01 - Preheat oven to 350°F. Lightly grease a 9x13-inch baking dish with butter or cooking spray.
02 - Arrange sliced bananas in a single, even layer across the bottom of the prepared dish.
03 - Spread drained crushed pineapple evenly over the banana slices, ensuring uniform coverage.
04 - Scatter halved maraschino cherries and mini chocolate chips over the pineapple layer.
05 - Sprinkle chopped walnuts or pecans evenly across the dish if using for added texture.
06 - Pour dry yellow cake mix over the entire surface, spreading gently to create an even layer without pressing down.
07 - Pour melted butter evenly over the cake mix. Important: Do not stir or mix the layers.
08 - Bake for 40-45 minutes until the top is golden brown and the fruit filling is bubbling around the edges.
09 - Allow the cake to rest for 10-15 minutes before serving. Top with whipped cream, chocolate syrup, and additional cherries as desired.
