Banane malaxé or topsy bananas is a traditional stew originating from Cameroon. Although there are many variations, the stew is usually made with a combination of unripe bananas, ginger, garlic, onions, peanuts, hot peppers, tomatoes, crayfish, palm oil, salt, and bouillon cubes.

The ingredients are first sautéed in palm oil and then covered with water and left to simmer until everything is tender and fully cooked. The stew should be light, and as it cools down, the sauce will thicken. If desired, beef tripe or chicken can be added for extra flavor and different texture.
