Ingredients
Scale
Dry Ingredients
- 1 1/2 cups all-purpose flour
- 1 tsp baking soda
- 1/2 tsp salt
Wet Ingredients
- 1/2 cup unsalted butter, softened
- 3/4 cup granulated sugar
- 2 large eggs
- 1 cup mashed ripe bananas (about 2-3 medium bananas)
- 1/4 cup sour cream
- 1 tsp vanilla extract
Chocolate Mixture
- 1/4 cup unsweetened cocoa powder
- 1/4 cup semi-sweet chocolate chips
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan to prevent sticking and ensure easy removal.
- Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, and salt to distribute the leavening agents evenly throughout the flour.
- Cream Butter and Sugar: In a large bowl, use an electric mixer to beat the softened butter and sugar until the mixture is light and fluffy, which will help create a tender crumb in the bread.
- Add Wet Ingredients: Beat in the eggs one at a time, making sure each is fully incorporated. Then add mashed bananas, sour cream, and vanilla extract, mixing well to combine all flavors.
- Combine Dry and Wet Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing just until combined to avoid overworking the batter and resulting in a dense loaf.
- Prepare Chocolate Batter: Divide the batter in half. Into one half, fold in the cocoa powder and semi-sweet chocolate chips to create the chocolate portion of the marble bread.
- Swirl the Batter: Spoon the plain banana batter and the chocolate batter alternately into the prepared loaf pan. Use a knife or skewer to gently swirl the two batters together for a beautiful marbled effect.
- Bake: Bake the loaf in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean, indicating the bread is fully cooked.
- Cool the Bread: Let the bread cool in the pan for about 10 minutes to firm up, then transfer it to a wire rack and cool completely before slicing to maintain its structure and flavor.
Notes
- For best flavor, use very ripe bananas with brown spots for natural sweetness and moisture.
- Do not overmix the batter once the dry ingredients are added to keep the bread light and tender.
- Check the bread at 50 minutes; if a toothpick doesn’t come out clean, bake for an additional 5-10 minutes.
- Sour cream adds moisture and helps keep the bread soft, but plain yogurt can be substituted if necessary.
- Store leftover banana bread in an airtight container at room temperature for up to 3 days or freeze for longer storage.
