This caramel banana cake is a delicious twist on a classic banana cake. The cake is moist and banana-y, and the caramel frosting is rich and buttery. The bananas are mashed and mixed into the cake batter for added flavor and moisture. The caramel sauce is made by cooking sugar until it turns a deep amber color, then adding cream and butter. The result is a rich and buttery caramel sauce that pairs perfectly with the banana cake. This cake is perfect for any occasion.
