How Much Is 2/3 Of A Stick Of Butter

We’ve all been there. You’re mid-recipe, the butter is rock-hard from the fridge, and the instructions casually demand “2/3 of a stick.” Your brain freezes. Is that a full stick minus a sliver? A whole stick plus a little bit? You stare at the wrapper like it owes you money.

Let’s clear this up before you huck the entire stick into the batter out of frustration. A standard stick of butter in the US is 8 tablespoons or ½ cup. So, ⅔ of a stick is a little over 5 tablespoons. Specifically, it’s 5 tablespoons plus 1 teaspoon. Yes, it’s that specific.

Think of it this way: if a stick of butter were a sausage, you’d need to cut off a chunk that’s roughly the length of your thumb. Or, if you’re a visual person, it’s the amount you’d use to generously butter a loaf of banana bread—but not quite enough to make it look like you’re hosting a butter sculpture contest.

Why Recipes Do This To Us

Recipes love fractions. It’s like they’re playing a cruel game of “guess the exact amount.” They could say “5 tablespoons,” but instead, they go with ⅔ of a stick. Why? Because measuring sticks is faster for bakers who do this in their sleep. For the rest of us, it’s a math pop quiz we didn’t sign up for.

The real tragedy is that most sticks have measuring marks on the wrapper. You know, those little lines that are supposed to help. But half the time, the marks are for tablespoons, not fractions. So you end up squinting at the paper, trying to decide if “⅔” is between the “4 T” and “8 T” marks. Spoiler: it is, but it’s a guestimate.

The Hack That Saves Dinner

Here’s the trick that changed my baking life: use a knife to cut the stick lengthwise. No, that’s not right. Actually, just cut the stick in half horizontally. A whole stick is 8 tablespoons. So, half a stick is 4 tablespoons. You need 5 and a third tablespoons. So, take one whole stick (8 T), cut off a quarter of it (about 2 T), and you’re left with 6 T. That’s too much. Okay, forget that.

The real hack: grab a second stick. Cut 1 whole stick (8 T) and then cut ⅓ off the second stick. That gives you 8 T + 2.66 T = 10.66 T. See? Still confusing. The simplest move is to mark your butter knife. Or just buy a kitchen scale. Weigh it: 1 stick = 113 grams. So ⅔ of a stick = about 75 grams. Easy peasy, metric squeezy.

What This Looks Like In Real Life

Imagine you’re at a dinner party. Someone asks for “just a pat of butter.” You hand them ⅔ of a stick. They’d look at you like you just served them a butter brick. But in baking, that amount is the goldilocks zone for cookies that spread perfectly without turning into greasy puddles.

I once made cookies using a full stick instead of ⅔. The result? They tasted delicious, but they also looked like pancakes that gave up on life. Flat, sad, and wide. The butter was the culprit. Too much fat makes cookies spread like gossip at a family reunion.

Conversely, using just half a stick (which is ½, not ⅔) gives you a dough that’s so stiff you could use it to patch a tire. The cookies come out like hockey pucks. So, ⅔ is that sweet spot. It’s the butter of moderation—not too much, not too little, just enough to make your kitchen smell like heaven.

A Tale Of Two Butters

One time, I was making shortbread. The recipe said “⅔ of a stick, softened.” I was in a rush, so I microwaved the butter for 10 seconds. It exploded. Not a full explosion, but a butter volcano that coated the inside of my microwave. I ended up scraping out what looked like ⅔ of a stick, but it was really just melted butter with some butter bits floating in it.

The shortbread turned out… okay. It was greasy and crumbly, like a biscuit that cried itself to sleep. The lesson? Softened means room temperature, not lava. Take the butter out early, let it sit, and then cut your ⅔ piece like a civilized person.

Or, just use the wrapper lines. Most American butter sticks have tablespoon marks. Look for the line that says “5 ⅓ T” if you’re lucky. If not, just cut the stick into three equal parts—two of those parts are your ⅔. Is it exact? No. Is it close enough for a Tuesday night batch of cookies? Absolutely.

Let’s Be Honest

In the end, ⅔ of a stick of butter is about 5 tablespoons and a smidge. It’s the amount you’d use to make a decent roux, a perfect pie crust, or a batch of brownies that won’t make your friends judge you silently. If you’re off by a teaspoon, the world won’t end. Probably.

So next time you see “⅔ of a stick” in a recipe, don’t panic. Take a deep breath. Picture a stick of butter. Cut off a little more than half. If you end up with ¾ of a stick, just call it a “generous ⅔” and move on. The butter police aren’t coming.

And if they do? Offer them a cookie. They won’t know the difference.
