Tips to Get the Perfect Sponge Cake

Do not mix the batter too much

Who likes a thick curdled sponge cake? Do you? Well, we don’t! If you over mix the batter, it’ll soon start to separate into lumps which could affect the final look and consistency of your delicious cake. So, to avoid this from happening, you need to make sure that you’ve got all the ingredients prepared beforehand. Don’t leave the batter standing while you’re fetching for some ingredient. Because every time you add a new ingredient, you’ll have to mix it into the batter, which will eventually thicken it, and we don’t want that, do we?

Milk to the rescue

If you feel like your batter is too thick and lumpy then add a teeny tiny bit of milk to smooth it out. Do not put your thick batter into the microwave or your cake will turn out all chewy and stodgy. Trust the milk, it’ll not only thin down your batter a little but will also help preserve the taste of your cake!

Everything at room temperature

You need to make sure that all your ingredients are at room temperature. This will ensure a better and easier mix. Having too warm or too chilly ingredients will cause you to mix up the ingredients way more in order to get the perfect blend. This would eventually cause over-mixing that we discussed in the first point!

Microwave Oven Sponge Cake FAQs

We’ve also fetched a bunch of frequently asked questions regarding sponge cakes and stuff that goes wrong with them. We hope the answers will help you out!

Can I refrigerate my sponge cake?

Do not refrigerate your sponge cake! Doing so will surely dry the poor cake out. Instead, freeze it. Freezing it will preserve the moisture in it. And when you’re ready to eat it, take it out an hour prior and let it come back to its original form at room temperature.

How long can I keep my sponge cake?

You can keep your sponge cake till 3 days at normal room temperature in an airtight container. But if you want to store it for longer periods of time, you can freeze it and later allow it to get back in shape at room temperature.

Why did my sponge cake deflate in the middle?

This happens because of over-beating the batter. When you mix the batter too much, it becomes a bit too airy. This air can eventually lead to deflation during the cooking time. So, to avoid this problem, don’t over-mix! Another reason for this could be the fact that you kept opening the microwave during the cooking time. You should also avoid cooling the cake in an airy and chilly place. Let it cool down at room temperature.
