Baking Great Bread at HomeReal Banana Bread That Drinks Like a Brownie
BeginnerChocolate BananaBread
by Henry Hunter Jr.
Deep, fudgy, and built on the banana bread you already trust. Cocoa and a quiet hit of espresso make the chocolate taste like chocolate.
Bake Time
55-65 minutes
Yield
1 loaf (10-12 slices)

Authentic Flavor
This is what happens when honest meets a brownie. You start with the same moist, sour-cream base, then swap a little of the flour for cocoa powder so the batter stays tender instead of turning dry and heavy. A spoonful of espresso powder does the real work behind the scenes. You won't taste coffee. You'll just taste more chocolate. Fold in a handful of chips and you've got a loaf that's hard to leave alone while it's warm.

Prep Work
Getting organized before you start makes everything go smoother. Chocolate batters move fast once the cocoa hits the wet, so set yourself up first.

Preheat oven
Set your oven to 350°F (175°C). Position a rack in the lower third of the oven. This keeps the top from setting before the center catches up.
Prepare the loaf pan
Grease a 9x5 inch loaf pan with butter or non-stick spray. Line the bottom and long sides with a strip of parchment, leaving an overhang on both sides like handles. Dark batters can stick, so don't skip this.
Bring ingredients to room temperature
Set out the butter, eggs, sour cream, and milk. Room temperature ingredients blend smoothly and trap more air when you cream the butter.
Pro Tip
If your bananas aren't ripe enough, you can speed things up. Place unpeeled bananas on a baking sheet and bake at 300°F for 15-20 minutes until the skins are black and the fruit is soft. Cool before using.
Dry Mix
Mix the Dry Ingredients
Cocoa clumps. A good whisk now saves you from chasing dry pockets later.

Sift if lumpy
If your cocoa powder is clumpy, sift it before measuring or push it through a fine mesh strainer into the bowl. Smooth cocoa means smooth crumb.
Combine dry ingredients
In a medium bowl, whisk together the flour, cocoa powder, espresso powder, baking soda, salt, and cinnamon until the color is even with no streaks of pale flour.
Set aside
Keep this bowl ready to add to the wet mixture later.
Pro Tip
Use the method for both the flour and the cocoa. Fluff, spoon into the cup, then level with a flat edge. Scooping packs in extra and dries out the loaf, and that matters even more now that you've already cut the flour to make room for cocoa.
Mash
Mash the Bananas
The riper the better. Black and ugly bananas are exactly what you want here.

Peel and mash
Peel the bananas into a bowl. Using a fork or potato masher, mash until mostly smooth with a few small chunks left for texture.
Measure if needed
You should have about 1½ cups of mashed banana. A little more or less is fine.
Pro Tip
Cocoa mutes sweetness, so really ripe bananas pull double duty here, bringing both flavor and natural sugar.
Cream
Cream the Butter and Sugar
This step builds the structure that keeps a chocolate quick bread from baking up like a dense brick.

Beat butter and sugar
In a large bowl with a hand mixer, or a stand mixer with the paddle, beat the softened butter and brown sugar on medium-high until light and fluffy, about 3 minutes. It should look noticeably lighter in color.
Add eggs
Add the eggs one at a time, beating well after each. Scrape down the sides of the bowl as needed.
Add sour cream, milk, and vanilla
Beat in the sour cream, milk, and vanilla until combined. The milk gives the cocoa something extra to drink so the loaf stays moist.
Add mashed bananas
Mix in the mashed bananas on low until just combined. The mixture may look a little curdled. That's normal and it comes together once the dry goes in.
Pro Tip
Don't rush the creaming. Those 3 minutes of beating create the air pockets that make the difference between tender bread and a heavy one, and cocoa makes a heavy loaf even heavier.
Combine
Combine Wet and Dry
Gentle hands from here on. Overmixing is the fastest way to a tough, gummy loaf.

Add dry to wet
Add the cocoa-flour mixture to the banana mixture all at once.
Fold gently
Using a rubber spatula, fold the dry into the wet with broad, gentle strokes. Scrape the bottom and sides of the bowl. The batter will be thick, dark, and almost mousse-like.
Stop when just combined
Mix only until you no longer see dry cocoa or flour. A few small lumps are fine. Do not overmix.
Fold in the chips
Add the chocolate chips, and the nuts if using, and fold them in with 2 or 3 more strokes. Hold back a small handful of chips to press into the top if you want them showing.
Pro Tip
Count your folds if it helps. You should need no more than 15 to 20 total. The batter should look rough and thick, not smooth and pourable like cake batter.
Shaping
Pan Options
This batter works in several pan sizes. The chips and cocoa hold moisture, so smaller pans need a careful center check.
Standard 9x5 Loaf
RecommendedClick each step to mark complete
Pour batter
Pour batter into greased 9x5 loaf pan. Smooth top with spatula.
Bake
Bake 55-65 minutes at 350°F.
8x4 Loaf Pan

Pour batter
Pour batter into smaller 8x4 loaf pan. Batter will mound higher in the pan.
Increase bake time
Increase baking time to 60-70 minutes. Check center carefully, smaller pans can trap moisture.
Mini Loaves

Divide batter
Divide batter among 3-4 mini loaf pans (5x3 inch). Fill each about ⅔ full.
Reduce bake time
Reduce baking time to 35-45 minutes. Great for gifting!
Muffins
Click each step to mark complete
Fill muffin cups
Line standard muffin tin with paper liners. Fill cups about ¾ full.
Bake
Bake 20-25 minutes at 350°F. Makes about 12 muffins.
Proof Test: Insert a toothpick into the center. It should come out clean or with just a few moist crumbs. Wet batter means it needs more time. A completely clean toothpick on first check might mean it's slightly overbaked.
Bake
Bake
A dark loaf hides its color cues, so lean on the toothpick and the clock instead of your eyes.
Step by Step
Fill the pan
Scrape the batter into the prepared pan. Smooth the top with a spatula and press in any reserved chips.
Optional topping
For crunch and a little shine, sprinkle a tablespoon of raw sugar or extra chips across the top before baking.
Set your oven
Confirm the oven is at 350°F (175°C) with the rack in the lower third.
Bake undisturbed
Bake for 55-65 minutes. Don't open the door for the first 45 minutes. Chocolate batters need that steady heat to set.
Check for doneness
Start checking at 55 minutes. A toothpick in the center should come out with a few moist crumbs and no wet batter. Melted chips can fake you out, so test in a spot between chips. Internal temperature should read 200-205°F (93-96°C).
Tent if needed
Cocoa browns fast. If the top is darkening before the center is set, tent loosely with foil for the last 15-20 minutes.
Quick breads crack on top, and that's a good sign of oven spring. With a dark loaf the crack should look fudgy and moist inside, not wet or raw.
Baking Methods
Equipment: 9x5 loaf pan, Rack in lower third position
Preheat oven
Preheat oven to 350°F.
Position rack
Position rack in lower third of oven.
Bake
Bake 55-65 minutes. Tent with foil if browning too fast.
Test for doneness
Test with toothpick for doneness.
Cool
Cool and Serve
Patience pays off. Cutting too soon gives you a gummy slice and lets the chips run.

Initial cooling
Let the bread cool in the pan on a wire rack for 15 minutes so the structure can set.
Remove from pan
Using the parchment handles, or by running a knife around the edges, lift the loaf out onto the wire rack.
Cool completely
Let it cool another 30-45 minutes before slicing. A warm chocolate loaf will smear instead of slice clean.
Slice and serve
Use a serrated knife for clean slices. Good plain, even better slightly warm with a little butter, and best the next day.
Pro Tip
Chocolate banana bread tastes even deeper on day two. The cocoa rounds out and the banana settles in. Wrap it well overnight and you'll see.

Storage
Room Temperature
Wrap tightly in plastic wrap or store in an airtight container at room temperature for up to 4 days. The bread actually tastes better on day 2 once the flavors have melded.
Refrigerated
Not recommended. Refrigeration accelerates staling.
Frozen
Wrap the whole loaf tightly in plastic wrap, then aluminum foil, then place in a freezer bag. Freeze for up to 3 months. You can also freeze individual slices for quick grab-and-go portions. Thaw overnight at room temperature or toast slices directly from frozen.
Refresh
Toast slices directly from frozen, or warm a whole loaf at 350°F (175°C) for 10-12 minutes.
