Ingredients for anna olson sponge cake
Six ingredients, flawless technique—this is where vanilla magic happens in your kitchen.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Room temperature, European style preferred |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smoother texture |
| Large Eggs 🥚 | 6 whole | Room temperature, separated carefully |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, spooned lightly |
| Pure Vanilla Extract 🌿 | 1 ½ tbsp | High-quality Madagascar bourbon preferred |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain preferred |
The butter makes or breaks this cake. European-style unsalted butter has higher fat content, which creates that signature tender crumb. I always grab Plugrá or President from specialty stores—they're worth the splurge for this recipe. Room temperature is critical: press the butter between two sheets of parchment and let it sit for 1-2 hours at room temp. If it's too soft, chill it 15 minutes. The sugar? Superfine dissolves more easily, but regular granulated works if you pulse it in a food processor first. For flour, King Arthur or Gold Medal are my go-tos—they have consistent protein levels that give reliable structure.
No vanilla extract? Vanilla bean paste works beautifully—just use half the amount and scrape out every last bit. Short on eggs? This isn't a recipe to substitute—egg whites create the signature airy texture, and yolks bind the delicate crumb. The salt is non-negotiable—Diamond Crystal measures differently than Morton, so use 1/4 tsp if you have it. For gluten-free adaptation, swap the all-purpose flour for 1:1 gluten-free baking flour blend—like Bob's Red Mill—plus 1/2 tsp xanthan gum. The vanilla extract? Bourbon-aged Madagascar has the most complex flavor profile, but pure vanilla will work in a pinch.
Store the dry ingredients—flour, sugar, salt—in airtight containers for 6 months at room temperature. Butter keeps 3 months refrigerated or 6 months frozen. Eggs should be used within 1 week of purchase. Once baked, the cake layers stay fresh 3 days wrapped tightly at room temperature or 1 week refrigerated. For long-term storage, freeze layers between parchment paper for up to 3 months. The vanilla extract? It lasts indefinitely—just keep it in a cool, dark place.

Step-by-step instructions for anna Olson's signature sponge cake
Mastering this recipe delivers ethereal layers with a whisper-light texture and subtle vanilla depth.
Prepare Ingredients for Optimal Texture
Begin by separating the 6 whole large eggs, placing yolks in one bowl and whites in another. Let both sit at room temperature for 30 minutes—this ensures even whipping and maximum volume. While they temper, sift the 1.5 cups all-purpose flour into a medium bowl and set aside.
In a separate bowl, measure out the 1 cup unsalted butter and 1.5 cups granulated sugar. The butter should be completely softened but not melted—press your finger into it; it should leave a slight indentation. This precise consistency creates the cake's signature tenderness. Add the 1.5 tablespoons pure vanilla extract and 0.25 teaspoon diamond crystal kosher salt to the butter-sugar mixture.
Whip Egg Yolks and Butter Mixture
Using a stand mixer fitted with the paddle attachment, combine the egg yolks and butter-sugar mixture on medium speed for 2 minutes. This initial blending ensures even distribution of the butter's richness. Increase the speed to high and whip for an additional 3-4 minutes until the mixture lightens in color and triples in volume.
Here's the critical moment: the mixture should be pale, thick, and ribbon-like when the beaters are lifted. If it's still grainy, whip for another 30 seconds. This yolk-butter emulsion is the foundation of the cake's signature airiness—don't rush this step or you'll compromise the structure.
Fold in Flour and Prepare Egg Whites
With the mixer on low speed, gradually add the sifted 1.5 cups all-purpose flour to the yolk mixture, mixing just until combined. Be gentle—overmixing develops gluten and creates a dense cake. Remove the bowl from the mixer and set aside.
In a separate, spotlessly clean bowl, whip the egg whites on medium speed until soft peaks form. Gradually add the 1.5 cups granulated sugar (use superfine if available) while whipping on high speed for 3-4 minutes until the meringue is glossy and holds stiff peaks. This sugar incorporation creates the cake's signature stability and sweetness balance.
Combine Mixtures with Perfect Folding Technique
Using a spatula, gently fold one-third of the egg white meringue into the yolk mixture to lighten it. Then, add the remaining meringue in two additions, folding just until combined. This layering technique prevents deflation while maintaining maximum air incorporation. The batter should be smooth, thick, and hold its shape when lifted with the spatula.
Divide the batter evenly among three 8-inch round cake pans lined with parchment circles. Tap the pans gently on the counter to remove air bubbles. The batter should fill the pans to the top—this creates the signature domed shape when baked.
Bake with Precision for Even Rise
Preheat your oven to 350°F and place the pans on the middle rack. Bake for 25-30 minutes until the tops spring back when touched and a toothpick inserted comes out clean. The edges should be golden while the centers remain pale—this indicates proper doneness without overbaking.
Remove the cakes immediately and let them cool in the pans for 10 minutes before transferring to a wire rack. This brief cooling period prevents collapse while allowing the cakes to set. For best results, bake only one layer at a time to maintain consistent oven temperature.
Pro Tips For Making Anna Olson Sponge Cake
- STOP OVERBEATING EGGS: I learned this the hard way—whipping eggs for this cake until they’re too stiff (like meringue) kills the air pockets. Aim for soft peaks that hold shape but still glide like ribbon when you lift the whisk. The cake needs that lightness, not a rubbery texture.
- USE ROOM-TEMP BUTTER: Cold butter from the fridge will make your cake dense and greasy. Let that butter sit out for 1-2 hours until it’s soft enough to press a fingerprint into it—no melting, just pliable. This ensures even distribution and that signature tender crumb.
- DON’T OVERMIX THE BATTER: The moment you fold in the flour, stop. Just until combined—lumps are fine, but overmixing develops gluten and turns your delicate sponge into a cake brick. Use a spatula to gently fold in thirds, and resist the urge to stir like you’re making pancakes.
- BAKE UNTIL COOL TOUCH: The recipe says "golden brown," but that’s not always enough. Press a finger into the center—it should spring back and feel cool to the touch. If it’s warm, it’s still cooking. Overbaking dries out the cake; underbaking leaves it gummy. (Yes, even if you’re impatient like me.)
Regional styles of anna olson sponge cake
Swedish Classic
Anna Olson’s sponge cake has deep roots in Swedish baking traditions, where light, airy cakes are staples for celebrations. The original Swedish version often includes cardamom (½ tsp ground) for warmth, replacing vanilla.
I’ve baked this version using Swedish butter (like Lakris & Pepparkakor) and cardamom-infused sugar—the floral notes elevate the vanilla depth. Serve with lingonberry jam and whipped cream for an authentic touch. 🌱
French Adaptation
In France, this cake transforms into a génoise, a classic sponge used for layering with pastry cream. The key difference? No butter—just egg yolks, sugar, and flour.
For a hybrid version, replace half the butter with egg yolks (3 extra yolks) and fold in 1 tbsp cornstarch for stability. French bakers often dust the finished cake with powdered sugar and add a raspberry coulis for elegance. 🍷
Italian Twist
Southern Italian bakers lighten the batter with orange zest (1 tsp) and amaretto (1 tbsp), replacing vanilla. The result? A citrusy, nutty depth that pairs perfectly with mascarpone frosting or lemon curd.
I’ve tested this version with Italian 00 flour (1.25 cups) for a slightly denser but more flavorful crumb. Garnish with toasted almonds for texture contrast. 🍊
Japanese Lightness
Japanese sponge cakes focus on maximum airiness, often using egg whites whipped with a touch of cream of tartar (¼ tsp) for stability. For this adaptation, replace vanilla with matcha powder (1 tsp) and fold in 1 tbsp honey for sweetness.
Bake at 325°F for 35 minutes—the lower temp prevents overbrowning while maximizing rise. Serve with red bean paste or white chocolate ganache. ✨
Modern Gluten-Free
For a contemporary twist, swap all-purpose flour for 1.5 cups gluten-free 1:1 baking flour (like King Arthur) plus ½ tsp xanthan gum. Add 1 extra egg white to compensate for reduced structure.
I’ve found almond flour (½ cup) works too—just reduce sugar to 1.25 cups for balance. The texture stays tender, though slightly denser. Perfect for dietary needs without sacrificing flavor. 💪

Frequently asked questions
Why does Anna Olson's sponge cake need to be baked in three layers?
Baking in three 8-inch layers creates the signature domed shape and ensures even baking. Each thin layer cooks faster and rises more uniformly than a single thick layer, preventing overbrowning while maintaining that signature light-as-air texture. The layers can be stacked or served individually—perfect for both formal cakes and elegant desserts!
Can I substitute vanilla extract with vanilla sugar?
Yes, but adjust carefully! Replace 1.5 tbsp vanilla extract with 1 tbsp vanilla sugar (plus 0.5 tbsp water to maintain moisture). The flavor will be slightly different—vanilla sugar has a more concentrated, sweet vanilla taste. For best results, use high-quality vanilla sugar and add it with the dry ingredients.
What's the secret to preventing cracks in the cake?
Cracks usually happen from overmixing or opening the oven too soon. To avoid them: fold the meringue gently (just until combined), don't overfill the pans, and bake at 350°F for exactly 25-30 minutes. Let the cakes cool in the pans for 10 minutes before removing—they'll set properly and minimize cracks.
How do I store leftover sponge cake layers?
Wrap each layer tightly in plastic wrap and store at room temperature for 3 days or refrigerate for 1 week. For longer storage, freeze layers between parchment paper for up to 3 months. Thaw overnight in the fridge before assembling. The texture stays perfect when properly stored!
Can I make this cake without a stand mixer?
Whip egg whites by hand in a spotless bowl using a balloon whisk until stiff peaks form. For the yolks, use a hand mixer or whisk vigorously for 5-7 minutes until pale and thick. The key is patience—just work in short bursts to avoid overheating. The cake will still turn out light and tender!
