This cake isn’t your typical sponge—it’s a luxurious hybrid that combines custard’s richness with cake’s structure. The result? A dessert that’s elegant enough for special occasions but simple enough for weeknight treats, all while keeping the signature egg-yolk decadence intact.
What you’ll achieve is a cake with perfectly set layers that slice cleanly, revealing a moist interior and a delicate golden crust.

Ingredients for 12 egg yolk cake
Twelve golden yolks, soft butter, and a whisper of vanilla—this is your golden ticket to restaurant-quality cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Yolks 🥚 | 12 whole | Room temperature for best whipping |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light batter |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smoothness |
| Unsalted Butter 🧈 | 1 ½ cups | Softened to room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar vanilla preferred |
| Whole Milk 🥛 | 1 cup | Room temperature for best incorporation |
| Baking Powder 🧂 | 1 tsp | Aluminum-free for tender crumb |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Lemon Zest 🍋 | 1 tbsp | Freshly grated for brightness |
| Cornstarch 🌾 | 2 tbsp | For extra tenderness |
| Powdered Sugar 🍚 | 1 cup | For glaze (optional) |
| Heavy Cream 🥛 | ½ cup | For glaze (optional) |
The yolks are non-negotiable here. Grab extra-large eggs if your store has them—more yolk means richer flavor. I always use Kirkland Signature eggs when I can, but any good-quality brand works. Room temperature is key: pop them in a bowl of warm water for 10 minutes if they’re straight from the fridge. The butter? Plugrá or Land O’Lakes are my go-tos, but any unsalted will do. Just make sure it’s soft enough to press with a finger but not melted. For vanilla, Madagascar bourbon is my absolute favorite—it’s got that deep, complex flavor that elevates everything.
No vanilla extract? Vanilla bean paste works great, or even a scraped vanilla bean. Short on powdered sugar for the glaze? Superfine sugar blended into a powder does the trick. The milk can be whole, 2%, or even almond milk if you’re avoiding dairy—just keep it room temp. Need to substitute cornstarch? Arrowroot powder at the same amount works just as well. The lemon zest adds that bright pop, so if you don’t have fresh lemons, bottled zest works in a pinch. Pro tip: zest the whole lemon and freeze the rest for future recipes—waste not, want not.
This batter is delicate, so don’t overmix. Once combined, it’ll keep in the fridge for up to 24 hours if you want to prep ahead. The cake itself stays moist for 3-4 days at room temperature, but I always slice it fresh for the best texture. For the glaze, mix the powdered sugar and cream right before serving—it sets fast. Store leftovers covered at room temp, but honestly, it disappears quicker than you can say ‘seconds, please!’

Step-by-step instructions for rich velvety layers without the dryness
Here’s the foolproof method for a cake so moist it’ll disappear in seconds.
👨🍳 Step 1: Whip the Egg Yolks and Sugar to Ribbon Stage
In a stand mixer fitted with the whisk attachment, combine the 12 whole Large Egg Yolks and 2 cups Granulated Sugar. Beat on medium-high speed for 5-7 minutes until the mixture turns pale yellow and forms thick, glossy ribbons when the whisk is lifted. You’ll see the mixture nearly triple in volume and leave clear streaks that hold their shape for several seconds.
This step is non-negotiable for that signature velvety texture. I like to stop occasionally and scrape down the sides with a silicone spatula—this ensures even whipping and prevents sugar from settling at the bottom. The ribbons should be thick enough to coat the back of a spoon without immediately dripping back down.
👨🍳 Step 2: Incorporate Butter and Flavorings Gradually
With the mixer running on low speed, add the 1.5 cups Unsalted Butter, 2 tsp Vanilla Extract, 1 cup Whole Milk, 1 tbsp Lemon Zest, and 2 tbsp Cornstarch in three additions. After each addition, mix until fully combined, about 30 seconds per addition. This gradual incorporation prevents the butter from breaking and keeps the batter light.
Here’s the thing—don’t rush this part. You want the butter to emulsify completely into the yolk mixture, creating that signature tender crumb. If you see any butter clumps that won’t dissolve, warm the mixture gently over a double boiler for 10-15 seconds while mixing on low. The batter should be smooth, thick, and slightly shiny by the end of this step.
👨🍳 Step 3: Fold in Dry Ingredients Gently
In a separate bowl, whisk together the 2.5 cups All-Purpose Flour, 1 tsp Baking Powder, and 0.5 tsp Salt. Sift the mixture directly into the yolk mixture and fold together using a silicone spatula. Start with a few strokes from the bottom, then gently fold from the top to incorporate the flour without deflating the batter. You’re aiming for a smooth, lump-free consistency.
I know it seems weird, but trust me—overmixing here will develop gluten and make your cake tough. Stop folding when you still see a few flour streaks. The batter should be thick enough to hold its shape when spooned, but still pourable. If it’s too stiff, add 1-2 tablespoons of the whole milk to loosen it slightly.
🔥 Step 4: Bake in Two Layers for Perfect Rise
Divide the batter evenly between two 8-inch round cake pans lined with parchment paper. Smooth the tops with a spatula. Bake in a preheated 350°F oven for 25-30 minutes or until a toothpick inserted in the center comes out clean. Rotate the pans halfway through baking for even rise.
Don’t open the oven door early—this causes the cakes to sink. You’ll know they’re done when the edges pull away slightly from the pan and the tops spring back when gently pressed. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking.
🥘 Step 5: Assemble with Cream Cheese Filling (Optional)
For the ultimate velvety experience, prepare a filling by beating 0.5 cup Heavy Cream with 4 oz softened cream cheese and 0.5 cup Powdered Sugar until smooth. Place one cooled cake layer on a plate, spread with half the filling, then top with the second layer. Dust the top and sides with remaining 0.5 cup Powdered Sugar for that classic finish.
Slice into perfect squares and watch them melt in your mouth. The secret to this cake’s success is the cornstarch—it creates that signature tender crumb while the egg yolks provide the rich, moist texture. Serve with fresh berries or a dusting of powdered sugar for the ultimate dessert experience.
Pro Tips For Making 12 Egg Yolk Cake
- Whisk Yolks Till Pale: Stop when they’re the color of wet sand—not egg wash. Over-whipping adds air but can make the cake dense later. I used to go until they thickened like glue, and the texture suffered. Aim for ribbons that hold for 2 seconds before dissolving.
- Sift Flour Twice: First pass removes lumps, but the second time cuts out hidden moisture. I learned this after a batch turned gummy—turns out, damp flour hides in plain sight. Use a fine-mesh sieve and tap the bowl’s sides to shake out every last bit.
- Butter Must Be Cold: Cut it into ½-inch cubes and let them sit in the fridge while you mix the batter. Warm butter melts into a greasy mess that won’t create those signature pockets of richness. I’ve ruined cakes by skipping this—trust me, it’s not worth the shortcut.
- Bake in Two Rounds: Split the batter into two 9-inch pans for even cooking. A single deep pan risks a raw center while the edges overbake. My first attempt in one pan left me with a sad, gummy middle. Two pans = consistent doneness every time.
Make-ahead tips for this recipe
Batter Prep Ahead
Mix the batter up to 24 hours in advance and store it in an airtight container in the fridge. The flavors meld beautifully overnight, and the cornstarch helps prevent any separation. When ready to bake, let the batter sit at room temperature for 30 minutes before dividing into pans—this ensures even baking and prevents cracks. I always label my containers with the date to track freshness. 💛
Layered Storage
Bake the cake layers as directed, then cool completely before storing. Wrap each layer individually in plastic wrap and place them in a single-layer stack inside a ziplock freezer bag. This protects against drying and keeps them fresh for 3-4 days at room temperature or 1 month in the freezer. Thaw overnight in the fridge before assembling.
Filling Prep
Make the cream cheese filling a day ahead and store it in an airtight container in the fridge. The flavors deepen, and it becomes even smoother. When ready to assemble, let the filling sit at room temperature for 15 minutes before spreading—this makes it easier to work with and prevents the cake layers from getting soggy. 🥘
Assembly Timeline
Assemble the cake just before serving to maintain its perfect texture. If you must prep ahead, bake the layers, cool them, and store them separately. When ready to serve, add the filling and dust with powdered sugar right before slicing. This keeps the cake at its peak moisture and prevents the filling from leaking.
Freezing Fully Assembled
For maximum convenience, assemble the cake completely (including filling) and wrap it tightly in plastic wrap followed by aluminum foil. Freeze for up to 2 months. Thaw overnight in the fridge before serving. The texture remains rich and moist, though the filling may soften slightly—just a little extra powdered sugar on top fixes that!
Make-Ahead Serving
Plan for a crowd? Bake and store the layers separately, then assemble the cake just before your guests arrive. This way, you can focus on plating and presentation rather than last-minute baking. I like to dust with powdered sugar and add fresh berries right before serving—it makes the cake look (and taste) even more impressive. ✨

Frequently asked questions
Why does this recipe use 12 egg yolks instead of whole eggs?
The extra yolks create that signature velvety, moist texture that regular cake recipes can’t match. Each yolk adds natural fat and emulsifiers that keep the crumb tender and rich. Using just yolks also prevents the cake from becoming too dense—whole eggs would add too much structure and dryness.
Can I substitute cornstarch with something else? Yes! Use 2 tablespoons arrowroot powder or 2 tablespoons potato starch as a 1:1 replacement. These starches work similarly to create that signature tender crumb. Just
What’s the best way to tell when the cake is fully baked?
Insert a toothpick into the center—it should come out clean with just a few moist crumbs. The edges should pull away slightly from the pan, and the top should spring back when gently pressed. Opening the oven early causes sinking, so resist the urge to check before the 25-minute mark.
Can I make this cake in a different pan size?
For an 8-inch round pan, this recipe works perfectly. For a 9-inch pan, reduce baking time by 2-3 minutes (22-25 minutes total). For a 6-inch pan, increase time by 3-5 minutes (28-33 minutes). Always check with a toothpick—smaller pans bake faster due to less surface area.
Why did my cake crack on top?
Cracking usually happens from sudden temperature changes or overbaking. Let the cake cool in the pan for 10 full minutes before removing, and avoid opening the oven door early. If cracks appear, dust with extra powdered sugar—they’ll be less noticeable, and the cake will still taste delicious!
