Jiggly And Fluffy Castella Cake Recipe


A Japanese store selling castella cake recently opened near my neighborhood. I’ve tried castella cake, pronounced as kasutera in Japanese, before when I took a trip to Japan. It was one the fluffiest cakes I’ve tried! This jiggly cake has a mild flavor and is as light and airy as a cloud. It almost melts in your mouth!

It’s perfect for tea time or dessert so I tried making it at home. But before anything else, what is a castella cake? It’s a fluffy cake made of bread four, eggs, honey, and sugar. It’s similar to a regular western sponge cake. But this one is more bouncy, moist, and delicate due to the fact that there is no butter or leavening agent used. It simply relies on the whipped eggs to make it pillowy in texture.

Taiwan also has its own version of castella cake. However, a Taiwanese castella cake uses baking powder, cake flour or regular all-purpose flour, and butter. Both versions will still yield that fluffy and delicate texture. But since I love honey on my cakes, I opted for the Japanese honey cake instead!

Here are the ingredients I used for my light, pillowy, and jiggly castella cake recipe:

  • Eggs – It is crucial to beat the eggs until thick and pale yellow. You must incorporate air into them to expand while baking and make the castella cake fluffy.
  • Bread flour – To make the signature bouncy texture of the castella cake. Compared to other flours, bread flour contains the highest amount of gluten. This will hold the delicate cake together.
  • Granulated sugar – To add a touch of sweetness to it.
  • Honey – It adds a mild sweet taste and aroma, and makes the cake moist. In addition, I finished off the cake with a mixture of honey and water.
  • Water – A tablespoon of water is enough to loosen the batter without making it runny.
  • Salt – A pinch of salt will enhance or bring out the flavor of the other ingredients.

Don’t underestimate this castella cake recipe. The ingredients might look simple, but the outcome is truly delightful. Sweet, jiggly, and packed full of flavor. I recommend making this ahead of time, so that you’ll have a fluffy and moist cake by the time it’s ready for munching. Make this for your family and friends to enjoy with tea or coffee!
