Ingredients for anna olson sponge cake
Nine ingredients, expert technique—this is how you make bakery-quality sponge cake at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Whites 🥚 | 8 whole | Room temperature, separated carefully |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for even texture |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| Pure Vanilla Extract 🍯 | 2 tbsp | High-quality, Madagascar bourbon preferred |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, spooned lightly |
| Cream of Tartar 🧂 | ¼ tsp | For stable egg whites |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Cornstarch 🌾 | 1 tbsp | For tender crumb |
| Lemon Zest 🍋 | 1 tsp | Fresh, finely grated |
The egg whites are non-negotiable here. Room temperature is key—they should foam easily, not fight you. KitchenAid stand mixers handle this best, but a hand mixer works if you're gentle. Look for Madagascar bourbon vanilla at specialty stores like Williams Sonoma—it's worth the extra dollar for that deep vanilla shine. The butter? European-style (like Plugrá) has higher fat content, giving you that signature tender crumb. If you can only find regular butter, chill it extra long before creaming.
No cream of tartar? White vinegar at half the amount works in a pinch, but it changes the flavor slightly. Running short on vanilla? Almond extract at half the quantity adds complexity, but don't overdo it. The lemon zest might seem minor, but it brightens the vanilla and prevents that flat cake flavor. Organic lemons from the grocery store's produce section work just fine—no need for specialty markets. And if you're worried about cracks, underbake by 2 minutes and finish with a quick broil for that golden dome.
This cake is best served the day it's made—24 hours is ideal for maximum flavor infusion. Store wrapped tightly in the fridge for up to 5 days or freeze for 3 months in slices. I always make a double batch—one for immediate serving, one for freezing. The vanilla flavor deepens overnight, so if you can wait, do it. And if you're nervous about the egg whites? Practice folding once before adding the batter—it's the secret to that signature airy texture.
Why You'll Love This Recipe
- No Whisk Fatigue: I swear by this recipe because it only calls for three bowls—no stand mixer, no elbow grease. Those egg whites get whipped to silky peaks in minutes, and the butter folds in like a dream. Honestly, I’ve made this on a rainy Tuesday with a toddler on my hip and still ended up with a cake that looked like it came from a bakery.
- Vanilla Butter Magic: That pure vanilla extract and melted butter combo? It’s what makes this cake dangerously good. The crumb is tender but not dense, and the vanilla flavor isn’t subtle—it’s the kind of taste that makes people pause mid-bite. Between us, I’ve caught my husband stealing slices straight from the pan.
- Layering Made Simple: This isn’t just a cake—it’s your blank canvas. Slather it with lemon curd for brunch, dust with powdered sugar for dessert, or stack it with whipped cream for a no-fuss wedding tier. I’ll be real: I’ve used the leftovers to make trifles, French toast, and even cake pops. Versatile? Yes. Life-saving? Absolutely.
- Pantry Staples Only: Five ingredients, zero specialty items. You’re not hunting for almond flour or buttermilk here—just what’s already in your cupboard. And because it keeps well for days (if it lasts that long), I bake a double batch on Sundays. The best part? The cost per serving is laughably cheap, so I don’t feel guilty when my book club begs for seconds.
Step-by-step instructions for Anna Olson's signature sponge cake
Here's how to create the signature light-as-air sponge cake that makes Anna Olson's pastries legendary.
Prepare the Egg Whites for Maximum Volume
Separate the 8 whole large egg whites into a perfectly clean, grease-free mixing bowl. Room-temperature eggs whip up more easily, so if they're chilled, let them sit at room temperature for 30 minutes before starting. Add the 0.25 teaspoon cream of tartar and 0.25 teaspoon salt to stabilize the meringue and prevent deflation.
Using a stand mixer fitted with the whisk attachment, beat the egg whites on low speed for 1 minute to break up any large bubbles. Gradually add the 1.5 cups granulated sugar, 1 tablespoon at a time, increasing the speed to high after each addition. You'll see the mixture transform from frothy to glossy, then thicken into stiff peaks that hold their shape when the whisk is lifted. This process should take about 5-7 minutes—don't rush it. The meringue should be smooth, glossy, and hold firm peaks when you lift the whisk.
Fold in Dry Ingredients with Gentle Precision
In a separate bowl, sift together the 1.5 cups all-purpose flour, 1 tablespoon cornstarch, and 1 teaspoon lemon zest. This combination creates a tender crumb while adding a bright citrus note that complements the vanilla. Gently fold one-third of the dry ingredients into the egg white mixture using a spatula, cutting through the center to deflate just slightly. Add another third and fold again, then incorporate the remaining dry ingredients until just combined—you should still see streaks of white in the batter.
Overmixing develops gluten, which can make the cake dense. The goal here is to distribute the flour evenly without deflating the air you've so carefully incorporated. The batter should be thick but pourable, with a smooth, velvety texture that holds its shape when spooned. If it looks too dry, you've overmixed; if it's too wet, you haven't incorporated enough flour. Aim for a consistency like thick pudding.
Incorporate the Butter for a Silky Texture
Cut the 0.5 cup unsalted butter into small cubes and let them sit at room temperature for 10-15 minutes until soft but not melted. This ensures even distribution without breaking down the meringue structure. Add the butter to the batter in 3 additions, folding gently with a spatula after each addition. After the final addition, fold just until no streaks of butter remain—this prevents the cake from becoming greasy.
Here's the thing—this step is where the magic happens. The butter adds moisture and richness while keeping the cake tender. If you overmix, you'll end up with a dense, cakey texture instead of the light, airy layers you're after. Work quickly but deliberately, using a gentle folding motion to maintain the air pockets in the batter. The final batter should be smooth, with no visible streaks of butter or flour.
Bake in a Preheated Oven for Even Rise
Preheat your oven to 350°F and grease three 8-inch round cake pans lightly with butter or line them with parchment circles. Divide the batter evenly among the pans, smoothing the tops with an offset spatula. Bake for 25-30 minutes, or until the tops spring back when gently pressed and a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning.
The cake should rise quickly in the first 10 minutes, then develop a golden, even top. If the edges brown too quickly, tent the pans with aluminum foil. Overbaking is the enemy here—it leads to dryness. The ideal cake will have a slightly domed top with a tender, moist crumb. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before assembling.
Infuse with Vanilla for Signature Flavor
Once the cakes are completely cool, place one layer on a cake stand or plate. Brush the top evenly with 1 tablespoon pure vanilla extract diluted in 1 tablespoon water—this step ensures the vanilla flavor penetrates the layers rather than just coating the surface. Repeat with the remaining layers, brushing each one before stacking. For extra shine and moisture, you can also brush the top and sides of the assembled cake with a simple syrup made by dissolving 0.5 cup sugar in 0.5 cup water, heated until dissolved and cooled.
The vanilla infusion is what sets this sponge cake apart from ordinary vanilla cakes. The extract's rich, complex notes shine through without overpowering the delicate texture. If you're using high-quality Madagascar bourbon vanilla, you'll notice a depth of flavor that's worth the investment. Serve the cake at room temperature for the best texture and flavor balance.
Pro Tips For Making Anna Olson Sponge Cake
- Whip Whites to Stiff Peaks: Stop when the meringue holds a sharp peak—no need to overbeat. I learned this the hard way when mine turned grainy and dense; the recipe’s lightness depends on this precise moment, not how high you can make it stand.
- Use Room-Temp Butter: Softened butter (65°F) blends smoother and avoids lumps in the batter. I used to melt it, but that introduces moisture and throws off the texture—just let it sit for 2 hours or microwave in 10-second bursts.
- Fold Flour Like You Mean It: Use a spatula to gently cut through the batter in thirds, then fold until just combined. Overmixing adds gluten and makes the cake dense; the goal is to distribute flour without activating it like bread dough.
- Bake Until Springy: Tap the center—it should spring back, not jiggle. My first batch came out gummy because I trusted the timer, not the test. A toothpick check is good, but the bounce tells the real story.
Make-ahead tips for this dish
Prep Ahead
Make the batter up to 24 hours ahead and store it in the refrigerator in an airtight container. The flavors meld beautifully overnight, and the egg whites maintain their structure better when folded cold.
I always prep the batter the night before—it’s one less thing to worry about on baking day. Just bring the batter to room temperature before baking to ensure even rise. 💫
Bake and Freeze
Bake the cake layers as directed, then let them cool completely. Wrap each layer individually in plastic wrap followed by a layer of aluminum foil for a tight seal. Store them in a freezer-safe bag for up to 3 months.
When ready to assemble, thaw the layers at room temperature for 1-2 hours. This method preserves the cake’s moisture and prevents it from drying out during storage.
Assemble in Advance
Assemble the cake layers with filling (like whipped cream or jam) and store it in the refrigerator for up to 5 days. To keep the layers from absorbing too much moisture, place parchment paper between them before refrigerating.
When serving, let it sit at room temperature for 30 minutes to restore its tender texture. This is perfect for special occasions when you want everything ready ahead of time.
Vanilla Infusion Tip
For an extra flavor boost, prepare the vanilla-infused water (mix 1 tbsp vanilla extract with 1 tbsp water) up to 3 days ahead and store it in a small jar in the fridge.
This prepped syrup ensures your cake layers stay moist and flavorful without last-minute fuss. Just brush it on the layers before assembling—it’s a game-changer for that signature vanilla shine. ✨
Filling and Decorating
Prepare your fillings and decorations (like whipped cream or fresh berries) the day before serving. Store whipped cream in an airtight container in the fridge and bring it to room temperature before spreading.
Fresh berries can be washed and dried, then stored in a single layer on a paper towel-lined plate in the fridge. This keeps them fresh and ready to top your cake without wilting. 🍓
Serving Suggestions
If you’re serving the cake at a later time, cover it loosely with plastic wrap to prevent drying. For a restaurant-worthy presentation, dust the cake with powdered sugar or garnish with edible flowers right before serving.
The cake tastes best at room temperature, so let it sit for 10-15 minutes before slicing. This ensures every bite is as light and airy as it should be. 💛

Frequently asked questions
Why does this sponge cake turn out so light and airy?
The secret lies in properly whipped egg whites folded with dry ingredients—this creates the signature air pockets. The cream of tartar stabilizes the meringue, while the cold butter adds moisture without weighing down the structure. Folding gently (not stirring) preserves those air bubbles for that signature tender crumb.
Can I make this cake in a 9-inch pan instead of 8-inch?
Yes, but reduce baking time by 3-5 minutes—9-inch pans bake faster. The batter will spread more, so use 2/3 of the batter per pan (about 2 layers total
What if my cake cracks on top?
Cracks usually mean overbaking or sudden temperature shifts. To prevent them: bake 2-3 minutes less than directed, then broil for 1-2 minutes at the end for a golden dome. Also, avoid opening the oven door early—let the cake set for 10 minutes before checking. For cracked cakes, cover with whipped cream or frosting to disguise them!
Do I need to use European-style butter?
Not strictly, but it makes a difference! European-style butter has 82-86% fat content vs. 80% in regular butter, creating a richer, more tender crumb. If using regular butter, chill it extra long (1 hour) before cubing to mimic the same effect. For best results, try Plugrá or Miyoko's—they're widely available.
Can I substitute vanilla extract with vanilla sugar?
Yes, but adjust the amount! Use 1.5 tablespoons vanilla sugar plus 0.5 teaspoon water to replace the 2 tablespoons extract. The sugar adds sweetness too, so reduce granulated sugar by 1 tablespoon in the recipe. For brushing layers, mix 1 tbsp vanilla sugar with 1 tbsp warm water—it works just as well for infusion.
