    This Plain Sponge Cake is soft, airy, and perfect as a base for layered cakes or enjoyed on its own with a dusting of powdered sugar. You can serve this topped with strawberries and cream, divided into layers and filled with buttercream or simply slice and serve with a dollop of creme fraiche and soft fruit on top. This is a canvas for you to make your own!

    Ingredients and substitutions for Sponge Cake

    • Butter: Butter must be room temperature here to create the nice and fluffy base of the sponge cake which allows more air to be whipped up and help the sugar begin dissolving. Unsalted was used here as this is fresher than salted, however, you could absolutely substitute salted butter here.
    • Sugar: Superfine or caster sugar gives our cake itโ€™s sweetness without overly flavoring the cake allowing the vanilla to shine and the strawberries in between. You could substitute with raw sugar or half and half with brown sugar, though your cake would have slightly more caramel flavor. Icing or confectionerโ€™s sugar is best here because it dissolves into the butter due to itโ€™s incredibly fine texture.
    • Plain flour: You don't need much and don't want to overwork the dough so you don't make these too stiff. However, you can substitute with self-raising flour which is most commonly found in
    • Eggs: The eggs need to be room temperature here to bind with the butter and sugar as room temperature eggs allow more air into them giving our sponge that nice and light texture.
    • Vanilla extract: Vanilla extract acts as a flavor enhancer, without it the cake would have no depth. If serving this cake plain, using vanilla paste in place of the extract is going to intensify the vanilla flavor and is definitely recommended here.

    FAQ's for the best Sponge Cake

    Do the ingredients need to be room temperature?

    Yes, to create the best sponge cake your butter and eggs need to be room temperature. This allows the butter to whip up into a fluffy texture and combine with the sugar. Room temperature eggs allow for better aeration resulting in a fluffier texture that results in a the crumb.

    Why did my sponge cake sink in the middle?

    Sponge cakes may sink due to underbaking, opening the oven door too early, or overmixing the batter which deflates the air bubbles. Be sure to bake at the right temperature and avoid disturbing the cake while it's rising.

    How many times was this recipe tested?

    Traditionally sponge cakes have an even weight of butter, sugar, flour and eggs so 1 test was made with this ratio with the inclusion of other ingredients, though the result wasnโ€™t as satisfactory as my Victoria Sponge Cake. A test was made with reverse creaming and this ended up with a crumb too heavy for a sponge cake so that is not recommended. Rise of cake without egg white is less even whilst the egg white cake had a more even rise and the perfect light texture.

    • 6 grams / 1 ยฝ teaspoons baking powder

    Notes

    • Vanilla flavor: If serving this cake plain, using vanilla paste in place of the extract is going to intensify the vanilla flavor. Alternatively, you could flavor this with lemon zest or almond extract.
    • Cake tin: A round spring form tin was used, however, a standard cake tin of similar size would also work well.
    • Best stored: In an airtight container at room temperature for up to 2 days. For longer storage, wrap tightly and refrigerate for up to 5 days, or freeze for up to 3 months.
