I Don't Have A 2/3 Cup What Can I Use

Welcome to the wonderful, slightly chaotic world of improvised baking! You’re in the middle of a recipe, the butter is softening, the eggs are cracked, and then you see it: 2/3 cup. You check your measuring cup set. You have a 1/3 cup, a 1/2 cup, a 1 cup—but no 2/3 cup. Panic? Never! This is actually a fun little puzzle that turns you into a kitchen problem-solver. The purpose of this article is simple: to show you that a missing measuring cup is not a disaster, but an opportunity to get creative. The advantage? You’ll never let a missing cup stop you again, saving time, money, and frustration—plus, you’ll feel like a math wizard (without the scary equations).

Let’s start with the easiest trick in the book: grab your measuring spoons. You might not have a 2/3 cup, but you almost certainly have a tablespoon. Here’s the magic: 2/3 cup equals exactly 10 tablespoons plus 2 teaspoons. Why does this work? Because 1 cup is 16 tablespoons, so 2/3 of that is about 10.67 tablespoons—which breaks down neatly. Just scoop ten level tablespoons, then add two level teaspoons. It takes a few extra seconds, but it’s foolproof. If you’re feeling fancy, you can even memorize this: 10 tbsp + 2 tsp = your missing 2/3 cup. This method is perfect for sticky ingredients like honey or oil, because spoons are easier to scrape clean than a big cup.

Now, let’s get geometric with your existing measuring cups. You’ve got a 1/3 cup handy, right? That’s your golden ticket. Since 2/3 cup is simply two times 1/3 cup, fill your 1/3 cup twice and dump it into the bowl. Simple. But what if you only have a 1/2 cup and a 1/4 cup? No problem—think of it like a recipe puzzle. Fill the 1/2 cup, then subtract by adding a 1/4 cup? No, that’s too mathy. Instead, do this: fill the 1/2 cup once, then fill the 1/3 cup halfway (eyeball it). That’s close enough for most batters. Or, use the 1/4 cup twice (that’s 1/2 cup), then add two tablespoons (since 2 tablespoons = 1/8 cup). The key is to trust your eye—baking is science, but a little wiggle room won’t ruin cookies. For precision, use the 1/3 cup twice; for speed, combine 1/2 cup + 2 tablespoons.

Don’t forget the power of liquid measuring cups. If you have a clear glass or plastic measuring cup with markings (the kind with a spout), you’re golden. Simply pour water, milk, or oil until it reaches the 2/3 cup line on the side. But wait—what if your cup only has markings for 1/4, 1/2, and 1 cup, and no 2/3? Look closer. Many cups have tiny lines between the big marks. The line halfway between 1/2 cup and 3/4 cup is exactly 2/3 cup (since 2/3 is 0.666, and 3/4 is 0.75). If your cup doesn’t have that, use the 1/2 cup mark plus a little more to the 3/4 line—or just use water displacement: fill a 1-cup measure with 1/3 cup of water, then fill the rest with your ingredient until it reaches the 1-cup line. That’s 2/3 of your ingredient! (Just drain the water first if you’re using dry stuff, but for liquids it works perfectly as a measuring hack.)

What about when you’re working with dry ingredients like flour or sugar? This is where the scoop-and-sweep method shines. Grab a 1/2 cup and a 1/4 cup. Fill the 1/2 cup, then add one tablespoon plus one teaspoon from the 1/4 cup. But here’s a pro tip: since 1/4 cup equals 4 tablespoons, using 1/2 cup + 2 tablespoons (which is 1/8 of a cup) gets you to 5/8 cup—just a smidge under 2/3. To fix that, add 2 more teaspoons (since 2 teaspoons = about 1/10 of a cup). Honestly, for flour, if you just fill a 1/2 cup and a 1/4 cup and level them both, you’ll end up with very close to 2/3—about 0.75 cups total, which is slightly more. But in cookies or pancakes, a few extra tablespoons of flour won’t ruin them. If you need absolute accuracy for a cake, stick to the 10-tablespoon-plus-2-teaspoons method. It’s the most reliable.

Now for a creative, no-measurement hack: use a common household object. A standard coffee mug is about 8 ounces, which is 1 cup. So eyeball two-thirds of that mug’s height. Or use a yogurt container—those 6-ounce cups are 3/4 cup, so fill it to the upper line? No, 2/3 cup is 5.33 ounces, so fill a 6-ounce cup to about 88% full. But that’s too fussy. Here’s the real hack: if you have a 1-cup measure, fill it with water to the 2/3 mark, then pour that water into your dry ingredient’s bowl to see the volume. Then dump the water and use that visual cue to scoop flour until it matches. This is called the water displacement method for the lazy, and it works because your brain is great at comparing volumes. For liquid ingredients, just use the water as your guide—pour it out, then pour your oil or milk to the same level in the same cup. Instant 2/3 cup without any measuring spoons!

Finally, here’s some practical advice for when you try these hacks. First, always use dry measuring cups for dry ingredients and liquid cups for liquids—mixing them can throw off your ratios because of meniscus issues. Second, level your measurements with a flat edge, like a knife, for accuracy. Third, if you’re scaling a recipe up or down, remember that 2/3 cup is the same as 0.66 cups on a digital scale—you can weigh your ingredient (for example, 150 grams of sugar for 2/3 cup). This is especially handy for brown sugar, which is compacted. Fourth, don’t stress: most recipes are forgiving. A 1/2 cup plus a 1/4 cup (3/4 cup total) might make your cakes slightly denser, but they’ll still taste great. The best advice? Practice these tricks now, before your next baking crisis. Try making a batch of cookies using only the tablespoon method, then another using the 1/3 cup double-fill. See which feels faster. Soon, you’ll have the confidence to improvise with joy—and your friends will think you’re a kitchen magician. So next time you don’t have a 2/3 cup, smile, grab whatever you do have, and get mixing. You’ve got this.
