Baking is where fractions get serious. If you’re making cookies and you double a recipe that calls for 2/3 cup of brown sugar, you need exactly 1 and 1/3 cups. Too much sugar and your cookies spread like a lazy cat. Too little, and they’re sad little pebbles. No one wants pebbles.
Here’s a pro tip: When measuring brown sugar, pack it down like you’re trying to hide a secret. Scoop it into your measuring cup and press it firmly with the back of a spoon. Level it off with a knife. This ensures you get the full 2/3 cup, not a fluffy, airy lie.
For liquids like milk or oil, use a clear glass measuring cup. Pour to the 1 and 1/3 line. Easy peasy, lemon squeezy. But don’t lift the cup to eye level—that’s how you spill. Bend down like a polite person and check the meniscus. (That’s the curved bottom of the liquid. See? You’re learning science.)

What about scaling up even more?
Say you’re feeding an army. 2/3 cup times 3 is 2 cups (since 6/3 simplifies to 2). Times 4? That’s 8/3, or 2 and 2/3 cups. You’re becoming a multiplication machine. Virginity of math shame, be gone!
I remember the first time I tried to double a soup recipe. I confidently added “2/3 cup times 2” of tomato paste, but I misread the measuring cup and added 1 and 1/2 cups. The soup turned into lava. Don’t be like me. Trust the math, not your hungry eyeballs.
Here’s a funny truth: Most measuring cups are liars. That 2/3 cup mark is often squished between the 1/2 and 3/4 marks, and it’s easy to overfill. Use a separate 1/3 cup measure if you have one. It’s like using a dedicated spoon for peanut butter—just less sticky.
If you’re really in a bind, you can use a kitchen scale. Weighing is the most accurate method. 2/3 cup of all-purpose flour weighs about 85 grams. So, 1 and 1/3 cups is about 170 grams. No fractions, no tears.
Let’s pause and appreciate fractions for a second. They’re not trying to ruin your day. They’re just tiny, weird-shaped numbers that live in cookbooks. They have their own little society. 2/3 is like the cool, rebellious fraction that refuses to be a neat half or a simple quarter. We respect its hustle.
