Moist Chocolate Cake with Ganache (Easy One-Bowl Recipe)

Chocolate cake has existed in many forms since the 19th century, but not all chocolate cakes are created equal. Some are rich but dense, while others are light but dry. Modern home bakers often look for a cake that balances deep chocolate flavour with a soft, moist crumb and reliable results.

This recipe follows the style of popular American one-bowl chocolate cakes, using cocoa powder, oil, and hot liquid to create a rich flavour and tender texture. The hot coffee or water helps bloom the cocoa, intensifying the chocolate taste without making the cake heavy.

If you are short on time, you can skip the chocolate ganache and serve the cake with whipped cream and sprinkles instead — a simple, fuss-free option that also makes it fun for children to help decorate.

Recommended Tools & Tips

A few well-chosen tools and small techniques make a noticeable difference to the texture and finish of this cake.

Using two Round Cake Tins (20cm, 8inch) ensures even layers and a shorter baking time. If using a single tin, extend the baking time and check carefully to avoid overbaking.

Weighing ingredients with a Digital Kitchen Scale gives far more consistent results than measuring by volume, especially for flour and cocoa powder.

Use Dutch-Processed Cocoa Powder as it has been treated to reduce acidity, resulting in a darker colour and smoother flavour, and is best used in recipes with baking powder. Cocoa powder tends to clump easily. Sifting helps it blend smoothly into the batter, preventing dry pockets and ensuring an even chocolate flavour throughout.

Mixing bowl and whisk
This is a one-bowl recipe that can be mixed entirely by hand. Whisk just until smooth — overmixing at this stage can slightly toughen the crumb.

Hot coffee or hot water
Adding hot liquid is essential. It “blooms” the cocoa powder, allowing the chocolate flavour to deepen. Coffee enhances the chocolate without making the cake taste like coffee.

Thin batter consistency
The batter will look quite thin compared to typical cake batters. This is intentional and is what gives the cake its soft, moist texture.

Oven positioning
Bake on the middle rack for even heat distribution. Avoid opening the oven door too early, as this can cause the cake to sink in the centre.

Testing for Doneness
Insert a Cake Tester or skewer into the centre of the cake. It should come out clean or with a few moist crumbs, but not wet batter.

Cooling the cake
Allow the cake to cool in the tins for about 10 minutes before transferring it to a Cooling Rack. Cooling completely on a wire rack prevents trapped steam from making the base soggy.

Ganache consistency
After preparing the ganache, let it cool at room temperature for 20–30 minutes, stirring occasionally, until slightly thickened but still pourable. This ensures a smooth, glossy finish that spreads easily without running off the cake.
