Ingredients

To make double chocolate chip banana bread from scratch, you’ll need the following ingredients:

I like to use 3-4 medium to large bananas for each batch!
Melted unsalted butter makes the banana bread really easy to mix by hand. No need to whip softened butter!
I like to use a mix of brown sugar and granulated sugar to create the perfect balance of flavor and texture.
- You can use either light or dark brown sugar. Dark brown sugar will just give you a deeper butterscotch flavor.
I like to use Dutch cocoa powder because it’s not as acidic as natural cocoa powder. It’s also darker and richer in flavor.
Buttermilk yields a soft, moist banana bread, with a slight tang!
For a satisfying sweet crunch, I like to sprinkle the loaf pan and the top of the banana bread with turbinado sugar right before baking.
You can use either vanilla extract or vanilla paste (1:1) in this recipe.
If you want to amplify the chocolate flavor even more, add in a bit of espresso powder (not pictured)!

💡 Baking Tip

Weigh your ingredients! One of my favorite kitchen tools is a kitchen scale because it’s more accurate than measuring by volume. If you use cups, spoon the flour in gently, then level it with a knife or a spatula.

How to Make Double Chocolate Chip Banana Bread

Step 1: In a large mixing bowl, mix melted butter and cup cocoa powder. Mix in sugars until well combined.

Step 2: Whisk in eggs until completely smooth.

Step 3: Stir in mashed bananas, buttermilk, vanilla, and chocolate chips until combined.

Step 4: Stir in dry ingredients, then transfer into loaf pan(s). Optionally sprinkle on turbinado sugar and chocolate chips. Bake for 1 hour, or until top is set and a toothpick/cake tester comes out mostly clean with a few crumbs. Cool in pan for 5 minutes. Remove and let completely cool on wire rack before slicing. Enjoy!

Storage

Room temperature: Store fully cooled double chocolate chip banana bread in an airtight container at room temperature for up to 5 days.
Freezing instructions: I personally like to batch make double chocolate chip banana bread and freeze them so I can eat them whenever I want!
- Whole loaf: Wrap the entire loaf in aluminum foil, then store in a freezer bag. Thaw at room temperature, about 4-5 hours.
- Slices: Layer slices in an airtight container with squares of parchment or wax paper in between, so they don’t stick and freeze together. Thaw at room temperature, about 30 minutes. I personally like to reheat the slices in a microwave or toaster oven!
