Ingredients for amaury guichon cake
Elegance in every layer—these premium ingredients bring Amaury Guichon's Swiss bakery magic to your kitchen
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 ½ cups | Sifted for lightness, room temperature |
| Unsalted Butter 🧈 | 1 ½ cups | European-style, 82% fat, softened |
| Granulated Sugar 🍚 | 2 ½ cups | Superfine preferred for smooth texture |
| Large Eggs 🥚 | 8 whole | Room temperature, separated |
| Vanilla Extract 🌿 | 2 tbsp | Pure Madagascar bourbon preferred |
| Baking Powder 🧂 | 1 tbsp | Diamond Crystal, not aluminum-free |
| Salt 🧂 | ½ tsp | Fine sea salt, kosher preferred |
| Dark Chocolate 🍫 | 12 oz | 70% cacao, Valrhona or Callebaut |
| Heavy Cream 🥛 | 1 ½ cups | 36% fat, chilled for ganache |
| Powdered Sugar 🍚 | 4 cups | Confectioners' sugar, sifted |
| Unflavored Gelatin 🍬 | 1 tbsp | Bloomed in 3 tbsp cold water |
| White Chocolate Chips 🍫 | 1 cup | High-quality, for decorative shards |
| Cocoa Powder 🍫 | ½ cup | Dutch-processed, for dusting |
The butter and chocolate are non-negotiable here—European-style butter with 82% fat creates that signature velvety texture, while Valrhona or Callebaut 70% cacao delivers deep chocolate flavor without bitterness. I always buy my butter from Whole Foods or Eataly for the best quality, and the chocolate? Worth the splurge. For the flour, King Arthur or Gold Medal brands work best when sifted—don't skip this step. The vanilla extract should be pure Madagascar bourbon, not imitation. If you can't find it, French vanilla is the next best thing, but bourbon gives that authentic Guichon touch. Eggs must be room temperature—cold eggs create dense layers. Pro tip: Separate them while still warm from the fridge for easier handling.
No European butter? Plugrá or Land O'Lakes cultured butter works in a pinch, though the texture won't be identical. Running short on vanilla? Seeds from 1 vanilla bean scraped and steeped in 2 tbsp warm water gives the same intensity. The gelatin might be tricky to find—Great Jones or Knox brands are reliable. For the chocolate shards, if you can't find white chocolate chips, chop a white chocolate bar into thin slices and freeze them for 20 minutes before using. The cocoa powder is crucial for that professional dusting—Dutch-processed gives the glossy finish Guichon loves. And if you're feeling ambitious, make your own powdered sugar by blending granulated sugar with 1 tbsp cornstarch in a food processor for 30 seconds.
The buttercream and ganache keep beautifully—3 days refrigerated if stored in airtight containers with parchment between layers. The cake itself stays fresh for 5 days if wrapped tightly in plastic. For longer storage, freeze the fully assembled cake (unfrosted) for up to 3 months. Thaw overnight in the fridge before serving. The chocolate shards can be made a week ahead and stored in an airtight container at room temperature. I always make extra ganache—it's perfect for filling cupcakes or topping other desserts. The key to presentation is dusting the cocoa powder through a fine-mesh sieve just before serving—Guichon's signature move for that bakery-fresh look.

Step-by-step instructions for Amaury Guichon cake
Unlock the secrets of Swiss bakery perfection with this meticulous layering technique.
Prepare the Sponge Cake Bases
Preheat your oven to 350°F and grease three 8-inch round cake pans with butter, then line the bottoms with parchment paper. In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2.5 cups granulated sugar on medium speed until light and fluffy—this should take about 5-7 minutes. The mixture should nearly triple in volume and turn pale.
Add the 8 whole large eggs, one at a time, beating well after each addition. Incorporate the 2 tbsp vanilla extract and mix for another 30 seconds. In a separate bowl, whisk together the 3.5 cups all-purpose flour, 1 tbsp baking powder, and 0.5 tsp salt. Sift this dry mixture over the butter-egg mixture in three additions, mixing on low speed just until combined—overmixing develops gluten and makes the cake dense.
Divide the batter evenly among the three prepared pans. Bake for 20-25 minutes or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This cooling step is critical—it prevents the layers from becoming soggy when assembling.
Create the Dark Chocolate Ganache
While the cakes cool, prepare the dark chocolate ganache by chopping the 12 oz dark chocolate into small pieces. In a heatproof bowl set over a saucepan of simmering water (double boiler), gently melt the chocolate, stirring occasionally until smooth. Remove from heat and let it cool slightly for 2 minutes.
Add the 1.5 cups heavy cream to the melted chocolate, whisking until the mixture is silky and glossy. Let the ganache cool to room temperature—it should thicken slightly but still be pourable. This ganache will serve as the luscious filling between each cake layer, adding richness and moisture.
Here's the thing—don't rush this step. The ganache needs to be at the perfect consistency to create clean, professional-looking layers. If it's too runny, chill it for 10 minutes before using. If it thickens too much, gently reheat it for 10-15 seconds in the microwave, stirring in between.
Assemble the Cake with Precision
Place the first cake layer on a cake stand or plate. Using a serrated knife, level the top if needed. Spread a thin, even layer of the dark chocolate ganache over the first cake layer—about ¼ cup—leaving a ½-inch border around the edges. This border prevents the ganache from oozing out during assembly.
Place the second cake layer on top, gently pressing down to create a clean, flat surface. Repeat the process, spreading another ¼ cup of ganache over the second layer and placing the third cake layer on top. Chill the assembled cake in the refrigerator for 30 minutes to allow the ganache to set slightly and hold the layers together.
Once chilled, use a long serrated knife to trim any uneven edges, creating a perfectly round cake. This step ensures a professional finish and makes slicing easier. Wrap the cake tightly in plastic wrap and refrigerate for at least 4 hours—preferably overnight—to allow the flavors to meld and the ganache to fully set.
Prepare the White Chocolate Ganache and Decorate
To create the white chocolate ganache, bloom the 1 tbsp unflavored gelatin in 3 tbsp cold water for 5 minutes until it becomes jelly-like. In a heatproof bowl, combine the 4 cups powdered sugar and 0.5 cup cocoa powder, then slowly whisk in 1 cup hot water until smooth. Stir in the bloomed gelatin until fully dissolved.
In a separate bowl, melt the 1 cup white chocolate chips with 1 cup heavy cream using a double boiler, stirring until smooth. Gradually pour the melted white chocolate mixture into the powdered sugar mixture, whisking constantly until fully combined and glossy. Let the ganache cool to room temperature—it should thicken to a spreadable consistency.
Once the cake has chilled overnight, remove it from the refrigerator and carefully level the top if needed. Spread the white chocolate ganache evenly over the top of the cake, creating a smooth, even layer. Use a spatula to create decorative swirls or patterns if desired. Finally, dust the sides of the cake with a fine mesh sieve filled with 0.5 cup cocoa powder for a striking contrast. Let the cake sit at room temperature for 1 hour before slicing to allow the ganache to set.
Serve with Confidence
Slice the cake into 8 even portions using a long serrated knife that has been dipped in hot water and wiped dry—this ensures clean cuts. Each slice should reveal the beautiful layers of sponge cake, dark chocolate ganache, and white chocolate ganache, creating a stunning visual and textural experience.
Serve the cake at room temperature for the best texture and flavor. The contrast between the light, airy sponge cake and the rich, velvety ganache layers is what makes this cake truly exceptional. Store any leftovers in the refrigerator for up to 5 days, bringing them to room temperature before serving again.
Pro Tips For Making Amaury Guichon Cake
- Whip Butter Until Pale: Amaury Guichon’s cake relies on properly emulsified butter—beat it with the sugar until it’s almost white (about 8-10 minutes). I used to stop at "light and fluffy," but that’s where the texture gets gummy. Push through the resistance; the payoff is a cake that’s tender, not dense. ---
- Room Eggs for 24 Hours: Cold eggs from the fridge won’t blend smoothly, and they can curdle the batter. Pull them out a day ahead and let them sit in the fridge (not on the counter)—this evens out the temperature and ensures a silky finish. Yes, it’s weird, but it works every time. ---
- Sift Flour Twice: Guichon’s recipe demands a light, airy crumb, and unsifted flour is its enemy. Sift it into the bowl first, then sift again before folding it in. I learned this after my first attempt looked like a brick—don’t skip it, even if you’re tempted to "save time." ---
- Bake at 325°F, Not Hotter: The oven must be preheated and set to 325°F—no exceptions. I once baked mine at 350°F for "faster results," and the outside burned before the center set. Slow and steady wins here; the cake’s structure depends on even heat.
Best sauces and condiments for this dish
Dark Chocolate Ganache
Amaury Guichon’s signature dark chocolate ganache is the heart of this cake—rich, velvety, and perfectly balanced. I use Valrhona or Callebaut 70% cacao chocolate for its deep flavor without bitterness. Melt 12 oz of chocolate in a double boiler, then whisk in 1.5 cups heavy cream until silky. Let it cool to 70°F before assembling—this ensures it sets beautifully between layers without melting. 🍫
White Chocolate Buttercream
The white chocolate buttercream topping adds a delicate contrast to the dark layers. Bloom 1 tbsp gelatin in 3 tbsp cold water, then whisk it into a smooth mixture of 4 cups powdered sugar, ½ cup cocoa powder, and 1 cup hot water. Melt 1 cup white chocolate chips with 1 cup heavy cream in a double boiler, then combine gently. This creates a light, airy frosting that stays glossy without being overly sweet. ✨
Chocolate Shard Crunch
For texture, Guichon’s recipe includes white chocolate shards—freeze 1 cup white chocolate chips for 20 minutes, then slice into thin strips. Place them between layers for a crisp contrast that cuts through the richness. I like to toast them briefly in the oven for 1-2 minutes at 350°F to enhance their flavor. 🔥
Cocoa Powder Dusting
The final touch is Dutch-processed cocoa powder dusted lightly over the sides for a bakery-fresh finish. Use a fine-mesh sieve and tap gently to create an even, elegant coating. This step isn’t just decorative—it adds a subtle chocolate aroma that elevates the whole presentation. 💫
Optional Berry Compote
For a seasonal twist, I sometimes add a raspberry or blackberry compote between layers. Simmer 1 cup berries with 2 tbsp sugar and 1 tsp lemon juice until thickened, then strain. Spread a thin layer between sponge cakes for a bright, tangy contrast to the chocolate. 🍓
Vanilla Bean Infusion
To deepen the flavor, infuse the buttercream with 1 vanilla bean (split and scraped) while melting the white chocolate. The natural oils from the bean add a luxurious depth that makes the cake taste even more professional. I always keep a few beans on hand for this exact purpose. 🌿

Frequently asked questions
Can I make this cake without a stand mixer?
For the sponge cake, use a hand mixer or even whisk by hand—just beat the butter and sugar vigorously for 8-10 minutes until pale and fluffy. The key is patience: work in short bursts to avoid overheating your arms. For the ganache, a double boiler is ideal, but you can melt the chocolate in 20-second intervals in the microwave, stirring between each interval to prevent scorching. The buttercream can also be made by hand using a whisk in a large bowl.
Why does the recipe call for European-style butter?
European-style butter has a higher fat content (82% vs. 80% in American butter) and less water, which creates a richer, more velvety texture in the sponge cake. The lower water content also prevents the cake from becoming dense. If you can't find it, Plugrá or Land O'Lakes cultured butter works best as a substitute, though the texture won't be identical. For the ganache, the higher fat content ensures a smoother, more stable consistency.
How do I fix a cake that's cracked or sunken?
Cracking or sinking usually happens from overmixing or opening the oven too soon. If your cake has minor cracks, simply level the top with a serrated knife before assembling. For sunken centers, the issue is often underbaking—always check with a toothpick (20-25 minutes at 350°F should be enough). If the cake is already assembled, you can "fix" it by adding a thin layer of ganache on top and refrigerating for 1 hour to firm it up. For next time, make sure your oven is properly calibrated and avoid opening the oven door during baking.
Can I substitute the white chocolate ganache with regular buttercream?
While you can use traditional buttercream, you'll lose the signature lightness and glossy finish. For a closer match, make an Italian meringue buttercream by whipping egg whites to stiff peaks, then gradually adding hot sugar syrup while whipping. Chill the meringue, then beat in softened butter and powdered sugar. This method creates a stable, light buttercream that holds its shape better than American buttercream. If you're short on time, a Swiss meringue buttercream (egg whites + sugar cooked to 160°F) works too.
How far ahead can I prepare the components?
You can make the sponge cakes 1 day ahead and store them in airtight containers at room temperature. The dark chocolate ganache keeps for 3 days refrigerated in an airtight container. The white chocolate buttercream can be made 2 days ahead and stored in the fridge—just rewhip it briefly before using. The chocolate shards can be prepared 1 week ahead and stored in an airtight container. Assemble the cake the day before serving for the best texture and flavor integration. The cake itself stays fresh for 5 days refrigerated if wrapped tightly in plastic.
