Method
Preheat and prep
- Preheat the oven to 350°F (175°C) and set a rack in the middle position, so the loaf bakes evenly with a stable heat.
- Grease and line a 9×5-inch loaf pan with parchment paper to prevent sticking and ensure clean slices.
Mix dry ingredients
- In a bowl, whisk together the all-purpose flour, baking soda, baking powder, salt, and ground cinnamon until evenly combined and no streaks of spice remain.
Mix wet ingredients
- In another bowl, whisk the mashed very ripe bananas, melted unsalted butter, light brown sugar, large eggs, bourbon, and vanilla extract until glossy and smooth.
Combine and bake
- Fold the wet ingredients into the dry ingredients until just combined, stopping as soon as you no longer see dry flour for a tender crumb.
- Stir in the chopped toasted walnuts so they distribute through the batter.
- Pour the batter into the prepared loaf pan and level the top for even rise.
- Sprinkle with coarse sugar if desired to create a lightly crisp, sweet crust.
- Bake for 55–65 minutes, or until a toothpick inserted into the center comes out clean, then watch for a deep golden top and set edges.
Cool and serve
- Cool the loaf for 15 minutes before removing from the pan so the crumb firms up for clean slicing.
- Slice and serve warm with butter or honey for a soft, aromatic bite.
Notes
For the best texture, use very ripe bananas and mash them thoroughly so the batter stays moist without lumps. Store airtight at room temperature up to 3 days or refrigerate up to 6 days; freeze slices up to 2 months. For a lower-sugar option, reduce brown sugar to 1/2 cup and increase vanilla slightly for flavor while keeping the banana-forward taste.
