I love me some grapefruit and I love me some of this cake. It came out perfectly. It's the moistest softest cake ever! And the glaze gives it the nicest subtle crunch. It's got just enough grapefruit flavor and unlike many citrus baked goodies, it's not overwhelmingly sweet. And I think I finally figured out the weirdness with my oven, I lowered the temp 25 degrees and for the first time in a while, my edges didn't get extra crispy! Hurray!
I highly recommend this little cake. And I'm sure you could swap out the fruit for whatever you'd like. I think it would be badass with lime, lemon, or orange. Or a fruit combo!
OH and in the midst of doing some dishes, I turned around to find this:
Cat on the counter. She's such a brat. She has to be in the middle of everything.
