Those sad black bananas on the counter are the whole point of this loaf: a soft, moist chocolate chip banana bread loaded with chunks of melting chocolate, the kind everyone fights over. There is no cocoa here; all the chocolate comes from generous pieces of chopped chocolate folded right through the batter, so every slice has warm, gooey pockets running through it. It is a one-loaf, no-fuss recipe, and it is even better on the second day.
Pin itWhy You Will Love This Chocolate Chip Banana Bread
- Moist and tender Ripe banana plus a little sour cream keeps it soft for days.
- Loaded with chocolate Chunks of dark chocolate melt into gooey pockets in every slice.
- Uses up black bananas The riper and uglier they are, the better this loaf tastes.
- One loaf, one hour Simple to mix, and it freezes beautifully for later.
Pin itA Closer Look at the Ingredients
- Very ripe bananas The star. Use heavily spotted or black bananas - their starch has turned to sugar, so the loaf is sweeter and moister.
- Chopped chocolate Dark or semi-sweet, chopped into chunks so it melts into gooey pockets. Most goes in the batter, a little on top.
- Butter and sugar Creamed together for a rich, cake-like crumb.
- Sour cream A little goes a long way for a soft, moist loaf that keeps.
- Flour, baking soda and eggs The simple base that holds it all together and gives a good rise.
Ingredient Substitutions
- Butter to oil: swap the creamed butter for the same amount of neutral oil (or melted butter) for an even moister, denser loaf - you lose a little flavour but gain softness.
- Sour cream: plain or Greek yoghurt, or buttermilk, all work in its place (add a spoon more flour if using buttermilk, as it is thinner).
- Sugar: all granulated is fine, or replace a quarter with light brown sugar for a caramel note and extra moisture.
- Chocolate: chopped bar chocolate gives the meltiest pockets, but chocolate chips work too. Dark, milk, or a mix all suit banana - or add a handful of nuts.
- Gluten-free: a good 1-to-1 gluten-free baking blend works; expect a slightly denser, more tender crumb.
Equipment You Will Need
- A 9×5-inch loaf pan The right size for this thick batter - a smaller 8×4 bakes unevenly with a raw middle.
- Parchment paper A sling with an overhang lifts the whole loaf out cleanly.
- An electric mixer For creaming the butter and sugar (a fork works for a melted-butter version).
- A cooling rack So the loaf cools evenly before slicing.
Pin itHow to Make Chocolate Chip Banana Bread, Step by Step
The card below has the quantities. This is the same eight steps with the reasoning attached, including the two that decide how the loaf turns out: how long you beat it, and how long you leave it alone afterwards.
- Heat the oven to 175°C, 350°F, grease a 9×5 inch loaf tin and line it with parchment, leaving an overhang at the long sides. That overhang is a sling: banana bread is soft and heavy when it comes out and tipping it from a bare tin is how the top gets left behind.
- Whisk the flour, baking soda and salt together, then stir in three quarters of the chopped chocolate so every piece is dusted in flour. That dusting is the whole trick for stopping it sinking. Bare chocolate slides through a wet batter as it loosens in the oven and ends up in a seam along the bottom; a floury coating gives the batter something to grip.
- Beat the softened butter and sugar on high for about three minutes, until it is noticeably paler and looks creamy rather than grainy. You are not just combining them here, you are working air into the butter, and that air is a good part of what gives this loaf its light, cake-like crumb rather than the denser texture of a melted-butter version. Softened means it gives under a finger and no more, because butter that has gone greasy will not hold the air.
- Beat in the eggs one at a time, then the soured cream, mashed banana and vanilla, and stop as soon as it comes together. It will look slightly split and curdled at this point, which is normal and comes right when the flour goes in.
- Add the dry mixture and mix on the lowest speed only until the flour disappears. The batter should stay thick and a little lumpy, and lumpy is the finished state, not a stage on the way to smooth. Every extra turn develops the gluten in the flour, which is exactly what you want in a yeasted loaf and exactly what you do not want here: it makes the crumb tough, and it goes stretchy enough to trap the rising gas in big pockets, so you get coarse tunnels running through the slice. If your loaf has ever come out with holes like that, this step is where it happened.
- Scrape the batter into the tin and level the top, then scatter the reserved quarter of the chocolate down the centre. Down the centre rather than all over: that is where the loaf splits as it rises, so the chocolate ends up in the crack rather than burning on the crust.
- Bake for 60 to 65 minutes, tenting loosely with foil at about 30 to 35 minutes so the top stops browning while the middle catches up. Start checking at 55. The toothpick test is genuinely harder in this loaf than in a plain one, because a melted chocolate chunk looks exactly like raw batter, so aim between the pieces and look for a few moist crumbs rather than wet streaks.
- Cool in the tin on a rack for at least an hour before you lift it out and slice it. This is not patience for its own sake: the middle carries on cooking in the residual heat after it leaves the oven, and a loaf cut at twenty minutes will seem gummy in the centre when it is simply not finished. It is better again on the second day.

Chocolate Chip Banana Bread
A soft, moist banana bread loaded with chunks of melting chocolate. Made with very ripe bananas and chopped dark chocolate folded right through - one easy loaf, and even better on the second day.
Equipment I Use
Ingredients
Instructions
Heat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment, leaving an overhang to lift the loaf out later.
Whisk the flour, baking soda and salt in a bowl. Stir in the 130 g of chopped chocolate - tossing it in the flour helps stop it sinking to the bottom.
Beat the softened butter and sugar on high for about 3 minutes, until pale and creamy.
Beat in the eggs one at a time, then the sour cream, mashed banana and vanilla until just combined.
Add the dry mixture and mix on low just until combined. The batter is thick - do not over-mix, or the loaf turns tough and gummy.
Scrape the batter into the pan and level it. Scatter the reserved 40 g of chopped chocolate down the centre.
Bake for 60-65 minutes. Tent loosely with foil at about 30-35 minutes so the top does not over-brown. It is done when a toothpick in the centre (between the chocolate) comes out with a few moist crumbs, not wet batter - start checking at 55 minutes.
Cool in the pan on a rack for at least 1 hour before lifting the loaf out and slicing. It keeps cooking as it rests, so slicing too early makes the centre seem gummy.
Chef’s notes
Riper is better: use heavily spotted or black bananas - sweeter, moister loaf. Yellow bananas make it bland and dry.
Do not over-mix: stop as soon as the flour disappears; a thick, slightly lumpy batter bakes tender, not tough.
Toss the chocolate in flour before folding it in so it stays suspended instead of sinking.
Chopped bar chocolate gives melty pockets; chocolate chips work too, and dark, milk or a mix all suit banana.
Read the toothpick carefully: melting chocolate can look like raw batter - aim between the pieces and look for moist crumbs.
Cool fully before slicing for clean, moist slices.

Variations
- Chocolate banana muffins. Divide the batter into a lined muffin tin and bake at 350°F (175°C) for 18-25 minutes. Makes about 12-16.
- Lighter loaf. Use melted butter and one egg instead of the creamed method for a quicker, one-bowl version; a pinch of cinnamon is lovely here.
- Extra indulgent. Drizzle the cooled loaf with melted chocolate, or add a handful of chopped walnuts to the batter.
- Peanut butter swirl. Dot spoonfuls of peanut butter over the batter and swirl through with a knife before baking. For more of a treat, try it next to my banana and date brownies.
What to Serve With Chocolate Chip Banana Bread
This loaf is gorgeous just as it is, still slightly warm with the chocolate soft, but a few finishes make it feel like pudding. Melt a pat of salted butter into a warm slice, serve it à la mode with a scoop of vanilla ice cream, or spread it with peanut butter for a chocolate-and-PB hit. A strong coffee or a cold glass of milk is the perfect partner. If you are in a chocolate mood, follow it another day with my ultimate gooey chocolate brownies.
FAQ for Chocolate Chip Banana Bread
My bananas are almost black - are they still okay to use?
Yes, black and mushy is exactly what you want - they are the sweetest and give the moistest crumb. Only throw them out if they smell fermented or alcoholic, or show any mould.
Can I use frozen bananas?
Yes. Thaw them fully, then drain off the watery liquid before mashing and measuring, so the batter does not turn out too loose.
Why did mine come out gummy in the middle?
Almost always underbaking (or misreading the toothpick where melty chocolate looks like raw batter), too much banana, or over-mixing. Bake until the toothpick shows moist crumbs, keep the banana measured, mix minimally, and cool the loaf fully before slicing.
Should I use chopped chocolate or chocolate chips?
Chopped bar chocolate is best here - it melts into bigger, gooey pockets and gives that rich, chocolatey bite. Chocolate chips work too and hold their shape more; use whichever you have, dark or semi-sweet.
Can I make muffins instead of a loaf?
Yes. Fill lined muffin cups near the top and bake at 350°F (175°C) for 18-25 minutes, until a toothpick comes out with moist crumbs. The recipe makes about 12-16 muffins.
How do I store and freeze it?
Wrapped airtight, it keeps 3 to 5 days at room temperature (often best on day two). To freeze, cool completely, double-wrap and freeze the whole loaf, or individual slices, for up to 3 months. Thaw at room temperature.
My bananas are not ripe enough. How do I hurry them up?
Put them in a paper bag with a ripe apple or another ripe banana, and leave them on the worktop for a day or two. Ripe fruit gives off ethylene, which is the gas that drives ripening, and the bag holds it around the bananas instead of letting it drift off. Paper rather than plastic matters: a plastic bag traps the moisture as well and you end up with soggy skins. If you need them the same day, bake unpeeled bananas at 150°C for 15 to 20 minutes until the skins go black. That softens and sweetens them enough to use, though not quite as much as real ripening does, so you may want a spoonful more sugar.
Why does it have to be a very ripe banana?
Because a banana keeps ripening after it is picked, and what it is doing while it sits on your worktop is converting its stored starch back into sugar. A firm yellow banana still has a lot of that starch locked up, so it is less sweet and it mashes into something pasty rather than loose. A heavily spotted or black one has done the work for you: sweeter, softer, and it blends into the batter instead of sitting in it as lumps. This is also why a black banana makes a better loaf than a yellow one plus extra sugar would.
A Few Words from the Chef
There is something very satisfying about turning three sad, black bananas into a loaf this good. This is my answer to a chocolate craving that also uses up what is on the counter - soft, moist, and studded with gooey chocolate, even better on the second day with a coffee. Do not rush the cooling, resist cutting into it too soon, and you will be rewarded with clean, moist slices full of melting chocolate. Honestly, leftover bananas can make a great dessert - and this one is super delicious. Enjoy.
