I realize the combination “sweet bean” and “cake” may sound a little odd, but in Japanese okashi confectionary cuisine, sweetened adzuki beans are a traditional flavor in treats such as pastries, buns, taiyaki, and sticky red bean mochi cakes. This cake is a beautiful tribute to the sugar-dusted, jem-like sweet beans that are pressed into the cake halfway through baking. The cake itself is more akin to a torte–a simple batter made from butter, sugar, and eggs with a splash of rum to spice things up–but looks lovely and classy in a square pan. It’s a light, delicate treat for an afternoon coffee, which is exactly how I shared it with my wonderful fellows at the Koriyama City Hall Board of Education.
The recipe comes from my beloved “tiny stick cake recipe book” I first discovered at the library, and then promptly went to purchase for my own use after falling in love with the adorable wrapping and bite-size confections. If you’re making this outside of Japan, you may have to venture out to an Asian food market to find the Amanatto, or sweet beans, but here they’re readily available in any supermarket in the okashi snack aisle. I also used a special 15cm x 15cm cake pan with a removable bottom, but if you have a comparable size tart pan or springform pan, those would work just as well.
