Ingredients:
- 1/2 cup (113g) unsalted butter, cut into cubes (for browned butter)
- 1/2 cup (100g) granulated sugar (for salted caramel)
- 3 tablespoons (42g) unsalted butter, cut into cubes (for salted caramel)
- 1/4 cup (60ml) heavy cream (for salted caramel)
- 1/2 teaspoon sea salt flakes (Maldon or similar) (for salted caramel)
- 1 1/2 cups (192g) all-purpose flour, plus more for dusting
- 1 teaspoon baking soda
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg (optional)
- 1/4 teaspoon salt
- 1/2 cup (100g) granulated sugar
- 1/4 cup (50g) packed light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup (120ml) sour cream or Greek yogurt
- 1/2 cup (120ml) of the browned butter, cooled slightly
- 3 very ripe bananas, mashed (about 1 1/2 cups)
Instructions:
- Brown the Butter: Melt butter in a light colored saucepan over medium heat. Cook, swirling occasionally, until it turns amber and smells nutty (about 5-7 minutes). Remove from heat, transfer to a heat-proof bowl, and let cool slightly.
- Make the Salted Caramel: In a small saucepan, melt granulated sugar over medium heat, swirling occasionally, until it's a deep amber color. Add butter and whisk until smooth. Slowly pour in heavy cream, whisking constantly. Remove from heat and stir in sea salt. Let cool slightly.
- Prepare the Loaf Pan: Preheat oven to 350°F (175°C). Grease and flour a 9x5 inch loaf pan.
- Combine Dry Ingredients: In a medium bowl, whisk together flour, baking soda, cinnamon, nutmeg (if using), and salt.
- Cream Sugars, Add Eggs and Vanilla: In a large bowl, whisk together granulated sugar and brown sugar. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract.
- Combine Wet and Dry: Alternately add dry ingredients and sour cream to the wet ingredients, beginning and ending with the dry ingredients. Mix until just combined.
- Add Browned Butter and Bananas: Gently fold in the cooled browned butter and mashed bananas until just combined.
- Assemble and Bake: Pour half of the batter into the prepared loaf pan. Drizzle half of the salted caramel over the batter. Pour the remaining batter over the caramel, then drizzle with the remaining caramel. Swirl the caramel through the batter with a toothpick or skewer. Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean.
- Cool and Serve: Let cool in the pan for 10 minutes before transferring to a wire rack to cool completely. Slice and serve.
