At room temperature, this cranberry bundt cake keeps well for 3 days. Beyond this time, I recommend storing in the chiller to extend its freshness due to the fruit and dairy content in the cake. Before storing, make sure the cake has completely cooled to room temperature. Pop chilled slices into a microwave oven, and heat at medium power for 15 to 20 seconds to get it as tender and moist as when first baked.
