Visually pretty chocolate marble banana bread that is the perfect weekend baking project.

Banana bread is an easy go-to when you have lots of bananas and are craving a sweet dessert!

It’s also perfect for feeding a crowd. Impress your guests and make it marble. It will look and taste amazing.

This banana bread is “accidentally vegan.” I don’t love wasting eggs and only have nut milks in the fridge, though any milk will work.

So yes, this recipe is dairy free, egg-free and vegan!

About The Bananas

If your bananas are not covered in brown spots they are not fully ripe and sweet enough.

You can stick your unripe, yellow bananas (with the peel on) on a baking sheet while the oven preheats to 350°F.

This will turn the bananas soft and sweet. The skins will turn black. Do not leave the bananas in the oven more than 10 minutes.


Mix Dry Ingredients

First, preheat your oven to 350°F.

In a large bowl, combine the flour, sugar, baking powder, baking soda, and salt. Whisk well then set aside.


Mix Wet Ingredients

Using a fork, mash two large bananas well then add them to a second bowl.

Add the milk, oil, and vanilla and whisk well.


Add Wet To Dry

Add your wet mixture to the dry and using a spatula, mix until all of the dry bits have been absorbed.


Make Chocolate Paste

In a third bowl, combine the cocoa powder and 7 tbsp of hot water. Mix until it becomes a paste.

Set aside.


Divide The Batter

Add about half of the banana bread batter to the chocolate paste and mix well.


Scoop & Bake

Grab your loaf tin and line with parchment paper and/or grease lightly with oil.

I like to grease the sides a bit and line the tin horizontally with some parchment paper overhang for easy removal (see image).

Using an ice cream scoop or 1/4 measuring cup, scoop the vanilla and chocolate batter into the loaf tin alternating between the two batters to create a marble effect.

Once all of the batter is in the loaf tin, use a butter knife to lightly swirl the batter to enhance the marble effect even more.

Top the batter with two bananas halves, if desired.

Bake the banana bread at 350°F for 45-55 minutes or until a toothpick inserted in the middle comes out clean/with some dry crumbs left.


Allow to Cool & Serve

After the banana bread is done baking, allow it to cool in the tin for about 10 minutes before removing.
