Ingredients
Method
- Preheat & Prep Pan: Adjust your oven rack to the lower third position and preheat to 350°F (177°C). This lower rack placement helps prevent the top from over-browning. Thoroughly grease an 8.5x4.5-inch metal loaf pan (or a 9x5-inch pan, noting the loaf will be slightly shorter) with nonstick spray or butter and flour. Set aside.
- Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, salt, and ground cinnamon until well combined. Set aside.
- Cream Butter & Sugar, Add Wet Ingredients:
- Using a handheld or stand mixer (paddle or whisk attachment), beat the softened butter and brown sugar on high speed until the mixture is smooth and creamy, approximately 2 minutes.
- Reduce mixer speed to medium. Add the whole egg and beat well until incorporated. Then, add the egg yolk and beat again until just combined.
- Beat in the plain yogurt (or sour cream), mashed bananas, and vanilla extract until everything is just blended. Scrape down the sides of the bowl as needed.
- Combine Wet & Dry: With the mixer on low speed, gradually add the dry ingredient mixture to the wet ingredients. Mix only until no flour pockets remain. Crucially, do not over-mix; over-mixing can result in a tough bread.
- Add Nuts (Optional): If using, gently fold in the chopped pecans or walnuts with a spatula until evenly distributed.
- Bake the Bread: Pour the batter into your prepared loaf pan and spread it evenly.
- Bake for 50-60 minutes. If you notice the top of the bread browning too quickly (often around the 30-35 minute mark for this size), loosely tent it with aluminum foil for the remaining bake time.
- The bread is fully baked when a toothpick inserted into the center comes out clean, or with only a few moist crumbs attached. Begin checking for doneness around the 45-50 minute mark, as oven temperatures and pan materials can affect baking time.
- Cool Properly: Remove the bread from the oven and let it cool in the pan on a wire rack for 15-20 minutes.
- After this initial cooling, carefully invert the loaf onto the wire rack to cool completely before slicing and serving. This prevents a soggy bottom.
- Storage: Once completely cool, cover and store the banana bread at room temperature for up to 2 days, or in the refrigerator for up to 1 week. Many find the flavor even better on the second day as the ingredients meld. (Refer to original recipe notes for freezing instructions if desired.)
Notes
- Important Update (2025 - Banana Quantity): Based on extensive retesting due to reader feedback about the bread sometimes being overly moist/dense, we've adjusted the mashed banana quantity. The recipe now calls for 1 and 1/2 cups (down from a previous 2 cups) for a consistently better bake and texture.
-
Butter:
- Salted Butter: You can use salted butter instead of unsalted with no other changes needed.
- Reduced Butter: For a slightly lighter version, the butter can be successfully reduced to 6 Tablespoons (85g).
-
Brown Sugar & Sweetness:
- This bread has a balanced sweetness. For a sweeter loaf, increase brown sugar to 1 cup (200g).
- You can substitute brown sugar with an equal amount of white granulated sugar or coconut sugar. Liquid sweeteners are not recommended.
-
Cream Cheese Frosting (Optional):
- This bread is delicious with cream cheese frosting!
- To make: Beat 4 oz (112g) softened cream cheese with 1/4 cup (60g) softened unsalted butter until smooth. Mix in 1 cup (120g) confectioners' sugar, 1/2 teaspoon pure vanilla extract, and a pinch of salt. Spread on the completely cooled loaf.
-
Banana Bread Muffins:
- This recipe yields approximately 15 muffins.
- Fill lined or greased muffin cups to the top with batter.
- Bake at 425°F (218°C) for 5 minutes, then, without opening the oven, reduce temperature to 350°F (177°C) and bake for an additional 16–17 minutes, or until a toothpick inserted in the center comes out clean.
- Total bake time: ~21–23 minutes. The initial high heat helps create taller muffins.

-
Sour Cream/Yogurt Substitutions:
-
If you don't have sour cream or plain yogurt, you can substitute with an equal amount (1/3 cup for the original recipe, adjust if scaling) of:
- Additional mashed banana
- Unsweetened applesauce
- Canned pumpkin purée
-
If you don't have sour cream or plain yogurt, you can substitute with an equal amount (1/3 cup for the original recipe, adjust if scaling) of:
-
Using Frozen Bananas:
- Frozen bananas work well. Thaw them completely, then drain off any excess liquid. Mash (some chunks are fine – avoid over-mashing into a liquid) and use as instructed.
- (See "How to Freeze & Thaw Bananas for Baking" for more detailed tips.)
- Chocolate Chips (Optional): Feel free to add up to 1 cup of your favorite chocolate chips. These can be used in addition to, or instead of, nuts.
- Bundt Cake Version: This recipe does not yield enough batter for a standard Bundt cake. For a Bundt version, I recommend using my very similar, but scaled-up, recipe for Chocolate Marble Banana Bundt Cake (the chocolate swirl is optional in that recipe).
