I first got the idea for this cake when watching The Great British Bake Off in the fall. I can’t remember exactly what dessert they were doing, but I think each contestant had to make their own version of an upside-down cake. I started thinking about what I might like in an upside-down cake that would be different than the normal apple or pineapple upside-down and bananas came to mind. To make it unique I thought that adding chai spices (cinnamon, cardamom, ginger, allspice and cloves) would be a nice addition. I hadn’t made too many upside-down cakes before, so I did a search on the internet to see if there were any banana upside-down cakes that looked good. I found a recipe on food52.com that looked promising. It used buttermilk and was cooked in a cast iron skillet, which I liked.
I decided to add a mix of spices to the caramel-banana mixture that would be the top of the cake. The first time I made it, I also happened to have some chopped pistachios and sprinkled those over the caramel before adding the bananas. This turned out really well, but shelling and chopping pistachios is a pain, so I’m making that an optional addition in this recipe. We all loved the cake, it rose really well and had a tender crumb and the caramel-banana mixture on top was outstanding!
In the spirit of full disclosure, when I made this recipe yesterday, I made two big mistakes. First I accidentally used my 12-inch skillet instead of my 10-inch skillet, which in itself wouldn’t have been a huge deal. However my second mistake was that I got distracted by my kids having an argument and I didn’t put enough baking powder in the cake. To be honest, I’m not sure if I put any! This made for a very flat pancake-like thing, rather than a fluffy cake. It was still delicious, however the texture was a little off-putting. I have made this cake several times before though and each of those times came out well!
If you don’t have buttermilk, you can make sour milk by adding 2 tsp of white vinegar to your milk.

A less flat version that has pistachios. I sprinkled on extra pistachios after baking for colour.
