Decadent Flourless Chocolate Cake

There's a moment that happens every time I make this cake—right when the chocolate and butter melt together, filling the kitchen with that unmistakable deep, luxurious aroma. I discovered this recipe during a dinner party when I'd promised dessert but forgotten to buy flour, and somehow those four eggs and quality chocolate became the most elegant solution. Now it's my secret weapon whenever I need to impress without the fuss.

My partner once described eating a slice of this cake as "chocolate that somehow also tastes like air," which I think is the best compliment I've ever received about anything I've baked. It was February, snowing outside, and we were trying to make a simple dinner feel special for our neighbors who had just moved in. That cake became the reason they stayed for three extra hours.

Ingredients

• High-quality dark chocolate (200 g, at least 70%): This is where the entire character of the cake lives—cheaper chocolate will taste waxy and flat, but good chocolate melts silky and tastes genuinely luxurious.
• Unsalted butter (120 g): Room temperature helps it incorporate smoothly with the chocolate, and unsalted lets the chocolate flavor shine without competition.
• Granulated sugar (150 g): This dissolves into the batter and creates that signature fudgy texture that somehow stays moist even after cooling.
• Fine sea salt (¼ tsp): A tiny pinch that makes you forget it's there but makes the chocolate sing louder than it would alone.
• Room temperature eggs (4 large): Cold eggs won't incorporate smoothly and can make the batter grainy—let them sit on the counter while you prep everything else.
• Pure vanilla extract (1 tsp): A whisper of vanilla deepens the chocolate without announcing itself.
• Fresh raspberries (125 g): The tartness is essential—it cuts through the richness and keeps each bite from feeling heavy.

Instructions

Set up your double boiler and melt the chocolate:

Fill a saucepan with water just enough that the bowl will hover above it without touching, then bring it to a gentle simmer. Chop your chocolate and butter into similar-sized pieces, add them to the heatproof bowl, and stir occasionally as they melt together into something glossy and smooth. You'll know it's ready when there are no visible chocolate specks left.

Build your base:

Remove the bowl from heat and let it cool for just a minute—you want it warm but not scorching hot. Whisk in the sugar and salt until everything is completely combined and the mixture looks thick and glossy, almost like it could hold its shape.

Add the eggs one at a time:

Crack an egg into the chocolate mixture, whisk it vigorously until it's completely incorporated and you can't see any streaks, then add the next egg. This takes patience, but each egg creates more volume and fluffiness in the batter. After all four are in, stir in the vanilla extract.

Prepare the pan and pour:

Grease your springform pan generously with butter or cooking spray, then line just the bottom with parchment paper. Pour the batter in and smooth the top with a spatula so it bakes evenly.

Bake until just-set:

The magic happens between 25 and 30 minutes—the edges should look set and pull slightly away from the sides, but the center should jiggle just barely when you gently shake the pan. A toothpick poked in the middle should come out with moist crumbs still clinging to it, not a clean toothpick and not raw batter either.

Cool completely before serving:

Leave the cake in the pan on a wire rack until it cools all the way down—this takes at least an hour, sometimes longer. The residual heat keeps cooking the interior, so patience here means the texture stays perfect.

Top and serve:

Once cool, run a thin knife around the edges to loosen it, then gently press the pan's release button and lift away the sides. Scatter the fresh raspberries across the top, dust lightly with icing sugar if you like, and let everyone watch you slice into it.

Save

There's something about serving a slice of this cake to someone who didn't know it was gluten-free until they finished eating it. Their surprise, that split second of "wait, really?" becomes proof that you don't need flour or complicated techniques to make dessert feel like an occasion.

The Secret of Flourless Chocolate Cake

The absence of flour isn't a limitation here—it's actually the whole point. Without flour to get in the way, the chocolate flavor becomes impossibly concentrated and the eggs create an incredibly tender crumb all by themselves. I used to think flourless cakes were intimidating, but the technique is simpler than most regular cakes because there's nothing to overwork or develop.

Why Raspberries Matter

If you top this cake with chocolate and call it done, it's delicious but it lands flat—all richness with nothing to catch your attention. But fresh raspberries create this moment of brightness that wakes up your palate and reminds you that you're eating something fresh and alive, not heavy. The tartness also makes you want another bite, which means everyone eats less overall but enjoys it more, which is the opposite of how rich desserts usually work.

Make It Your Own

This cake is beautiful as written, but it's also forgiving enough to bend to what you have in your kitchen. If raspberries aren't available or are too expensive, strawberries or blackberries work beautifully, or even fresh whipped cream and a dusting of cocoa powder if you want to keep it simple. The cake tastes just as good the next day—actually, it might taste better because the flavors settle and deepen—so you can make it ahead if hosting is stressing you out.

• If you want extra decadence, serve with a small scoop of vanilla ice cream that melts into the warm fudgy center.
• A tiny pinch of espresso powder whisked into the batter makes the chocolate flavor more intense without tasting like coffee.
• You can make this up to two days ahead; store it covered at room temperature and add the raspberries just before serving so they stay fresh.

Save

This cake has shown up on my table for anniversaries and apologies, for celebrations that needed to feel special and ordinary Tuesday nights that needed a little magic. It's proof that sometimes the most impressive desserts are the ones that taste like love but require very little else.
