Ingredients for amaury guichon cake
Twelve ingredients, Swiss bakery magic, and nutty swirls that steal every show.
| Ingredient | Amount | Notes |
|---|---|---|
| Dark Chocolate (70% Cocoa) 🍫 | 12 oz | High-quality, European-style preferred |
| European-Style Unsalted Butter 🧈 | 2 cups | 80% fat content, softened at room temp |
| Granulated White Sugar 🍚 | 2 ½ cups | Superfine sugar for smoother texture |
| Large Eggs 🥚 | 6 whole | Room temperature for even mixing |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted before measuring for lightness |
| Hazelnuts (Whole) 🌰 | 1 ½ cups | Toasted until golden, skinned |
| Almonds (Whole) 🌰 | 1 cup | Toasted and finely chopped |
| Unsweetened Cocoa Powder 🍫 | ½ cup | Natural or Dutch-processed |
| Vanilla Extract 🌿 | 2 tbsp | Pure Madagascar bourbon preferred |
| Salt 🧂 | ½ tsp | Fine sea salt for delicate flavor |
| Heavy Cream 🥛 | 2 cups | 36% fat content for rich ganache |
| Powdered Sugar 🍚 | 1 cup | For dusting layers between assembly |
| Rum Extract (Optional) 🍹 | 1 tsp | For depth of flavor in sponge |
The chocolate and butter are non-negotiable here. Valrhona or Callebaut chocolate delivers that signature Swiss richness, but Ghirardelli or Lindt work in a pinch. For the butter, Plugrá or President (European-style) give that velvety texture—don’t compromise with regular American butter. Toast your nuts in a dry pan until they’re fragrant and golden, then rub them between towels to remove skins. Whole Foods or specialty grocers carry pre-toasted nuts if you’re short on time, but fresh-toasted always wins. The cocoa powder? Valrhona or Dutch-processed for smoother ganache.
No European chocolate? High-quality 70% dark chocolate from a reputable brand will do, but you’ll lose some depth. Running out of hazelnuts? Pecans or macadamias work in a pinch, though texture changes slightly. The vanilla extract can be swapped for vanilla bean paste if you’re feeling fancy. For the rum extract, Kahlúa or coffee liqueur adds complexity without overpowering. Prefer not to use alcohol? Extra vanilla bean seeds (scraped from a pod) or a splash of orange liqueur works too. And if your heavy cream is light (30% fat), add 2 tbsp powdered milk to compensate—ganache needs fat to shine.
Store your nuts in the freezer to preserve freshness, but bring them to room temp before toasting. The chocolate and butter should stay in a cool, dark place—not the fridge—to prevent condensation. Once assembled, this cake keeps beautifully for 5 days at room temperature, wrapped tightly in parchment. For longer storage, slice and freeze portions between parchment—up to 3 months. The ganache might firm up slightly when chilled, but brings back to perfection with 10 seconds in the microwave. Serve at room temperature for that signature Swiss patisserie experience.

Step-by-step instructions for Amaury Guichon cake
Let's bring Swiss bakery elegance to your kitchen with this decadent nutty swirl masterpiece.
Prepare the Nut Paste and Chocolate Ganache
Toast the 1.5 cups hazelnuts and 1 cup almonds separately in a dry skillet over medium heat for 8-10 minutes, stirring constantly, until they're golden brown and fragrant. Immediately transfer to a clean kitchen towel and rub vigorously to remove skins—this step creates that signature Swiss nutty texture. Let cool completely before processing.
Once cool, pulse the toasted nuts in a food processor until you achieve a fine, paste-like consistency (about 2-3 minutes). Set aside. In a heatproof bowl, combine the 12 oz dark chocolate (70% cocoa) and 2 cups heavy cream over a saucepan of simmering water, stirring gently until the chocolate melts completely and the ganache reaches 110°F. Let cool to 90°F before using—this precise temperature ensures a silky ganache that won't seize when incorporated.
Create the Nutty Swirl Dough
In a stand mixer fitted with the paddle attachment, beat the 2 cups European-style unsalted butter and 2.5 cups granulated white sugar on medium speed for 4-5 minutes until light and fluffy, scraping down the bowl as needed. Add the 6 whole large eggs one at a time, mixing well after each addition, then incorporate the 2 tbsp vanilla extract and 1 tsp rum extract (if using). The mixture should be pale, thick, and ribbon-like when you lift the paddle.
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 0.5 cup unsweetened cocoa powder, and 0.5 tsp salt. Gradually add to the butter mixture on low speed, mixing just until combined—overmixing develops gluten and makes the cake dense. Fold in the nut paste using a spatula until evenly distributed. Divide the dough evenly between two 9-inch round cake pans lined with parchment paper.
Bake and Assemble the Layers
Preheat your oven to 350°F. Bake the cake layers for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. While the cakes cool, prepare the ganache by gently folding the nut paste into the cooled chocolate mixture until fully incorporated.
Once completely cool, level the cake layers if needed. Place one layer on a cake stand and spread a thin layer of ganache over the top. Dust with 1 cup powdered sugar for that signature Swiss finish. Repeat with the second layer, then cover the entire cake with remaining ganache. Chill in the refrigerator for at least 4 hours (or overnight) to set properly. The cake will keep in the fridge for up to 5 days, though I promise it won't last that long!
Pro Tips For Making Amaury Guichon Cake
- Temper the Chocolate: Chop the 70% dark chocolate into small, even pieces—no bigger than 1-inch chunks—and melt it with the butter over a double boiler, stirring every 30 seconds. I learned this the hard way: skipping the tempering step means your cake might seize or develop streaks later, and no one wants a grainy texture in a Guichon cake. ---
- Whisk Eggs Separately: Beat the egg yolks and whites separately until the yolks are pale and ribbon-like, then fold the whites into the batter last. After burning through three batches where the cake collapsed, I realized the whites need to stay fluffy—folding them in gently at the end keeps that airy structure intact. ---
- Avoid Overmixing the Batter: Mix the flour, sugar, and melted chocolate-butter combo just until combined—no more than 20 strokes with a spatula. Overmixing develops gluten, and this cake is all about that tender, melt-in-your-mouth crumb. Trust me, it’s easier than you think. ---
- Bake in Two Stages: Start the cake at 350°F (175°C) for 10 minutes, then drop the heat to 325°F (160°C) for the remaining 30-35 minutes. The initial high heat sets the edges, while the lower temp ensures even baking without a dry top. I was skeptical until I tried it—now it’s non-negotiable.
Dietary considerations for this amaury guichon cake
Gluten-Free Adaptation
Replace the 2.5 cups all-purpose flour with a 2:1 gluten-free flour blend like Bob’s Red Mill or King Arthur. For best results, use 2 cups blend + ½ cup cornstarch to mimic the structure. Sift the blend thoroughly to prevent clumping, and increase the eggs to 7 large for moisture balance. The nut paste will still add richness, but the texture will be slightly denser—expect a 10-15 minute longer bake time at 325°F to ensure even cooking. 🌾
Vegan Version
Swap the European-style butter for 2 cups refined coconut oil (solid at room temp) and use 6 flax eggs (6 tbsp ground flaxseed + 18 tbsp water, rested 5 minutes). For the ganache, melt 12 oz vegan dark chocolate with 2 cups full-fat coconut cream (chilled overnight). The nut paste remains the same, but dust layers with powdered coconut sugar instead of powdered sugar. Chill for 6+ hours to set properly—vegan ganache sets slower. 🌱
Nut-Free Option
Omit the hazelnuts and almonds entirely and replace with 1.5 cups finely chopped dried apricots (soaked in warm water for 10 minutes, drained) or 1 cup sunflower seeds (toasted until golden). For extra moisture, add 2 tbsp apricot jam to the nut paste substitute. The flavor profile shifts to dried fruit or seed-forward, but maintains the cake’s signature texture. Store-bought nut-free chocolate spreads can also add depth without nuts. 🌰
Lower Sugar
Reduce the 2.5 cups granulated sugar to 1.5 cups and replace the remaining 1 cup with 1 cup monk fruit sweetener (like Lakanto). Use 1 extra egg white for structure and fold in ½ cup Greek yogurt to the batter for moisture. The ganache will still need 1 cup powdered sugar for stability, but the overall sweetness drops significantly. Taste the batter before baking—adjust with 1-2 tbsp extra sweetener if needed. 🍚
Allergen-Friendly Tips
For egg allergies, use 6 flax eggs (as in the vegan version) and ensure all cross-contamination is avoided—clean all equipment thoroughly. For dairy-free, confirm your chocolate is certified dairy-free (like Enjoy Life brand) and use dairy-free heavy cream (like Califa Farms). Always check labels on extracts (vanilla/rum) for hidden allergens. Store all modified versions in airtight containers with clear labels. ✨

Frequently asked questions
Why does Amaury Guichon's cake need toasted nuts?
Toasting the nuts enhances their natural flavors and removes skins for a smoother texture. The nut paste creates those signature swirls that give the cake its signature Swiss bakery character. Skipping this step means losing both the visual appeal and rich, toasty flavor that makes this cake special.
Can I make this cake without a stand mixer?
Yes, but you'll need to be extra careful with mixing. Use a hand mixer or whisk to combine the butter and sugar until light and fluffy, then add eggs one at a time. For the nut paste, a food processor is ideal, but you can grind the nuts in a spice grinder or even pulse them in a blender. Just be patient—hand mixing takes more elbow grease!
How do I know when the ganache is ready to use?
The ganache should reach 110°F when melted, then cool to 90°F before incorporating the nut paste. This temperature range ensures it's silky smooth and won't seize when folded. Use a candy thermometer for precision—if it's too hot, it'll melt the chocolate unevenly; too cool, and it won't blend properly.
Why does the cake need to chill for so long?
Chilling for 4+ hours (or overnight) is crucial for setting the ganache properly and preventing the layers from sliding. The cold temperature helps the chocolate firm up, creating that signature Swiss patisserie texture. Patience here makes all the difference—rushing leads to a messy, runny cake.
What's the best way to store leftovers?
Wrap individual slices tightly in plastic wrap, then place in an airtight container with parchment between layers. This keeps the cake fresh for 5 days at room temperature. For longer storage, freeze portions for up to 3 months. When reheating, microwave for 10-15 seconds to restore that perfect melt-in-your-mouth ganache.
