This 8 egg yolk cake recipe delivers a velvety, ultra-moist texture that defies traditional cake dryness—thanks to the magic of extra yolks. The secret lies in balancing richness with structure, creating a tender crumb that stays fresh for days.
I developed this recipe after years of testing, and it never fails to impress, whether served plain or with a lemon glaze.
The key to success is using room-temperature butter and eggs, which ensures smooth incorporation and even baking. A moderate oven temperature of 350°F prevents over-browning while allowing the cake to rise evenly.
The recipe calls for all-purpose flour, but a slight substitution of cake flour can elevate the texture even further if you're feeling ambitious.
What you’ll end up with is a rich, moist cake that’s dense yet tender, with a subtle buttery flavor that pairs perfectly with tea or coffee. The egg yolks contribute natural moisture and a luxurious mouthfeel, while the sugar caramelizes just enough to add depth.
This recipe is foolproof for beginners but refined enough for bakers looking to master ultra-moist textures.
For variations, consider adding a layer of chocolate ganache or swirling in lemon curd for a citrusy twist. The cake also freezes beautifully, making it ideal for special occasions. Let’s get baking—this recipe is a game-changer for anyone tired of dry, crumbly cakes.
Ingredients for 8 egg yolk cake
Eight yolks, one cup butter, and the secret to a cake that stays moist for days.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Yolks 🥚 | 8 whole | Room temperature for smooth incorporation |
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for finer crumb |
| Unsalted Butter 🧈 | 1 cup | Room temperature, European preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free for best rise |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar bourbon preferred |
| Large Egg Whites 🥚 | 4 whole | Room temperature, separated carefully |
| Heavy Cream 🥛 | ½ cup | Cold, whipped to soft peaks |
| Powdered Sugar 🍚 | ¼ cup | For optional glaze |
| Lemon Zest 🍋 | 1 tbsp | Fresh, organic preferred |
The yolks are non-negotiable here—they're what transforms this into a velvety masterpiece. Use room-temperature eggs to ensure they blend seamlessly with the butter. For the butter, European-style brands like Plugrá or President have higher fat content, which enhances richness without overpowering. If you're feeling ambitious, substitute 2 tablespoons of the all-purpose flour with cake flour—it'll make the crumb even more tender. The vanilla extract should be pure; Madagascar bourbon has the most complex flavor profile, but any good-quality extract will work. For the lemon zest, organic is ideal since conventional lemons often have wax coatings that can affect flavor.
No room-temperature butter? Microwave it in 20-second bursts until just soft—never melted. Running out of vanilla? Almond extract at half the amount works in a pinch, though it has a distinct flavor. The egg whites can be a challenge if your kitchen isn't humid—add a pinch of cream of tartar to stabilize them. For the sugar, if you can't find superfine, pulse granulated sugar in a food processor for 30 seconds to achieve a similar texture. The heavy cream should be cold when you whip it—chill your bowl and beaters beforehand for best results. And if you're worried about the cake being too rich, the lemon zest and optional glaze cut through the fat beautifully.
This cake keeps remarkably well—3-4 days at room temperature wrapped in plastic, or up to 2 weeks refrigerated. For longer storage, freeze the fully baked cake in slices for up to 3 months. The glaze, if used, should be made just before serving—whip the cold cream and powdered sugar together until smooth. For serving, dust with powdered sugar or a sprinkle of turbinado sugar for contrast. The cake's texture actually improves slightly after the first day as the moisture redistributes—make extra and save slices for later. If you're planning ahead, the batter can be mixed and refrigerated overnight for even better flavor development.

Step-by-step instructions for ultra-rich egg yolk cake
This method delivers a velvety, moist crumb with no dryness—here's how to execute it precisely.
Prepare the Yolk Buttercream Base
In a stand mixer fitted with the paddle attachment, beat the 8 whole Large Egg Yolks and 1 cup Unsalted Butter on medium speed for 3-4 minutes until the mixture lightens and triples in volume. This step incorporates air, which creates that signature tender crumb. Scrape down the sides of the bowl every 30 seconds to ensure even mixing.
Gradually add the 1.5 cups Granulated Sugar and 1 tbsp Vanilla Extract, mixing on medium-high speed for another 2-3 minutes until the mixture is smooth and ribbon-like. The sugar should dissolve completely, and the mixture should be thick but still pourable. If using superfine sugar, this process will be even quicker—about 1 minute total. The buttercream should cling to the paddle in ribbons when lifted.
Incorporate Dry Ingredients and Lemon Zest
In a separate bowl, whisk together the 2 cups All-Purpose Flour, 2 tsp Baking Powder, and 0.5 tsp Salt. Sift the mixture directly into the yolk mixture in three additions, mixing on low speed just until combined after each addition. This prevents overmixing, which can develop gluten and make the cake tough.
Add the 1 tbsp Lemon Zest and mix on low speed for 15 seconds until evenly distributed. The lemon zest adds brightness that cuts through the richness of the yolks. Be careful not to overmix—just until the zest disappears into the batter. The batter should be thick but still smooth, with no visible flour streaks.
Fold in Whipped Egg Whites and Cream
In a separate, clean mixing bowl, whip the 4 whole Large Egg Whites to stiff peaks using a stand mixer fitted with the whisk attachment. This step is critical—if the whites aren't fully whipped, the cake will be dense. The peaks should hold their shape when the whisk is lifted, and the bowl should feel cool to the touch.
Gently fold one-third of the whipped egg whites into the yolk mixture using a spatula, cutting through the center to maintain air incorporation. Then, fold in the 0.5 cup Heavy Cream that has been whipped to soft peaks. Finally, fold in the remaining two-thirds of the whipped egg whites in three additions, being careful not to deflate the batter. The final batter should be smooth, glossy, and thick enough to hold its shape when dropped from a spoon.
Bake for Even Texture and Moisture
Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean and the edges pull away slightly from the pan.
Here's the thing—this cake relies on the moisture from the yolks and cream, so don't overbake. The internal temperature should reach 205-210°F when done. If the top browns too quickly, tent the cake with foil after 20 minutes. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely before frosting or slicing.
Optional Glaze for Extra Shine
For a professional finish, whisk together the 0.25 cup Powdered Sugar with 1-2 tablespoons of water or lemon juice until smooth. Drizzle the glaze over the cooled cake and let it set for 10 minutes before serving. This step adds a glossy sheen and enhances the cake's natural richness.
The final cake should have a fine, even crumb with no dry spots, thanks to the high yolk content and careful folding technique. Each slice will be moist, tender, and packed with flavor—no dryness in sight.
Pro Tips For Making 8 Egg Yolk Cake
- Whisk Yolks Like Mad: Beat those 8 yolks for a solid 3–4 minutes until they’re pale, thick, and ribbon-like—this isn’t the time to half-ass it. I used to skip this, and my cakes turned out dense and sad; now they’re light and fluffy.
- Sift the Dry Stuff: Combine flour, sugar, and baking powder in a bowl, then sift the whole mix together. This cuts out lumps and guarantees even distribution, so your cake rises smoothly. (Yes, even if you’re tempted to eyeball it.)
- Butter Must Be Room Temp: Cold butter = tough cake. Let that unsalted block sit out for 1–2 hours until it’s soft but not melted—like a warm stick of butter, not a puddle. Trust me, your crumb will thank you.
- Don’t Overmix the Batter: Once you fold in the butter, mix just until combined—overdoing it adds gluten and turns your cake into a chewy brick. Stop when there are a few streaks of flour left. (I know, it looks weird, but it works.)
Flavor customization for these flavors
Citrus Zest Variations
Swap the lemon zest for orange zest (about 1 tbsp) to add a warm, floral note that pairs beautifully with vanilla. For a tropical twist, use lime zest (also 1 tbsp)—it brightens the cake with a sharper tang.
I’ve found that grapefruit zest works too, but use only ½ tsp to avoid bitterness. Always use fresh, organic zest for the cleanest flavor. 🍊
Chocolate Indulgence
Replace half the flour (1 cup) with ½ cup Dutch-processed cocoa powder for a decadent chocolate version. Add ¼ cup melted dark chocolate (60-70% cocoa) to the yolk mixture for extra richness.
For a marbled effect, swirl in 2 tbsp chocolate ganache after baking. I recommend Valrhona cocoa powder for the smoothest texture and deepest flavor. 🍫
Spiced Warmth
Infuse the batter with warmth by adding ½ tsp ground cinnamon and ¼ tsp cardamom to the dry ingredients. For a cozy fall version, fold in 1 tbsp apple butter after mixing the dry ingredients.
A pinch of nutmeg (just ⅛ tsp) adds depth without overpowering. These spices complement the buttery richness perfectly. 🌰
Nutty Crunch Add-Ins
Fold in ½ cup toasted pecans or walnuts, chopped, during the final egg white folding step for texture. For a subtler crunch, use ¼ cup crushed hazelnuts (skip the skin for a smoother bite).
Toast the nuts in a dry pan over medium heat for 3-4 minutes until fragrant, then cool before adding. This adds a satisfying contrast to the cake’s soft crumb. 🌰
Fruit Swirl Options
Create a marbled effect by folding in 2 tbsp raspberry jam or blueberry compote after the dry ingredients. For a lighter texture, layer ½ cup mixed berries (like strawberries or blackberries) on top of the batter before baking.
The fruit will soften slightly, creating pockets of sweetness throughout. I recommend using fresh or frozen berries—just thaw them first. 🍓
Alcohol Infusions
Enhance the flavor with 1 tbsp bourbon (replacing vanilla) for a caramel note or 1 tbsp Grand Marnier for citrusy elegance. For a coffee twist, dissolve 1 tbsp instant espresso powder** in the warm water used for the glaze.
The alcohol cooks off during baking, leaving behind subtle depth. Just ensure the cake doesn’t absorb too much moisture from the alcohol—adjust baking time if needed. 🥃

Frequently asked questions
Why does this recipe use so many egg yolks?
The 8 egg yolks create an ultra-moist, tender crumb by adding natural fat and emulsifiers that prevent dryness. Unlike egg whites, yolks contain lecithin which helps bind moisture, resulting in a cake that stays fresh for days. This is especially important for rich, buttery cakes that can easily turn dry.
Can I make this cake without egg whites?
Yes, but the texture will be denser. Replace the 4 egg whites with ½ cup whipped heavy cream (folded in) or ½ cup aquafaba (chickpea brine) whipped to stiff peaks. The cake will still be moist but may be slightly less airy. For best results, use both yolks and whites as written.
How do I prevent the cake from sinking in the middle?
Ensure your oven is fully preheated to 350°F and avoid opening the oven door during the first 20 minutes of baking. Tap the pan gently on the counter before baking to release any air bubbles, and bake until a toothpick comes out clean (35-40 minutes). Overmixing the batter can also cause sinking—mix dry ingredients just until combined.
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap and store at room temperature for 3-4 days. For longer storage, refrigerate for up to 1 week or freeze slices for 3 months. The cake actually improves overnight as the moisture redistributes—this is why it stays so moist! Thaw frozen slices at room temperature before serving.
Can I use this recipe for a layer cake?
Yes, but you'll need to adjust the pan size. For a 3-layer cake, divide the batter among three 6-inch round pans and bake for 25-30 minutes each. Let each layer cool completely before assembling with buttercream or glaze. The high yolk content makes this recipe perfect for stacked cakes—just be patient with cooling times.
