How to Make Japanese Cotton Sponge Cake

published by Agnes Chin on Sep 20, 2009

Japanese cotton sponge cake is very much different in texture than the normal sponge cake. You need to taste it to tell the difference.

If you are like me trying to bake the kind of sponge cake that is smooth, moist, bouncy and rich enough to eat on it own, then Japanese cotton sponge cake is what you are looking for.

This is the first time I baked Japanese cotton sponge cake, not only I was very satisfied with it, I received good  comments too.

Here is the recipe which I would like to share with you :

Ingredient A

  • 60 gm melted butter

  • 80gm flour

  • 80ml full cream milk / UHT milk
  • 6 egg yolks + 1 egg (depending on the size of the egg, 5 egg yolks will be sufficient with bigger size eggs).

Ingredient B

  • 6 egg white (or 5 bigger size eggs)
  • 90gm sugar
  • a pinch of salt

Method of preparation

  1. Preheat oven to 170C
  2. Beat 6 egg yolks and 1 egg until creamy, approximately 5 minutes.
  3. Add in flour and alternate it with milk.
  4. Add in melted butter and mix well.  Set aside the egg yolks batter.

  1. In a clean mixing bowl, whip egg whites with sugar and salt until soft peak.
  2. Fold the egg white mixture into egg yolks batter gently till well combined.  You may use hand to do the mixing.
  3. Pour the mixture into a slightly greased and line baking pan (I used the 8″ square pan).
  4. Bake for 35 minutes or until the skewer comes out clean. Do not reduce the heat during baking as this will cause the cake to collapse prematurely.
  5. When the cake is out from the oven, let it sits for 2 minutes before unmoulding it.  The cake tends to collapse a little during the sitting time.

The cake just out from the oven

It has collapsed a little after 2 minutes.

Try this recipe and leave me comments on the outcome.  Happy baking!

    You did not add any baking soda or baking powder for it to become spongy ? You may have missed in the receipe. Kindly update.

    Sponge cakes don’t use baking soda or powder, thats why they’re also known as egg foam cakes. Whipping up the egg whites is what makes it “spongy”

    Also greasing the pan and putting parchment paper on the bottom is so the cake comes out of the pan with ease, it doesn’t affect the texture or taste of the cake.

    Hi,
    I made this cake twice and didn\’t succeed at all. The filling is hard like egg tart. The second time when I made it, I left the mixed batter 45 mins at room temperature before putting in the oven. Do we suppose to use electric mixer to whip the egg yolk and egg white? I use quite a thick round pan and takes 55mins to make it completely cooked.

    Can someone point out what went wrong please? Thank you!
