Bananas Foster Frosting is a rich and creamy frosting with the flavors of the classic New Orleans dessert. The frosting is made with ripe bananas, brown sugar, and rum, which are cooked together to create a caramelized banana sauce. The sauce is then mixed with butter and powdered sugar to create a smooth and flavorful frosting. This frosting is perfect for topping cakes, cupcakes, or even spreading on cookies.
