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. You can make banana bread last a little longer if you store it in the refrigerator.
However, banana bread must be stored properly so that it can be placed in the refrigerator. Banana cake is a popular dessert and many people want to know how long it will last at room temperature. 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.
