Ingredients
- 2 ripe bananas (approximately 200–230 g peeled)
- 2 large eggs, at room temperature
- ½ cup granulated sugar (100 g)
- ⅓ cup vegetable oil (80 ml)
- 1 cup all-purpose flour (0000 flour, approximately 120–125 g)
- ¼ cup unsweetened cocoa powder (approximately 25 g)
- 1 teaspoon baking powder (4 g)

Instructions
Step 1: Prepare the Oven and Baking Pan
Preheat the oven to 175°C (350°F).
Lightly grease an 8-inch (20 cm) round cake pan or line it with parchment paper. You can also use a small square baking pan of a similar capacity.
Make sure the pan is ready before mixing the batter, as the baking powder begins working once the wet and dry ingredients are combined.
Step 2: Mash the Bananas
Peel the ripe bananas and place them in a large mixing bowl.
Using a fork, mash them thoroughly until they form a mostly smooth purée. A few small banana pieces are perfectly fine and will add little pockets of banana flavor to the finished cake.
Tip: Very ripe bananas with plenty of brown spots provide the best sweetness and moisture. Bananas that are still green or firm won’t mash as easily and may produce a less flavorful cake.
Step 3: Add the Eggs and Sugar
Add the eggs and granulated sugar to the mashed bananas.
Whisk by hand for approximately 1–2 minutes until the mixture is well combined and slightly frothy.
There is no need for an electric mixer. A hand whisk or fork works well for this simple batter.
If using vanilla extract, add it at this stage.
Step 4: Mix in the Oil
Pour the vegetable oil into the banana mixture.
Whisk until the oil is fully incorporated and the mixture looks smooth and glossy.
The oil helps keep the cake moist and tender, even after it has cooled.
Step 5: Combine the Dry Ingredients
In a separate bowl, sift together the flour, unsweetened cocoa powder, baking powder, and salt.
Sifting helps remove lumps from the cocoa powder and distributes the baking powder evenly throughout the flour.
If you prefer to use only one bowl, add the dry ingredients directly to the wet mixture through a sieve, but take care not to overmix the batter.
Step 6: Make the Chocolate Banana Batter
Add the dry ingredients to the wet banana mixture.
Using a spatula or wooden spoon, gently fold everything together until no large patches of dry flour remain.
The batter should be thick, smooth, and pourable. Avoid vigorous stirring or mixing for too long, as this can make the cake dense.
If using chocolate chips or chopped walnuts, fold them in gently at the end.
Step 7: Pour the Batter into the Pan
Transfer the batter to the prepared cake pan.
Use a spatula to spread it evenly into the corners and smooth the surface. Gently tap the pan once on the countertop to release any large air bubbles.
Step 8: Bake the Cake
Place the pan on the center rack of the preheated oven.
Bake for 30–40 minutes, depending on the depth of the pan and your oven.
Begin checking at around 30 minutes. Insert a toothpick into the center of the cake; it should come out with a few moist crumbs but no wet batter.
Avoid overbaking, because the cake’s soft texture depends on retaining moisture from the bananas and oil.
If the center still contains wet batter, continue baking for another 3–5 minutes and check again.
Step 9: Cool Before Slicing
Remove the cake from the oven and let it rest in the pan for 10–15 minutes.
Carefully turn it out onto a wire rack, if appropriate for your pan, and allow it to cool further before slicing.
For the softest texture, serve it slightly warm. The chocolate flavor becomes even more pronounced as the cake cools.
Step 10: Decorate and Serve
Enjoy the cake plain, or finish it with a light dusting of powdered sugar.
For a more indulgent dessert, drizzle the slices with melted chocolate or serve with whipped cream, fresh banana slices, or a scoop of vanilla ice cream.
Chef’s Tips for a Perfect Chocolate Banana Cake
- Use very ripe bananas: Brown-speckled bananas provide more flavor and natural sweetness.
- Measure flour carefully: Too much flour can make the cake dry. Weigh it if possible, or spoon it into the measuring cup and level it off.
- Use unsweetened cocoa powder: This gives the cake a richer chocolate flavor without adding unnecessary sweetness.
- Don’t overmix: Fold the batter only until the flour is incorporated to keep the crumb soft.
- Choose the right pan size: A very deep pan may require additional baking time, while a wider pan will produce a thinner cake that bakes faster.
- Avoid overbaking: Start checking early, because the cake can dry out if left in the oven too long.
- Let it rest: Cooling briefly helps the cake set and makes it easier to slice neatly.
Delicious Variations
Double Chocolate Banana Cake
Add ¼ cup chocolate chips to the batter for extra pockets of melted chocolate.
Chocolate Banana Walnut Cake
Fold in ¼ cup chopped walnuts or pecans for a nutty flavor and a little crunch.
Cinnamon Chocolate Banana Cake
Add ½ teaspoon ground cinnamon to the dry ingredients for extra warmth.
Less-Sweet Chocolate Banana Cake
Reduce the sugar slightly to ⅓ cup, especially if your bananas are very ripe. The cake will have a deeper, less sweet cocoa flavor.
Chocolate Banana Muffins
Divide the batter among 10–12 lined muffin cups and bake at 175°C (350°F) for approximately 15–22 minutes, checking for doneness toward the end.
Chocolate Banana Snack Cake
Spread the batter in a greased 8-inch square pan and serve in small squares. This makes a convenient treat for lunchboxes, picnics, and afternoon snacks.
Make-Ahead Instructions
You can prepare and mash the bananas shortly before baking. For the best rise, mix the wet and dry ingredients together just before the cake goes into the oven.
The cake itself can be baked a day ahead. Allow it to cool completely, then cover it tightly to help preserve its moisture.
Storage Instructions
Room Temperature: Store the completely cooled cake in an airtight container in a cool room for up to 2 days.
Refrigerator: Refrigerate in an airtight container for up to 5 days if your kitchen is warm. The cake may become slightly firmer when chilled, so let slices sit at room temperature briefly before serving.
Freezer: Cut the cooled cake into individual slices, wrap them well, and store in a freezer-safe container for up to 2 months for best quality.
Reheating: Warm a slice in the microwave for approximately 10–15 seconds, adjusting as needed, to restore its soft texture.
Frequently Asked Questions
Can I make this cake without a mixer?
Absolutely! This recipe is specifically designed for hand mixing. A fork is enough to mash the bananas, and a whisk or spatula will combine the remaining ingredients.
Why is my chocolate banana cake dry?
It may have too much flour or may have been baked for too long. Measure the flour accurately and begin checking the cake after 30 minutes.
Can I use whole-wheat flour instead of all-purpose flour?
Yes, but the cake will be denser and may absorb more moisture. For the closest match to the original texture, use all-purpose flour.
Can I replace the oil with butter?
Yes, although butter is not needed in this recipe. If substituting, use approximately 75 g melted butter in place of the 80 ml oil. The flavor and moisture retention will differ slightly.
Can I reduce the sugar?
Yes. Ripe bananas naturally contribute sweetness, so you can reduce the sugar to ⅓ cup if you prefer a less-sweet cake. Expect a slight difference in flavor and texture.
How can I tell when the cake is done?
The surface should look set, and a toothpick inserted into the center should come out without wet batter. A few moist crumbs are fine; the cake should not be baked until completely dry.
Serving Suggestions
Serve this cake with a cup of coffee, tea, or cold milk. For a simple dessert, add a little whipped cream and fresh banana slices. For chocolate lovers, a drizzle of melted dark chocolate or a spoonful of chocolate sauce makes it extra special.
