Banana Upside Down Cake
How to Video
Equipment
- non-stick cooking spray
- oval platter
Ingredients
For Banana Layer
- 3-5 sliced bananas, (I used 4 small) – not overly ripe, see notes.
- 1/3 cup salted butter, melted
- 1 cup brown sugar
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!

Recipe sounds great and Iโd love to try it, but I canโt find how much brown sugar it calls for? In the video it looks like maybe a cup?
Yes, it’s one cup!
