Best moist chocolate sponge cake recipe

Some recipes for chocolate sponge cake call for a boxed cake mix, but our goal is to level up your everyday baking. My recipes are always made from scratch with familiar ingredients and no fancy equipment. You can have this cake batter ready to bake in under 15 minutes! And the steps are all super simple to follow and never complicated. You get professional, consistent results with hardly any effort!

I also have a baking hack to get the best chocolate flavor in this chocolate sponge cake recipe. Unsweetened cocoa powder and freshly brewed coffee are the secret to an intense chocolatey taste. The coffee really heightens the chocolate taste without being noticeable, trust me! You can use decaf coffee, but this is a pro tip worth trying.

My best advice on the ingredients

I use specific ingredients in specific ways to get the best, professional results in this recipe.

All-purpose flour is fine for these chocolate sponge cakes; you do not need to use cake flour. Whole milk is always the best when making sponge cakes or other baked goods like muffins and cupcakes. A mixture of brown and white sugar gives you a tender bite and a hint of molasses for that deeper, richer flavor. And, as mentioned above, Dutch Process cocoa powder is superior in taste and how it reacts with other ingredients to give you the best results.

Make sure your milk and eggs are at room temperature before you begin for proper emulsification, and don't skip the salt! It enhances all the flavors and balances sweetness, so you definitely need to include it.

Last but not least, always weigh the ingredients using a digital scale for accuracy!

Whisk, fold, ready to go into the oven

Preheat the oven to 180°C / 356°F (without the fan).

Prepare three 15 cm (6 inch) round cake pans with parchment paper. Use this cake pan conversion article to make the sponges in different sizes or shapes.

Use an electric hand mixer (or a stand mixer or even a hand whisk) to mix the room-temperature wet ingredients (the oil, sugar, milk, vanilla extract, coffee, and eggs) together for a minute or two until combined.

Then, sift the dry ingredients (the flour, baking soda, baking powder, salt, and cocoa powder) into the wet ingredients and and fold them together with the help of a rubber spatula or hand whisk just until combined, for a few seconds. Avoid using a stand mixer or electric hand whisk at this stage, as you might overmix the batter.

That´s it! I told you it´s easy!

Bake and enjoy

Once the batter is mixed together, pour it into each prepared cake pan.

Place the cake pans in the oven, ideally on the center rack, and close the door. Avoid opening the oven door during baking, as this alters the baking environment.

Bake chocolate sponge cake for 25-30 minutes at 180°C / 356°F (without the fan). To test if it is baked enough, insert a toothpick into the center of the sponge cake. If the toothpick comes out clean, your chocolate cakes are baked. The top of the sponge will feel bouncy to the touch, and the edges of the sponge cake will also be slightly pulled away from the edges of the pan.

Remove the baked chocolate sponge cakes from the oven and either let them cool in the pan or very carefully flip them over onto a cooling rack. Either way, don't try to cut them or frosting them while they are still hot.

Substitute the ingredients wisely (or possibly not at all)

This homemade chocolate cake is a very precise recipe, which can make substitutions difficult. Each ingredient plays a role, so removing one of them will have an impact. If you substitute ingredients, you will also need to reformulate the recipe somewhat and adjust the quantities and ratios of the other ingredients. Unfortunately, I cannot provide instructions to accommodate every diet!

Here is a helpful guide on how to substitute oil in cakes, if you need that.

To make this simple chocolate sponge recipe egg-free, you could try one of these egg substitutes. However, the sponge might have a different taste and texture. The same is true of using different flours. Read more about the best flour to use in cakes and baking.

Dutch-processed cocoa powder yields far superior results to sugary cocoa powder, so I do not recommend using it. You could partially replace the sugar in the recipe with honey, but again, it will impact the texture and taste. 

However, you can replace the milk with any vegan substitute, such as oat milk. If you don't want to use the coffee, substitute it with the same amount of water or milk to replace the moisture.

Need to bake ahead? Store and freeze like a pro

The best thing about this recipe (other than the taste) is how easy it is to store. I recommend removing each cake from its cake pan, wrapping them in plastic wrap, and then placing them into a ziplock bag. You can fit 2 of the 6-inch cakes into one large ziplock bag. Once all are wrapped up, they can be stored in the fridge for up to 5 days until you are ready to use them.

You can also freeze chocolate sponge cakes in this manner for up to three months. I recommend always wrapping each cake in plastic wrap first and then placing it into a sealable plastic bag to prevent freezer burn.

Try some flavor variations

A classic chocolate sponge cake is a super versatile recipe to have in your back pocket, and it can also be adapted in a few simple ways to add more layers of flavor.

Try replacing a small portion of the flour with ground nut flour for added richness and taste. You can see how I have added hazelnut flour to this Ferrero Rocher cake, which has always been so popular.

A sprinkle of ground chili powder or ground cinnamon can add a whole new level of flavor to your perfect sponge cake. Add these ground spices to the dry ingredients before you add the egg mixture to form the batter. 

A tablespoon of freshly grated orange zest or even lime zest would add delicious citrus flavor to this cake.

You could also drop a handful of fresh strawberries into the cake batter just before baking. The possibilities are endless!

My final expert tips

1. To quickly bring eggs to room temperature, put them in a sink of hot tap water for 5 minutes.
2. For perfectly even, moist sponge cake layers, weigh the total batter on your digital scale and then divide it evenly among your cake pans. 
3. Bake the cake immediately after you have made the batter; don't wait.
4. The oven temperature for chocolate sponge cake is vital. Consider using a digital oven thermometer to ensure you are baking at the correct temperature.
5. I also like to preheat the oven to 29°C / 68°F and then turn it down to the correct temperature once the cake is inside. This compensates for the drop in temperature when you open the door.

Troubleshooting

If your cake is dry, it might not have the correct ratio of ingredients, so next time make sure to weigh the ingredients using a digital scale. As an example, sugar is a tenderizer, so reducing it can dry things out. The oven might also be too hot or you overbaked it, so check that you are baking at the right temperature!

If your chocolate sponge cake sunk, it might be underbaked. Check out my article on sinking cake and how to avoid it.

If your sponge domes, the pan might be too small! Using a cake pan strip can also help to ensure an even rise. Check my cake pan sizes conversion for larger or smaller cakes.

If your sponge cake sticks to the pan, it probably wasn't prepared properly. Brush it with oil using a silicon pastry brush before lining it with parchment paper.
