These were surprisingly interesting. I took the suggestion of others and doubled the grapefruit juice. The batter was quite lumpy (which had me worried) but the "bars" (I would call them cake) came out extremely moist and yummy, with no lumps. I am also going to make a grapefruit frosting (grapefruit juice, cream cheese, powdered sugar, vanilla, milk) to put on top.
