This banana dump cake is a favorite in my kitchen because it is nearly impossible to mess up. You just layer the ingredients in a pan, pop it in the oven, and wait for the smell to fill your home. It is perfect for those busy nights when you need a sweet treat without much effort.

My best advice is to make sure you spread your butter slices evenly across the top. This ensures that every bite gets that lovely golden, crispy texture that makes this dish so special. Serve it while it is still warm for the best experience.

🧺 Ingredients

3 ripe bananas, sliced
1 box yellow cake mix
1 cup chopped walnuts or pecans
1 cup melted butter
1 teaspoon ground cinnamon

👩‍🍳Instructions

1
Preheat your oven to 350 degrees Fahrenheit and lightly grease a 9 by 13 inch baking pan.
2
Arrange the banana slices in an even layer across the bottom of the prepared pan.
3
Sprinkle the dry cake mix evenly over the bananas.
4
Scatter the chopped nuts and the cinnamon over the top of the cake mix layer.
5
Pour the melted butter evenly over the entire surface, making sure to cover as much of the dry mix as you can.
6
Bake for 35 to 40 minutes or until the top is golden brown and the edges are bubbling.
7
Let the cake cool for a few minutes before serving.

💡 Tips

This dessert is best served warm with a scoop of vanilla ice cream. If you have leftovers, keep them in the fridge and warm them up in the microwave for a few seconds the next day.
