1Start by making the banana bread. Preheat the oven to 350F.
2Grease and line a standard (9x5”) loaf pan with parchment paper. Set aside.
3Add the butter to a saucepan over medium-high heat. Allow to melt and slightly brown (~5 minutes).
4Remove from the heat, immediately pour into a large bowl, and allow it to cool slightly.
5In a medium bowl whisk together the flour, baking soda, baking powder, and salt. Set aside.
6Once the brown butter has slightly cooled, add the mashed bananas, brown sugar, greek yogurt, eggs, and vanilla. Whisk until well combined.
7Add the dry ingredient mixture to the wet. Use a wooden spoon or spatula to fold together until combined and there are no flour streaks remaining, being careful not to over-mixed.
8Fold in the chocolate chips.
9Pour the batter into the prepared loaf pan, and top with more chocolate chips/chunks if desired.
10Bake at 350F for 55-65 minutes, until golden brown and a toothpick inserted into the middle comes out clean. Let cool completely.
11Once ready to make the bread pudding, preheat the oven to 350F.
12Grease a 9” round (or 9” square) baking pan with cooking spray, then line with parchment paper that covers the bottom and sides. Place onto a baking sheet; set aside.
13Combine all of the ingredients for the custard, except for the eggs, in saucepan over medium-low heat. Whisk until the butter is melted.
14Remove from the heat and let cool slightly. Then, add the eggs one at a time, and whisk in between each addition. DO NOT cook any longer. Set aside.
15Slice the banana bread into 12 thick-cut slices, then cut into 1” cubes.
16Place 1/3 of the banana bread cubes into the bottom of the prepared pan. Press down. Then, sprinkle 1/3 of the chopped walnuts on top.
17Repeat the process 2 more times, finishing by topping with the last 1/3 of banana bread cubes and topping with the last of the chopped walnuts.
18Pour the custard all over the bread, then gently press down. Sprinkle the top with turbinado sugar.
19Allow to soak for 10-15 minutes or overnight in the fridge.
20Bake at 350F for 40-45 minutes on a baking sheet, until the top is golden and set, but still slightly wobbly.
21Remove from the oven. Rest for at least 10 min.
22If using, prepare the salted caramel by mixing all of the ingredients together in a small bowl.
23Serve warm with a scoop vanilla ice cream and a drizzle of salted caramel, if desired.
