Two. Two 1/3 cups make exactly 2/3 cup. That’s it. You can stop reading now if you’re in a rush and your cookies are about to burn.
But if you want to feel a little smarter and maybe laugh at how our brains overcomplicate things, stick around. We’ve all been there, holding a 1/3 cup and a 2/3 cup, feeling like we’re solving a riddle from an ancient scroll.
Let’s compare it to real life
Think of a 1/3 cup as one slice of your favorite pizza. The whole pizza—the full cup—is three slices. So two slices? That’s exactly 2/3 of the pizza. You’d never hesitate to grab two slices; why hesitate with measuring cups?
It’s the same logic as splitting a candy bar with a friend. If the bar has three sections, and you give yourself two, you’ve taken 2/3. No calculator needed, just pure, delicious arithmetic.
