How Many Teaspoons In 2/3 Cup Of Butter? | No Guesswork

Two-thirds cup of butter equals 32 teaspoons, which is also 10 tablespoons plus 2 teaspoons.

Butter math can trip people up fast when a recipe shifts from cups to spoons. One card says 2/3 cup. Your spoon set says teaspoons and tablespoons. Your butter wrapper may show stick marks. Now you’re standing there doing mental math with cold butter in one hand and a mixing bowl in the other.

The good news is that this conversion is clean and easy once you break it down. In U.S. kitchen measures, 1 cup equals 16 tablespoons, and 1 tablespoon equals 3 teaspoons. That gives you a simple path from cups to tablespoons to teaspoons, with no guessing and no messy half-cuts that throw off a bake.

If you only need the direct answer, 2/3 cup of butter is 32 teaspoons. If you want the version that’s easier to measure in a real kitchen, it’s 10 tablespoons plus 2 teaspoons. That form is often handier when you’re cutting from a block, using measuring spoons, or working with butter that isn’t sold in stick form.

Why This Butter Conversion Matters In Real Cooking

Butter does more than add richness. It shapes texture, browning, spread, and moisture. In cookies, a small change can shift the dough from thick and chewy to thin and greasy. In frostings and sauces, too much or too little can throw the whole balance off.

That’s why a clean conversion matters. A rough guess with butter is rarely harmless. A teaspoon here or there may sound tiny, yet a few missed spoonfuls stack up fast when you’re working with a fraction like 2/3 cup. If you’re doubling, halving, or swapping between cups and spoons, accuracy saves the batch.

This also comes up when recipes come from different places. One version may list butter in sticks. Another may use tablespoons. A nutrition tracker may use grams. If you know how 2/3 cup breaks down, it becomes much easier to move between those formats without stopping every few minutes.

How Many Teaspoons In 2/3 Cup Of Butter? With The Full Breakdown

Here’s the exact kitchen math:

• 1 cup butter = 16 tablespoons
• 2/3 cup butter = 16 × 2/3 = 10 2/3 tablespoons
• 1 tablespoon = 3 teaspoons
• 10 2/3 tablespoons = 32 teaspoons

So the full answer is 32 teaspoons. If you don’t want to measure out 32 separate spoonfuls, just use 10 tablespoons plus 2 teaspoons. That gives you the same amount with much less fuss.

There’s another way to see it. Since 1/3 cup equals 5 tablespoons plus 1 teaspoon, doubling that gives you 10 tablespoons plus 2 teaspoons. Same answer. Same total. Just a cleaner path for many home cooks.

What That Looks Like In Butter Sticks

In the U.S., 1 stick of butter equals 1/2 cup, which is 8 tablespoons. That means 2/3 cup equals 1 stick plus 2 tablespoons plus 2 teaspoons. If your butter wrapper has tablespoon marks, you can cut 1 full stick, then add 2 more tablespoons and 2 teaspoons from a second stick or block.

If your butter is sold in tubs, blocks, or imported packs without U.S. stick markings, measuring by spoon or by weight is easier. That’s one reason many bakers like a scale. According to the NIST kitchen measurement chart, 1 teaspoon is 5 mL, 1 tablespoon is 15 mL, and 1 cup is 240 mL. That makes 2/3 cup about 160 mL in kitchen rounding.

Salted And Unsalted Butter Use The Same Volume

Salted butter and unsalted butter use the same spoon and cup conversion. The salt changes flavor, not the basic volume measure. So 2/3 cup of either type is still 32 teaspoons.

What may change is the taste of the finished dish. In baking, unsalted butter gives you tighter control over seasoning. In savory cooking, salted butter may work just fine. The volume math stays the same either way.

Best Ways To Measure 2/3 Cup Of Butter

You’ve got a few solid options, and the best one depends on the butter you have in front of you.

Using Stick Marks

This is the easiest route when your butter comes in U.S. sticks with tablespoon lines on the wrapper. Cut 1 full stick, then count out 2 more tablespoons. After that, take 2 teaspoons from the next tablespoon. You’ll hit 2/3 cup without dirtying extra measuring cups.

Using Measuring Spoons

If the butter is soft, scoop 10 level tablespoons and then add 2 level teaspoons. Try not to pack air gaps into the spoon. Level the top with a straight edge if the recipe needs accuracy, like shortbread, pie dough, or buttercream.

Using A Measuring Cup

If the butter is very soft, you can press it into a dry measuring cup until it reaches the 2/3 cup line. This works, though it can get messy and is less tidy than spoon or weight methods.

Using Weight

Many bakers trust weight most because it removes the question of how firmly the butter was packed. King Arthur Baking lists 1/2 cup butter as 113 grams in its ingredient weight chart. That puts 2/3 cup at about 151 grams. In practice, most cooks round that to 151 or 152 grams.

If your recipe is in grams, use the gram figure and skip the spoon math. That’s often the cleanest move when you’re scaling a recipe up or down.

Butter Amount	Tablespoons	Teaspoons
1/8 cup	2 tbsp	6 tsp
1/4 cup	4 tbsp	12 tsp
1/3 cup	5 tbsp + 1 tsp	16 tsp
1/2 cup	8 tbsp	24 tsp
2/3 cup	10 tbsp + 2 tsp	32 tsp
3/4 cup	12 tbsp	36 tsp
1 cup	16 tbsp	48 tsp

Common Mistakes When Measuring Butter

Most butter mistakes are small on their own, yet they pile up. The first one is mixing liquid cup logic with dry scoop logic. Butter sits in a strange middle zone. It’s solid when cold, soft when room-temp, and melted when warm. That changes how it fills a spoon or cup.

Another slip is treating “2/3 cup” like “a bit more than half a cup” and eyeballing it. That can work in a pan sauce. It usually falls apart in baking. Butter-heavy recipes have less room for loose measuring.

Some people also forget that 2/3 cup is not 10 tablespoons flat. It’s 10 tablespoons plus 2 teaspoons. Those extra 2 teaspoons matter. Leave them out and you’re short by one-sixth of a stick. That’s enough to change the spread of cookies or the crumb of a cake.

Cold Butter Vs Soft Butter

Cold butter is easier to cut cleanly from marked sticks. Soft butter is easier to scoop into spoons. Melted butter is easiest to measure by volume in a liquid cup, though you should only melt it if the recipe allows it. Melted and softened butter do not behave the same way in batter or dough.

If the recipe says softened butter, don’t melt it just to make measuring easier. Measure first, then soften. That keeps the structure of the recipe where it should be.

Butter Conversion By Weight, Spoons, And Sticks

When you cook often, it helps to see 2/3 cup in a few kitchen languages at once. That way, you can move between recipe styles without stopping to recalculate.

• 2/3 cup butter = 10 tablespoons + 2 teaspoons
• 2/3 cup butter = 32 teaspoons
• 2/3 cup butter = 1 stick + 2 tablespoons + 2 teaspoons
• 2/3 cup butter = about 151 to 152 grams
• 2/3 cup butter = about 5.3 ounces by weight

That weight line is handy when you buy butter in 250-gram packs, which is common outside the U.S. Instead of carving out odd spoonfuls, you can just cut close to 151 grams and move on.

Format	2/3 Cup Butter Equals	Kitchen Note
Teaspoons	32 tsp	Good for spoon-only measuring
Tablespoons	10 tbsp + 2 tsp	Less scooping than 32 teaspoons
Sticks	1 stick + 2 tbsp + 2 tsp	Works with marked U.S. butter sticks
Grams	151 to 152 g	Best for scale baking
Ounces	About 5.3 oz	Handy with package labels

How To Scale This Conversion Up Or Down

Once you know the base math, scaling gets much easier. If you need half of 2/3 cup of butter, divide 32 teaspoons by 2. That gives you 16 teaspoons, which is 1/3 cup. If you need double, multiply 32 by 2. That gives you 64 teaspoons, which is 1 1/3 cups.

This comes up all the time in smaller bakes. A full recipe may call for 2/3 cup, yet you only want a half batch. Or a frosting recipe may need one and a half times the original butter. Working from teaspoons or tablespoons gives you a cleaner route than trying to eyeball cup fractions.

Handy Mini Math

• Half of 2/3 cup butter = 16 teaspoons
• One and a half times 2/3 cup butter = 48 teaspoons
• Double 2/3 cup butter = 64 teaspoons

If you scale often, writing these beside a recipe card saves time on repeat bakes. It also cuts down on those little mistakes that show up when you’re tired, rushed, or halfway through a long ingredient list.

When Teaspoons Are Better Than Cups

Measuring butter in teaspoons sounds fussy at first. Still, it can be the better move in small-batch baking, pan sauces, compound butters, and recipes that need just part of a stick beyond the wrapper marks.

Say you already used most of a stick and only have scraps left in the dish. Spoon measures let you finish the recipe without trying to rebuild a neat cup measure out of uneven chunks. Teaspoons also help when you’re converting a large recipe into a tiny test batch.

That said, if you have a digital scale, weight is still the cleanest path for repeatable results. Spoons are fine. Scales are calmer.

Final Answer For The Kitchen Counter

If you need the plain answer to tape on the fridge, here it is: 2/3 cup of butter equals 32 teaspoons. The easier kitchen version is 10 tablespoons plus 2 teaspoons. If you’re using sticks, that’s 1 stick plus 2 tablespoons plus 2 teaspoons. If you’re using a scale, it’s about 151 to 152 grams.

Once you know that one conversion, a lot of butter math starts to feel less annoying. You can shift between cups, spoons, sticks, and grams without second-guessing the recipe, and that makes the whole bake smoother from the first mix to the last crumb.
