It's the latest doughnut variant from JCo.
Shell doughnut with cream filling, topped with a chocolate sauce that has hints of banana flavor.
It's good, delicious. The chocolate-banana sauce has a good blend of tastes; nothing is overpowering. We just wish though that the Copabanana were a variant of the regular doughnut, not the shell one. The cream filling is just a little too much.
Perfect partner: coffee.
Try it and judge for yourself.
