Banana Oatmeal Cake Recipe

This moist Banana Oatmeal Cake is made with banana and oats. It’s so delicious you might want to eat for dessert AND breakfast!

Banana Oatmeal Cake sitting on a cutting board.

I guess I am like a lot of you – I get so many good recipes from my mother.  This Banana Oatmeal Cake is one of them.  (Thanks, Mom!)

Whenever I have bananas that are starting to become a little too ripe, I like to make this Banana Oatmeal Cake. I confess that I have eaten this for breakfast.

A few weeks ago I received Foods That Harm, Foods That Heal:  The Best and Worst Choices to Treat Your Ailments Naturally from Reader’s Digest.  The paperback book retails for $19.99 and has 389 pages filled with information about, well, what else –  foods that heal and foods that harm.

What I like about the book is that it is divided into three parts.  The first section has information on nutrition, vitamins, additives, fats, food safety, organics, pesticides, and more.

So what does that have to do with Banana Oatmeal Cake?  Well, read on.

The second part of the book contains foods listed alphabetically and tells you what they are good and bad for.  Although we all know that oats are good for us, I thought I would look them up in the book to see what it states.  It lists the following as health benefits of oats:

  • reduces the risk of heart disease
  • manages cholesterol levels
  • lowers blood pressure
  • prevents diabetes
  • helps bowel regularity
  • aids weight loss.

For how it harms:  blood sugar spike.  If you are like me, you want to question that.

I read on and it further explains “Unlike steel-cut or whole oat products, instant oatmeal ranks high on the glycemic load and can cause blood sugar to spike  Instant oatmeal can also contain higher levels of sodium, compared to the steel-cut version.”

The third section is categorized according to ailments.  Have hypertension?  Turn to page 235 and you will see that salty and processed foods are harmful.

Foods that are beneficial are green leafy vegetables, low-fat dairy products, legumes, fruits (especially bananas), nuts and seeds, whole-wheat pasta, carrots, and sweet potatoes.   [Hey – this cake has bananas!]

I have made this twice now and both times were AMAZING! I made one for my sin for his bday and added some chocolate chips. It was delicious he said. I'm going to add some apples this time around and see how good it turns out. Thank you for sharing such a great cake!

Would like to double recipe and bake in a 9 x 13 pan. Has anyone tried this? And, for how long should I bake it... Absolutely love this cake...obviously

I am glad you love the recipe!

If you or anyone else tries it, please come back and let us know how it turns out.

From what I have read online, you should be able to double it. However, it will probably take longer to bake. According to King Arthur Flour, "the Classic Birthday Cake made in a 9” x 13” pan, bake it for 45 to 48 minutes at 325°F until it tests done." The baking time will also vary depending on the type of pan being used: glass, metal, etc.

Made this twice a couple of nights ago (stupidly didn't bookmark this site so took me til now to find you again!) and it is fabulous. First batch made as written, but second time 'round tried olive oil in place of butter and halved the sugar since my bananas were bordering on black anyway, so very sweet. I also threw in a few walnuts and added a bit more spice (nutmegs, cloves, ginger) for a little kick. Thank you - will be making it often:)

This is a delicious cake! Mine also overflowed by about 1/3 cup in the 9x13 inch pan, but I will make it again and just not fill it as much. I did do the freezer trick, but was a bit concerned about the hot cake raising the temp of the freezer and leading to decreased food quality. Anybody with any info on this? I omitted the walnut topping but added 1/2 tsp of cinnamon...YUMMY! Thanks for a keeper recipe.
