Ingredients for amaury guichon cake
Precision ingredients for Guichon's signature cake—where texture and flavor harmony matter most.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, European-style preferred |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smooth batter |
| Dark Chocolate 🍫 | 8 oz | 70% cacao, chopped fine |
| Large Eggs 🥚 | 4 whole | Room temperature, separated |
| Espresso Powder ☕ | 2 tbsp | High-quality, finely ground |
| Baking Powder 🍞 | 1 ½ tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar preferred |
| Heavy Cream 🥛 | 1 ½ cups | Cold, full-fat for ganache |
| Dark Chocolate 🍫 | 12 oz | 70% cacao, chopped for ganache |
| Butter 🧈 | ½ cup | Unsalted, room temperature |
The foundation starts with European-style butter—its higher fat content yields a richer crumb. For flour, King Arthur or Gold Medal brands work best due to their protein balance. Valrhona or Callebaut dark chocolate is ideal for the cake layers, but Ghirardelli is a reliable alternative. Espresso powder should be freshly ground—pre-ground loses potency quickly. Guichon's technique calls for room-temperature eggs, which incorporate more easily for that signature airy texture. The vanilla extract matters too—Madagascar bourbon adds depth without overpowering the chocolate-espresso base.
No European butter? Plugrá or Land O'Lakes work in a pinch, though texture may be slightly less tender. Substituting cocoa powder for dark chocolate? Use 2 tbsp unsweetened cocoa plus 2 oz melted butter per 8 oz chocolate called for. For the ganache, heavy cream must be cold—room temperature cream creates a grainy texture. Short on time? Double-strength espresso (1 tbsp per 1 oz water) can replace powder. The baking powder is non-negotiable—aluminum-free types like Diamond Crystal prevent metallic aftertaste. Pre-sifted flour? Sift again—Guichon's method relies on aeration for those tender layers.
Store cake layers at room temperature in airtight containers for up to 3 days, separated by parchment. Ganache components keep separately—chocolate chunks last 6 months in the freezer, cream 1 week. For assembly, let layers return to room temperature before adding ganache to prevent condensation. The finished cake stays impressive for 5 days at room temperature or 2 weeks refrigerated. Slice with a hot knife for that signature crack—Guichon's signature touch.

Step-by-step instructions for amaury Guichon's cake recipe
Master the technique behind Guichon's signature cake—moist, tender layers topped with a luxurious chocolate ganache crust.
Prepare the Cake Batter for Perfect Texture
In a stand mixer fitted with the paddle attachment, cream the 1.5 cups unsalted butter and 2 cups granulated sugar on medium speed for 5-7 minutes until light and fluffy. You're looking for a texture that nearly triples in volume and becomes pale in color—this incorporates air that will create that signature tender crumb. Scrape down the sides of the bowl with a spatula to ensure even mixing.
Add the 4 whole large eggs, one at a time, mixing well after each addition. Then incorporate the 1 tbsp vanilla extract and 2 tbsp espresso powder, mixing just until combined. In a separate bowl, whisk together the 2.5 cups all-purpose flour, 1.5 tsp baking powder, and 0.5 tsp salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until incorporated—overmixing develops gluten and creates a tough cake.
Incorporate Chopped Chocolate for Rich Depth
Fold in the 8 oz finely chopped 70% dark chocolate using a silicone spatula, ensuring even distribution throughout the batter. The chocolate should be melted just enough to soften but not completely liquefy—this creates pockets of molten chocolate in each bite. Divide the batter evenly among three 8-inch round cake pans lined with parchment paper and greased with butter.
Bake in a preheated 350°F oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should be golden on top but still slightly springy to the touch—this ensures maximum moisture. Allow them to cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Create the Signature Chocolate Ganache Topping
In a heatproof bowl, combine the 12 oz chopped 70% dark chocolate and 1.5 cups cold heavy cream. Let the mixture sit for 2 minutes to allow the cream to slightly soften the chocolate. Place the bowl over a saucepan of simmering water, ensuring the bottom of the bowl doesn't touch the water, and stir gently until the chocolate is completely melted and the ganache reaches 110°F. Remove from heat and let it cool slightly to 95°F—this temperature ensures a glossy, crackly finish.
While the ganache cools, level the tops of the cake layers if needed. Once the ganache reaches the ideal temperature, spread it evenly over the top and sides of one cake layer, creating a smooth base. Assemble the remaining layers, pressing gently to adhere.
Achieve the Crispy Chocolate Crown
Place the assembled cake on a wire rack set over a baking sheet. Chill in the refrigerator for 2 hours to set the ganache. Once firm, use the 0.5 cup unsalted butter to create a thin, even layer over the entire cake surface. This butter layer creates a barrier that prevents the ganache from absorbing too much moisture from the cake, ensuring that crispy texture Guichon is known for.
Return the cake to the refrigerator for an additional 1 hour to fully set. Before serving, use a sharp knife to create clean edges on the ganache layer. The final result should be a cake with moist, tender layers and a luxurious, crackly chocolate exterior that snaps perfectly with each bite.
Pro Tips For Making Amaury Guichon Cake
- Temper the Chocolate: DESCRIPTION: Melt the dark chocolate slowly over a double boiler—never microwave it. I learned this the hard way when my first batch turned grainy and clumpy. If you’re in a rush, chop it finely first, but don’t skip the low-and-slow method. The texture of this cake depends on it.
- Cream Butter Cold: DESCRIPTION: Take the unsalted butter straight from the fridge and beat it with the sugar until it’s pale and fluffy—about 3-4 minutes. Warm butter makes for a dense cake, and this step is non-negotiable. Skip the shortcut, or you’ll regret it later.
- Don’t Overmix the Batter: DESCRIPTION: Once the flour is incorporated, stop mixing as soon as it’s just combined. Overworking the batter introduces gluten, and this cake should be tender, not chewy. Fold it gently with a spatula—like you’re tucking in a baby, not punching it.
- Rotate the Pan Mid-Bake: DESCRIPTION: Swap the cake pans from front to back in the oven halfway through baking. This ensures even browning, especially if your oven runs hot on one side. I used to ignore this, and my edges would burn while the centers stayed raw—annoying, but easy to fix.
Troubleshooting your amaury guichon cake
Crackly Ganache Fail
If your ganache turns out grainy or dull instead of glossy and crackly, it's likely due to temperature control. Guichon's method requires precise heating—never exceed 110°F when melting the chocolate. Use a candy thermometer for accuracy.
Also, ensure your heavy cream is ice-cold—room temperature cream creates a grainy texture. If it happens, reheat gently with 1 tbsp extra cream per cup of ganache until smooth again. 🌡️
Dense Cake Layers
Overmixing the batter is the #1 cause of dense layers. Mix dry ingredients just until combined—no more than 10 strokes with a spatula. If your cake turns out too heavy, try folding in an extra ¼ cup whipped egg whites before baking next time.
Also, check your baking powder—expired leavening agent can make cakes dense. For a quick fix, brush warm layers with simple syrup before assembling to add moisture. 🍞
Ganache Too Soft
If your ganache stays too soft even after chilling, it's likely too warm when poured. Guichon's method requires cooling to 95°F before assembly. For a firmer finish, add 1 tsp cornstarch to the ganache mixture before melting.
Another trick: spread a thin layer of butter over the ganache after it sets—this creates that signature crispy barrier. If it's still too soft, return to the fridge for 30 more minutes. ❄️
Uneven Layers
Uneven cake layers often happen from improper cooling or leveling. Let cakes cool completely before removing from pans—at least 1 hour. Use a serrated knife or cake leveler to trim domed tops.
For assembly, place layers on a cooling rack to prevent sogginess. If layers shift during assembly, chill the cake 10 minutes between each layer to help it hold shape. 🔨
Chocolate Sinking
Chopped chocolate sinking in the batter? It's likely not melted enough. Guichon's technique calls for softened but not liquid chocolate. For next time, melt the chocolate just until smooth, then cool to 90°F before folding into batter.
If it's already baked, try reheating the cake layers (wrapped in foil) at 300°F for 10 minutes—this helps redistribute moisture and prevents sinking in future attempts. 🍫
Cake Too Dry
Dry cake usually means overbaking or insufficient moisture. Check your oven temperature—a 350°F thermometer reading is critical. For extra moisture, brush warm layers with 2 tbsp apricot jam before assembling.
If already baked, try soaking layers with 2 tbsp coffee or espresso between ganache applications. Store leftovers with parchment between layers to maintain freshness. 💧

Frequently asked questions
Why does Amaury Guichon use espresso powder in his cake?
Espresso powder enhances the chocolate flavor without adding moisture that could make the cake dense. The subtle coffee notes create a sophisticated depth that pairs beautifully with the dark chocolate, while the powder form ensures even distribution throughout the batter. Guichon's technique balances these flavors to create a dessert that's both rich and refined.
Can I substitute regular chocolate for the 70% cacao dark chocolate?
Not ideal, but you can use 60% cacao dark chocolate if that's all you have. The lower cacao percentage will make the cake slightly sweeter and less intense. For best results, stick with 70% cacao—it provides that perfect balance of bitterness and sweetness that defines Guichon's signature style.
How do I achieve that signature crackly chocolate top?
The key is tempering the ganache to 95°F before spreading and using a thin butter layer afterward. This creates a moisture barrier that keeps the ganache crispy. Chill the cake for 3 hours total—2 hours after assembly, then 1 hour after adding butter. Patience is crucial for that perfect snap when sliced.
What's the best way to store leftovers?
Wrap individual layers in plastic wrap and store at room temperature for up to 3 days. For longer storage, refrigerate the whole cake (covered) for 7 days. Never freeze the assembled cake—it can make the ganache soggy. For single layers, freeze for up to 1 month, thawing at room temperature before reassembling.
Can I make this cake without a stand mixer?
Yes! Use a hand mixer or even a whisk with strong arm muscles. Cream the butter and sugar for 8-10 minutes by hand until light and fluffy. For the ganache, a double boiler works perfectly—just use a candy thermometer to monitor the temperature precisely. The key is patience and attention to detail, just like Guichon's professional techniques.
