Ingredients
  

Moist Banana Bread Ingredients
  • 1 1/2 cups heavily speckled, very ripe bananas Mashed gently to leave small chunks visible.
  • 1/2 cup neutral vegetable oil Canola oil works perfectly as well.
  • 1/4 cup full-fat sour cream Essential for tenderizing the dense crumb.
  • 3/4 cup packed dark brown sugar Provides deep moisture and caramel notes.
  • 1/4 cup granulated sugar Helps form the gorgeous golden-brown crust.
  • 2 large eggs Must be brought fully to room temperature.
  • 1 tbsp pure vanilla extract Do not use imitation vanilla.
  • 1 3/4 cups all-purpose flour Measured precisely with a kitchen scale.
  • 1 tsp baking soda Ensure it is fresh for the best rise.
  • 1/2 tsp fine sea salt Balances the sweetness of the bananas and caramel.
  • 1 cup thick canned dulce de leche Divided evenly for the interior swirl and the final top drizzle.

Equipment

  • 1 9x5-inch (23x13cm) Metal Loaf Pan Essential for proper heat distribution and a deeply golden-brown crust.
  • 2 Large Glass Mixing Bowls For properly whisking the wet and dry ingredients.

Method
 

Preparing and Baking the Banana Bread
  1. Preheat your oven to 350°F (175°C). Lightly spray a 9x5-inch (23x13cm) metal loaf pan with non-stick spray and line it tightly with a parchment paper sling.
  2. In a medium bowl, carefully mash the heavily speckled bananas with a fork. Leave small chunks behind so the flecks of mashed banana remain visible in the baked texture.
  3. In a large mixing bowl, vigorously whisk together the mashed bananas, vegetable oil, full-fat sour cream, dark brown sugar, granulated sugar, room temperature eggs, and vanilla extract until completely uniform.
  4. Sprinkle the all-purpose flour, baking soda, and fine sea salt over the wet mixture. Gently fold the batter together using a silicone spatula until just combined. Do not overmix.
  5. Pour exactly half of the batter into your prepared pan. Warm 1/2 cup (150g) of dulce de leche in the microwave for 15 seconds, drop dollops over the batter, and swirl generously with a butter knife in a figure-eight pattern. Pour the remaining batter on top.
  6. Bake on the center rack for 55 to 65 minutes. Watch for a deeply golden-brown crust. If it browns too quickly, cover loosely with an aluminum foil tent. A toothpick inserted into the center should come out with a few moist crumbs.
  7. Allow the bread to cool in the pan for 15 minutes before transferring to a wire rack to cool completely. Once room temperature, warm the remaining 1/2 cup (150g) of dulce de leche and drizzle it heavily across the top crust.

Notes

For maximum moisture retention, ensure you use oil and full-fat sour cream as written. Do not substitute with butter or low-fat dairy.
To prevent the bread from sinking, never open the oven door during the first 40 minutes of the baking process.
