Ingredients

This cake is a testament to the power of fundamental flavors, brought together in a way that celebrates their inherent richness.

1 ¼ cups whole almonds (about 6–7 oz.)
1 cup sugar, divided
6 ounces bittersweet chocolate, coarsely chopped
½ cup unsweetened cocoa powder
½ cup freshly squeezed orange juice
2 teaspoons fresh grated orange peel
6 large eggs, separated
1 vanilla bean, split lengthwise (or 1 tsp vanilla extract)
¼ teaspoon salt

Equipment Needed

A few key tools will ensure this cake comes together beautifully:

Food processor
Small bowl
Medium bowl
Large bowl (at least two, preferably three for egg whites)
Electric mixer (handheld or stand mixer)
10-inch springform pan
Rubber spatula
Wire rack
Oven

Instructions

The process is methodical, but each step builds upon the last to create a truly remarkable cake.

Preheat your oven to 350 degrees F (175 degrees C). This is a crucial first step to ensure even baking. Once preheated, prepare your springform pan. Brush the bottom of a 10-inch springform pan generously with butter or margarine. This will help prevent sticking and ensure the cake releases cleanly.
Prepare the almond and chocolate base. In the bowl of a food processor, combine the whole almonds and ¼ cup of the sugar. Process until the almonds are finely ground. You want a texture that’s almost like coarse flour. Then, add the coarsely chopped bittersweet chocolate to the food processor; blend until the chocolate is also finely ground. It’s important to get these components well-integrated at this stage.
Create the orange-cocoa mixture. In a small bowl, whisk together the unsweetened cocoa powder, freshly squeezed orange juice, and fresh grated orange peel until smooth. Ensure there are no lumps of cocoa powder remaining. This vibrant mixture will infuse the cake with a beautiful citrus aroma and a deep chocolatey undertone.
Begin the egg yolk mixture. In a medium bowl, combine the egg yolks and ½ cup plus 2 tablespoons of sugar. If you are using a vanilla bean, scrape the seeds from the split vanilla bean directly into the yolk mixture. If using vanilla extract, you’ll add that later.
Whip the egg yolk mixture. Using an electric mixer, beat the yolk mixture until it is very thick and pale yellow, which should take approximately 4 minutes. This process incorporates air and creates a stable base for the cake batter.
Incorporate the cocoa mixture. Beat in the prepared orange-cocoa mixture into the whipped egg yolk mixture until well combined.
Fold in the almond-chocolate mixture. Gently fold the ground almond-chocolate mixture into the yolk and cocoa batter using a rubber spatula. Be careful not to overmix; you want to maintain as much of the air incorporated in the yolks as possible.
Whip the egg whites. In a clean, dry large bowl (this is important for achieving maximum volume), beat the egg whites and salt with the clean beaters of your electric mixer until soft peaks form. This means when you lift the beaters, the egg whites form gentle peaks that curl over.
Gradually add the remaining sugar to the egg whites. Gradually add the remaining 2 tablespoons of sugar, beating continuously until the egg whites are stiff but not dry. Stiff peaks will stand up straight when you lift the beaters. If they look glossy and slightly curdled, they are overbeaten.
Fold the egg whites into the chocolate batter. This is a critical step for lightness. Fold the stiffly beaten egg whites into the chocolate batter in 3 additions. The first addition can be a bit more vigorous to lighten the batter, then fold the remaining two additions very gently. Use your spatula to cut down through the center of the batter, scrape along the bottom, and bring it up and over, turning the bowl as you go. Stop folding as soon as no streaks of white remain; overfolding will deflate the batter.
Transfer the batter to the prepared pan. Carefully transfer the batter to the prepared 10-inch springform pan. Spread it evenly with your spatula.
Bake the cake. Bake the cake in the preheated oven until a tester inserted into the center comes out clean, which should take approximately 40 minutes. Baking times can vary depending on your oven, so start checking around 35 minutes.
Cool the cake completely. Once baked, remove the cake from the oven and let it cool completely in the pan on a wire rack. This gradual cooling is essential for the cake’s structure.
Storage if making ahead. If making the cake a day ahead of time, cover it with foil and store it at room temperature. This allows the flavors to meld beautifully.

Expert Tips & Tricks

Finely Ground Almonds are Key: Ensure your almonds are truly finely ground in the food processor. Any large pieces can affect the texture of the final cake. If you don’t have a food processor, you can often buy almond flour or finely ground almonds.
Chocolate Quality Matters: With so few ingredients, the quality of your bittersweet chocolate will significantly impact the final flavor. Opt for a good quality chocolate with a cocoa percentage between 60-70% for a balanced richness.
The Art of Folding: Folding egg whites is an art form. Be patient and gentle. The goal is to incorporate the whites without knocking out all the air you’ve worked so hard to whip in. Think of it as a gentle embrace, not an aggressive mix.
Vanilla Bean vs. Extract: While the recipe specifies a vanilla bean, good quality vanilla extract is a perfectly acceptable substitute. Ensure you use the correct measurement if substituting.
Room Temperature Eggs: For the best volume when whipping egg whites, ensure they are at room temperature. This allows them to expand more easily.

Serving & Storage Suggestions

This flourless chocolate-orange almond cake is a showstopper on its own, its rich, dense texture and complex flavor profile needing little adornment. For an elegant presentation, dust it lightly with confectioners’ sugar just before serving, or serve it alongside a dollop of freshly whipped cream or a spoonful of bright raspberry coulis. The contrast of the slightly tart berries against the deep chocolate is simply divine.

Leftovers will keep beautifully. Cover the cake tightly with foil or plastic wrap and store it at room temperature for up to 2 days. If the weather is particularly warm or humid, or for longer storage, you can refrigerate it. It will keep well in the refrigerator for up to 4 days. Before serving from the refrigerator, allow the cake to sit at room temperature for about 30 minutes to an hour to soften slightly.

Variations & Substitutions

While this cake is perfection as is, here are a few ideas to explore:

Citrus Swap: If oranges aren’t your favorite, you could experiment with the zest and juice of lemons or even mandarins for a slightly different citrus profile.
Nutty Alternatives: While almonds are specified, you could try finely ground walnuts or pecans for a different nutty depth. Be mindful that the flavor profile will change.
Chocolate Intensity: For a more intense chocolate flavor, consider using a bittersweet chocolate with a higher cocoa percentage (e.g., 70-75%). Conversely, if you prefer a slightly sweeter cake, a 60% cocoa chocolate will work well.
A Touch of Spice: A pinch of cinnamon or a whisper of cayenne pepper, added with the cocoa powder, can add an unexpected warmth and complexity to the chocolate.

FAQs

Q: Why is this cake flourless?
A: This cake is flourless because it relies on ground almonds and eggs for its structure and texture, making it naturally gluten-free and creating a wonderfully dense and rich crumb.

Q: How can I ensure my egg whites reach stiff peaks?
A: Make sure your bowl and beaters are completely free of any grease or fat, and that the egg whites are at room temperature. Beating gradually with clean equipment is key.

Q: Can I make this cake without a springform pan?
A: While a springform pan is ideal for easy removal, you could try a regular round cake pan if you line it very thoroughly with parchment paper and grease it well. However, releasing the cake cleanly might be more challenging.

Q: My cake cracked on top, is that normal?
A: A slight crack on top is quite common with flourless chocolate cakes as they bake. It doesn’t affect the taste or texture and is often considered part of its rustic charm.

Q: How can I tell when the cake is done baking?
A: A cake tester inserted into the center should come out clean, meaning there is no wet batter attached. The edges should also start to pull away slightly from the sides of the pan.

Final Thoughts

This Flourless Chocolate-Orange Almond Cake is more than just a dessert; it’s an experience.
