01 - Preheat the oven to 350°F. Lightly grease a 9x13-inch baking dish with cooking spray or butter.
02 - Arrange the sliced bananas in an even layer across the bottom of the prepared baking dish.
03 - Spread the drained crushed pineapple evenly over the banana layer, covering completely.
04 - Distribute the halved maraschino cherries evenly over the pineapple layer.
05 - Evenly sprinkle the granulated sugar over the entire fruit layer to enhance sweetness.
06 - Scatter the semisweet chocolate chips evenly across the fruit and sugar mixture.
07 - Pour the dry yellow cake mix over the fruit and chocolate, spreading it into an even layer without stirring.
08 - Drizzle the melted butter evenly over the cake mix, ensuring as much surface area as possible is covered for a golden crust.
09 - Bake for 40-45 minutes until the top is golden brown and the edges are bubbly. The center should be set with slight moisture.
10 - Let the cake cool for at least 15 minutes before serving. Top with whipped cream, chopped nuts, extra cherries, and chocolate syrup as desired.
