These Guava filled Coconut Cupcakes can be stored covered and at room temperature for one to two days. Just keep in mind the frosting may weep or be very soft, especially if they are in warmer temperatures. I prefer to refrigerate them covered for up to four to five days. This option makes me feel better especially because there is cream cheese in the frosting and dairy can spoil if it sets out too long. I also love to wrap extra cupcakes in plastic wrap and freeze them. They are perfect as a midday snacks and can be frozen for up to three months.
