📌 What's In Chocolate Banana Cake?
11 Ingredients to make chocolate banana cake
- Banana
- Use ripe bananas for the best result.
- Egg
- It helps to create a soft texture.
- Oil
- I used olive oil. You can also use regular oils, such as canola and vegetable oil.

- The flavor matches so well with the banana. You can omit it if you like.
- Granulated sugar
- It helps to create a moist & soft texture.

- Baking soda reacts to acid (cocoa powder and vinegar for this sponge) and helps to create a fluffy cake. That is why it is often used for chocolate cake recipes.
- Hot water
- Use hot simmering water.
Ganache

- I used 58% Couverture chocolate. You can use your favorite chocolate.

Now, let me share detailed tips on each step, which are crucial for making chocolate banana cake successful.
Preparation
- Preheat the oven: to 365 F | 185 C
- Coat a thin layer of butter inside the pans. This prevents cakes from sticking to the pans.
Step 1: Mix all the dried ingredients.
First, add sugar and salt to a bowl.
Sift in all-purpose flour, cocoa powder, baking powder, and baking soda to eliminate lumps of flour.
Whisk well until they look even. And set it aside.
Step 2: Mash bananas.
Banana for chocolate cake 🍌
I highly recommend using ripe bananas for this cake. Not only it's easier to mash it, but it also gives the cake a better texture and sweetness. You'll see brown stains around the skin when they are perfectly ripe.
👩🏻🍳 If your banana is not ripe enough, leave it outside in a warmer place. Or add apples in the same bag to fasten the ripe process.
Mash bananas until it looks like an oatmeal breakfast meal:
I like to leave small pieces so I can see them slightly when I slice the cakes. You can use a fork a masher to do so.
Step 3: Mix all the wet ingredients.
Add whole eggs, oil, and vanilla extract. And mix until they look nice and even.
💬 I usually start heating the water after mixing the wet ingredients. When heating the water too early, it starts boiling and evaporates too much.
Step 4: Add the dried ingredients to the wet ingredients and mix.
Use a spatula to mix them. The batter is quite thick, especially at the very beginning.
Mix until it is evenly incorporated.
Step 5: Add hot water and mix.
Eggs might get cooked if you add all the water at once. Add about ⅓-1/2 first, mix well, and add the rest.
Mix until it's evenly incorporated.
Step 6: Pour into pans and bake!
🔥 Bake at 365 F | 185 C for about 40 minutes until the center cooks through. (The time & temperature may vary depending on the oven.)
2 ways to check if the cake is baked enough
- Insert a toothpick and see if it comes off clean. You might see the toothpick is a little bit wet because of the mashed banana, which is fine. Just ensure it's not the wet batter.
- Touch the center of the cake. It should be dry and bounces back gently!
💬 Today, I am using 2 1.5-QT pans. You can use 1 larger pan instead or even cupcakes! Use any pans you have. Just adjust the baking time and temperature accordingly!
After it cools down
After they are out of the oven, let them cool down completely before you take them out from the pans. They are still very fragile while they are hot.
How to remove cakes from the pans
Insert a spatula or a small knife to ensure the cake is not sticking to the pan. Push the spatula inward slightly to detach the side and the bottom.
Step 7: Make ganache. (Optional)
I like to spread a generous amount of dark chocolate ganache on top to compliment this cake. It is optional, but I highly recommend trying it if you have extra time.
The moist, soft cake and silky, smooth ganache match so well. It's easy to make!
First, melt chocolate in a water bath.
Once the chocolate melts completely, add heavy cream.
I like to heat heavy cream slightly until it does not feel anything (or feel slightly warm) when you touch it.
💬 Add heavy cream gradually and mix well each time until the ganache looks smooth. I divided it into 4 - 5 times this time. The chocolate can get hardened quickly and leave pieces in the ganache when you add all the heavy cream at once.
Honey makes the ganache slightly shinier and softer, even after it cools down. (I've gotta say the difference is minor since only 1 tablespoon is added today.) And the flavor matches well with the banana flavor.
💬 Use a spatula to mix the ganache. The ganache can contain more air bubbles in it when it's mixed with a whisk. It just doesn't look so appealing.
Step 8: Spread ganache on top, slice & enjoy!
👩🏻🍳 The ganache might be too loose to coat on top of a cake right after it's made, depending on the temperature of the chocolate and heavy cream. In that case, set it aside for some time - It'll slowly get thicker!
As an option, sprinkle toasted walnuts on top! The crunchiness of the walnut matches so well with the moist cake and smooth ganache.
Or try other toppings such as different types of nuts, diced chocolate, etc.
💡 The ganache gets hard when it cools down completely, just like any other ganache. So do not chill the frosted cake in the fridge if you want to enjoy a smooth, soft ganache. I recommend making it right before serving the cake.
This chocolate banana cake is incredibly moist yet soft. It's the ultimate chocolate cake that is so simple to make but amazes guests with its incredible texture and flavor.

My husband and daughter declared your chocolate banana cake the best version they’ve ever tasted. The cake was very fluffy and wonderfully moist. The cocoa powder added a bit of bitterness and complexity which we prefer over other recipes using chocolate.
