Wow…I’ve neglected my blog for a long time.
The recipe that I am going to write about here is another Japanese recipe that I’ve made back in fall (it is winter now 
). Anyways, I found this recipe on a Youtube video here. The video is Japanese and the video quality is not the best but the recipe is AWESOME. I’ve always wanted to find a good recipe for the Castella or also known as “Kasutera” in Japanese romaji. It is basically a traditional Japanese sponge cake made without using any leavening ingredients (ie. baking powder etc.) nor any oils. It is always served in (almost) square slices like photographed above. Another special thing about this cake is that it is traditionally made with bread flour — not cake flour. The bread flour gives it a slightly chewy texture and honey also adds moisture to the cake which makes it very good to enjoy without serving it with cream, fruits, syrup etc. The castella was brought to Japan by the Portuguese and the Japanese eventually made it to suit their taste, making it a famous Nagasaki sweet.
The video above shows you how to bake the cake in a newspaper mould, the instructions for making the mould is here. Yes, it might sound crazy to bake something in newspaper but it works very well according to the video. To my knowledge, this cake is traditionally baked in a special wooden mould but making your own with newspaper is very affordable and easy. I have a 7″ square cake pan at home so I didn’t make my own mould with newspaper, and it just worked as well. I made a half batch of the recipe in the video and baked it in a 7″ square pan. I didn’t follow the instructions on the video exactly. I mixed in the yolks, flour and honey with my trusty stand mixer instead of by hand because I was too lazy to do it by hand.
Ingredients
- 5 Egg Yolks (room temperature)
- 4 Egg Whites (room temperature)
- 125 g Granulated Sugar
- 100 g Bread Flour (sifted)
- 15 g Turbinado Sugar (optional)
- 50 g Honey (diluted with 2–3 tbsp. hot water)
Method
- Prepare pan: line insides and bottom of pan with foil and add a piece of parchment paper onto the bottom, sprinkle with turbinado sugar.
- Preheat oven to about 325 F / 160 C.
- Place egg whites in mixing bowl and mix with a mixer on high speed for about 30 seconds and start adding sugar in 2 — 3 times. Beat until firm peaks are formed.
- Add yolks one by one and mix on low speed until well combined.
- Add sifted bread flour and mix on low speed until just combined.
- Add honey and hot water mixture and mix on low speed until mixed.
- Pour batter through a sieve into cake pan, use a spatula or whisk to help the thick batter go through the sieve.
- Tap pan on the counter to remove any large bubbles in the batter.
- Bake in preheated oven for about 60 minutes or until golden brown on top — check with a skewer to see if cake is ready.
- If ready, take out of oven (with oven mitts) and drop the pan on the counter from about a foot in height to prevent shrinkage.
- Cool cake. Revert cake onto a piece of parchment paper and plastic wrap, remove foil and wrap in plastic wrap until ready to serve (at least overnight) to preserve moisture in cake (leave upside down).
- Cut off edges and slice to serve!
YUM! I love this cake because it is so simple, light and delicious. So moist, delicate and rich in honey and egg flavour — perfect with a cup of Japanese tea! The turbinado sugar is optional but it almost becomes a syrup on the bottom of the cake for even more moisture. This cake is best enjoyed the day after so it becomes more moist — kind of like resting a freshly cooked piece of meat.
Note: This is not an easy recipe, if you are a baking novice, you might want to try simpler recipes before trying this one!

Hi there,
Thanks for reading my blog and your wonderful comments! I don’t have a Facebook page but I am planning to make one so feel free to follow when I do get one!

LOvely Japanese recipe! I am so amazed at how moist and soft the texture of this cake is. And to think the recipe calls for bread flour and not cake flour. I am sure I’ll be smitten by the mild and sweet flavor of honey. Thanks for the post. This is something I will try in my own kitchen.
Thanks! This is a pretty delicate cake even though it was made with bread flour. Definitely try it out!
This does truly look wonderful. Delectable and tasty! Good job!
Hi there,
Thanks for your comments and hope you enjoy reading my blog!
Looks delicious. Would love for you to share this with us over at foodepix.com.
This is wonderful! I can only imagine the delicate flavour of this cake. I’m sure I’ll be making this cake in the future. It looks yummy!!! Thanks for sharing and I look forward to receiving your recipes in my inbox
Thanks!
Love honey sponge. This looks perfect!
Thanks!
Always looking for a challenge–this recipe looks great, not to mention, it’s gorgeous. I’m really intrigued by all the directions.
I’ve made regular sponge cake before (probably one of my favorite desserts), and it definitely can be tricky to get it to the right consistency/texture and make sure it doesn’t collapse.
Thanks for sharing! Your site is beautiful.
You’re welcome! I think this recipe is pretty good so try it sometime!
this looks awesome. i remember eating these as a kid when ever id leave the asian market with my grandma. id love to make it,especially for her. but im not sure how to use the Metrics. is there any way you can convert it to the US Measuring?
Hi Jess,
Thanks for reading my blog! This recipe was taken directly from the Japanese video and they are used to doing everything in metrics. There are probably websites that can convert the weight (metrics) of the ingredients to US measurements online.
Hope this helps!
Honey and fluffy cakes. I cannot resist. I can only hope mine will turn out as gorgeous as yours. P:
…but could you elaborate on point 10? Are you saying we should flip the pan over and drop the cake from a certain height?
Hi there,
Thanks for your question. For #10 on the instructions, after you take out your freshly baked cake in the pan and drop it right side up and leave it to cool. After the cake has cooled down, take the cake out and wrap it and leave it upside down so the top becomes flat. Hope this helps
Hello!
I tried your recipe today, the castella has a great taste! However I think I might have missed something in the process (I’m not a beginner but not an expert either! I’m 19 and I bake when I don’t want to write my papers…). First, the parchment paper has stuck to the cake and when I peeled it off, it took a bit of the brown part of the cake (so it won’t look as pretty as in your pictures), and second, I couldn’t pass the batter through the sieve because it was too thick –maybe I should have tried harder? Also, I think my pan was too large since the cake doesn’t look as thick as in the picture.
It was the first time I had baked a castella, so I know I need practice. But I wanted to be sure that I actually made mistake, so I won’t make them next time!
Hi Nana,
Thanks for your questions! Little things make a difference when it comes to baking, like different ovens, baking times, baking pans, ingredients etc etc.
The parchment paper didn’t come off cleanly when I peeled it off so it shouldn’t be a big problem. (Was the cake cool when you peeled it off? or was the bottom browned enough, if not maybe leave it in the oven for a bit longer?) If uneven browning on the top and bottom seem to be a problem — for example, sometimes if it browns too much on the top and not enough on the bottom, I would use a piece of foil with the shiny side on top to prevent the top from burning and continue baking the cake until it is ready.
The batter is pretty thick so you will have to use spatula or a whisk to work it through — but my sieve wasn’t a fine one, if you used a very fine sieve that might be the problem.
Hope this helps!
PS: Can I ask what kind of baking pan you are using — size and material?

Your cake looks yummy!
I made the castella cake yesterday. It was hard to wait until today to eat it. It was spongy and very yummy! Thanks so much for sharing the instructions.
You’re welcome, glad to hear that the recipe was a success for you!
I’ve never had this cake before, but really want to try this. Thanks for posting the instructions, and the video really helps as well. I’m not sure if I’m ambitious enough to make a newspaper mould although it is very cool! Just out of curiosity, do you know why on the video, the chef folded the batter using the whisk vs. the spatula? She didn’t seem to be too gentle on folding the batter either, but I guess the batter is really thick with all of the beat egg whites so it doesn’t really matter…(?)
Thanks again for posting and for sharing!
Hi there,
That’s a good question. When I made it I didn’t fold in the flour with a spatula, instead I used whisk attachment on my stand mixer to mix it in and it turned out great. I think whipping the egg whites and using bread flour give the cake a very good and strong structure so it would be actually be easier to get the flour all mixed in thoroughly using a whisk than a spatula. The cake is not that difficult to make, you should try it!
Betty
I’ve never eaten this cake, and I’ve never really liked sponge cakes. But I baked this one and it was a HIT !!
Thank you so much for this recipe and your detailed tutorial
I invite you to see my post (which includes a credit and link to your post)

Again — thank you!:)
Thanks, Winnie. Glad the recipe worked so well for you.
Can i use normal plain flour for this?
Hi Jun,
I haven’t tried with “plain” or “all purpose” flour. The difference the bread flour makes is that there is a high level of gluten in it that gives the cake a good structure and texture. I think it is safe to use “all purpose” flour which has a medium level of gluten in it but I wouldn’t use cake flour. However, if you want to achieve the unique castella texture, I strongly recommend using bread flour. Besides, you can bake bread with it

Your steps and photos are very detailed and I’ve followed them but my cake still failed, it sinks in the middle when I removed from the oven. What could have went wrong?
Thank you.
Hi Serene,
I am guessing the following possible errors:
– Not incorporating enough air into the eggs and sugar — mixture hasn’t reached the “ribbon” stage.
– Over-mixing the batter after adding bread flour — the batter should just be mixed until incorporated to prevent too much deflation.
– Cake wasn’t cooked thoroughly in the middle — best to test before taking out of the oven.
– Did you drop the cake pan on the counter after taking it out of the oven (as written in recipe)? It prevents shrinking and sinking.
I haven’t see the outcome of your cake or the process of how you made it, so this is just my basic diagnosis, hope it helps!
I am not sure if you have seen the video linked in the post — it might help you because it shows you step-by-step stages of the batter.

Hi Betty,
Thanks for your reply I will definitely try it again and take note all the points you mentioned.
