Frequently Asked Questions About Simple Vanilla Sponge Cake
Can I use regular milk instead of buttermilk?
You can substitute buttermilk by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk and letting it sit for 5-10 minutes. However, real buttermilk yields better texture and flavor.
What makes sponge cake different from regular cake?
Sponge cake is usually lighter with a fine, airy crumb. This version includes butter and buttermilk for added moisture, making it richer than traditional sponge cakes.
Can I make this recipe into cupcakes?
Yes! Fill cupcake liners 2/3 full and bake at 350°F (175°C) for 18-20 minutes. Start checking doneness with a toothpick around the 17 minute mark.
How do I keep the cake from sinking?
Ensure your oven is preheated and avoid opening the door during the first 25 minutes of baking. Also, measure baking powder and baking soda accurately.
Can I freeze this cake?
Absolutely. Once cooled, wrap the cake in plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the fridge or at room temperature before serving.
Can I make this sponge cake gluten free?
Yes, use a 1:1 gluten free flour blend that includes xanthan gum. The texture may vary slightly but still turns out soft and fluffy.
What frosting pairs best with vanilla sponge cake?
Classic vanilla buttercream, whipped cream, lemon glaze, or even chocolate ganache all work beautifully. You can explore more pairing ideas in our vanilla cake recipes.
Why is my sponge cake dense?
Overmixing the batter or using cold ingredients can result in a dense texture. Always mix gently and use room temperature ingredients.
Can I bake this in a bundt or loaf pan?
Yes, but baking times will vary. A loaf pan may need up to 45 minutes. Always use the toothpick test to check for doneness.
Can I add cocoa powder to make it chocolate?
Yes. Replace ¼ cup of flour with unsweetened cocoa powder for a chocolate variation. You may also want to increase sugar slightly for balance.
