  1. Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x13 pan. Place marshmallows in a single, even layer in the bottom of the pan.
  2. Sift together flour, salt, baking soda, and baking powder. Set aside.
  3. In a large bowl, cream together the margarine and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla. By hand, stir in the flour mixture alternately with the buttermilk, mixing just until incorporated. Fold in nuts and bananas.
  4. Pour batter over marshmallows, making sure that marshmallows are covered, and that the batter reaches all sides of the pan.
  5. Bake on center rack of oven for 45 minutes. Marshmallows will rise to top and make a topping. The cake may look slightly underbaked because of the marshmallow topping. Allow the cake to cool before serving.


  • Tip
  • Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

Delicious and very moist. Lots of banana flavor! Nice change from banana bread. Halved recipe, except buttermilk (used 1/2 cup) and baked in 9"x9" pan. Substituted single layer of miniature mars...

We really liked this. I didn't have any buttermilk so used ordinary milk with 1/2 T of vinegar added. I also didn't use the nuts. I had no trouble with the marshmallows burning although my cake ...

The recipe would be great without the marshmallows. Mine rose to the top as the recipe said they would, but they burnt to a toasty crisp. Even if they wouldn't have burnt, they let large holes f...

This was amazing. Yes, its didn't look great, but it tasted out of this world. The entire cake was consumed by 4 of us the same night. I just could not get enough of the taste of this. If you a...

MMM!! this was really good.

This cake is definitely tasty! However I will call it Ugly Cake instead of Picnic Cake. I had read several reviews beforehand though so it wasn't any surprise. I'm really glad I did because if...

Made this for a day of boating. This cake was great-no frosting so it was easy to transport and everyone enjoyed it. Six year old nephew licked the pan! I prepared as written but after reading...

This is a pretty delicious banana cake, fluffy and moist. Used almonds, just great! Got surprised by its flavor.
