This chocolate chip banana bread is a soft, moist banana loaf loaded with chunks of melting chocolate - the kind of bake that turns those sad, black bananas on your counter into something 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.

- One loaf, one hour Simple to mix, and it freezes beautifully for later.
What Makes It So Good
The magic is in the chocolate itself. Instead of cocoa powder, this loaf leans on generous chunks of chopped chocolate that melt as it bakes, leaving soft, gooey pockets all the way through - far more indulgent than a scatter of tiny chips. Underneath, very ripe bananas and a spoonful of sour cream (or yogurt) keep the crumb tender and moist well past day one, while creamed butter and sugar give it a rich, cake-like softness. Simple ingredients, but the result tastes like a treat.
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 yogurt, 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.

Chocolate Chip Banana Bread
Equipment:
- 9×5-inch loaf pan metal bakes most evenly
- Parchment paper as a sling to lift the loaf out
- Electric mixer for creaming the butter and sugar
- Mixing Bowls one for dry, one for wet
Ingredients:
Dry
- 2 cups all-purpose flour - 250 g
- 1 tsp baking soda
- 1/2 tsp salt
- 1 cup chopped dark or semi-sweet chocolate - 170 g; 3/4 cup for the batter, 1/4 cup for the top
Wet
- 1/2 cup unsalted butter - 113 g, softened
- 3/4 cup granulated sugar - 150 g; or 1/2 cup granulated + 1/4 cup light brown
- 2 large eggs - room temperature
- 1/4 cup sour cream - 60 g; or plain yogurt
- 1 1/2 cups mashed very ripe banana - about 345 g / 3-4 bananas
- 1 tsp vanilla extract
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 3/4 cup 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 1/4 cup 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.

Tips for the Best Chocolate Chip Banana Bread
- The riper the bananas, the better. Spotted-to-black bananas are sweeter and moister. Yellow bananas make a bland, drier loaf.
- Do not over-mix. Stir the batter only until the flour disappears - it should stay thick and a little lumpy. Over-working makes the loaf tough and gummy.
- Toss the chocolate in flour. Coating the chopped chocolate in a little of the flour before folding it in helps stop it sinking to the bottom.
- Tent it with foil. Lay foil loosely over the top around the halfway mark so the loaf can bake through without the top over-browning.
- Read the toothpick carefully. Melting chocolate can look like raw batter - aim between the pieces and look for moist crumbs, not wet streaks.
- Cool before slicing. The loaf keeps cooking as it rests; slicing too early makes the centre seem gummy. Give it an hour.
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.
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.
