Cover the cake tightly and refrigerate for up to 2 days or freeze for up to 3 months. Bring to room temperature, make the frosting, freeze and serve. Frozen or unburrowed cake freezes well, up to 3 months. Generally speaking, the banana cake will last about two days at room temperature if it is well wrapped.
However, if the cake has cream cheese frosting or any other type of frosting, it will only last one day. In addition, if the cake is stored in a very hot or humid environment, it can be damaged within two days. For example, this recipe informs in advance that the resulting loaf of banana bread only lasts a day or two on the counter. Banana bread that looks more like a banana cake than regular bread doesn't last long, and you should definitely refrigerate it.
But if it's the high-moisture variety, has a few pieces of banana scattered all over the dough, or is covered with banana halves (see my photos), you'll only have 3 to 4 days in the fridge. Banana cake is a dessert that consists of bananas, flour, sugar, butter, eggs, baking powder and vanilla extract. Banana cake is a popular dessert and many people want to know how long it will last at room temperature.
