Here’s the part where I sound like a late-night infomercial. You can buy a 2/3 cup measuring cup for about three bucks. But where’s the fun in that? This is a challenge. It’s you versus the recipe. You win by using your wits and a 1/2 cup. Plus, your kitchen drawers are already too full of that one weird spatula you never use. Don’t add more to the pile.
Final life hack: if you’re making something forgiving—like chili, soup, or a brownie mix from a box—just go ahead and use a generous 1/2 cup. The difference is less than 2 tablespoons. Will anyone notice? Probably not, unless you’re baking a soufflé for a French judge. In that case, see the spoon strategy above. Otherwise, relax. You’re not a robot. And even if you mess up, you’ve learned the most important lesson of all: 2/3 cup is just 1/2 cup plus a cheerful lie about the rest.
Now go bake something. And stop panicking.
