There’s nothing like the smell of bananas and chocolate mingling in a warm kitchen to make me feel like I’m wrapped in a blanket. I make this Double Chocolate Banana Bread when the bananas start turning spotty and the house feels like it needs a hug — the oven fills the room with a rich, cozy aroma, and the crust sings a soft cracking sound when I slice it. Every loaf comes out meltingly tender inside with pockets of gooey chocolate and slightly crisp edges that I fight my family over. This recipe feels like comfort food with a little extra drama: two kinds of chocolate, hearty banana sweetness, and a texture that stays moist for days.

Why This Recipe is Awesome
This loaf gives you the best of both worlds: tender, banana-forward crumb and intense chocolate pockets that melt into bites. It’s forgiving, never dry if you follow the simple tips, and it smells like happiness. Also, it’s so easy even your oven can’t mess it up — just mash, fold, pour, and let the heat do the rest. Who doesn’t love crisp edges and a soft, gooey center?
Ingredients
For the Main Dish:
- 1 3/4 cups all-purpose flour
- 1/3 cup unsweetened cocoa powder
- 1 tsp baking soda
- 1/2 tsp fine salt
- 1/2 cup unsalted butter, melted and slightly cooled (1 stick)
- 1/2 cup granulated sugar
- 1/2 cup light brown sugar, packed
- 2 large eggs, room temperature
- 1 tsp pure vanilla extract
- 3 very ripe bananas (about 1 1/2 to 1 3/4 cups mashed)
- 1/2 cup sour cream or plain Greek yogurt
- 1 cup semi-sweet chocolate chips (plus 1/4 cup extra for sprinkling)
- Optional: 1/2 cup chopped walnuts or pecans
For the Sauce / Garnish (if applicable):
- Optional dusting of powdered sugar or a drizzle of melted chocolate for extra shine.
How I Make It
Step 1:
Heat the oven to 350°F. Grease a 9×5-inch loaf pan and line it with parchment so you can lift the loaf out easily. In a bowl, whisk together 1 3/4 cups flour, 1/3 cup cocoa powder, 1 tsp baking soda, and 1/2 tsp salt. The cocoa should look velvety and deep brown — it gives the bread that chocolate backbone.
Step 2:
In a large bowl, whisk the melted 1/2 cup butter with both sugars until glossy. Add the 2 eggs and 1 tsp vanilla, and beat until smooth. Mash the 3 ripe bananas with a fork until chunky-smooth and stir them into the wet mix along with 1/2 cup sour cream. The batter smells sweet and tropical at this point — absolutely irresistible.
Step 3:
Fold the dry ingredients into the wet with a spatula until just combined. Don’t overwork it — a few streaks of flour are fine. Fold in the 1 cup chocolate chips and optional nuts. The batter should be thick, glossy, and studded with chocolate.
Step 4:
Pour the batter into the prepared pan and smooth the top. Scatter the extra 1/4 cup chocolate chips on top. Bake for about 60 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs attached (not wet batter). The edges should look set and a little shiny; the top will puff and show tiny cracks. If the top browns too quickly, tent with foil after 35–40 minutes.
Step 5:
Cool the loaf in the pan for about 10 minutes, then lift it out using the parchment and cool another 15–20 minutes on a rack before slicing. Warm slices taste incredible, with chocolate that strings and a crumb that practically melts. If you’re patient, the flavors tone down and slice cleaner after a few hours.
Pro Tips
- Use very ripe bananas (lots of brown spots) for maximum sweetness and moisture.
- If your bananas aren’t sweet enough, add 1–2 tbsp of maple syrup or honey to the wet mix.
- Replace half the chocolate chips with chopped dark chocolate for pockets of molten richness.
- Swap 1/2 cup sour cream for an equal amount of plain Greek yogurt for a tangy lift and extra moisture.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Butter ↔ coconut oil: Use melted coconut oil 1:1 for a dairy-free version (adds a subtle coconut note).
- Sour cream ↔ applesauce: Use unsweetened applesauce for lower fat; expect a slightly lighter texture.
- All-purpose flour ↔ 1-to-1 gluten-free flour: Use a cup-for-cup gluten-free blend — texture stays similar but let the batter rest 10 minutes before baking.
- Dairy-free: Use dairy-free yogurt and dairy-free chocolate chips to make this fully dairy-free.
Variations & Tips
- Add 1 tsp cinnamon and a pinch of cayenne for a warm, spicy kick.
- Stir in 1/2 cup shredded coconut for texture and a tropical twist.
- Make mini loaves — bake 20–28 minutes at the same temperature until a toothpick comes out mostly clean.
- Swirl in 1/3 cup peanut butter for a chocolate-peanut butter explosion.
- Top with a sprinkle of flaky sea salt for a sophisticated, salty-sweet finish.
- Try espresso powder (1 tsp) in the batter to make the chocolate flavor pop.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Bake the loaf, cool completely, then wrap tightly in plastic wrap and store at room temperature for up to 3 days. For longer storage, freeze sliced portions in an airtight bag for up to 3 months; toast or warm slices straight from the freezer.
- Can I double the recipe?
- Sure thing. Use two 9×5-inch pans and check earlier (around 50–55 minutes) since smaller loaves or slightly different pan material can change bake times. If you use one large pan, expect longer baking — check with a toothpick.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil.
- How do I know it’s done?
- Look for a top that’s set with a few small cracks, golden edges, and a toothpick with moist crumbs (not wet batter). The loaf should spring back slightly when you press the top.
- What if I don’t have ingredient X?
- No drama. Swap brown sugar with equal granulated sugar plus 1 tbsp molasses (for depth), or skip nuts entirely. Cocoa powder can be reduced to 1/4 cup and balanced with 1/4 cup extra flour for a less intense chocolate profile.
How I Like to Serve It
I slice this warm and spread a little salted butter or cream cheese on top for breakfast with a strong cup of coffee. It also works wonderfully on a dessert plate with vanilla ice cream and a drizzle of chocolate sauce. I bring it to potlucks cut into thick slabs — people always come back for seconds. In fall it feels indulgent by the fire; in summer, it’s great with picnic coffee.
Notes
- Store wrapped at room temperature up to 3 days or freeze slices for up to 3 months. Reheat gently in a toaster or microwave for 10–15 seconds.
