Fluffy Castella Sponge Cake – Light, Airy & Perfectly Sweet

Pour the batter into the prepared loaf pan. Tap the pan gently on the counter to release air bubbles.
Step 6: Bake Until Golden
Bake for 40–45 minutes or until the top is deep golden brown and springs back when lightly touched.
Step 7: Cool & Slice
Let cool completely in the pan before slicing. Gently pull the parchment paper to remove the cake from the pan.
💡 Pro Tips for Perfect Castella Every Time
Use Room Temperature Eggs : They whip up better and hold more air.
Don’t Skip the Cream of Tartar : It helps stabilize the egg whites for extra volume.
Sift Flour Multiple Times : Helps keep the cake light and prevents lumps.
Avoid Opening the Oven Early : Premature peeking can cause collapse.
Store Properly : Wrap tightly in plastic wrap or store in an airtight container to keep moist.
