Now, let’s get into the baking process! Follow these simple steps to create your own delectable Dark Chocolate Chip & Walnut Banana Bread.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your banana bread bakes evenly.
Step 2: Prepare Your Loaf Pan
Grease your loaf pan with a bit of vegetable oil or line it with parchment paper for easy removal later.
Step 3: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, baking soda, and kosher salt. Set this bowl aside.
Step 4: Combine Wet Ingredients
In another bowl, mix the mashed bananas, vegetable oil, granulated sugar, and egg. Stir until well combined. Then, add the sour cream and mix until smooth.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredient mixture to the wet ingredients. Use a rubber spatula to fold everything together gently. Be careful not to overmix; a few lumps are okay!
Step 6: Fold in Chocolate and Walnuts
Now, fold in the dark chocolate chunks and roughly chopped walnuts until evenly distributed throughout the batter.
Step 7: Pour and Bake
Pour the batter into your prepared loaf pan, smoothing the top with a spatula. Bake in the preheated oven for 55-65 minutes, or until a toothpick inserted into the center comes out clean.
Step 8: Cool and Serve
Once baked, remove the bread from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a cooling rack to cool completely before slicing. Enjoy your delicious Dark Chocolate Chip & Walnut Banana Bread!
Tailor It to Your Diet

This recipe is versatile and can be adapted to suit various dietary preferences:
- Gluten-free: Substitute all-purpose flour with a gluten-free flour blend.
- Vegan: Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water) and use a plant-based sour cream.
- Less sugar: Reduce the granulated sugar by half if you prefer a less sweet bread.
- Nut-free: Omit the walnuts or substitute with seeds like pumpkin or sunflower seeds.
Troubleshooting Tips
Even the best bakers encounter issues now and then. Here are a few tips to help you troubleshoot common problems:
- Banana bread is too dense: Ensure you’re not overmixing the batter. Overmixing can lead to a tough texture.
- Uneven browning: Make sure your oven is properly calibrated. Rotate the loaf halfway through baking if necessary.
- Dry bread: Check your oven temperature. Too high can dry out the bread. Also, ensure you’re measuring your ingredients accurately.
- Not enough banana flavor: Use very ripe bananas for optimal flavor and sweetness.
Keep It Fresh: Storage Guide
Your Dark Chocolate Chip & Walnut Banana Bread deserves to be kept fresh and delicious. Here’s how to store it:
Once completely cooled, wrap the banana bread in plastic wrap or aluminum foil. Store it at room temperature for up to 3 days. For longer storage, you can freeze the bread. Just slice it first, wrap it tightly, and store it in an airtight container or freezer bag. It will keep well in the freezer for up to 3 months. To enjoy, simply thaw at room temperature or warm it up in the microwave.
Handy Q&A

How can I tell when my banana bread is done baking?
Insert a toothpick into the center of the bread. If it comes out clean or with a few crumbs, it’s done. If there’s wet batter, give it a few more minutes.
