Ingredients
Here’s what you’ll need to make this delightful bread:
Basic Banana Bread Batter:
- 3 ripe bananas, mashed (the riper, the better!)
- 2 large eggs
- ½ cup (120ml) melted butter or neutral oil
- ½ cup (120g) granulated sugar
- ¼ cup (60g) brown sugar (for extra depth of flavor)
- 1 teaspoon vanilla extract
- ½ cup (120g) plain Greek yogurt or sour cream (keeps it moist!)
- 1 ¾ cups (220g) all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
Chocolate Swirl:
- ¼ cup (25g) unsweetened cocoa powder
- 2 tablespoons milk (to thin out the batter)
- ¼ cup (45g) chocolate chips (optional but highly recommended!)
How To Make Chocolate Marble Banana Bread

Step 1: Prep Your Ingredients
Start by preheating your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment paper for easy removal.
Mash your bananas in a large bowl until smooth. The riper the bananas, the sweeter and more flavorful your bread will be!
Step 2: Mix the Batter
In the same bowl as the bananas, whisk in the eggs, melted butter, both sugars, vanilla extract, and Greek yogurt. Stir everything until well combined.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add these dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix—this keeps the bread soft and tender!
Step 3: Create the Chocolate Swirl
Scoop out about 1 cup of the batter and place it in a small bowl. Mix in the cocoa powder, milk, and chocolate chips, stirring until well combined.
Step 4: Layer and Swirl
Pour half of the plain banana batter into your prepared loaf pan. Then, add the chocolate batter in dollops on top. Finish with the remaining plain batter.
To create the marbled effect, take a knife or a skewer and gently swirl through the layers. Don’t overdo it—just a few figure-eight motions will give you that beautiful marbled look!
Step 5: Bake to Perfection
Place your loaf in the oven and bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean. If the top starts browning too quickly, loosely cover it with foil.
Once baked, let it cool in the pan for 10–15 minutes before transferring to a wire rack to cool completely.
Pro Tips for the Best Chocolate Marble Banana Bread
- Use overripe bananas – The darker and spottier, the better! They provide natural sweetness and a stronger banana flavor.
- Don’t overmix – Stirring too much can make the bread dense instead of light and fluffy.
- For extra chocolate goodness – Toss in a handful of chocolate chips into the banana batter for even more chocolatey bites.
- Want a healthier version? – Swap half the all-purpose flour with whole wheat flour and reduce the sugar slightly.
- Make it dairy-free – Use coconut oil instead of butter and dairy-free yogurt.
How To Serve Chocolate Marble Banana Bread

- As a breakfast side – Pair it with scrambled eggs or yogurt for a balanced meal.
- Toasted – Pop a slice in the toaster and enjoy a slightly crispy texture.
- With coffee or tea – A perfect afternoon pick-me-up.
