So, what is 2/3 + 2/3 cups? It’s 1 and 1/3 cups. That’s it. No rounding, no algebra, no tears. Think of it like this: if you have two slices of a cake that’s cut into three pieces, and someone gives you two more pieces, you don’t have a full cake. You have one whole cake plus one extra slice.
Basically, you’ve crossed the finish line of “enough” and landed in “a little extra.” And in baking, a little extra is usually a good thing. Unless you’re measuring salt. Then maybe put the spoon down.
Why Your Brain Freezes (And Why It’s Okay)
The moment you see “2/3” in a recipe, your brain does a little panic dance. It’s not a clean number like a half cup or a full cup. It’s that awkward middle child of measurements. We’ve all been there, squinting at the markings on the side of a Pyrex, trying to decide if the meniscus line is “close enough.”
I once used a shot glass to measure 2/3 of a cup because I couldn’t find my measuring cups. Spoiler: it took way too long. But the cookies still tasted great. That’s the secret—the kitchen is a place of grace, not precision.
