Introduction
Do you like cakes made with vegetable oil instead of butter?
If you do, this simple and easy cake is for you!
It becomes the perfect snacking cake or everyday dessert with its rich chocolate flavor with just a hint of banana flavor. Garnishing this cake with a chocolate ganache frosting transforms it into a decadent dessert for those extra special occasions.
As a bonus, it requires no fancy equipment and comes together in no time at all. All you need to make this simple cake are a couple of bowls, a whisk and a mixing spoon.
Garnish it with a dusting of icing sugar or if you prefer, bring it to the next level by topping it with a chocolate ganache frosting as we did today. Either way, it’s delicious!
Directions
Preheat the oven to 350℉ (175°C). Position the rack in the center of the oven.
Grease and dust a 9 x 13-inch baking pan with cocoa powder (or use non-stick spray) -set aside for now.
In a large mixing bowl, sift or whisk together the dry ingredients. More specifically, 1¾ cups of all-purpose flour (250 grams), 1¼ cups of granulated sugar (250 grams), ¾ cup of unsweetened cocoa powder (65 grams), 1½ teaspoons of baking powder, 1½ teaspoons of baking soda and ½ teaspoon of salt. Set aside for now.
In a medium bowl, whisk together 2 eggs (room temperature) with ½ cup of vegetable oil, ½ cup of milk (room temperature), ½ cup of warm coffee, ½ cup of warm water and 1½ teaspoons of pure vanilla extract. Add 1 cup of mashed bananas. Whisk to combine properly together.
Add wet ingredients to the flour mixture whisk together until combined. Do not overmix.
Pour the thin batter into greased pan.
Bake in a preheated oven for 35-40 minutes or until a wooden toothpick or skewer comes out clean and the cake springs back when the top is lightly pressed.
Remove from the oven and place on a cooling rack to cool down completely before frosting.
Chocolate ganache frosting
Place 8 ounces of chopped chocolate in a small heatproof bowl and set aside.
In a small saucepan, heat butter and cream over medium-high heat until steaming hot and just beginning to simmer.
Immediately remove from the heat and pour over the chopped chocolate. Let stand for about 3 minutes to melt the chocolate, then whisk together until smooth.
Cover with plastic film and refrigerate. Whisk often, for about 45 minutes or until the frosting becomes thick and holds its shape.
Spread over the room temperature cake (directly in the pan) with an offset spatula.
Serve and enjoy!
Tips
- Sifting or whisking the dry ingredients together allows better distribution of the leavening agents. The process also aerates the dry ingredients making the final product lighter in texture.
- The best way to make sure you have a delicious banana chocolate cake is by using ripe bananas. Bananas with speckled brown spots on them have the most flavor. Using roasted bananas is another way to ensure a flavorful banana dessert.
- Avoid overmixing as this will result in a tough, rubbery cake due to gluten development.
- The batter is a little on the thin side, but not to worry. The end product has a light texture and the absolute perfect crumb! So do not be tempted to add extra flour.
- Cool the cake completely before icing with chocolate ganache frosting.
Recipe Variations
- Feel free to add a handful of walnuts or mini chocolate chips to the batter before baking it.
- If avoiding coffee, replace it with an equal amount of water.
- Replace the ganache frosting with a dusting of icing sugar.
FAQ

Hi Maria
Can i use frozen bananas
That’s all I have at the moment
Thank you
Maria
Great question Louise! I have used frozen bananas when making banana bread and muffins and the results are always great. I have never tried using frozen bananas with this dessert but it should be fine. Would love to hear about your results if you do decide to try it.
Jessica
Mmm, this looks divine! Love the addition of that chocolate frosting – yummmm! Can’t wait to try it this recipe out!
Maria
Fantastic Jessica, hope you get a chance to try it! Thanks for stopping by ♥
Julia
I, too, try to reduce sugar most of the time. And I also sub apple sauce for oil often. I love that this recipe has coffee and feeds a crowd!
Maria
This chocolate banana cake is really not overly sweet and comes together in no time at all… Thanks so much for taking the time to comment Julia ♥
Jackie
What a great looking cake, bet it tastes even better 🙂
Maria
Thanks Jackie! This chocolate banana cake is very popular with my family and friends. I love this recipe because it is so so easy to make 😉 The perfect chocolate treat for Valentine’s Day! Thanks for stopping by 🙂
Louise
Baked it recently and it was great. A lovely recipe indeed. Thanks Maria.
Maria
My pleasure Louise! I have a few bananas on my counter right now that are looking a little sad… debating whether to make this chocolate banana cake or banana muffins… decisions, decisions 🙂 Thanks so much for stopping by ♥

I love these ‘go to’ chocolate cake recipes that come together so quickly. I’m a fan of the Texas Sheet cake just for that reason with the cinnamon and chocolate. Thanks for giving me another option. I think my husband’s card group thinks I only know how to make one cake.
Maria
Hi Deb!
LOL…I think we are all the same. Once we have a recipe that works, like this chocolate banana cake, we stick with it. Appreciate the comment. Have a great week-end.
Maria
Hi mary,
This recipe looks delicious…
I would like to try it this weekend : )
Just a question – should i use espresso or regular coffee…or does it not matter??
Also….i would like to use the applesauce option you mention!
(I actually have homemade chunky applesauce!) So i should replace the full portion of oil by the applesauce?
Pls let me know! 🙂
Looking forward to trying this recipe!
Maria
Hi Maria,
I have always used regular coffee…you might get a more pronounced bitter taste with the espresso…also, I did cut back on the sugar, so the taste of the chocolate really comes through. I always replace only half the oil with the applesauce. I actually had a piece of leftover of this chocolate banana cake today (without the icing) and it’s still super moist. Would love to hear how the cake turns out for you! Thanks for taking the time to comment 🙂
Maria
Hi Mary,
Baked this cake today with my mom! Wanted to let you know how much we loved it!
Most impressive is the texture!
(Besides the chocolate flavor!!)
The moistness in the sponge!
Definately a keeper recipe !
Thanks for sharing it! 🙂
