How Many 2/3 Cups Equal 1/4 Cup?
Alternatively, if you’re feeling rebellious, use three 1/3 cups. That’s literally the same thing but with less mental gymnastics. Or, go full anarchist and just eyeball it. Has anyone ever died from a slightly-off flour-to-sugar ratio? Probably not. But don’t quote me on that.
