Approximate baking times:Two 6-inch pans: about 27 to 30 minutes
Three 6-inch pans: about 18 minutes
Four 6-inch pans: 15 to 16 minutes
9×13 inch pan: about 18 minutes
Make ahead and freeze:
Sponge cakes freeze amazingly well if frozen the same day. Wait until completely cool then store in an airtight, freezer-safe container to avoid frost. Thaw in the fridge overnight.
Troubleshooting deflated sponge cake:The most likely reason is due to improperly beating the egg whites. It’s very easy to over or under-beat egg whites. Over-beaten egg whites will look grainy and lumpy.
Old or expired baking powder. Check the dates on your ingredients.
Baking temperatures can also affect the rise of sponge cakes. It’s important not to open the oven as the temperature drop can cause the sponge cake to collapse and deflate. Use an oven thermometer or calibrate your oven if not done recently.
