Recipe from Smitten Kitchen. The recipe on her site is for blood orange olive oil cake, which is also good, but the grapefruit recipe is in her cookbook (which I would definitely recommend purchasing if you don’t already have it).

In my opinion this cake is delicious without the syrup or the glaze, but I tend to like things less sweet in general.
