Moist banana cake is baked up in a skillet over a layer of caramelized bananas, then topped off with powdered sugar and a scoop of ice cream for the perfect protein packed dessert or snack!
Heat oven to 400 degrees F. In a small bowl, mix together flour, baking powder, baking soda, salt and cinnamon. Set aside.
Heat a 10-inch or 12-inch cast iron skillet over medium heat. Add 3 tablespoons of butter, and let sizzle and melt, then whisk in 1/3 cup brown sugar and add in the sliced bananas in a single layer. Cook for 2-3 minutes, then remove from heat and set aside while making batter.
In a large bowl, whisk together melted butter and sugars. Once combined, whisk in eggs and vanilla until smooth. Add in dry ingredients, stirring to bring together, then add in mashed bananas and mix. Add in OP smoothie or milk and mix until combined. Pour batter over bananas in skillet and spread evenly. Bake for 30-35 minutes, or until cake is golden and set in the middle. Let cool for 5-10 minutes.
If desired, dust with confectioner's sugar and serve warm with a scoop of ice cream.
Notes
If using a 10-inch skillet, it will yield a taller cake. Begin by baking for 30 minutes and check the cake for doneness by inserting a toothpick into the center. Cake is done when the toothpick comes out with just a few crumbs or completely clean.
