Flourless Chocolate Cake (Passover-Friendly)

Flourless Chocolate Cake is the Passover dessert that genuinely doesn’t feel like a compromise. It’s deeply chocolatey, naturally gluten-free, and made with just a handful of pantry staples — semi-sweet chocolate, butter, eggs, and sugar — no flour needed.

Hey there, I’m Claire Whitmore — a pastry whisperer in Asheville, NC, where butter totally counts as self-care. This flourless chocolate cake recipe is one of those rare gems that’s both a showstopping Passover dessert and a year-round gluten-free cake that everyone at the table devours.

I first made this for a Seder dinner years ago, a little nervous about the cracking dome and the three-stage bake. Spoiler: that crack is totally normal, and once it collapsed and I smoothed it down, it looked almost intentional. Almost.

Flourless Chocolate Cake Ingredients

Here’s everything you need for this gluten-free cake — just six simple ingredients that work together beautifully.

For the chocolate base — semi-sweet chocolate and salted butter — you’ll want to melt these together gently so they’re silky smooth. For the egg components — yolks build richness while whipped whites create lift — make sure they’re at room temperature before you start.

Amount	Ingredient
10 oz	Semi-sweet chocolate, broken into pieces
1/2 cup	Salted butter, cut into 8 pieces (yes, real butter — margarine just doesn’t cut it here)
6 large	Eggs, separated, at room temperature
3/4 cup + 1/4 cup	Granulated sugar, divided (3/4 for yolks, 1/4 for whites)
2 tsp	Kahlua, dark rum, or creme de cacao (adds a lovely depth — don’t skip it)
1/2 tsp	Vanilla paste, or 1 tsp vanilla extract

Tools You’ll Actually Use

• 9-inch springform pan
• Parchment paper
• Microwave-safe bowl (for melting chocolate)
• Stand mixer or electric hand mixer
• Two large mixing bowls
• Rubber spatula (for folding)
• Oven thermometer (optional but helpful)

Step-by-Step Instructions for Flourless Chocolate Cake

Get ready — this gluten-free Passover dessert comes together in a few satisfying stages, and your kitchen is about to smell incredible.

Step 1: Set Up Your Oven

Place the oven rack on the lowest level. Preheat your oven to 375°F. Starting on the bottom rack helps the cake bake evenly from below, which matters with this dense batter.

Step 2: Prepare the Springform Pan

Coat the bottom and sides of a 9-inch springform pan generously with butter, margarine, or oil. Place a circle of parchment paper on the bottom of the pan — this is your insurance policy for a clean release later.

Step 3: Melt the Chocolate and Butter

Place the 10 oz of semi-sweet chocolate pieces and 1/2 cup of salted butter into a microwave-safe bowl. Microwave in 30-second intervals, stirring in between, until fully melted and glossy. Set aside to cool slightly.

Step 4: Beat the Egg Yolks

In a large mixing bowl (or stand mixer), beat the 6 egg yolks at high speed. Gradually add 3/4 cup of the granulated sugar. Continue beating until the mixture turns pale yellow and thick — this takes about 4 to 6 minutes and is worth every second.

Step 5: Combine Chocolate and Yolk Mixture

Add the melted chocolate-butter mixture to the pale egg yolk mixture. Beat until completely smooth and glossy, scraping down the sides as needed.

Step 6: Add the Flavor

Add the 2 tsp of Kahlua (or dark rum or creme de cacao) and 1/2 tsp vanilla paste (or 1 tsp vanilla extract). Beat until fully blended. Set this chocolate base aside while you work on the whites.

Step 7: Whip the Egg Whites

In a clean, separate medium bowl, beat the 6 egg whites at high speed until soft peaks form. Gradually add the remaining 1/4 cup of granulated sugar and continue beating until stiff — but not dry — peaks form. They should hold their shape but still look glossy, not grainy.

Step 8: Fold It All Together

Using a rubber spatula, gradually fold the whipped egg whites into the chocolate mixture in three additions. Go slow and gentle here — you want to keep as much air in those whites as possible. The batter will be light and a little airy.

Step 9: Fill the Pan and Bake

Pour the batter into your prepared 9-inch springform pan. Smooth the top lightly.

Step 10: The Three-Stage Bake

Bake at 375°F for 15 minutes. Then reduce the oven temperature to 350°F and bake for another 15 minutes. Reduce the temperature one more time to 250°F and bake for a final 30 minutes.

This gradual temperature drop is the secret to a fudgy, crack-friendly flourless chocolate cake. Don’t rush it.

Step 11: Rest in the Oven

Turn off the oven and prop the door open slightly. Let the cake rest inside the oven for 30 more minutes. This slow cooldown prevents sudden temperature shock, which helps the texture stay beautifully dense.

Step 12: Cool Completely

Take the cake out of the oven. Place a damp paper towel gently over the top for 5 minutes, then remove it. Let the cake cool completely at room temperature.

The dome will crack and collapse — this is completely normal and honestly part of the charm. You can gently press the top down to smooth it if you like.

Step 13: Serve

Remove the springform pan ring and transfer the cake to a serving platter. Serve at room temperature for the best texture and flavor. Slice and watch it disappear.

Claire’s Pro Tips for the Best Passover Dessert

A few little secrets make all the difference with this flourless chocolate cake. I’ve learned most of these the slightly embarrassing way, so you don’t have to.

Room-temperature eggs are non-negotiable. Cold egg whites won’t whip to their full potential. Pull your eggs out at least 30 minutes before baking.

Don’t over-beat the egg whites. Stiff but still glossy is your target. If they look dry and clumpy, they’ve gone too far — and folding them in will give you a grainy-textured cake.

Fold gently and patiently. This is not the moment to stir aggressively. Losing the air in those whites means losing the light, slightly airy structure that balances the dense chocolate base.

Don’t panic at the crack. The collapsing dome is not a mistake — it’s exactly what this Passover cake is supposed to do. Lean into it, dust it with cocoa powder, and call it rustic elegance.

Quick Fixes for Flourless Chocolate Cake

My cake sank too much in the middle

A little sinking is totally expected — that’s the nature of this cake. If it sinks dramatically and looks wet in the center, it likely needed a few more minutes in the oven. Use the 250°F bake stage to really let it set through.

The texture is too dense and fudgy

Check that your egg whites were beaten to stiff (not just soft) peaks before folding. Under-whipped whites don’t provide enough lift. Also make sure you’re folding in three additions, not all at once.

The cake is sticking to the pan

Always use parchment paper on the bottom — it’s the most important prep step for this recipe. Butter the sides generously too. If it’s still sticking, run a thin knife around the edge before releasing the springform.

The top looks dry and cracked before it’s done

That’s normal! The surface cracks are not a sign of overbaking. Trust the three-stage bake and the resting time in the oven — the interior will be perfectly moist.

My cake doesn’t look shiny or glossy

This usually means the chocolate and butter weren’t fully melted and blended before being added to the yolks. Make sure that mixture is completely smooth and slightly cooled (not hot) before mixing in.

Variations and Fun Twists on This Gluten-Free Cake

Once you’ve nailed the base recipe, this cake is your canvas. Here are a few ways to make it your own.

Add espresso powder: A teaspoon stirred into the melted chocolate deepens the chocolate flavor without making it taste like coffee. It’s a classic trick that really works.

Swap the Kahlua: Not a fan of coffee liqueur? Use dark rum, creme de cacao, or even a splash of orange liqueur for a citrusy twist. You can also leave it out entirely for an alcohol-free version — just add an extra 1/2 teaspoon of vanilla.

Top with ganache: Melt 1/2 cup of heavy cream with 4 oz of chopped semi-sweet chocolate and pour it over the cooled cake. It turns this into a truly next-level dessert.

Dust with cocoa or powdered sugar: Simple, beautiful, and it hides any imperfections in the top. A light dusting right before serving is all you need.

Serve with berries: Fresh raspberries or strawberries alongside a slice add brightness and color — perfect for a Seder table presentation.

Serving, Storage, and Reheating

This flourless chocolate cake is best served at room temperature — that’s when the texture is most fudgy and the chocolate flavor really sings. Pair it with a dollop of freshly whipped cream or a scoop of vanilla ice cream for a simple but stunning finish.

Store any leftovers (if you actually have leftovers, which I genuinely doubt) tightly wrapped or in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days — just bring it back to room temperature before serving.

To reheat, let refrigerated slices sit at room temperature for 30 to 45 minutes. You can also warm a slice in the microwave for 10 to 15 seconds, but be careful not to overheat — you want fudgy, not dry.

No-Waste Kitchen Magic

If you have a couple of leftover slices, crumble them into a bowl and layer with whipped cream and berries for an instant chocolate trifle. Nobody needs to know it was a “planned leftover.”

Extra egg whites? Make a batch of meringue cookies or a simple pavlova. And if you have leftover melted chocolate from the process, drizzle it over fruit for a fast dessert the next day.
