Flourless Chocolate Cake (Kosher for Pesach)

There are Pesach desserts that apologize for themselves—dry matzo meal cakes, meringues that crumble to dust, sponge cakes that taste like compromise. And then there is flourless chocolate cake, which is not a Passover workaround but one of the finest desserts in the entire French pastry canon, a cake that happens to contain no flour at all. This is the cake that elite restaurants serve year-round for $18 a slice. The fact that it is also perfectly kosher for Pesach is, as they say, a beautiful coincidence.

The secret is absurdly simple: a staggering amount of good chocolate, eggs, and fat. That is it. No flour, no starch, no leavening of any kind. The eggs provide all the structure—whipped whites create a delicate lift, while the yolks emulsify with the melted chocolate and coconut oil into something impossibly smooth and rich. The result is a cake with the density of a truffle, the sheen of a ganache, and a texture that falls somewhere between a soufflé and fudge.

This version is pareve, using refined coconut oil in place of butter so it can follow any meal—meat or dairy. The coconut oil (refined, not virgin) contributes the same richness and mouthfeel as butter without any coconut flavor. If you prefer a dairy version, butter is noted as a variation below, and it is magnificent. But the pareve version is not a compromise. It is, honestly, just as good, because when your cake is 60% dark chocolate by weight, the fat is a supporting player, not the star.

Make this cake a day ahead. It improves overnight as the texture sets and the chocolate flavor deepens. Serve it barely warm or at room temperature with a dusting of cocoa powder, a spoonful of whipped cream (for dairy meals), or simply on its own. It needs nothing else. This is the one Pesach dessert that will make your guests forget they are eating a holiday-restricted menu.

What Makes This Recipe Special

• Zero flour, zero compromise — This is not a Pesach adaptation; flourless chocolate cake is a classic French dessert that never contained flour in the first place
• Restaurant-quality simplicity — Only six ingredients, no special techniques, no Pesach substitution ingredients. What you taste is pure chocolate
• Pareve elegance — Refined coconut oil delivers butter-like richness without dairy, making this cake the perfect finale to any Seder meal

Instructions

Step 1: Prepare the Pan

Preheat oven to 165°C (325°F). Grease a 23 cm (9-inch) round springform pan with coconut oil. Line the bottom with a circle of parchment paper and grease the parchment. Dust the sides lightly with cocoa powder, tapping out the excess. This prevents sticking without adding flour.

Step 2: Melt the Chocolate and Fat

Chop the chocolate into small, uniform pieces (about 1 cm). Place the chocolate and coconut oil in a large heatproof bowl set over a pot of barely simmering water (double boiler). The bowl should not touch the water. Stir gently with a spatula until completely melted and smooth. Remove from heat and let cool for 5 minutes—the mixture should be warm but not hot to the touch. Alternatively, microwave in 30-second intervals, stirring between each, until smooth.

Step 3: Add the Egg Yolks

Whisk the egg yolks with 100g (½ cup) of the sugar until slightly thickened and pale, about 1 minute. Remember: each egg must be cracked individually into a clear glass and checked for blood spots before separating. Add the vanilla extract and salt. Pour the yolk mixture into the warm (not hot) chocolate and stir until completely smooth and glossy. Sift in the cocoa powder and fold until no streaks remain.

Step 4: Whip the Egg Whites

In a perfectly clean, dry bowl (any trace of fat will prevent the whites from whipping), beat the egg whites with an electric mixer on medium speed until foamy. Increase speed to high and gradually add the remaining 50g (¼ cup) sugar, one tablespoon at a time. Continue whipping until the whites hold firm, glossy peaks—when you lift the whisk, the peak should stand upright with just a slight curl at the tip. Do not over-whip to a dry, grainy stage.

Step 5: Fold the Whites into the Chocolate

Scoop about one-third of the whipped whites into the chocolate mixture. Stir vigorously—this first addition lightens the batter and sacrifices some air intentionally to make folding easier. Add the remaining whites in two additions, using a large spatula to fold gently: cut down through the center, sweep along the bottom, fold over the top. Rotate the bowl a quarter turn and repeat. Continue until no white streaks remain, but stop immediately once incorporated. The batter should be airy, mousse-like, and voluminous.

Step 6: Pour and Bake

Pour the batter into the prepared pan. It should fill the pan about two-thirds full. Gently smooth the top with a spatula. Bake at 165°C (325°F) for 30–35 minutes. The cake is done when the top is set and slightly cracked, the edges have pulled away from the pan about 3 mm, and a toothpick inserted in the center comes out with moist crumbs (not wet batter). The center will jiggle very slightly—this is correct. It firms as it cools.

Step 7: Cool in the Pan

Place the pan on a wire rack and let cool completely in the pan, at least 1 hour. The cake will sink slightly as it cools—this is normal and expected. The top may crack; this is the signature look of a flourless chocolate cake. Do not panic. Once fully cooled, run a thin knife around the edge and release the springform ring. If desired, invert onto a serving plate and peel off the parchment for a smooth top, then invert again. Or serve with the crackled top facing up—it is beautiful either way.

Step 8: Finish and Serve

Just before serving, dust the top with cocoa powder or powdered sugar through a fine-mesh sieve. For a clean pattern, lay a doily or stencil on the surface before dusting. Serve at room temperature or barely warm (10 seconds in the microwave per slice revives the fudgy center beautifully). Garnish with fresh berries if desired. For dairy meals, a dollop of lightly sweetened whipped cream is the classic accompaniment.

Storage & Make-Ahead

• Room temperature: Up to 2 days in an airtight container or wrapped in plastic. The texture is best at room temperature.
• Refrigerated: Up to 1 week, tightly wrapped. Bring to room temperature for 30 minutes before serving, or warm individual slices briefly in the microwave.
• Frozen: Up to 3 months. Wrap the whole cake (or individual slices) tightly in plastic wrap, then foil. Thaw overnight in the refrigerator.
• Make-ahead for Pesach: This cake is best made 1 day before serving. The texture sets beautifully overnight and the chocolate flavor deepens. Bake up to 3 days ahead and refrigerate, or up to 1 month ahead and freeze. Dust with cocoa powder just before serving.

Troubleshooting

Frequently Asked Questions

Why is the bracha Shehakol and not Mezonot?

The bracha on cake is typically Mezonot because cake is made from one of the five grains (wheat, barley, spelt, oat, rye). This flourless chocolate cake contains no grain whatsoever—no flour, no matzo meal, no matzo cake meal. When the primary ingredient is chocolate (derived from cacao beans), the appropriate bracha is Shehakol. This is the consensus of major poskim. The after-bracha is Borei Nefashot.

Can I use butter instead of coconut oil?

Yes, and the result is exceptional. Substitute 115g (1 stick / ½ cup) unsalted butter, certified Kosher for Passover, for the coconut oil. The butter version has a slightly richer mouthfeel and a more classic French patisserie character. The cake becomes dairy, so it cannot be served after a meat meal. Label it clearly for kashrut purposes, especially on a communal Pesach dessert table.

What chocolate percentage should I use?

Between 60% and 70% cacao is ideal. Below 55%, the cake will be overly sweet with less chocolate intensity. Above 72%, the bitterness can be overwhelming and the texture becomes less smooth because of the reduced cocoa butter. A 62–66% chocolate hits the sweet spot—rich, complex, and deeply chocolatey without being austere. Avoid chocolate chips, which contain stabilizers that prevent proper melting.

Why does the cake crack on top?

Cracking is the signature appearance of a flourless chocolate cake—it happens because the whipped egg whites create a soufflé-like top that sets in the oven, then the denser interior contracts as it cools. This is not a defect; it is how the cake is meant to look. A dusting of cocoa powder makes the cracks look intentional and elegant. If a smooth top is essential for presentation, invert the cake and serve the flat bottom as the top.

Is this cake gluten-free?

Yes, this cake is naturally gluten-free as it contains no flour or grain products. However, for guests with celiac disease or serious gluten sensitivity, verify that all ingredients (especially chocolate and cocoa powder) are certified gluten-free, as cross-contamination during manufacturing is possible. A product that is Kosher for Passover is not automatically gluten-free—matzo products, for example, are KFP but contain gluten.
