This tropical twist on a classic cake features a layer of homemade caramel sauce and a coconut cream frosting that is both sweet and creamy. The cake itself is moist and flavorful, with a subtle banana flavor that is not overpowering. The coconut cream frosting is made with coconut cream, powdered sugar, and a touch of vanilla extract, creating a light and airy topping that perfectly complements the sweetness of the caramel and bananas.
