Starbucks Banana Bread
This copycat Starbucks banana bread delivers the same moist, tender loaf you love from the coffee shop — made right in your own kitchen with simple pantry staples. Incredibly ripe bananas, a touch of buttermilk, and the perfect baking temperature combine to create a golden-crusted, soft-crumbed loaf that rivals anything you'd buy at the counter, at a fraction of the cost.
Equipment
- 9x5-inch loaf pan - 23x13cm; proper size ensures even baking
- Two mixing bowls - One for dry ingredients, one for wet
- Whisk - For combining dry ingredients
- Fork or potato masher - To mash bananas to the right consistency
- Measuring cups and spoons - For accurate ingredient measurements
- Rubber spatula - For folding batter and scraping the bowl
- Parchment paper - (optional) Makes removal and cleanup easier
- Cooling rack - Allows proper air circulation during cooling
- Toothpick or cake tester - To check doneness
Ingredients
- 2 cups all-purpose flour - 250g; spooned and leveled
- 1 tsp baking soda - 5g
- 1/4 tsp salt - 1.5g
- 1/2 cup vegetable oil - 120ml
- 1 cup granulated sugar - 200g
- 1 large egg - room temperature
- 3 tbsp buttermilk - 45ml; substitute: 3 tbsp milk + 1/2 tsp white vinegar, let sit 5 minutes
- 1 tsp vanilla extract - 5ml
- 3 very ripe medium bananas - about 1 1/4 cups or 300g mashed; heavily spotted for best flavor
- 1/2 tsp ground cinnamon - (optional) 2g; adds warmth and depth
Optional Add-Ins & Topping
- 1/2 cup chopped walnuts or pecans - (optional) 60g for batter; reserve extra 1/4 cup (30g) for topping
Instructions
- Preheat oven to 325°F (165°C) and position the rack in the center. Grease a 9x5-inch loaf pan with butter or non-stick spray, then optionally line with parchment paper and dust lightly with flour.
- In a medium bowl, whisk together the flour, baking soda, salt, and cinnamon (if using) for about 30 seconds until evenly combined. Set aside.
- In a large bowl, lightly beat the egg, then add the sugar and vegetable oil and mix vigorously for about 1 minute until smooth and slightly thickened.
- Peel the ripe bananas and mash thoroughly with a fork or potato masher until mostly smooth with just a few small lumps — you should have about 1 1/4 cups (300g).
- Add the mashed bananas, buttermilk, and vanilla extract to the sugar-oil-egg mixture and stir until smooth and well combined, scraping down the sides of the bowl.
- Pour all the dry ingredients into the wet mixture at once and gently fold with a rubber spatula just until no dry streaks remain — do not overmix. If using nuts, fold in 1/2 cup now.
- Pour the batter into the prepared loaf pan, spread evenly, and tap the pan on the counter 2–3 times to release air bubbles. Sprinkle reserved nuts over the top if desired.
- Bake for 60–75 minutes, checking at the 60-minute mark; the bread is done when deep golden brown and a toothpick inserted in the center comes out with just moist crumbs. Tent with foil if the top browns too quickly.
- Cool in the pan on a wire rack for 10–15 minutes, then transfer to the rack and cool at least 1 hour before slicing for clean cuts.
Notes
- Use bananas with heavily brown-spotted peels for the sweetest, most flavorful bread — the riper the better.
- Do not overmix once you add the flour; stir just until the dry streaks disappear to keep the bread tender.
- No buttermilk? Make your own by combining 3 tablespoons of milk with 1/2 teaspoon of white vinegar or lemon juice and letting it sit for 5 minutes.
- Measure flour correctly by spooning it into the measuring cup and leveling off — scooping directly compacts the flour and can make the bread dense.
- Check your baking soda freshness by dropping a small amount into vinegar; it should bubble vigorously.
- If bananas aren't ripe enough, bake them in their peels at 300°F (150°C) for 15 minutes to speed up ripening.
- Don't open the oven door before the 50-minute mark — releasing heat can cause the bread to sink in the center.
- Store wrapped tightly at room temperature for 2–3 days, refrigerated for up to 6 days, or freeze for up to 3–4 months.
- Freeze individual slices wrapped separately for easy grab-and-go portions; microwave for 10–15 seconds to warm.
- For variations, fold in 3/4 cup chocolate chips, 1 cup blueberries, or 1/2 cup shredded coconut in place of or in addition to the nuts.
