Recipe by ReeLani

Found this in a local newspaper and scribbled it down. I've had lots of lemon poppy seed cake but never heard of one made with grapefruit. I haven't tried this yet but am looking forward to it.

A very tasty cake, not overwhelmingly "grapefruit-y". Like KrabKokonas, I would recommend doubling the peel for more citrus flavor and increasing the % of grapefruit juice. Didn't have any buttermilk, so combined whole milk with the juice to sour it. We found that this cake was better eaten the first day or two.
