Ingredients Needed

To make this Fluffy Castella Sponge Cake, you’ll need:

  • 4 large eggs
  • 100g (1/2 cup) granulated sugar
  • 100g (3/4 cup) cake flour (or all-purpose flour)
  • 1 tablespoon honey
  • 2 tablespoons milk
  • 1 tablespoon unsalted butter (melted)
  • Pinch of salt

Optional Substitutions:

  • For a dairy-free version, use almond milk and dairy-free butter.
  • For a gluten-free option, substitute the cake flour with a gluten-free flour blend.

Step-by-Step Instructions

  1. Prepare Your Pan: Preheat the oven to 160°C (320°F). Line a loaf pan with parchment paper, ensuring there’s enough paper hanging over the sides for easy removal later.
  2. Beat the Eggs: In a large bowl, whisk the eggs and sugar together until the mixture becomes thick and pale, which will take about 5-7 minutes. This step is crucial for the light texture of the cake.
  3. Combine Wet Ingredients: Gently heat the milk, honey, and melted butter in a separate bowl until warm. Slowly add the warm mixture to the egg-sugar blend, stirring gently.
  4. Sift the Dry Ingredients: In another bowl, sift the cake flour and salt. This ensures that the flour is light and free of lumps. Gradually fold the sifted flour into the wet mixture, making sure not to deflate the batter.
  5. Bake the Cake: Pour the batter into the prepared pan. Tap the pan gently on the counter to remove any air bubbles. Bake for 40-45 minutes, or until a skewer inserted into the center comes out clean.
  6. Cool Down: Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Recipe Tips & Variations

  • Avoid Overmixing: When folding in the flour, be gentle to avoid deflating the batter. The air trapped in the batter is what makes this cake so fluffy.
  • Honey Substitute: If you don’t have honey on hand, you can use maple syrup or agave for a slightly different flavor.
  • Flavor Variations: Want to add a twist to your cake? Try adding a teaspoon of vanilla extract or matcha powder to the batter.

How to Store & Reheat

Store any leftover Fluffy Castella Sponge Cake in an airtight container at room temperature for up to 2-3 days. To keep it fresh longer, you can refrigerate it, but it’s best served at room temperature. If you’d like to reheat it, simply warm it in the microwave for 10-15 seconds.
