You read that right. This is a cake that uses an entire orange. Two of them, actually–zest, pith, flesh, and all, blitzed into a chunky puree and folded right into the batter. It’s the orangiest orange cake I’ve ever had, and I’m pretty smitten.
I was introduced to the whole-orange cake idea when a friend texted me a photo of a recipe page in a magazine and challenged me to try it. The resulting cake was a hit: suffused with orange flavor and shot through with flecks of zest. But it was also a pain in the ass to make. It required beating egg whites and yolks separately, thus dirtying three bowls and a food processor by the time I’d finished. After we licked the cake plate clean, I stared at the sink full of dishes and decided to look for a better solution.
This version, which I found on Food52, checks all the boxes. It’s a snap to make, requiring one bowl plus a food processor or blender. It’s got an intensely orangey flavor, fragrant and slightly bitter, with lots of those chewy zest-flecks that I love. The texture is fluffy and moist, but still dense enough to qualify as a classic bundt cake. (I’ve taken to swapping out a bit of the butter for olive oil, both for flavor and to keep the cake from drying out after it’s cut.) It’s simple, attractive, just the kind of thing you want as an after-dinner treat when company’s over. I’ve even served it as a birthday cake, and it was greatly appreciated.
The original recipe calls for an orange juice glaze to top the cake. I use lemon juice instead, so that the crackly surface has some sharpness to contrast with the bittersweet cake underneath. And while I love the plain orange-ness of this cake, you could certainly use this as a canvas for all sorts of flavors. Maybe next time I’ll blitz some fresh rosemary or anise seeds in with the oranges, or swap out the vanilla extract for almond. And I haven’t yet tried this with other citrus–I suspect the recipe will require some tweaking–but will report back if I do.
