Italian Sponge Cake (Pan di Spagna)

Pan di Spagna (Italian Sponge Cake) is a simple, airy sponge cake flavored with vanilla or lemon zest. It’s made with only 3 ingredients: eggs, sugar, and flour…no baking powder, no butter, no oil, and no dairy!

This traditional cake is used in desserts like cassata, zuccotto, zuppa inglese and tiramisù. It can be soaked with your favorite mixture and layered with cream fillings, covered with fondant, or just eaten on its own, sprinkled with powdered sugar.

The secrets to baking a perfect Pan di Spagna:

  1. Use extra large eggs (each egg should weigh approximately 70 grams/2.46 ounces). Eggs have to be at room temperature, not cold from the fridge. If they are too cold, soak them for a few minutes in a bowl of warm water.
  2. It’s better to use a low-protein flour, such as cake flour. If it’s not available in the store, you can make it at home (check out this tutorial by Joy the Baker), or use all-purpose flour.
  3. Beat the eggs and sugar for no less than 15/20 minutes. It is during this stage that air is incorporated. The eggs should turn a pale yellow.
  4. Sift the flour on top of the egg mixture, a little at a time, and fold it gently with a wooden spoon. If you pour in too much flour, it will sink to the bottom of the bowl.
  5. While the cake is baking, don’t open the oven for at least 30 minutes as this may cause the cake to deflate.
  6. When it’s ready, turn off the oven but leave the cake inside (keep the door slightly open using a wooden spoon) for 5- 10 minutes.
  7. You should cut the Italian sponge cake with a serrated knife when is cold. It’s better if you prepare it the day before, wrap it in cling film, and leave it in the fridge overnight. You can make it up to  3 days ahead!

Baking Pan:

For the sponge cake in the picture, I used a Wilton round pan 15 cm wide and 8 cm high  (6 x 3 inch). If your baking pan is not very deep, use parchment paper. Trace the bottom of the pan on a piece of parchment paper. Cut it out and line the bottom of the pan. Then line the sides of the pan with parchment paper so that the parchment paper creates a collar that sits 1 to 2-inches above the pan. Make sure that you brush some melted butter to the bottom and sides of the pan so the parchment paper sticks.

Your baking pan is a different size? Use the following ratios:

  • 12 cm (4 inches) pan: 2 eggs, 60 grams cake flour, 60 grams sugar → ½ cup + ½ tablespoon cake flour, 1/3 cup minus ½ tablespoon sugar
  • 15 cm  (6 inches) pan: 3 eggs, 90 grams cake flour, 90 grams sugar → ¾ cup + ¾ tablespoon cake flour, 1/3 cup + 2 tablespoons sugar
  • 18/20 cm  (7/8 inches) pan: 4 eggs, 120 grams cake flour, 120 grams sugar → 1 cup+1 tablespoon cake flour, ½ cup + 1 ½ tablespoon sugar
  •  23 cm ( 9 inches) pan: 5 eggs, 150 grams cake flour, 150 grams sugar → 1 1/3 cup cake flour, 3/4 cup sugar
  • 26 cm (10 inches) pan: 6 eggs, 180 grams cake flour, 180 grams sugar → 1 ½ cup + 2 tablespoons cake flour, ¾ cup + 2¼ tablespoons sugar
  • 27 cm (10 ½ inches) pan: 7 eggs, 210 grams cake flour, 210 grams sugar → 2 cups minus 2½ tablespoons cake flour, 1 cup plus ¾ tablespoon sugar
  • 28 cm (11 inches) pan: 8 eggs, 240 grams cake flour, 240 grams sugar → 2 cups plus 2½ tablespoons cake flour, 1¼ cup minus 1 tablespoon sugar
  • 30 cm  (12 inches) pan: 9 eggs, 270 grams cake flour, 270 grams sugar → 2 1/3 cups + 1 tablespoon cake flour, 1 1/3 cup sugar
  • 32 cm (12 ½ inches) pan: 10 eggs, 300 grams cake flour, 300 grams sugar → 2 ¾ cups minus 1½ tablespoon cake flour, 1 ½ cup sugar

STORAGE:

Store the cake in the refrigerator for a couple of days, until ready to use. It can also be tightly wrapped in cling film and stored in the freezer for several months. Bring it back to room temperature or unthaw overnight in the refrigerator, when needed.

Italian Sponge Cake (Pan di Spagna)

Learn how to make a traditional Italian sponge cake from scratch with only 3 ingredients: eggs, flour, and sugar!

Ingredients

For an 18-20 cm (7-8 inches) pan:

  • ½ cup + 1½ tablespoon (120 grams) granulated sugar
  • 4 extra large eggs at room temperature
  • a pinch of salt
  • 1 teaspoon grated lemon zest or vanilla extract optional
  • 1 cup + 1 tablespoon (120 grams) cake flour, sifted *you can use all-purpose flour: 120 grams=1 cup

Instructions

  • Take the eggs out of the refrigerator ahead of time as the eggs need to be at room temperature or soak them for a few minutes in a bowl of warm water.
  • Preheat the oven to 170 degrees C (338 degrees F).
  • Butter and flour (or spray with baking spray) a 20 cm (8 inches) pan. 
  • Put the eggs, sugar, salt, and lemon zest in the bowl of your stand mixer.
  • Beat the eggs until very fluffy and pale yellow (about 15/20 minutes on medium/high speed). To test that it has been beaten enough, let a small amount of batter fall into the bowl. If it remains “sitting” on top, it means that it’s ready.

  • Turn off the oven but leave the cake inside (keep the door slightly open using a wooden spoon) for 5/10 minutes so it can cool down slowly.
  • Remove the sponge cake from the oven, let it cool for 10 more minutes, then loosen around the edges with a knife, and flip it on a wire rack upside down (without the pan) to cool completely.
  • Enjoy it!
