Delicious upside-down peanut butter banana bread bars made with ripe bananas, brown sugar, and dark chocolate, topped with a caramel sauce. Perfectly baked for a delightful dessert.
1: Preheat the oven to 375˚F and grease a 9 by 13-inch pan with nonstick spray and line with parchment. Place the sliced bananas cut side down on the parchment.
2: In a medium saucepan, combine the sugar and water over medium-high heat until an amber caramel forms, about 6 to 8 minutes, then pour over the bananas.
3: In a large bowl, whisk together the brown sugar and mashed bananas until smooth. Then whisk in the olive oil, peanut butter, vanilla, and eggs until well incorporated.
4: Add the flour, salt, baking soda, baking powder, cinnamon, and nutmeg, stirring until just incorporated. Fold in the dark chocolate if using.
5: Pour the batter over the caramel-coated bananas and smooth with a spatula. Bake for about 30 minutes until golden and cracked with an internal temperature of 190°F.
6: Let cool for 15 minutes, then run a knife along the edges. Invert onto a platter or cutting board, remove parchment, and slice to serve warm.
