If you've never baked a sponge cake before or want to prepare a simple, fuss-free treat, try making a basic sponge cake. You only need flour, sugar, eggs, and butter to create a straightforward cake that you can top with your favorite frosting or enjoy as is. Once you're comfortable with baking, you can experiment by adding flavors or making slight variations.
Ingredients
- 220 g all-purpose flour
- 1 teaspoon (4 g) baking powder
- 1/2 teaspoon (3 g) baking soda
- 1/2 teaspoon (2.5 g) salt
- 170 g unsalted butter at room temperature
- 300 g granulated sugar
- 2 large eggs at room temperature
- 180 ml buttermilk or whole milk
Makes one 23 cm diameter sponge cake
Steps
Mix the Dry Ingredients

Baking soda and baking powder are essential for helping the cake rise during baking. If it's been a while since you last baked, check the expiration dates on the baking powder and baking soda packaging to ensure they are still effective.
- Using room-temperature butter is crucial as it blends more easily with sugar, resulting in a light and airy cake rather than a dense one.
- Stop the mixer occasionally to scrape down the sides of the bowl to ensure all the butter is incorporated.
Tip: If you prefer a less sweet cake, you can reduce the sugar to 250g. Keep in mind that sugar contributes to the cake's golden-brown color, so using less sugar may result in a lighter-colored cake.
- Using room-temperature eggs helps retain air in the batter, ensuring the cake rises properly in the oven.
- Stop mixing as soon as the last of the dry ingredients are incorporated. Overmixing can result in a dense or tough cake.
Bake the Cake

- Metal pans are recommended as they conduct heat better than glass or ceramic pans.
- For cupcakes, place paper liners in a muffin tin with 16 or 18 slots.
Tip: Parchment paper makes it easier to remove the cake from the pan and prevents the crust from over-browning during baking.
- If you're making cupcakes instead of a whole cake, consider using a cookie scoop to portion the batter evenly.

- Test the cake's doneness by inserting a toothpick or skewer into the center. If it comes out clean, the cake is ready; if not, bake for a few more minutes and check again.
- For cupcakes, check after 20 minutes of baking.
Tip: If baking at high altitudes, consider adding an extra egg to prevent dryness. You may also reduce the baking time by 5-8 minutes as the cake will cook faster.
- You don’t need to worry about the cake sticking, as the parchment paper lining will help release it easily.
- No oven mitts are needed at this stage, as the cake will have cooled completely.
- Store leftover cake in an airtight container at room temperature for up to 2 days. You can also refrigerate it for up to 7 days, though it may dry out slightly.
Explore Variations of Sponge Cake

- Consider topping the chocolate sponge cake with cream cheese or chocolate buttercream frosting.
Red Velvet Variation: Add 1 tablespoon of cocoa powder to the dry ingredients and mix ½ tablespoon of white vinegar with 30 ml of red food coloring into the wet ingredients.
- For a citrus-flavored cake, try adding the zest of 1 lemon, 1 orange, or ½ grapefruit to the sugar before creaming it with butter to infuse the citrus oils into the mixture.

- For a more intense flavor, stir in 1 tablespoon (7g) of grated ginger into the butter and sugar mixture.

- For extra crunch, use roasted nuts instead of raw ones.

- For a vegan sponge cake, you’ll also need to use vegan butter and dairy-free alternatives like almond or oat milk instead of buttermilk.

- If using gluten-free alternatives like almond or chickpea flour, follow the manufacturer’s baking instructions. Keep in mind the texture may be more crumbly compared to cakes made with all-purpose flour.
Tips
- If you don’t have a mixer, you can use a wooden spoon and mix by hand.
- Consider adding a handful of dried fruits, chocolate chips, or roasted nuts to the batter for extra flavor and texture.
