Doubling 1/3 cup is exactly 2/3 cup. Yes, it’s that easy. You don’t need to summon Pythagoras or consult a mystical cooking app.
Think of it this way: if you have one lovely slice of a three-slice pie, doubling it gives you two slices of that same pie. That’s 2/3 of the whole pie. Congratulations, you’ve just mastered elementary math. Your future cookies thank you.
The “But My Measuring Cup is Confusing” Excuse
I hear your kitchen sobs. Your ⅓ cup measure is just a tiny plastic scoop that looks like it’s from a dollhouse. You fill it once, then again. That’s two of those mini-scoops. Done.
If you prefer lazy solutions, grab a ⅔ cup measure if you own one. You do? Then use it and feel like a kitchen wizard. If you don’t own one, you now have permission to buy one. Your next baking session will be 10% less stressful.
