Ingredients and Variations
Bananas - Use over-ripe bananas- the darker the better for this recipe! You will need 3 medium-large bananas or 4 smaller ones.
Sugar - Use granulated or light brown sugar (or a mixture of both). For this recipe, I prefer using brown sugar for a fudgier consistency, but both types will work fine!
Egg - for binding the cake
Flour - Use all-purpose or cake (preferred) flour. I suggest using a digital kitchen scales to accurately measure your ingredients.
Cocoa powder - I used unsweetened cocoa powder.
Cinnamon - this is optional. Eliminate if you're not a cinnamon fan
Baking soda - leavening agent
Salt - flavor enhancer
Butter - use melted unsalted butter
How to Make Chocolate Banana Marble Loaf Cake
- Mash bananas using a fork or potato masher and set aside.
- Sift and mix dry ingredients except cocoa powder and set aside.
- Mix melted butter and sugar. Use a stand mixer fitted with the paddle attachment or a handheld mixer.
- Add the egg and mashed ripe bananas and beat well.
- Add dry ingredients slowly and mix until just combined.
- Transfer approximately ⅓ (more or less as desired) of the batter to a separate bowl and fold in sifted cocoa powder. Use a spatula to mix until batter turns brown.
- Spoon the plain and chocolate batters in an alternate fashion in an 8x4" loaf pan and using a skewer or chopstick, swirl the mixtures around.
- Bake in a preheated oven at 350F for 45-55 minutes until a skewer inserted into the center comes out clean.
- Cool in loaf pan, transfer to a cooling rack to cool completely, and serve!

- Add the egg and mashed bananas. Mix on medium speed for 1-2 minutes.
- Slowly add dry ingredients and mix on slow speed until just incorporated. Do not over-mix!
- Transfer ¼ to ⅓ of the batter (depending on your preferences) to a separate bowl and fold in sifted cocoa powder. Mix using a spatula until combined.
- Spoon the plain and chocolate batters in an alternate fashion in the loaf tin and using a skewer or chopstick, swirl the mixtures around.

Notes
- You may freeze banana bread once it has cooled completely for up to 2 months.
- The batter can be split in whichever way you want. If you would like the bread to be less chocolatey, split the batter into ¼ and ¾ parts. Decrease the amount of cocoa powder, and add this to your ¼ part batter. If you'd like a more chocolatey cake, split the batter into to approximately equal halves (and add cocoa to one part only).
