if so, exactly how much.
| Feature | Salted Butter | Unsalted Butter |
|---|---|---|
| Salt content | Contains added salt, with the amount varying between products | No added salt |
| Flavour | More noticeably seasoned or savoury | Clean dairy flavour with neutral seasoning |
| Recipe control | Less precise because the salt is already included | Allows salt to be measured separately |
| Best use | Toast, table use and recipes developed specifically for salted butter | Precise baking recipes, delicate flavours and butter-forward cookies |
Does Salted Butter Change the Taste of Cookies?
Yes, although the difference may be subtle.
Salt can make sweetness feel more balanced and can strengthen flavours such as chocolate, caramel, nuts and vanilla. In the right amount, it may make a cookie taste more complete rather than obviously salty.
However, if the butter already contains more salt than expected and the recipe also includes added salt, the finished cookies may taste overly seasoned. This matters most in delicate recipes where there are only a few ingredients and no strong flavour to cover the imbalance.
For a butter cookie, the goal is often to let the dairy aroma and gentle sweetness remain clear. Unsalted butter makes that balance easier to control.
Does Salted Butter Change Cookie Texture?
Not in one simple, predictable way.
It is tempting to say that salted butter always makes cookies softer, chewier or crispier, but cookie texture depends on many factors working together, including:
- The ratio of butter, flour and sugar
- The type of sugar used
- The amount of water in the butter
- The temperature of the butter and dough
- Whether the butter is creamed, melted or chilled
- The amount of gluten developed during mixing
- The baking temperature and baking time
The small amount of salt present in salted butter is normally not the main factor controlling whether a cookie is chewy, crisp or crumbly. Differences in butter composition between brands may contribute to small changes, but the recipe and baking method have a much greater effect.
For Lowrey Butter Cookies, the delicate melt-in-the-mouth texture comes from the complete balance of cultured butter, flour, corn starch, icing sugar and controlled baking. It is not created by choosing unsalted butter alone.

Does Salted Butter Make Cookies Spread More?
Salted butter does not automatically make cookies spread more.
Cookie spread is influenced more strongly by butter temperature, dough temperature, sugar, flour, baking tray temperature and the amount of water in the recipe. Warm or partially melted butter, for example, may cause dough to spread before the cookie structure has time to set.
Because different butter products can contain slightly different proportions of fat and water, changing brands may produce a small difference in spreading. That is a butter-composition issue rather than proof that salt itself causes cookies to spread.
Can You Substitute Salted Butter for Unsalted Butter in Cookies?
In most home cookie recipes, yes.
If a recipe calls for unsalted butter but salted butter is all you have, use the same weight of butter and reduce the added salt. As a practical starting point, reduce the recipe's salt by approximately ¼ teaspoon for every 113 g of salted butter.
This is only a guide because the salt concentration in salted butter varies. If the recipe contains very little salt, it may be simplest to omit the added salt entirely.
Example substitution
Suppose a cookie recipe calls for:
- 227 g unsalted butter
- ½ teaspoon salt
If you replace the unsalted butter with 227 g salted butter, you could begin by omitting the additional ½ teaspoon of salt.
The result should still be recognisably the same cookie, although the seasoning may differ slightly from the original recipe.
Can You Substitute Unsalted Butter for Salted Butter?
Yes. Use the same weight of unsalted butter and add salt separately if the recipe needs it.
If a recipe was developed using salted butter but does not state how much salt the butter contains, there is no perfect universal conversion. A small amount of salt can be added based on the quantity of butter and the desired flavour.
For consistent baking, it is better to record the butter brand and the amount of salt used once you find a result you like. Tiny details become annoyingly important in baking, because flour and fat apparently enjoy behaving like laboratory chemicals the moment a human wants a simple biscuit.
Which Butter Is Best for Butter Cookies?
Unsalted butter is usually the better starting point for butter cookies because it gives the baker more control and allows the natural dairy flavour to remain clear.
However, “salted or unsalted” is not the only question worth asking. The overall quality and character of the butter also matter.
When choosing butter for butter cookies, consider:
- Freshness: Butter readily carries dairy aromas, both good and bad.
- Butter flavour: A butter-forward cookie needs a clean, pleasant dairy taste.
- Fat and water balance: This can affect mixing, spreading and final texture.
- Consistency: Using the same type of butter helps produce repeatable results.
- Cultured or standard butter: These can produce different levels of flavour depth.
Which Butter Is Best for Shortbread?
Unsalted butter is also commonly preferred for shortbread.
Traditional shortbread relies on a very short ingredient list, usually built around butter, flour and sugar. With so few ingredients, the flavour of the butter is exposed. Unsalted butter lets the baker choose whether the shortbread needs salt and how much should be added.
Salted butter can still work, particularly when a slightly savoury contrast is wanted. The main precaution is to avoid adding the full amount of extra salt without considering what is already in the butter.
Is Cultured Butter the Same as Salted Butter?
No. These terms describe two different things.
- Salted or unsalted tells you whether salt has been added.
- Cultured or uncultured describes how the cream was treated before the butter was made.
Cultured butter is made from cream that has undergone a controlled culturing or fermentation stage. This develops a fuller dairy aroma and a more layered flavour.
Cultured butter can be either salted or unsalted. Likewise, standard sweet-cream butter can also be sold in salted and unsalted versions.
That distinction matters because removing salt does not automatically make butter cultured, premium or more flavourful. Unsalted simply means the butter contains no added salt.

Why Lowrey Uses New Zealand Cultured Butter
Butter is not a minor ingredient in a Lowrey Butter Cookie. It is central to the flavour, aroma and texture.
Lowrey Butter Cookies are made with approximately 42%–44% New Zealand cultured butter, depending on the flavour. In the Original Butter Cookies, the recipe is kept especially simple: cultured New Zealand butter, flour, corn starch and icing sugar.
There is no strong artificial flavouring in the Original recipe to disguise the butter. That means the quality and character of the butter have nowhere to hide.
We choose cultured butter because it brings:
- A fuller dairy aroma when the tin is opened
- More flavour depth than a flat, one-dimensional butter taste
- A rich but balanced finish that does not need excessive sweetness
- A butter-forward foundation for the cookie's delicate texture
The melt-in-the-mouth result does not come from butter alone. It comes from balancing cultured butter with flour, corn starch and icing sugar, then controlling how the dough is formed and baked.

Salted vs Unsalted Butter: The Final Answer
Both salted and unsalted butter can make good cookies. The better choice depends on the recipe and the result you want.
Choose unsalted butter when:
- You are following a precise baking recipe
- You want complete control over seasoning
- The cookie has a delicate or butter-forward flavour
- You want the most repeatable result between batches
Choose salted butter when:
- The recipe specifically calls for it
- You know the butter brand and like its level of salt
- You want a gentle savoury contrast
- You are prepared to reduce the additional salt in the recipe
For butter cookies, unsalted butter offers useful control, but the butter's quality, freshness, composition and flavour matter just as much. A cookie does not become exceptional merely because the word “unsalted” appears on the wrapper.
Frequently Asked Questions
Can I use salted butter if a cookie recipe calls for unsalted butter?
Yes. Use the same weight of salted butter and reduce or omit the salt listed separately in the recipe. Because salted butter varies between brands, the final seasoning may be slightly different.
Should I always use unsalted butter for baking?
Not always, but unsalted butter is often preferred because it allows the baker to measure salt separately. If a recipe was developed using salted butter, follow the recipe as written.
Will salted butter ruin cookies?
No. Salted butter will not automatically ruin cookies. The most common risk is simply that the finished cookies may taste saltier than intended if the recipe's additional salt is not reduced.
Does salted butter make cookies chewy?
Not by itself. Chewiness is influenced more strongly by the type and quantity of sugar, flour, eggs, moisture, mixing method and baking time.
Does unsalted butter make cookies crispier?
Not automatically. Crispness depends on the full recipe and baking process. Unsalted butter mainly gives the baker better control over salt rather than guaranteeing a particular texture.
Is salted butter better for chocolate chip cookies?
Some people enjoy the contrast of salt with chocolate, but unsalted butter still provides more control. You can use unsalted butter and add a measured amount of salt to achieve the same sweet-savoury balance more consistently.
Is cultured butter always unsalted?
No. Cultured butter may be salted or unsalted. “Cultured” describes the treatment of the cream, while “salted” describes whether salt was added.
What butter does Lowrey use?
Lowrey Butter Cookies are made with New Zealand cultured butter. Butter content is approximately 42%–44%, depending on the flavour. The Original Butter Cookies use a simple four-ingredient recipe of cultured New Zealand butter, flour, corn starch and icing sugar.
