Instructions
Step 1
In a mixing bowl, whisk together the egg yolks, vegetable oil, milk, and flour until the mixture is smooth and well combined. It's important to mix thoroughly so that there are no lumps left.
Once mixed, set the bowl aside to prepare the next part.
Step 2
In a clean bowl, whip the egg white using an electric mixer on medium speed until foamy. Gradually add the sugar and continue mixing until stiff peaks form. This usually takes a few minutes.
To enhance the flavor, fold in the lemon zest or vanilla paste gently.
Step 3
Carefully fold the meringue into the biscuit batter. Use a spatula and be gentle to avoid deflating the meringue. The goal is to create a light and airy mixture.
Once combined, you're ready to transfer this mixture into a piping bag.
Step 4
Fill the empty egg shells with the mixture using the piping bag, filling them to just over half full.
Preheat your oven to 180 degrees Celsius (356 degrees Fahrenheit) while you complete this step.
Step 5
Place the filled egg shells on a baking tray and bake in the preheated oven for about 15 minutes. Keep an eye on them to ensure they do not over-bake.
Step 6
Once baked and cooled, feel free to get creative! You can decorate your biscuits with food-safe markers, paints, or chocolate. Make it a fun activity!

Equipment
A sturdy mixing bowl is key for combining ingredients. Look for one with a non-slip base to keep it stable while you whisk.



A good whisk is essential for aerating the egg whites. Opt for a balloon whisk for the best results!



Use a piping bag to fill the egg halves with the batter easily. If you don't have one, a resealable plastic bag with the tip cut off works perfectly.



Make sure your oven is properly preheated to 180 degrees Celsius before baking. An oven thermometer can help ensure accurate temperatures!



A flat baking tray will help achieve even baking. Always line it with parchment paper for easy removal!
Variations
Vegan Variation: Replace eggs with flaxseed meal mixed with water (1 tablespoon flaxseed + 2.5 tablespoons water = 1 egg). Use plant-based milk instead of regular milk, and ensure your oil is vegan-friendly. This way, everyone can enjoy your fluffy cake without compromise! 🌱
Faq
- Can I use regular milk instead of plant-based milk?
Yes, you can! However, if you're aiming for dairy-free, stick with almond, soy, or oat milk for your vegan version.
- What do I do if my sponge cake is too dense?
This might happen if the egg whites weren’t whipped enough or if you overmixed the batter. Next time, whip your egg whites until stiff peaks form and gently fold them into the yolk mixture.
- How can I store leftover sponge cake?
Store it in an airtight container at room temperature for up to 3 days, or freeze for up to a month. Just make sure to wrap it well!
- Can I flavor the sponge cake?
Absolutely! You can add lemon zest, cocoa powder, or spices like cinnamon to give your sponge unique flavors.
- Why is my sponge cake sticking to the baking tray?
Ensure the tray is properly greased and lined with parchment paper. A light dusting of flour after greasing helps prevent sticking, too.
- How do I achieve a perfect rise?
Make sure not to skip the step of aerating your egg whites—this step is crucial for creating a light and fluffy texture!
