Fruity upside-down cakes are a perfect way to use seasonal fruit in a cake. When I was a kid, pineapple upside-down cake was my favorite cake and was usually my birthday cake request. Back then I didn’t know that you could make an upside-down with other fruits, I thought it was only a pineapple cake. These days I know better and will make them with a variety of fruits: berries, apples, pear, banana, persimmon, peaches/nectarines, mango, etc.
There’s something irresistible that the caramelized mix of butter, brown sugar and fruit will add to a simple cake. For this rhubarb upside-down cake I also added chunks of rhubarb to the cake batter. This cake batter recipe is adapted from my friend Rossana’s yogurt vanilla cake. It’s a simple no-fail cake recipe that is so easy to customize with your favorite fruit.
I also the way you can play around with the pattern of how you arrange the rhubarb slices on the bottom of the cake mold. You can get very creative or just put them in a simple way. The rhubarb pieces will reduce when the cake bakes, so feel free to really stuff them in and make the pattern as tight as you want.
Also, the edges of the cake tend to get more caramelized/darker so if you have rhubarb stalks with different colors (usually ranging from dark green to reddish/pink) then add the more boring-colored pieces (ie the green ones) on the edges. Then place the more brightly colored ones in the center.
