There are so many different kinds of fruit that I want to turn into cupcakes! This week Dylan challenged me to create a cupcake using grapefruit. Challenge accepted! Grapefruit is known for its citrus sweet, yet bitter flavor. If I’m having one for breakfast I usually sprinkle sugar on top to sweeten it up a bit. We’ve made lemon and lime cupcakes, which are also sweet/sour/bitter, and they’ve all turned out delicious, so I figured these would turn out similar.
For the beer, we wanted to use something light, so we went with Deschutes Twilight Summer Ale. This beer was a perfect match for the grapefruit, it has a very crisp, citrus-like taste to it and just enough hops to add some bitter. This beer is great for a very hot day, or for a day of baking (like we so often do at our house!)
The cake is pretty simple, and if you have a good recipe for lemon cake, you can pretty much substitute any lemon ingredients with grapefruit. That’s what I did, and I added a bit more grapefruit zest just to make sure the flavor came through. The cake turned out super soft and the grapefruit flavor was definitely there. For the frosting I made grapefruit buttercream using reduced grapefruit juice and more zest. You still get some of the bitter from the grapefruit, but all the powdered sugar in the frosting balances it out.
To top them all off, I candied some grapefruit peel, which turned out surprisingly good. I’ve never attempted to candy anything, so I was pleased with the outcome (and it tasted awesome). If I candy anything again I’d probably cut the peels a bit thinner, but that’s only for aesthetic reasons. After putting the entire cupcake together, Dylan and I each took a bite and declared victory. I would definitely make these again, and look forward to it in the future!
