1. Preheat the Oven

• Set your oven to 350°F (175°C).

• Grease a 9×5-inch loaf pan with non-stick spray or line it with parchment paper.

2. Mix the Wet Ingredients

• In a large mixing bowl, combine mashed bananas and melted butter.

• Stir in granulated sugar, eggs, and vanilla extract until smooth and well-blended.

3. Combine the Dry Ingredients

• In a separate bowl, whisk together flour, baking soda, and salt.

4. Make the Batter

• Gradually fold the dry ingredients into the banana mixture.

• Stir just until combined—do not overmix.

5. Add Nutella Swirl – Layer 1

• Pour half of the batter into the prepared loaf pan.

• Drop spoonfuls of Nutella over the batter.

• Use a butter knife to gently swirl the Nutella into the batter.

6. Add Second Layer

• Pour the remaining batter on top.

• Add more spoonfuls of Nutella and swirl again.

7. Bake

• Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.

• If the top begins to brown too quickly, loosely tent with foil after 40 minutes.

8. Cool and Serve

• Let the loaf cool in the pan for 10 minutes.

• Transfer to a wire rack and cool completely.

• Slice and enjoy!
