This double chocolate banana bread takes those spotty bananas and turns them into something truly special - a treat that feels like both a casual snack and a fancy dessert. It's super chocolatey, wonderfully moist, and brings together that comforting banana bread feeling with an extra hit of chocolate goodness you won't be able to walk away from.
I've made this bread tons of times to get it just right. The secret's all about ingredient temps and how you mix everything together. The first batch I shared with my buddies left them shocked when I told them I started with old bananas!
Key Components
- Bananas: They need those brown spots all over - that's when they're sweetest and juiciest
- Unsweetened cocoa powder: Go for quality and freshness - Dutch-process gives the best results
- Room temperature butter: This helps everything mix properly - too cold or melty and your texture suffers
- Sour cream: Adds a lovely richness and helps the baking soda do its job
- Hot water: Wakes up the cocoa flavor for a deeper chocolate taste

Baking Guide
- Step 1:
- Start by getting your pan ready - butter it well and add parchment with extra hanging over the sides. This makes taking the bread out super easy later.
- Step 2:
- Squish your bananas until they're completely smooth. You'll want about 1½ cups from four medium bananas. The smoother they are, the better your bread texture will be.
- Step 3:
- Mix your softened butter and sugar together until it's pale and fluffy, taking about 3-4 minutes. Don't cut this short - it's what gives your bread that perfect texture.
- Step 4:
- Put in eggs one by one, mixing well after each. Keep scraping down the sides to make sure everything mixes evenly.
- Step 5:
- In another bowl, mix flour, cocoa powder, baking soda, and salt through a sifter. This gets rid of lumps and makes sure the rising agent spreads out nicely.
- Step 6:
- Add your dry stuff to the wet stuff bit by bit, switching between adding hot water and sour cream. Mix just enough to combine - too much mixing will make tough bread.
- Step 7:
- Stir in chocolate chips with a spoon, but save some to sprinkle on top.
- Step 8:
- Pour the batter into your pan and bake at 350°F for 60-65 minutes, until a toothpick comes out with just a little bit of moisture.

I got the idea for this from my grandma's old banana bread recipe, but added loads of chocolate to make it extra special.
Achieving Wonderful Texture
After many tries, I found that getting that fudgy texture comes down to a few things: Measuring everything correctly. Mixing in the right order. Baking at the right heat. Giving it enough time to cool.
Watching The Heat
Pay attention to temperature at these points: Eggs and butter at room temp. Water that's hot but not bubbling. Oven heated up beforehand. Letting it cool fully before slicing.
Fixing Common Problems
Quick answers for baking troubles: Too heavy? Check if your baking soda is fresh. Middle sinking? Keep the oven door closed. Chocolate chips all at bottom? Coat them in flour first. Stuck in the pan? Use a parchment paper sling.
Fun Twists To Try
While keeping the basic idea: Mix in some espresso powder for deeper flavor. Add swirls of tahini or almond butter. Throw in some toasted walnuts. Grate in some orange peel.
Keeping It Fresh
To make it last longer: Let it cool all the way first. Wrap in plastic then foil before freezing. Put wax paper between slices. Warm up to room temp before eating.
I've made this bread countless times, and what I love most is how flexible it is. It's great in the morning with coffee, as a snack during the day, or heated up with some ice cream for dessert - it fits any situation perfectly.
More Ways To Use This Recipe
I've found you can do so much more than just make a loaf: Small loaves make great gifts. Turn the batter into muffins. Bake it in a bundt pan. Even try it as a layer cake.
Beautiful Presentation Ideas

Make it look extra fancy with: Melted chocolate drizzled on top. A handful of fresh berries. A dollop of whipped mascarpone. Some toasted coconut flakes. A sprinkle of candied pecans.
Try It At Different Temperatures
The taste changes depending on how you serve it: Room temperature works great for breakfast. Slightly warmed makes a cozy dessert. Chilled gives a denser bite. Toasted slices taste amazing with butter.
Using Up Leftovers
When you have extra slices: Make bread pudding. Layer in a trifle. Use for amazing french toast. Create ice cream sandwiches.
After baking this bread more times than I can count and seeing so many happy faces, I've realized this double chocolate banana bread is more than just food - it's a way to get creative and make memories. Whether you're whipping it up for a birthday or just using bananas that would go bad, each loaf brings both comfort and a little celebration to your day.
