I have to be honest, the coconut flavor in this banana coconut upside-down cake is very subtle, if at all noticeable. I added canned coconut milk as well as coconut milk powder and coconut rum to compensate for the lack of coconut extract but the banana took over almost all of the coconut flavor. Still, it was a delightful dessert!
How to Make Banana Upside Down Cake
Preheat your oven to 350°F (175°C), grease a 9-inch round pan with butter and set aside. I lined the bottom of my pan with parchment paper because I'm a worry wart, but I don't think it's necessary.
Melt some unsalted butter, either in a pan or microwave, and combine with brown sugar. Spread this mixture evenly into the cake pan and top with sliced bananas. I sliced my bananas about ¼ inch (0.5cm) thick.
In a small bowl, mix cake flour, all-purpose flour, coconut milk powder, salt, and baking soda. In a separate bowl, cream together the sugar and sour cream. When combined, add the coconut milk, egg, and softened butter. Add the mashed banana and coconut rum.
Add the dry ingredients to the wet ingredients and stir until just combined. Pour the batter over the sliced bananas and bake for 30 minutes, or until a toothpick inserted comes out clean. Let the cake cool for 10 minutes before inverting onto a plate.
Voilà! The parchment paper I folded and cut into a circle, unfortunately, left indentations on the bananas, but still tasted great!
The cake was incredibly moist with great banana flavor. The edges got caramelized nicely and added a slight crunch, which my brother was a big fan of. If you're not a fan of coconut, I think it'll be just as lovely if you replace the coconut milk with regular milk or more sour cream, and the coconut rum with regular rum.
If you have a few over-ripe bananas in your kitchen and you want something other than banana bread, why not try this banana coconut upside-down cake? Although, I have to say my moist banana bread recipe and gluten-free banana bread recipe are both top-notch!

Sarah says
That looks so good! Never thought about making an upside down cake with banana's 😮
Ai says
Thank you Sarah! Pineapple's the most common fruit for upside down cake (besides apples for tarte tatin) but bananas work wonderfully!

This sounds so delicious, and looks so pretty! The two overripe bananas on the counter have just caught my eye and are prodding me to finally make use of them... I'm glad to hear that someone else also puts parchment under everything. I think it sounds like quite a good idea for an upside down cake to keep anything from sticking to the pan (though rearrangement and a bit of whipped cream will fix all woes!).
Ai says
Thank you! Good to know I'm not the only one who is constantly concerned about things not coming out of the pan. (I was using a nonstick pan for this cake and I was still worried lol)
