Here’s the deal: There are 1.5 servings of 2/3 cup in one full cup. That’s one and a half. So if you’re using a 1/3 cup scoop, you need two of those to make 2/3, and then one more to get that extra half. Yes, it’s basically a math problem that involves your measuring cups and a little patience.
Think of it like this: If a cup were a pizza, 2/3 of that pizza is a solid slice-and-a-half. You’d need one whole 2/3 slice, then half of another one to finish the pie. That’s why we have scales and eyeballs, people.
Why this feels like a life hack—and a trap
I once tried to make a double batch of brownies and needed 1 and 1/3 cups of flour. I stood there with a 2/3 cup measure, convinced I could do this in my sleep. I filled it once, then again, and then realized I only had two-thirds of what I needed. Panic. I dumped it back, recalculated, and eventually just used a 1/3 cup three times. My brownies were fine. My ego? Not so much.
The real trick is to remember: One full cup equals three 1/3 cups. So two 1/3 cups make 2/3. To get one full cup from 2/3, you need half of another 2/3. That’s why the answer is 1.5. It’s like asking how many half-hours are in an hour—two, obviously—but with fractions, your brain freezes.
