A light, bouncy sponge cake with a golden top and delicate sweetness—Castella cake is a traditional Japanese dessert known for its airy texture and rich flavor from honey and eggs. Perfect with tea or coffee.

Ingredients

Units Scale
  • 1/2 cup bread flour (sifted)
  • 4 large eggs (room temperature)
  • 1/2 cup granulated sugar
  • 2 tablespoons honey
  • 1 tablespoon warm water

Instructions

  1. Preheat oven to 320°F (160°C). Line a loaf pan or round cake pan with parchment paper.
  2. Warm the honey with water and mix until fully dissolved. Set aside.
  3. In a large mixing bowl, beat the eggs using a hand mixer on high speed for 1–2 minutes. Gradually add sugar and continue beating for about 7–8 minutes, until the mixture is pale and triples in volume.
  4. Add the honey mixture and mix gently.
  5. Sift in the flour gradually in three additions, folding carefully with a spatula each time to avoid deflating the batter.
  6. Pour the batter into the prepared pan, tap gently to remove air bubbles.
  7. Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
  8. Let cool slightly, then remove from pan and cool completely before slicing. For best results, wrap and refrigerate overnight before serving.

Notes

  • Use bread flour for the traditional slightly chewy texture.
  • Do not overmix once the flour is added to maintain volume.
  • For a smoother top, trim the surface slightly before serving.
  • Chilling overnight helps develop the cake’s flavor and texture.
