If you need to substitute butter for 1/3 cup of oil, you’ll generally need approximately 5 and 1/3 tablespoons of butter. Some sources suggest a slightly different ratio, like using 4 parts of butter for every 3 parts of oil.
Ever been in the middle of mixing up some yummy cookies or a fluffy cake and oops! You realize you’re all out of butter, but you’ve got a bottle of oil sitting right there?
We’ve all been there! Suddenly, that simple question pops into your head: “Okay, so how much of this oil do I need to use instead of that 1/3 cup of butter the recipe calls for?”
It seems like it should be a simple swap, right? Like trading one apple for another? But when it comes to baking, butter and oil aren’t exactly the same.
They have different weights and how much fat they contain, which can change how your baked goods turn out.
Don’t worry! This isn’t some baking mystery we can’t solve. In this little guide, we’re going to figure out roughly how much oil you can use when a recipe asks for 1/3 cup of butter.
We’ll also chat about some important things to keep in mind when you’re making this switch. Plus, we’ll touch on how the type of recipe can make a difference. So, let’s get baking smarter, not harder.

Can You Substitute Oil for Butter? (Briefly address the reverse)
Just like you can swap butter for oil, you can also go the other way around and use oil when a recipe calls for butter. However, just like before, you’ll want to keep those same important things in mind: texture and flavor.
For example, if a recipe relies on the solid fat of butter to create a certain structure (like in some cookies that spread less), using oil might result in a flatter and potentially more chewy outcome. And of course, you’ll miss out on that distinct buttery taste.
When it comes to the amounts, some baking guides suggest that you might want to use slightly less oil than the amount of butter the recipe calls for. This is often because oil is 100% fat, while butter has water and milk solids.
So, using a little less oil can help prevent your baked goods from feeling too greasy. Again, it often comes down to the specific recipe and the kind of result you’re hoping for.
The Straight Answer: How Much Butter for 1/3 Cup Oil?
So, let’s get right to the heart of it! If your recipe calls for 1/3 cup of oil and you want to use butter instead, you’ll need approximately 5 and 1/3 tablespoons of butter.
Keep in mind that this is a general estimate based on how much space each takes up (their volume). To really compare them accurately as liquids, you’d need to melt the butter first.
Why It’s Not a Simple 1:1 Swap: Understanding the Differences
You might be thinking, “Why can’t I just use the same amount of butter as the oil the recipe asks for?”
That’s a totally fair question! The thing is, butter and oil are a bit different under the surface, and these differences can affect your baking. Let’s take a closer peek:
Density Matters
Imagine filling two identical glasses, one with butter and the other with oil, up to the same line. Even though they look like they take up the same amount of space, the glass of butter would actually weigh more than the glass of oil.
This is because butter is denser – it packs more stuff into the same amount of space.
What’s Inside Counts
Think about what butter is made of. It’s not just pure fat; it also contains water and tiny bits of milk solids. Oil, on the other hand, is usually 100% fat.
These extra ingredients in butter change how it acts in your baking compared to oil.
Solid or Liquid?
Butter is interesting because it can be a solid at room temperature and a liquid when you heat it up.
This solid versus liquid state can make measuring a little tricky if you’re trying to swap it directly for oil, which is almost always a liquid.
For a fair comparison based on volume, you’d really need to melt the butter first.
What to consider When Substituting Butter for Oil?
So, you’re thinking about swapping butter for oil (or maybe the other way around)? That’s cool! But before you go ahead, there are a few important things to keep in mind that can really change how your final dish turns out.
Let’s explore some of these key considerations:
How it Feels (Texture)
Butter has a special way of making things tender. Because of its fat structure and the water inside, it can sometimes lead to a slightly denser but still lovely texture.
Oil, on the flip side, often makes baked goods super moist and gives them a soft crumb. Think about the difference between a chewy cookie made with butter and a really moist muffin made with oil.
That Yummy Taste (Flavor)
Let’s be honest, butter has that classic, rich flavor that’s hard to miss! Oil, especially neutral oils like vegetable or canola oil, doesn’t really add much flavor.
If you use a flavored oil, like olive oil, it will definitely change the taste of your recipe – which could be delicious, but something to think about!
Getting Things to Rise (Leavening)
When you beat butter and sugar together (that’s called creaming), you’re actually trapping tiny air bubbles. These little bubbles help your cakes and cookies rise and become light and fluffy.
Oil can’t do this the same way because it’s a liquid. So, if a recipe relies heavily on creaming butter for its lift, using oil might result in something a bit flatter.
How Wet It Is (Moisture Content)
Remember how we said butter has water in it? This means it adds some liquid to your recipe. Oil is pure fat, so it doesn’t add any extra water.
Some smart bakers even suggest that if you’re using oil instead of 1/3 cup of butter, you might want to reduce the other liquids in the recipe by about a tablespoon to balance things out.
This can help make sure your baked goods aren’t too wet.
It Depends on What You’re Making (Recipe Type)
Whether your substitution works well really depends on what you’re baking or cooking. For example, swapping oil for butter in a batch of brownies might work great and give you a fudgy result.
But trying to do the same in a delicate butter-based cake could change the texture quite a bit. Savory dishes might be more forgiving when it comes to this kind of swap.
Butter to Oil Ratio in Different Scenarios (Expand if needed based on top articles)
You might find that some baking experts suggest a slightly different approach than a straight volume-for-volume swap, like our earlier estimate.
For instance, some sources mention using a ratio of about 3 parts oil for every 4 parts of butter. This is because of those differences in density and fat content we chatted about.
When it comes to specific baked goods like cakes or cookies, the top articles often highlight that the texture you’re aiming for really matters.
Cakes
If a cake recipe relies heavily on the structure created by creaming butter, simply swapping in the same amount of oil might make the cake less fluffy.
Some bakers suggest using slightly less oil than the butter called for, maybe closer to that 3:4 ratio, to avoid a cake that’s too dense or oily.
Cookies
For cookies, the results can vary a lot! Using oil can often lead to a chewier cookie. If you’re going for a crispier cookie that usually comes from butter, you might need to play around with the amount of oil, possibly using a bit less.
It’s worth noting that while there are general guidelines, baking can be a bit of an experiment! Sometimes, the best way to figure out the perfect substitution for a specific recipe is to do a little research on that type of bake or even try a small batch first.
Conclusion
So, when you’re in a pinch and need to swap butter for 1/3 cup of oil, remember that around 5 and 1/3 tablespoons of melted butter are a good starting point.
But don’t forget that the type of recipe really matters! Think about what the fat does in your bake and be ready for some possible changes in how it feels and tastes.
