We are full on into winter, and that means we are full on into citrus season. I am huge fan of grapefruit and finding new ways of using them. And this grapefruit cake recipe, baked in a loaf pan, is basically a grapefruit pound cake, but also basically a grapefruit buttermilk cake. And if that isn’t enough for you to take in, it’s made extra rich and moist with sour cream, so it is also kind of a grapefruit yogurt cake. Since it takes in all of that, I am just calling it a grapefruit cake.
Is grapefruit in a baked good actually good?
It really really is. While it didn’t take much convincing for me to want to try grapefruit cake, I am not gonna lie, I had to do a sh-t ton of convincing of others. I mean, we are talking about baking something bitter and sour into something light and sweet.
This grapefruit cake has all the elements of a traditional citrus cake. Think a cross between lemon and orange. Not quite as strong as lemon, and not quite as sweet as orange.
What you need to make this grapefruit cake recipe…
- a grapefruit – a big ole ripe one, that is soft(ish) to the touch. You are going to use both juice and the zest of the entire grapefruit
- oil – cause I am an oil-based-cakes only kinda girl
- buttermilk – its makes cakes oh so tender
- sugar – duhhhh
- vanilla extract – to compliment the citrus
- sour cream – for extra richness and moistness (I truly hate that word)
- and the usual’s – eggs, flour, baking powder salt
A few last things.
If you think you don’t love grapefruit in dessert, I truly hope you will consider trying this. It has such a light and bright flavor and the crumb on this grapefruit cake is absolutely perfect thanks to the buttermilk and sour cream. And if you’re super interested and already a super fan of grapefruit in desserts, here are some of my faves you should def look into…
But if you already are SO SO sure you don’t like or won’t like grapefruit, then DO NOT WORRY – cause you can totally use lemon or even better blood oranges.
Oh yeah and the glaze…the glaze! I damn near forgot about the glaze. So simple, so quick and so what you are gonna want to pour all over this grapefruit cake.

I never thought of making grapefruit cake before but it looks incredible! Will definitely be giving it a go 🙂
Looks great!!! And it looks like it is not too sweet – which I think is great for this sort of thing 🙂 Can’t wait to make this!
This cake looks like it will be my latest obsession! I live in Florida, so I’m a big grapefruit fan — and I happen to have a bag on the counter! Trying this over the weekend!
