Creating your own Banana Split Dump Cake is a straightforward process. Follow these simple steps to ensure an incredible dessert:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease a large baking dish—approximately 9×13 inches is ideal.

2. Layer Ingredients: Start by layering the sliced bananas evenly at the bottom of the greased baking dish.

3. Add Pineapple: Next, pour the drained crushed pineapple over the banana layer, ensuring it’s spread evenly.

4. Drizzle Chocolate Syrup: Pour the chocolate syrup generously over the pineapple layer. The syrup will mix slightly with the pineapple, creating an excellent flavor combination.

5. Add Cherries: Sprinkle the maraschino cherries on top of the chocolate syrup, providing color and sweetness with each bite.

6. Sprinkle Cake Mix: Evenly sprinkle the dry yellow cake mix over the entire top layer. Ensure all the moist ingredients are covered, as this allows the cake to rise properly.

7. Pour Melted Butter: Drizzle the melted butter evenly over the cake mix layer. This will create a golden crust as it bakes.

8. Add Nuts: If using, sprinkle the chopped walnuts or pecans over the melted butter. This will add a crunchy texture that complements the softness of the cake.

9. Bake: Place the baking dish in your preheated oven and bake for 50-60 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.

10. Cool: Once baked, remove the dish from the oven and allow it to cool for about 10-15 minutes. This helps the layers set slightly and makes serving easier.
