Ingredients for america's test kitchen flourless chocolate cake
Eight ingredients. One legendary texture. No eggs, no flour—just pure chocolate bliss.
| Ingredient | Amount | Notes |
|---|---|---|
| High-Quality Dark Chocolate (70% Cocoa) 🍫 | 8 oz | Valrhona or Ghirardelli preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for tempering |
| Granulated Sugar 🍚 | 1 cup | Superfine preferred for smoothness |
| Large Egg Whites 🥚 | 4 whole | Room temperature, separated |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar preferred |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| All-Purpose Flour 🌾 | ¼ cup | For dusting pan only |
| Flaky Sea Salt 🧂 | 1 tsp | For garnish, optional |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for best texture |
| Raspberry Coulis 🍓 | ½ cup | For serving, optional |
The chocolate is non-negotiable here. Valrhona or Ghirardelli at 70% cocoa delivers that signature depth—anything lower and you lose that fudgy density. Grab the bars, not chips, and chop them yourself for even melting. Butter? Cold and cubed is key—don't let it soften before mixing. The egg whites need to be room temp, so take them out 20 minutes before baking. Superfine sugar dissolves better, but if you've got regular, pulse it in a food processor for a few seconds. Whole Foods or Trader Joe's stock great quality chocolate and baking staples.
No vanilla extract? Vanilla bean paste works too, but pure Madagascar has that extra je ne sais quoi. Running short on egg whites? Aquafaba (chickpea brine) at 1:1 ratio gives similar structure, though texture might be slightly lighter. The flour is just for dusting the pan—skip it if you're using parchment paper. For the garnish, Maldon sea salt is the gold standard, but any flaky salt works. The raspberry coulis can be store-bought (like Bon Appétit's jarred version) or homemade—simmer frozen raspberries with a touch of sugar until thickened. No coulis? Whipped cream is always a winner.
Chocolate stays fresh in an airtight container for 5 days at room temp, or 2 weeks refrigerated. Slice before storing to prevent drying. For longer storage, wrap tightly in plastic and freeze for up to 3 months. The cake reheats beautifully—microwave a slice for 10 seconds to restore that melt-in-your-mouth texture. Portion the whipped cream or coulis separately so they stay fresh longer. Leftovers? They're rare, but if they happen, store the toppings in the fridge and assemble just before serving.

Step-by-step instructions for america's test kitchen flourless chocolate cake
Here's the method for a rich, fudgy chocolate cake with perfect layers—no eggs required.
Temper the Dark Chocolate for Maximum Smoothness
Start by chopping the 8 oz high-quality dark chocolate (70% cocoa) into small, even pieces. Place 0.75 cup unsalted butter in a heatproof bowl set over a pot of barely simmering water, ensuring the bottom doesn't touch. Once the butter melts completely, remove it from heat and whisk in the chopped chocolate until fully melted and smooth. This tempering process creates a glossy, velvety texture that's the secret to a professional finish.
Stir in 1 cup granulated sugar and 0.5 tsp kosher salt until fully dissolved. Let the mixture cool to 100°F—this ensures the cake rises properly without spreading too much. I use a candy thermometer for precision, but you can also test by dipping a spoon in the mixture; it should coat the back smoothly without being runny. This step is non-negotiable for the right texture.
Whip the Egg Whites to Stiff Peaks
While the chocolate mixture cools, separate the 4 whole large egg whites from their yolks (save the yolks for another use if desired). Using a stand mixer fitted with the whisk attachment, beat the egg whites on medium speed until soft peaks form. Gradually increase the speed to high and continue whipping until the egg whites form stiff, glossy peaks that hold their shape when the whisk is lifted. This typically takes 3-5 minutes—don't rush it, or the cake won't rise properly.
Gently fold 1 tbsp vanilla extract into the egg whites using a spatula, being careful not to deflate them. The mixture should remain light and airy. Here's the thing—if you see any deflation, don't panic. Just gently fold again until the volume returns. The goal is to incorporate the vanilla without losing the structure you've built.
Combine Wet and Dry Ingredients for a Fudgy Texture
Once the chocolate mixture has cooled to 100°F, gradually fold in the egg whites using a spatula, working in three additions. After each addition, fold until just combined—this ensures the egg whites stay incorporated without overmixing. The batter should be thick, glossy, and fudgy, with no visible streaks of egg white. If it looks too thin, let it rest for 5 minutes to thicken slightly before proceeding.
In a separate bowl, whisk together 0.25 cup all-purpose flour and 1 tsp flaky sea salt. Sift this mixture over the chocolate batter and fold gently until just combined. This step is critical—overmixing will develop gluten and make the cake dense. The batter should be thick enough to hold its shape when dropped from a spoon, but still smooth and velvety.
Bake in a Preheated Oven for Perfect Layers
Preheat your oven to 350°F. Lightly dust an 8-inch round cake pan with 0.25 cup all-purpose flour, tapping out any excess. Pour the batter into the pan and smooth the top with a spatula. Bake for 35-40 minutes, or until the top is set and a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). The cake should spring back slightly when pressed gently in the center.
Real talk: The cake will look underdone when you take it out, but it continues cooking as it cools. Let it rest in the pan for 10 minutes, then run a knife around the edges to loosen it. Invert onto a wire rack to cool completely before slicing. This resting period ensures the layers stay intact and the texture remains fudgy throughout.
Serve with Whipped Cream and Raspberry Coulis
While the cake cools, whip the 1 cup heavy whipping cream to soft peaks. Fold in 0.5 cup raspberry coulis until just combined—this adds a bright, fruity contrast to the rich chocolate. Spoon the whipped cream mixture over slices of cake and garnish with an extra pinch of flaky sea salt for a sophisticated finish. The coulis should be evenly distributed, adding a pop of color and acidity that cuts through the richness.
Slice the cake into 8 servings and serve immediately. Each slice should reveal dense, fudgy layers with a crackly top and a clean break. The whipped cream and coulis should complement the chocolate without overpowering it, creating a balanced bite. This cake holds up well for 2-3 days at room temperature, making it perfect for meal prep or gifting.
Pro Tips For Making America'S Test Kitchen Flourless Chocolate Cake
- Melt Chocolate Slowly: I learned this the hard way—dumping chopped chocolate into the butter and sugar at high heat turns it grainy. Instead, melt the butter first, then whisk in the chocolate in three additions, letting each fully dissolve before adding more. The goal is a smooth, glossy paste, not a lumpy mess.
- Whip Egg Whites Cold: The recipe calls for room-temperature egg whites, but I’ve found mine whip faster and stiffer when they’re just chilled—not cold, but not warm either. Pop them in the fridge for 10 minutes before whipping, and you’ll avoid overworking them (which makes them flat) or struggling with sluggish volume.
- Skip the Overmixing: Folding in the egg whites is where most people go wrong. The second you see streaks of white disappear, stop. Overmixing deflates the air and makes the cake dense. Use a spatula to gently cut through the batter and fold—yes, it’ll look uneven, but that’s how you get a light, airy crumb.
- Bake Until Springy: The cake’s edges might look set before the center is ready, but that’s a trap. Press the center lightly—it should spring back slowly, not bounce. If it’s still jiggly after the recipe’s time, tent with foil and bake 5 more minutes. Rushing this step means a gummy middle that ruins the whole thing.
Flavor customization for this dish
Spiced Orange Twist
Infuse your cake with warmth by adding 1 tbsp orange zest and 1 tsp grated orange peel to the chocolate mixture before cooling. The citrus brightens the deep cocoa flavor, creating a sophisticated balance.
I also add ½ tsp ground cinnamon for extra depth—this works especially well with Valrhona Guanaja chocolate. Garnish with a thin orange slice for visual appeal. 🍊
Espresso Boost
For coffee lovers, stir 1 tbsp instant espresso powder into the cooled chocolate mixture. This intensifies the chocolate flavor and adds a subtle bitterness that pairs beautifully with the richness.
I recommend Starbucks Via for consistent results. Serve with a dollop of vanilla bean ice cream for a decadent contrast. ☕
Salted Caramel Swirl
Create a luxurious version by folding ½ cup salted caramel sauce (store-bought or homemade) into the batter before baking. Use a skewer to swirl the caramel throughout the batter for marbled effect.
Top with extra flaky sea salt after baking for a gourmet finish. I love Trader Joe's salted caramel sauce for its perfect balance of sweetness and salt. 🍯
Peppermint Mocha
Add a festive twist by incorporating 1 tsp peppermint extract (like Ghirardelli) into the egg whites before folding. For extra crunch, sprinkle crushed candy cane pieces on top before baking. This version is perfect for holiday celebrations and pairs wonderfully with peppermint whipped cream. 🎄
Chai-Spiced Version
Transform your cake into a spiced delight by adding ½ tsp ground cardamom, ¼ tsp ground cloves, and ½ tsp ground ginger to the chocolate mixture. These warm spices create a comforting, aromatic profile that works beautifully with Ghirardelli 60% cocoa chocolate.
Serve with a sprinkle of toasted coconut flakes for texture contrast. 🌿
White Chocolate Swirl
For a marbled effect, melt 4 oz white chocolate separately and gently fold it into the batter in thin ribbons. The contrast of dark and white chocolate creates a stunning visual and flavor experience.
I use Ghirardelli white chocolate baking bars for the best results. Garnish with white chocolate shavings for extra elegance. ✨

Frequently asked questions
Why does this flourless chocolate cake use egg whites instead of whole eggs?
The recipe relies on egg whites to create a light, airy structure without adding moisture that would make the cake dense. Whole eggs would introduce too much liquid, resulting in a heavier texture. The stiff peaks provide the lift needed for that signature fudgy yet tender crumb. This method also eliminates the need for flour to bind the ingredients.
Can I substitute aquafaba for egg whites in this recipe?
Yes, but with adjustments! Use a 1:1 ratio of aquafaba (chickpea brine) to egg whites, but whip it to stiff peaks first. You may need to add ¼ tsp cream of tartar to stabilize the foam. The texture will be slightly lighter, but still delicious. For best results, use a high-quality aquafaba with no added salt or seasonings.
What's the best way to test if the cake is fully baked?
Insert a toothpick into the center—it should come out with moist crumbs (not wet batter). The cake will look slightly underdone when you take it out, but it continues cooking as it cools. Tap the top gently: if it springs back slightly, it's done. Overbaking will make it dry, so trust the toothpick test more than appearance.
How do I prevent the cake from cracking on top?
Cracking usually happens from uneven baking or sudden temperature changes. Ensure your oven is fully preheated to 350°F and the batter is at room temperature before baking. Avoid opening the oven door during the first 20 minutes. If cracks appear, they're mostly cosmetic—just cover them with whipped cream or ganache!
Can I make this cake in a different pan size?
For an 8-inch round pan, this recipe is perfect. For a 9-inch pan, reduce baking time by 5 minutes (30-35 minutes total). For a 6-inch pan, increase time by 5-10 minutes (40-45 minutes). Adjust accordingly, but always use the toothpick test. The cake should be fully set before removing from the oven.
