Ingredients
- 3 large overripe bananas, mashed
- 1/3 cup unsalted butter, melted
- 3/4 cup granulated sugar
- 1 large egg
- 1/4 cup sour cream
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon kosher salt
- 1/2 cup chopped walnuts
Instructions
- 1.Mash the bananas. In a large bowl, mash the overripe bananas with a fork until mostly smooth with a few small chunks remaining. The riper the bananas, the better — brown and spotty is ideal. Black bananas are even better.
- 2.Mix the wet ingredients. Stir the melted butter into the mashed bananas. Add the sugar, egg, sour cream, and vanilla. Mix until well combined.
- 3.Add the dry ingredients. In a separate bowl, whisk together the flour, baking soda, and salt. Fold the dry mixture into the wet mixture until just combined — do not overmix or the bread becomes tough. Fold in the walnuts.
- 4.Bake low and slow. Pour the batter into a greased 9x5 inch loaf pan. Bake at 325°F for 55-65 minutes until a toothpick inserted in the center comes out clean. The lower temperature gives you a more even crumb and that dense, moist texture Starbucks is known for.
- 5.Cool completely. Let the bread cool in the pan for 15 minutes, then turn out onto a wire rack. Resist the urge to slice it hot — the texture sets as it cools, and it slices much cleaner after 30 minutes.
Starbucks Banana Bread
Starbucks banana bread is the pastry case item that sells out first every morning. It is dense, moist, and loaded with banana flavor and chunks of walnut. It is not a light, fluffy banana bread — it is a thick, rich slice that feels substantial and pairs perfectly with coffee.
A single slice at Starbucks costs $3.75-4.50 depending on your location. A whole loaf at home costs about $3 to make and yields 10 slices. That is roughly 35 cents per slice versus $4.
Why Make It at Home?
Beyond the obvious cost savings, homemade banana bread is better on every level. It comes out of the oven warm and fragrant. The Starbucks version was baked at a central facility, shipped frozen, and thawed at the store. Yours is fresh, and the difference in moisture and flavor is significant.
Tips & Variations
- The bananas must be overripe. Brown, spotty bananas have more sugar and more banana flavor. If yours are still yellow, put them in a 300°F oven for 15-20 minutes until the skins turn black. Let them cool, then use as normal.
- Sour cream is the secret. It adds moisture and a slight tang that keeps the bread from being one-dimensionally sweet. Greek yogurt works as a substitute.
- Do not overmix the batter. Stir until the flour just disappears. Lumps are fine. Overmixing develops gluten and makes the bread tough and dry.
- Add chocolate chips. Replace the walnuts with 1/2 cup dark chocolate chips for a version that is not on the Starbucks menu but probably should be.
