This is a reworking of my grandmother's Barbados creams: we're going the way of the coconut and the banana. It's scarcely a fancy pudding, but sometimes it can be sweetly comforting to have something a little homespun, and almost from the nursery. This is not far from that old favourite, bananas mashed with cream and brown sugar. Hard to beat, to be sure, but the coconut yoghurt and rum certainly add a little something. You need to make these the morning of the evening you want to eat them (or the day before, if that's easier for you), but they take no more than 5 minutes to prepare. So they are very quick to make and you ease the burden on that short time after you get back from work in the evening. For US cup measures, use the toggle at the top of the ingredients list.
