Chocolate sponge cake is a home baker’s must-have. It’s the foundation for countless different cakes but uses only four simple ingredients. Prepare to be amazed!

Chocolate sponge cake cut open

I grew up in Ukrainian/Slavic culture with this moist chocolate sponge cake. Despite its impressive texture, appearance, and taste, this cake comes together so simply. It doesn’t require oil or butter, just sugar, flour, cocoa/cacao powder, and eggs (and there’s no reason to separate the egg whites and egg yolks here!). It’s a recipe that has been passed down generation to generation in my family, and now I’m passing it on to you!

This chocolate sponge cake is the foundation to so many cakes my family and I make including my strawberry chocolate cake, chocolate hazelnut cake, drunken cherry cake, chocolate liqueur cake, and so much more. It makes the yummiest cake layers in any cake. It really is a staple in any Ukrainian/Slavic bakers’ kitchen, and soon to be yours, too.

Mmm… chocolate! This chocolate sponge cake recipe is the chocolate version of my regular sponge cake recipe (for the video recipe, click here). Use any cocoa powder but my absolute favorite is this one. It’s my go-to for baking!

How to Make Chocolate Sponge Cake

While the ingredients are simple, the technique makes all the difference. Since there’s no baking soda or baking powder in this recipe, the air that is beat into the batter serves as the leavening agent. Check out the process below.

  • Beat the eggs: In a large bowl and with a stand or handheld mixer, beat the eggs with the sugar until the batter triples in volume. For a stand mixer, this takes about 10 minutes but may take longer for a hand mixer. The batter is the correct consistency when you get thick ribbons dripping off the whisk.
  • Add in the first dry ingredients: Sift in the flour and cocoa powder and gently stir.
  • Fold in the remaining ingredients: Using a silicone or rubber spatula, fold in the remaining dry ingredients. Be gentle and avoid over mixing as this can compromise the fluffiness of the cake.
  • Bake: Add the cake batter to an oiled or parchment paper lined baking pan. Bake at 350°F for 30 minutes. Use in your favorite recipes!

Hot tip: A reader suggested adding ultra-fine coffee/espresso powder to the cake for a bit of coffee flavor. If you do so, add about a tablespoon and make sure it’s super fine so it doesn’t affect the cake’s texture.

Tips for the Best Chocolate Sponge Cake

You don’t need to have the background of a fancy French baker to make the perfect sponge cake. Here are my top tips and tricks to nail this recipe each time.

  • Bring the eggs to room temperature: Take the eggs out from the fridge a little early so they can warm up. Room temperature eggs beat better and get more airy and fluffy better than cold eggs.
  • Use the right flour: A high-quality, all-purpose flour is what you need for the perfect sponge cake — no cake flour required here. I love European or Canadian brands since they typically have a higher protein content.
  • Beat the egg mixture long enough: It’s important to continue beating the egg mixture long enough until you get thick ribbons and can create shapes with it. In a stand mixer with the whisk attachment, this takes about 10 minutes on medium-high speed. Hand mixing often doesn’t work to get the thick ribbons.
  • Avoid overmixing: Fold your dry ingredients in very carefully and gently with a spatula (don’t mix!). Stirring or whisking (or overmixing) destroys the cake’s fluffiness and results in a flat, dense cake.
  • Line or oil the pan: Prevent your cake from sticking and cracking by lining or oiling your round cake pan. If you do run into issues, take a butter knife and run it along the edges of the pan to loosen the cake. Either way, make sure to give the cake time to cool to room temperature and set before you attempt to remove it.
  • Shake the pan: For a nice, even cake top, shake the pan slightly before placing it in the oven. This helps remove any air bubbles and makes frosting the cake (if you want to) much easier and smoother later.
  • Resist the urge to open the oven: When baking, it can be really tempting to open the oven and check in on your cake. Resist the urge! When cold air enters the oven, it can cause the center of the cake to sink.
  • Gauge doneness with a toothpick: If in doubt that the cake is done baking, use a toothpick to check. Insert it into the center, and if it comes out clean or with a few small crumbs, the cake is done.
  • Cool on a wire rack: After you let your sponge cake cool in the cake pan for 10-15 minutes, transfer it to a wire rack to finish the process. This helps the bottoms and sides set without cracking.

Tip summary: If you only follow two tips when baking, I’d say make sure to whip your eggs to the right consistency and avoid over-mixing the batter.

Storing/Making Sponge Cake in Advance

Chocolate sponge cake is the perfect cake to make a few days in advance! Here are some options on how to store it:

  • Counter: Store it for up to two days on the counter in an airtight container.
  • Refrigerator: Refrigerate the cake in an airtight container for up to a week.
  • Freezer: Freeze the cake for up to three months. Store it in a flat airtight container so it doesn’t lose its shape!

Hot tip: If you have a springform pan, use it! Since the sponge cake is so delicate, it helps ensure you don’t break or crack the cake. Just makes sure it’s 9 inches or bigger.
