Equipment

Ingredients

For Banana Layer

  • 3-5 sliced bananas (I used 4 small) - not overly ripe, see notes.
  • 1/3 cup salted butter melted

Cake Mix Layer

  • 13.25 oz. yellow cake mix (I use Betty Crocker)
  • 1 cup water
  • ¼ cup vegetable oil (or any neutral oil such as canola)
  • 3 large eggs
  • 1 tsp. ground cinnamon
  • ¼ cup chopped pecans

Instructions

  • Spray the slow cooker with non stick spray. Add the brown sugar and butter. Stir together at the bottom of the slow cooker with a spoon and spread out evenly.
  • Slice the bananas half an inch thick and add enough to fill the bottom of the slow cooker.
  • In a large bowl, add the cake mix, water, oil, eggs, cinnamon and pecans. You can do this with a whisk. Do not overmix. Some lumps are fine.
  • Slowly pour the cake mixture over the bananas in the crockpot. Spread out the cake mix with a spatula carefully, being sure not to move the bananas around.
  • Place the lid on the slow cooker. Cook on HIGH for 2 hours or until the cake is firm in the center.
  • Let the cake cool for 20 minutes before flipping (or until it's cool enough to handle).
  • Run a knife around the edge of the cake. Place the platter face down over the top of the slow cooker. It is easier if you have 2 people doing this process. But can be done with one person.
    My tip for flipping with ease is to use packing tape to secure the platter on to the slow cooker. I use one big piece on each side. Use pot holders to flip over the cake onto the platter. It will be hot, so use caution.
  • Slice, serve and enjoy!

Notes

Banana Tip: For this recipe you should use bananas that are still firm. I prefer to use bananas that are slightly green or all yellow (not browning). Besides that, they will be mushy in the recipe if they are overly ripe, over ripe bananas have a strong tang that can be overbearing in recipes.
Prevent burns: This is going to be extremely hot - don't flip until letting it cool down.
