Fluffy Cocoa Sponge Cake Pan di Spagna
Pan di Spagna al cacao is an Italian sponge cake renowned for its light, airy crumb and rich cocoa flavor. This version prioritizes the precise whipping technique that defines the cake's signature texture: eggs beaten for at least 15 minutes create the structure that keeps it tender and pillowy. The combination of unsweetened cocoa powder and fine flour delivers deep chocolate notes without heaviness. Best made by bakers comfortable with meringue and folding methods. Serve as a standalone cake with coffee, or use as a base for layered desserts at celebrations like birthdays, anniversaries, or weddings. What sets this approach apart is the emphasis on parchment paper lining the pan to ensure a perfect, unblemished finish ideal for showcase occasions.

- 4 tbsp unsweetened cocoa powder
Instructions
- 1
Preheat oven to 350°F in static mode.
- 2
Prepare an 18-7.75" cake pan with high sides. Lightly grease, then line the bottom with parchment paper cut to fit. Line the sides by overlapping parchment rectangles and extending above the rim.
- 3
Separate eggs, ensuring they are at room temperature.
- 4
Whip egg whites until stiff peaks form. Add sugar gradually, tablespoon by tablespoon, until meringue is very stiff and glossy.
- 5
Add yolks one at a time without stopping the mixer, ensuring each is fully incorporated before adding the next. Continue beating for at least 15 minutes total.
- 6
Sift flour and cocoa powder together carefully.
- 7
Fold dry ingredients into the egg mixture gently with a soft spatula, working from bottom to top, until just combined and not deflated.
- 8
Pour batter into prepared pan. Tap pan lightly to level.
- 9
Bake for 35-40 minutes. Do not open the oven for the first 20 minutes. Test doneness with a toothpick.

Cool completely before unmolding and removing parchment.
Tips
Room-temperature eggs whip to greater volume and stability. Cold eggs take longer to incorporate fully and yield less lift. Remove from refrigerator 30 minutes before starting.
Sifting flour and cocoa together prevents cocoa streaks and lumps. Do this over a bowl, then fold in with a rubber spatula using broad strokes from the bottom up to preserve air.
Parchment lining prevents sticking and helps unmold an unblemished cake, especially important for tiered desserts or occasions where appearance matters.
Good to Know
Keep in an airtight container at room temperature for up to 3 days. Store in the refrigerator for up to 5 days. Do not freeze baked cake as the crumb becomes dense upon thawing.
Prepare parchment-lined pan up to 1 hour ahead. Cake batter is best baked immediately after folding flour and cocoa in. Baked cake can cool completely (3-4 hours) before filling or frosting.
Serve at room temperature with espresso, dusted with powdered sugar, or split and filled with mascarpone cream, jam, or buttercream.
Common Mistakes
Do not open the oven during the first 20 minutes to avoid sudden temperature drops that collapse the structure.
Do not overwork or overmix when folding dry ingredients to avoid deflating the whipped eggs and losing lift.
Do not use cold eggs from the refrigerator; they will not whip to full volume and the final cake will be dense.

Full guide →FAQ
Can I make this cake without separating eggs?
No. Separated eggs and whipped whites are essential to the structure and rise of this cake. The foam created by whipping incorporates air that creates the sponge texture. Whole-egg methods produce denser cakes.
What if I don't have cocoa powder?
You can omit it and increase flour to 130g for a plain vanilla sponge. Alternatively, substitute melted chocolate, but reduce flour slightly. The cake will taste different and be heavier due to fat content in chocolate.
Can I freeze this cake?
No. Freezing causes the delicate crumb to compress and become dense upon thawing. Instead, split and fill the cake, wrap tightly, and refrigerate for up to 5 days. Unfilled cake is best eaten fresh.
What if my cake sinks in the middle?
This indicates underbaking or oven temperature inconsistency. Ensure your oven is properly calibrated. Check with a toothpick; it should show just a few moist crumbs, not wet batter. Overbaking dries it out instead.
