This will make your entire house smell incredibly delicious, just like banana bread! (And it definitely tastes like it too.) 

This is such a rich and delicious dessert, it really doesn’t taste like it was made from just a few simple household ingredients! 

It kind of reminds me of a mix between a cobbler and a bread pudding.

This easy banana bread dump cake is quickly becoming one of my favorite easy dessert recipes. And, it’s a great way to use up any bananas you have on hand.

Banana Dessert ingredients

Banana Dessert Dump Cake

I love surprising my family with decadent desserts. But, I don’t always want to spend a lot of time in the kitchen preparing them. This banana dessert is so simple to make but it packs a lot of wow into it.

Why is it called a dump cake?

Dump cake describes a simple dessert that is made by simply “dumping” or layering unprepared ingredients into a baking dish. 

It’s an easy dessert that is somewhere between a cake and a cobbler. 

You really just dump the ingredients into a 9×13 ban and then bake it. There is usually no mixing involved at all. You can have this ready in just a few minutes minus the baking time.

Should dump cake be refrigerated?

Generally, dump cake is served hot or warm with a glaze, sauce, or a scoop of French vanilla ice cream. Once it’s cooled, you should refrigerate it to enjoy the leftovers another day.

Banana dump cake variations

The original banana dessert recipe that I adapted from TikTok resulted in a super sweet banana dump cake. To cut the sweetness a little bit, I did not use all of the enclosed topping mix.

Instead, I substitute a vanilla glaze that I think adds just the perfect taste without so much sweetness. I also sprinkled nuts on top. If you have someone with food allergies, you can leave those out.

There are lots of different ways you can change up the taste of this recipe. Why not try a banana chocolate chip dump cake by adding chocolate chips.

Or, make a strawberry banana dump cake by using a strawberry cake mix. The possibilities are almost endless.

Can I add nuts to the cake?

Yes, if you want to add the nuts to the banana dump cake itself, you can add them when you add the evaporated milk.

If my cake mix still looks powdery after baking, how do I fix it?

Sometimes when you make this type of banana dessert, there is still powder left on top after you bake it. No worries, it’s simple to fix.

Just add a little bit of butter to the top of the cake where you see the mix and bake it for a while longer. Just check it regularly so it doesn’t burn.

My vanilla glaze is absolutely delicious. But, if you want something easier for this banana dessert, you can add one of these instead:

Donna’s Notes

This is a great way to use up ripe bananas and ingredients you already have at home!
I only recommend using half of the cinnamon topping that comes with the cake because it is extremely sweet, especially in combination with the vanilla sauce.
If my cake mix still looks like it’s powdery after baking, how do I fix that? Just add a little more butter to the top of the uncooked cake mix, and bake for about a minute. Be sure to check often to make sure the butter has melted onto all the dry areas.
This could also be served with ice cream or topped with milk.
Can I add the nuts into the cake? Yes, just add them after you pour in the evaporated milk.
Pecans or walnuts would be great for toppings on this recipe. They do not need to be candied, as this is already a sweet and decadent dessert.
This is such a quick dessert. If you are in a hurry, this is so easy with very little prep time. If you want to make it even faster, just eliminate the vanilla sauce.
Why is it called a dump cake? This recipe gets its name because you are dumping ingredients into the pan. It’s so easy and simple!
This is not a traditional cake, so the texture is not the same. It is kind of like a mixture between a cobbler and a bread pudding.
This is the cake mix I recommend. If you use another brand of cake mix for this recipe, it may not have the same amount of mix, so just be sure to look out for that.
Don’t forget to shake up your evaporated milk before pouring it over the mashed bananas.

  1. I have a Pillsbury Sugar Free cinnamon swirl coffee cake mix. It’s only 16.4 ounces. How much should I reduce the amount of evaporated milk by to get the consistency needed? We have cut added sugar out of our diet.

    1. Hi Beth,
      Let’s calculate:
      As the recipe is written, 12 ounces (condensed milk) is 57.14 percent of 21 ounces (cake mix)
      Your cake mix is only 16.4 ounces, so your condensed milk should be 57.14 percent of that.
      57.14 % of 16.4 ounces = 9.37096 ounces
      Hope this helps!

      1. The recipe calls for evaporated milk but in your reply to Beth you are saying condensed milk.. so which it is evaporated or condensed ?
