Here is a delicious, one-bowl healthy chocolate banana cake recipe you can whip up any time you’re craving rich and decadent chocolate cake!
Healthy chocolate banana cake
This lightened up chocolate cake is made with just 8 ingredients.
And it’s the perfect healthy snack or dessert, with a full third cup less sugar than traditional chocolate cake recipes of the same size.
The chocolate banana cake is packed with whole grains and nutrition and can be oil free, dairy free, gluten free, egg free, and vegan.
Just one decadent taste, and you’d absolutely never guess the secret!

Ingredients for chocolate banana cake
To make the vegan chocolate banana cake, you will need flour, cocoa powder, baking soda, salt, water, sugar, optional nut butter or oil, pure vanilla extract, and banana.
Flour – Spelt flour, white flour, oat flour, and many brands of all purpose gluten free flour will work. If you prefer a cake with almond flour, try this Keto Cake.
I have not tried whole wheat flour here and recommend against coconut flour because it can not be substituted equally without making other adjustments to the recipe.
Cocoa powder – The recipe calls for one fourth cup of regular unsweetened cocoa powder plus an additional two tablespoons of Dutch cocoa powder or additional unsweetened cocoa.
Look for Dutch cocoa in the baking aisle of traditional grocery stores or specialty cake supply stores. It will give the cake a deep chocolate brownie flavor.
Sweetener – This can be classic white sugar, or xylitol for an added sugar free chocolate banana cake. You may also use an equal amount of coconut sugar, date sugar, or unrefined cane sugar.
I cannot vouch for substituting pure maple syrup, honey, or agave, as I have not tried liquid sweeteners in the recipe.
Oil – I love the texture of this dessert with coconut oil or softened almond butter.
Vegetable oil is a good choice as well, or you can create a healthy fat free chocolate cake by substituting additional mashed banana for the oil.

How to make a banana chocolate cake recipe
The best part about this cake is how easy it is to throw together.
You simply mix the ingredients in a bowl, pour the batter into a pan, and sit back while it magically turns into a sweet and deliciously rich chocolate cake.
- To make the recipe, start by preheating the oven to 350 degrees Fahrenheit. Line an eight inch baking pan with parchment paper or grease the bottom of the pan.
- In a large mixing bowl, combine all dry ingredients. Stir very well, then evenly mix in the remaining ingredients to form a chocolate cake batter.
- Pour the thick chocolate batter into the prepared pan. If desired, sprinkle mini chocolate chips or finely chopped walnuts or pecans on top.
- Place the pan on the center rack of the oven, and bake for 25 minutes.
- Use potholders to remove the pan, and let it cool on the counter.
- Cover the homemade chocolate banana cake with a towel and let it sit overnight, either on the countertop or in the refrigerator.
It’s important to only cover the with a towel instead of in an airtight container for the first night, because this allows excess moisture to escape and prevent the chocolate banana dessert from becoming dense and soggy.
If you can wait, both the texture and the rich chocolate flavor are even better a day after you make the cake.
The recipe was adapted from my Vegan Banana Cake and Vegan Chocolate Cake.
Ideas for serving the banana dessert
After school snacks will never be the same again.
This healthy snack cake is good plain or topped with Coconut Whipped Cream.
Or top it with fresh strawberries, raspberries, blueberries, and sliced bananas. Add a quick drizzle of chocolate syrup or a sprinkle of powdered sugar.
It’s also wonderful frosted with Coconut Butter or Homemade Nutella.
If you somehow find yourself with leftovers (and this is a big if!), slice and freeze leftover cake for a rainy day. Or a snowy day, a sunny day, or any day.
After all, do you really need an excuse to eat more chocolate cake in your life?

My word! All your recipes ideas are crazy good! Made this for our 21st anniversary! Just a note that I had t to bake this recipe longer by an additional 25 minutes in a conventional oven.
This is so yummy and we ate it the same day I made it. It’s so moist and has the perfect amount of sweetness. I found it took about 40 minutes to bake in the oven though.
Super recipe. A few adjustments if you like- I am trying to stay away from sugar. I replaced the sugar as follows: I took 2/3 cups of pitted dates. About 1/2 cup of boiling water poured over the dates in a food processor. Leave about 10 minutes. Then purée. I added a little less water than as directed since the date purée is soft. I mixed all wet ingredients in food processor and slowly added the dry ingredients and mixed. Added the after until it had a good pourable consistency. I did 1/2 extra PB and 1/2 extra nut butter *of the 1/3 cup. Delicious!
SO GOOOD! And I am eating this like 1 hour later. Hope it makes it until tomorrow. I’ve always wanted to try one of your recipes Katie! Finally did and it did not disappoint
I did add 1/2 a tsp baking powder. Besides that I followed the recipe and used oil instead of nut butter or extra banana.
Thank you so much for making it!
I did this one with almond butter and it came out great. In my case, I left it rest until the next day and there were some sections at the buttom that were not completely done and I loved that because it gave the cake some fudgy vibe!! I have tried several cake recipes from Katie but this one is the one I liked the most because is very easy and it can be done without oil. Next time I will add it some chocolate protein powder.
Can I add more banana instead of sugar? Would i need to reduce the oil quantity if I substitute sugar with banana?
it was amazing. I can’t believe a healthy cake can be this much delicious.
I just used buttermilk instead of water and add 1 tablespoon of instant coffee with brown suger for extra flavour. My husband loved it. Thank you so much for the great recipe
Has anyone ever added a pureed cooked beet to the cake? LOVE this recipe!
Absolutely addicted! This recipe comes out perfect every time!
Delicious and easy! I’m a registered dietitian and was doing a zoom cooking demo and used this recipe (giving you full credit for recipe of course) and it was so easy to make and my family LOVED eating afterwards. I must say, I dug in when it was still slightly warm and it was awesome! I still haven’t gotten to try it the next day yet, will do when I get home. Thank you
Thank you so much!!
