Here are the ingredients needed to make this marbled chocolate banana bread.

Ingredient Notes

Bananas - The riper the better for banana bread! You will need 2 cups of mashed bananas which is about 4 bananas worth.
Oil - Any neutral-flavored liquid cooking oil, such as avocado oil, olive oil, or vegetable oil.
Cocoa Powder - For a deep smooth chocolate flavor, I recommend using Dutch-processed cocoa powder.
Chocolate Chips - I use semisweet chocolate chips but you could use any kind of chocolate you prefer!

📃 Instructions

Step 1: Whisk together the oil, brown sugar, eggs, vanilla, and mashed banana until smooth.

Step 2: Whisk together the flour, baking soda, and salt.

Dry ingredients and chocolate chips added to bowl of combined wet ingredients.

Step 3: Add the combined dry ingredients and chocolate chips to the bowl of wet ingredients and mix just until incorporated. Do not overmix!

One bowl with chocolate banana bread batter and one bowl with regular batter.

Step 4: Transfer about 1 ½ cups of the batter to a separate bowl and stir in the cocoa powder just until combined.

Banana bread batter swirl into a pattern in a loaf pan lined with parchment paper.

Step 5: Layer scoops of the batter into a prepared loaf pan. Finish by swirling a knife through a few times to create a marbled look.

Step 6: Bake in a preheated oven for 60-70 minutes or until a tester inserted into the center comes out clean.

Let the banana bread cool in the pan for 10 minutes before transferring to a wire rack to finish cooling before slicing.

💡 Top Tips

It is super important to not overmix the batter when making banana bread! A good rule of thumb is to mix just until no streaks of flour remain, then stop mixing and pour the batter into the pan. Overmixing may result in a tough loaf or even cause a gummy layer of glutenous batter to settle to the bottom of the loaf.

Baking time for this recipe and others usually depends on a few factors. Everyone's oven is different, so your banana bread may take a shorter or longer time than what I put in the recipe. For this particular recipe, I'd recommend checking your banana bread 10-15 minutes before the timer goes off. It probably won't be done yet, but it's nice to see how it's coming along

Another factor when it comes to baking time is what kind of pan you are using. Metal pans tend to bake faster a brown quicker around the edges than a glass pan would. I use a metal bread pan for this recipe so be prepared to have to bake the bread for a bit longer if using a glass pan.
