You're standing in the kitchen, flour on your jeans, looking at a recipe that demands precision while your brain is doing backflips. Maybe the measuring cup is in the dishwasher. Or maybe you're trying to scale down a massive batch of brown butter blondies and suddenly the math isn't mathing. It happens. Honestly, figuring out how many teaspoons in 2/3 cup of butter sounds like a simple fifth-grade math problem until you're actually staring at a cold stick of Land O'Lakes trying to divide it into tiny segments without a ruler.
Let's just get the "quick and dirty" number out of the way first. There are 32 teaspoons in 2/3 cup of butter.
That's the raw data. But if you’re actually baking, knowing the number 32 is only half the battle. Butter isn't a liquid you just pour into a spoon—well, unless you’ve melted it, which changes the volume dynamics anyway. Most of us are dealing with sticks, tablespoons, and the weird geometry of American dairy packaging.
Why 2/3 Cup of Butter is a Kitchen Nightmare
Standard American butter sticks are a weirdly specific unit of measurement. One stick is 1/2 cup. So, when a recipe calls for 2/3 cup, you're looking at one full stick plus a chunk of a second one. This is where people usually mess up their cookies. If you just eyeball it, you're either going to end up with a dry, crumbly mess or a puddle of grease that spreads across the baking sheet like an oil slick.
To get to 2/3 cup, you need 10 tablespoons plus 2 teaspoons.
Think about that for a second. Most people just try to guess where "two-thirds" of a stick is, but because a stick is already a fraction of a cup, your internal compass is probably off. If you’re using the "wrapper method"—you know, those little lines printed on the paper—you have to be careful. Those lines are almost always slightly skewed. If the paper slipped during the packaging process at the factory, your "tablespoon" might actually be a tablespoon and a half.
Breaking Down the Math (The Boring but Necessary Part)
Mathematics in the kitchen is about ratios. We know that 1 cup equals 48 teaspoons. This is a hard rule. So, when we do the math for a partial cup, we take 48 and multiply it by 0.666.
$$48 \times \frac{2}{3} = 32$$
It's a clean integer. That's rare in baking math. Usually, you end up with some horrific repeating decimal that requires a pipette to measure out. But 32 is a solid, workable number.
If you're more comfortable with tablespoons—which, let's be real, most of us are—the math gets a little funkier. There are 3 teaspoons in a single tablespoon. Since we have 32 teaspoons total, you divide that by 3. You get 10 tablespoons with 2 teaspoons left over.

The Conversion Hierarchy
Sometimes it helps to see the "family tree" of these measurements.
- 1 Cup = 48 Teaspoons
- 3/4 Cup = 36 Teaspoons
- 2/3 Cup = 32 Teaspoons
- 1/2 Cup = 24 Teaspoons (or one standard stick)
- 1/3 Cup = 16 Teaspoons
If you're trying to measure this out using a standard 1-teaspoon measuring tool, you're going to be there for a while. It’s tedious. You’ll probably lose count around teaspoon sixteen and have to start all over again. Don't do that to yourself.
The Density Problem: Weight vs. Volume
Here is something professional pastry chefs like Claire Saffitz or the folks over at King Arthur Baking will tell you: stop using spoons.
Seriously.
Butter is a fat. It’s susceptible to temperature. If your butter is "room temperature," it might have expanded slightly. If it’s rock hard from the fridge, you might leave gaps in your measuring cup, which means you’re actually getting less butter than the recipe wants. This is why how many teaspoons in 2/3 cup of butter is actually a bit of a trick question in high-end baking.
Volume is a liar. Weight is the truth.
A single cup of butter weighs approximately 227 grams. If we take our 2/3 ratio, we find that you need exactly 151.3 grams of butter. If you have a digital kitchen scale, just put a bowl on it, tare it to zero, and slice off chunks of butter until the screen says 151 grams. It’s faster. It’s cleaner. You don't have to wash 32 teaspoons afterward.
What Happens if You Get it Wrong?
Baking is chemistry. Unlike cooking a stew where you can "sorta" add more salt or "kinda" throw in extra garlic, baking relies on the interaction between fats, sugars, and leavening agents.
If you use 30 teaspoons instead of 32, your cake might be slightly more structural, but it will lack that "melt-in-your-mouth" quality. If you accidentally go over and use, say, 36 teaspoons (which is 3/4 cup), your cookies will spread too much. They’ll be thin, greasy, and probably burn at the edges before the center is even cooked.

Butter provides more than just flavor; it provides air. When you cream butter and sugar together, the sugar crystals actually carve tiny little tunnels into the fat. These tunnels hold air. When the heat of the oven hits the dough, that air expands, and the water in the butter turns to steam. This is what makes a cake fluffy. If you mess up the measurement of how many teaspoons in 2/3 cup of butter, you're messing with the entire aeration process of your bake.
The Metric Confusion
If you're reading a recipe from the UK or Australia, things get even messier. In the US, a "cup" is technically 240 milliliters (mostly). In other parts of the world, a metric cup is 250 milliliters.
While a 10ml difference doesn't sound like much, it scales. If you're doing 2/3 of a cup, that gap can actually change the texture of a delicate souffle or a batch of French macarons. Always check where your recipe author is from. If they’re using grams, stay in grams. If they’re using teaspoons, make sure you’re using a standard US teaspoon which holds exactly 4.93 milliliters of liquid.
Practical Ways to Measure 2/3 Cup Without Losing Your Mind
If you don't have a scale and you refuse to count out 32 teaspoons, you have a few options.
First, the displacement method. Take a liquid measuring cup and fill it to the 1-cup mark with cold water. Add chunks of butter until the water level rises to 1 and 2/3 cups. Because the butter has displaced exactly 2/3 cup of water, you know you have the right amount. Just pat the butter dry with a paper towel before you use it so you don't mess up the hydration of your dough.
Second, use the stick markings but do the math.
One stick is 8 tablespoons.
You need 10 tablespoons plus 2 teaspoons.
So, you use one full stick, then take a second stick and cut it at the "2 tablespoon" mark. Add those 2 tablespoons to the first stick. Then, you still need 2 more teaspoons. Since a tablespoon is 3 teaspoons, you just cut off two-thirds of one tablespoon from the second stick.
It sounds like a riddle, but it works.
Common Misconceptions About Butter Volume
One thing people often ask is whether melted butter takes up more space than solid butter. The answer is: not significantly, but the way you measure it changes.
When you melt butter, the air trapped in the solid fat escapes. If a recipe says "2/3 cup butter, melted," you should measure the 32 teaspoons of solid butter first and then melt it. If the recipe says "2/3 cup of melted butter," it means you should melt a bunch of butter and then measure out the liquid. It's a subtle distinction that has ruined many a Thanksgiving pie crust.

Also, salted vs. unsalted butter doesn't change the volume. 32 teaspoons of salted butter is the same amount of fat and water as 32 teaspoons of unsalted. However, the salt content can affect how the gluten in your flour develops, so stick to what the recipe asks for.
Real-World Example: The "Big Cookie" Mistake
A few years ago, a popular food blog posted a recipe for giant Levain-style cookies. The recipe called for 2/3 cup of cold, cubed butter. A lot of commenters complained that their cookies turned into flat pancakes.
The culprit? They were measuring "cubed" butter in a measuring cup.
When you cube butter, you create air gaps between the cubes. If you fill a 2/3 measuring cup with cubes, you're actually only getting about 24-26 teaspoons of actual butter because of all that empty space. This is exactly why knowing that you need 32 teaspoons in 2/3 cup of butter is so vital. If you had counted the teaspoons or weighed it out to 151 grams, the cookies would have stayed thick and puffy.

The "Stick" Hack
If you’re using European-style butter, like Kerrygold, it often comes in a larger 8-ounce block rather than 4-ounce sticks. These blocks usually don't have the same handy tablespoon markings. In this case, don't even try to use teaspoons. Cut the block in half—that’s 1 cup. Then, visually divide that half into three equal sections. Take two of those sections. You now have roughly 2/3 cup. Again, it’s not as precise as a scale, but if you’re just making pancakes or a simple crumble, it’ll get the job done.
Actionable Tips for Better Baking
To ensure your measurements are never the reason for a baking fail, adopt these habits immediately. First, buy a cheap digital kitchen scale; it’s the only way to be 100% sure about your butter volume. Second, if you must use spoons, use a straight edge (like the back of a butter knife) to level off the top of the spoon. Don't "heap" the butter unless the recipe specifically tells you to.
Finally, keep your butter cool while measuring unless the recipe calls for it to be softened. Warm butter is squishy and sticks to the sides of measuring tools, meaning you leave behind a teaspoon or two of fat that was supposed to be in your dough. Every teaspoon counts when you're aiming for that perfect 32.
To get the most accurate results, always measure your butter while it is firm. Slice the butter into small, even pieces before measuring it into teaspoons to ensure there are no air pockets. If you are using a measuring cup, press the butter down firmly with a spatula to eliminate any gaps. Once you have reached the 2/3 cup mark or counted out your 32 teaspoons, allow the butter to reach the temperature specified in your recipe—whether that's room temperature for creaming or chilled for flaky pastry. This sequence preserves the volume while ensuring the proper texture for your bake.
