Decadent Flourless Chocolate Cake

The first time I understood what made chocolate sing was watching my grandmother lean over a double boiler, dark chocolate melting into liquid silk while butter danced through it. She never wrote anything down, just knew by the smell and shine when it was ready. Years later, I realized that moment wasn't just about chocolate—it was about how patience and good ingredients could create something that felt almost alive on the tongue. That's what this cake is.

I made this cake for a dinner party once where someone mentioned offhandedly that they couldn't eat regular flour. Instead of scrambling for substitutes, I remembered my grandmother's method and thought, why not just skip the flour entirely? The room went quiet when people took their first bites, and someone asked if it was actually flourless or if I was joking. That silence before the questions came was its own kind of victory.

Ingredients

• Dark chocolate (70% or higher), 200g chopped: High quality matters here more than anywhere else in the recipe—the chocolate is the entire point, so it needs to taste good on its own. Look for bars you'd actually want to eat as candy.
• Unsalted butter, 120g cubed: Cubing it first means it melts evenly with the chocolate and you avoid any weird separated puddles.
• Granulated sugar, 150g: Dissolves completely into the batter and creates that glossy, thick texture that tells you everything is working.
• Fine sea salt, ¼ tsp: A small pinch that you won't taste directly but will make the chocolate flavor pop and deepen.
• Large eggs, 4 at room temperature: Cold eggs won't incorporate smoothly, so pull them out of the fridge while you're melting the chocolate—that's usually enough time.
• Pure vanilla extract, 1 tsp: A modest amount that whispers in the background rather than shouting over the chocolate.
• Fresh raspberries, 125g: The tartness and little pops of seeds give you something to bite into besides pure richness, plus they look beautiful.
• Icing sugar for dusting, optional: A light drift of powder that catches the light and makes the cake feel dressed up.

Instructions

Get your oven ready and prep your pan:

Preheat to 180°C (350°F) while you grease a 20cm springform pan and line just the bottom with parchment paper. This step takes two minutes but saves you from a cake that sticks and tears when you try to unmold it.

Melt chocolate and butter together:

Set a heatproof bowl over a pan of gently simmering water (the bowl shouldn't touch the water) and add the chopped chocolate and cubed butter. Stir slowly until everything melts into smooth, glossy liquid—this usually takes about 5 minutes and the whole kitchen smells like a chocolate factory. Let it cool for just a minute or two so the eggs don't scramble when they go in.

Build your batter base:

Whisk the sugar and salt into the warm chocolate mixture until you can't see any granules anymore. This is easier than it sounds and takes about a minute.

Add eggs one at a time:

Crack an egg into the chocolate, whisk it thoroughly until it's completely incorporated and the mixture looks shiny and thick, then add the next one. Do this four times, whisking well after each egg—rushing this step means lumpy batter that won't bake evenly.

Finish the batter:

Stir in the vanilla extract until it's evenly distributed, then pour everything into your prepared pan and smooth the top with a spatula so it bakes evenly.

Bake until the edges set:

Bake for 25-30 minutes—you're looking for the edges to be firm but the center to jiggle slightly when you gently shake the pan. A toothpick inserted in the middle should come out with a few moist crumbs clinging to it, not clean and not covered in wet batter.

Cool completely:

Leave the cake in the pan on a wire rack until it cools all the way down. This is important because the cake continues to set as it cools, and moving it too early means it falls apart.

Unmold and top:

Run a thin knife around the edge of the springform pan, release the sides, and slide the whole thing onto a serving plate. Top with fresh raspberries and dust lightly with icing sugar if you want it to look fancy.

There's a specific moment when someone cuts into this cake that reminds me why I love cooking at all—that first slice separates and reveals the fudgy interior, maybe a raspberry slides down the side, and suddenly you've created something that feels like a small luxury. That's worth the thirty minutes of effort.

Why This Cake Works Without Flour

Flour's job in baking is usually to provide structure, but this cake gets its structure from eggs and from the way chocolate and butter set as they cool. The eggs emulsify with the chocolate and create a stable base, while the high cocoa content keeps everything rich and cohesive. It's less like regular cake and more like a flourless brownie that somehow became elegant.

Serving Suggestions That Actually Make Sense

Serve this at room temperature, never cold straight from the fridge—the flavors open up when it's warm and the texture stays perfectly fudgy instead of becoming dense and heavy. A small scoop of vanilla ice cream next to it, or a dollop of whipped cream alongside, gives people something cool and creamy to cut through the richness. You could also serve it with a cup of strong coffee or hot tea, which sounds obvious but somehow people never expect it.

Making It Ahead and Storage

This cake actually improves after a day—the flavors deepen and the texture becomes more uniform—so bake it the day before you need it and store it covered at room temperature. You can also freeze it wrapped tightly for up to two weeks, then thaw it overnight before serving. It keeps for three to four days in a cake box or under a dome if you've got one.

• Don't refrigerate it unless your kitchen is very hot; cold temperatures dull the chocolate flavor and make the texture too firm.
• If you're doubling the recipe for a larger gathering, use a 23cm pan and add about five minutes to the baking time.
• You can make this hours ahead and add the raspberries just before serving if you want them to stay fresh and perky.

Pin It

This cake lives somewhere between a brownie and a mousse, rich enough to feel indulgent but simple enough that you'll want to make it again. When someone asks for the recipe, you get to tell them it's flourless and watch their expression shift from doubt to understanding once they taste it.
