This chocolate banana swirl Cake is perfect for any occasion—whether it’s a quick dessert after dinner or a treat for a gathering. Easy to make, this cake will be a family favourite. Start by preheating your oven to 350°F (175°C). Grease a 9-inch loaf pan and line it with parchment paper for easy removal of the cake after baking. In a large mixing bowl, mash the ripe bananas using a fork until they are smooth.

Add in the sugar, eggs, melted butter, and vanilla extract. Use a whisk or an electric mixer to blend everything until the mixture becomes smooth and creamy. In another bowl, sift together the flour, baking powder, baking soda, and salt. This will help ensure that your cake turns out light and fluffy. Gradually add the dry mixture into the bowl with the wet ingredients, alternating with milk.

Mix gently using a spatula until everything is just combined. Be careful not to overmix, as this could lead to a dense cake. Separate the batter into two equal portions. In one half of the batter, sift in the cocoa powder and gently fold it in until fully incorporated. You will now have one banana batter and one chocolate batter. Pour half of the banana batter into the prepared loaf pan, spreading it evenly with a spatula.

Then, pour half of the chocolate batter on top. Use a toothpick or knife to gently swirl the batters together, creating a marbled effect. Repeat this process with the remaining banana and chocolate batters, swirling them once more. Place the loaf pan in the preheated oven and bake for about 50-60 minutes, or until a toothpick inserted into the centre comes out clean.

Every oven is different, so start checking around the 50-minute mark to avoid overbaking. Once the cake is done, remove it from the oven and let it cool in the pan for about 10 minutes. After that, transfer it to a wire rack to cool completely then drizzle the melted chocolate over the cake. Slice and enjoy the delicious combination of chocolate and banana in every bite. This chocolate banana swirl cake is a delightful way to indulge in two beloved flavours—chocolate and banana.

The swirling technique not only makes the cake visually appealing but also gives each bite a perfect balance of both flavours. Serve it with a cup of coffee or enjoy it on its own.
