Okay, here’s where it gets really fun. You can substitute 2/3 cup of milk with other liquids. Use 2/3 cup of water plus a splash of oil or a tablespoon of yogurt to mimic milk’s richness. Or use 2/3 cup of plain oat milk, soy milk, or almond milk—they all behave similarly in baking. The concept of 2/3 cup is universal.
So next time you see that measurement, don’t stress. Just pour a little more than half, a little less than full, and know you’re doing exactly what a thousand bakers before you have done. You’ve got this.
After all, isn’t it kind of cool that a simple fraction can transform flour and eggs into something as wonderful as a fluffy cake? That’s the quiet, curious magic of 2/3 cup of milk. Now go pour yourself some cereal—just two-thirds of the way, of course.
