FAQ
Can I make this cake without a stand mixer?
Yes, use a hand mixer or whisk vigorously by hand, though the whipping time for eggs and sugar may take longer to achieve proper thickness and volume.
What if I don't have three 8-inch pans?
Bake in two 9-inch pans and adjust baking time to 30-35 minutes. You'll have two thicker layers instead of three.
How long will this cake keep?
Covered in refrigerator for up to 3 days. The flavors actually improve after the first day as components meld together.
