  1. 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!

  2. 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

    1. 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:)

  4. This is a delicious cake! Mine also overflowed by about 1/3 cup in the 9×13 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.

  5. I love oats and anything to do with oats! It’s one of the few grainy types I can handle.

  6. This looks great. I have always made banana bread with the over-ripe bananas. Now I have something new to try :). Thanks for sharing.
