Peanut Butter-Banana Upside Down Cake

Sharing is caring!

Peanut Butter-Banana Upside Down Cake has lots of sliced bananas which get wonderfully caramelized during baking thanks to a mixture of dark brown sugar and butter. Peanut butter and banana lovers will adore this unique take on Pineapple Upside Down Cake. This cake is even better served warm with a scoop of vanilla ice cream.

This delicious Peanut Butter-Banana Upside Down Cake gets made in a 10-inch cast iron pan which helps the butter and brown sugar caramelize and develop a really wonderful flavor.

To make this upside down cake, a mixture of butter and dark brown sugar gets spread in the bottom of the pan. Then bananas that have been sliced in half lengthwise get arranged in a pretty pattern. You want to use medium-ripe bananas for best results. They should be all yellow, or yellow with just a little brown.

Next a batter with a full cup of peanut butter gets spread on top. Bake for 1 hour, let cool 10 minutes, and then invert onto a serving platter. I think it tastes best when served warm with ice cream. The texture is dense and so moist.

If you don’t have a 10-inch cast iron pan, you can use a 9-inch cake pan but you will have a little extra batter and you will have to adjust the cook time. The extra batter can be baked in a small loaf pan or a muffin tin.

  1. Oh my god this looks SO good! I’ll have to figure out how to make it gluten free- it can’t be too hard. Maybe just up the milk to 1 cup instead of a half and use a little less flour.
