This double chocolate banana bread turns those spotty bananas into something special that walks the line between everyday snack and fancy dessert. It's deep, chocolatey, and super moist - giving you all the homey vibes of regular banana bread but with an extra punch of chocolate goodness you just can't turn down.
I've tested this recipe tons of times and found out that getting your ingredients to the right temp and mixing them just so makes all the difference. The first batch I shared with my buddies left them shocked when I told them it started with old bananas!
Key Ingredients
- Bananas: Need lots of brown spots for best sweetness and moisture
- Unsweetened cocoa powder: Go for quality and freshness - Dutch-process gives the best results
- Room temperature butter: Helps everything blend right - too cool or melty messes up the texture
- Sour cream: Makes it extra tasty and kicks the baking soda into action
- Hot water: Wakes up the cocoa flavor for deeper chocolate taste

Making It Step by Step
- Step 1:
- Get your pan ready first - butter it well and put in parchment paper with extra hanging over the sides so you can lift out the bread easily. Don't skip this or your slices won't come out cleanly.
- Step 2:
- Smash those bananas until they're really smooth. You'll want about 1½ cups from four medium ones. The smoother you make them, the better your bread texture will be.
- Step 3:
- Mix your room temp butter and sugar for a good 3-4 minutes till it's light and fluffy. Take your time here - this step makes your bread turn out just right.
- Step 4:
- Drop in eggs one at a time, mixing well after each. Don't forget to scrape down the sides of the bowl to get everything mixed in.
- Step 5:
- Grab another bowl and sift the flour, cocoa powder, baking soda, and salt together. This gets rid of lumps and makes sure the baking soda spreads out evenly.
- Step 6:
- Add your dry stuff to the wet stuff bit by bit, switching between hot water and sour cream. Just mix till it comes together - too much mixing will make your bread tough.
- Step 7:
- Stir in most of the chocolate chips by hand, but save some to sprinkle on top.
- Step 8:
- Pour the batter into your pan and bake at 350°F for about 60-65 minutes, until a toothpick comes out with just a few moist bits stuck to it.

I got this idea from my grandma's old banana bread recipe but kicked it up with extra chocolate to make it something really worth talking about.
Getting That Fudgy Goodness
After lots of tries, I've learned a few secrets to that perfect texture. You need to measure everything carefully. Mix things in the right order. Bake at just the right heat. And give it enough time to cool down.
Watching The Heat
There are four key temp moments to watch for: Eggs and butter need to be sitting out before you start. Water should be hot but not bubbling for the cocoa. Your oven must be fully heated before the pan goes in. The bread needs to cool all the way before slicing.
Fixing Common Problems
Here's how to handle baking hiccups: If it's too heavy, your baking soda might be old. If the middle sinks, you probably opened the oven too soon. If the chocolate chips all sink, coat them with flour first. If it sticks to the pan, use a parchment paper sling next time.
Try These Twists
Want to change it up a bit? Add some espresso powder for extra depth. Try swirling in some tahini or almond butter. Throw in some toasted walnuts. Or mix in some orange zest for brightness.
Keeping It Fresh
To make it last: Let it cool completely first. Wrap in plastic then foil if you're freezing it. Put wax paper between slices when storing. Let it come to room temp before eating.
I've made this bread so many times now and love how it fits any situation. It's great with morning coffee, as an afternoon pick-me-up, or warmed up with ice cream for a fancy dessert. It just works for everything.
More Ways To Use This Batter
This isn't just for loaf pans. I've tried it as: Small loaves to give as gifts. Muffins to grab and go. A pretty bundt cake. Even as layers in a celebration cake.
Dressing It Up

Make it look fancy with: A drizzle of melted chocolate. Some fresh strawberries or raspberries. A dollop of whipped mascarpone. Sprinkled toasted coconut. A few candied pecans.
Hot, Cold, Or In Between
Try serving it at different temps for new experiences: Room temperature is perfect for breakfast. Slightly warm makes it more dessert-like. Chilled gives you a denser bite. Toasted with a pat of butter is amazing.
Using Up Leftovers
If you somehow don't finish it all: Turn it into bread pudding. Layer it in a trifle. Make the best French toast ever. Create ice cream sandwiches.
After baking this countless times for so many happy eaters, I now think of this double chocolate banana bread as more than just food. It's a way to be creative and make memories. Whether you're whipping it up for a birthday or just using up those bananas before they go bad, each loaf brings both comfort and a bit of celebration to the table.
