  • Difficulty: Intermediate
  • Prep Time: 20 minutes
  • Cooking Time: 50 minutes
  • Serving: 8-10
  • Yield: 1 cake
  • Calories: Approximately 200 calories per serving


  • 6 large eggs
  • 1 cup granulated sugar (200g)
  • 1 cup cake flour (120g)
  • 2 tablespoons honey (30g)
  • 2 tablespoons warm water (30ml)
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • Powdered sugar for dusting


  • 9×5-inch (23x13cm) loaf pan
  • Electric mixer or stand mixer
  • Mixing bowls
  • Whisk or spatula
  • Parchment paper

Step-by-Step Guide:

Step 1: Preheat your oven to 320°F (160°C). Line the bottom and sides of the loaf pan with parchment paper, leaving an overhang for easy removal later.

Step 2: In a large mixing bowl, crack the eggs and add the granulated sugar. Using an electric mixer or stand mixer, beat the eggs and sugar on medium-high speed for about 10-12 minutes, or until the mixture becomes thick, pale, and triples in volume.

Step 3: Sift the cake flour into the egg mixture in three batches, gently folding it in with a whisk or spatula after each addition. Be careful not to overmix; you want to maintain the airy texture.

Step 4: In a separate small bowl, mix the honey and warm water until well combined. Add this mixture to the batter, along with the vanilla extract and salt. Gently fold everything together until fully incorporated.

Step 5: Carefully pour the batter into the prepared loaf pan, smoothing the top with a spatula. Tap the pan gently on the countertop to remove any air bubbles.

Step 6: Bake the cake in the preheated oven for approximately 50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.

Step 7: Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely.

Tips and Tricks:

  • To create a smooth and uniform texture, make sure to sift the cake flour before adding it to the batter.
  • For a touch of elegance, you can dust the top of the cake with powdered sugar or even add a drizzle of honey before serving.
  • To enhance the flavor, you can infuse the honey with citrus zest or matcha powder. Simply mix them together before adding to the batter.

Q1: Can I use a different type of flour for this recipe?
A: The classic Castella Cake is made with cake flour, which gives it its signature texture. However, if you don’t have cake flour on hand, you can make a substitute by combining all-purpose flour with cornstarch in a 1:1 ratio.

Q2: Can I add any flavorings to the cake batter?
A: Absolutely! While the traditional Castella Cake is plain, you can experiment with different flavors by adding citrus zest, matcha powder, or even a hint of almond extract to the batter.

Q3: How should I store the Castella Cake?
A: Once cooled, store the Castella Cake in an airtight container at room temperature. It is best enjoyed within 2-3 days to maintain its freshness and texture.

Q4: Can I freeze the Castella Cake?
A: Yes, you can freeze the Castella Cake for up to 6 months. Wrap it tightly in plastic wrap or place it in a freezer-safe container before freezing. Thaw it in the refrigerator overnight before serving.

Q5: Can I make mini Castella cakes instead of one large loaf?
A: Absolutely! You can pour the batter into individual mini loaf pans or even muffin tins to create smaller Castella cakes. Just make sure to adjust the baking time accordingly, as they will cook faster than a larger cake.

Q6: Can I make this recipe gluten-free?
A: Yes, you can make a gluten-free version of Castella Cake by using a gluten-free cake flour blend or a combination of gluten-free flours. Make sure to check the labels of your ingredients to ensure they are gluten-free.

Q7: Can I use a hand whisk instead of an electric mixer?
A: While an electric mixer or stand mixer makes the process easier, you can certainly use a hand whisk. Be prepared for a bit of arm workout, as it will take longer to achieve the desired volume and texture.

Q8: Can I add any toppings or fillings to the Castella Cake?
A: The Castella Cake is traditionally enjoyed plain, but you can certainly get creative with toppings and fillings. Consider adding fresh fruits, whipped cream, or even a drizzle of chocolate sauce to enhance the presentation and flavor.

Enjoy your journey into the world of Castella Cake, and may each bite bring you joy and culinary satisfaction!
