Ingredients
- 2 cups all-purpose flour
- 1 cup granulated sugar
- ½ cup unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 3 ripe bananas, mashed
- ½ cup vegetable oil
- 2 large eggs
- 1 teaspoon vanilla extract
Instructions
1. Prepare the Oven
Preheat the oven to 350°F (175°C). Grease and line a cake pan with parchment paper.
2. Mix the Dry Ingredients
In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt.
3. Mix the Wet Ingredients
In a separate bowl, whisk the mashed bananas, vegetable oil, eggs, and vanilla extract until smooth.
4. Combine
Gradually add the wet mixture to the dry ingredients. Gently fold until just combined. Do not overmix.
5. Bake
Pour the batter into the prepared pan and smooth the top.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
6. Cool
Let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.

Common Mistakes to Avoid
Overmixing
Mix the batter only until the flour disappears. Overmixing can make the cake dense.
Using Unripe Bananas
Ripe or overripe bananas provide better sweetness, moisture, and banana flavor.
Overbaking
Check the cake a few minutes before the suggested baking time. A toothpick should come out clean or with a few moist crumbs.
Opening the Oven Too Often
Avoid opening the oven during the first part of baking, as sudden temperature changes can affect the cake’s rise.
