This Banana Chocolate Marble Cake combines the sweetness of ripe bananas with rich cocoa for a soft, moist loaf full of flavor. Each slice shows off a beautiful marbled swirl — part banana, part chocolate — that looks impressive yet is so easy to make. The mashed ripe bananas keep the cake incredibly tender and naturally sweet, while the chocolate batter adds a deep, slightly bittersweet contrast. Serve it on its own, with a cup of tea or coffee, or lightly warm it and top with a scoop of ice cream for something extra special.
I absolutely love banana flavor, especially in cakes — it gives such a warm, sweet aroma and keeps the crumb soft and tender. But I know it’s not for everyone. Some people just can’t get used to the cooked flavor of fruits in desserts. Still, if you enjoy banana bread or anything with that natural fruity sweetness, this cake might become one of your favorites.
It’s perfect for breakfast, tea time, or as a cozy afternoon snack — and if you warm up a slice and add a bit of chocolate drizzle or ice cream, it turns into a simple but wonderful dessert.
Ingredients:
- 3 ripe bananas (about 300g)
- 3 eggs
- 120g brown sugar
- 225g all-purpose flour
- 120g neutral oil (vegetable or canola)
- 12g baking powder (about 3 tsp)
- 25g cocoa powder (about 1.5 tbsp)
Instructions:
- In a blender or bowl, combine the bananas, eggs, sugar, and oil.
- Blend or mix until smooth.
- Sift in the flour and baking powder.
- Stir gently until just combined—do not overmix.
- Split the batter evenly into two bowls.
- Sift the cocoa powder into one bowl and mix well to create the chocolate portion.
- Grease or line baking pan - I used a 12cm x 20cm glass baking pan.
- Using a spoon, alternate scoops of plain and chocolate batter, layering one on top of the other for a marbled effect.
- Bake in a preheated oven at 170°C (340°F) for about 50 minutes, or until a skewer inserted into the center comes out clean.
- Allow the cake to cool completely before slicing.
- Store in the refrigerator for up to 2–3 days.
