Equipment

1 Electric mixer
1 large mixing bowl
1 8-inch cake pan

Ingredients

14 ounces semisweet or dark chocolate (50–60% cocoa) chopped into equally-sized pieces
1/2 cup unsalted butter
6 largs eggs room temperature

Instructions

Preheat the oven to 325°F / 165°C. Line the bottom of an 8-inch round pan with parchment paper. Brush the sides lightly with neutral oil, then dust with cocoa powder and tap out any excess. Set the pan aside.
Bring a kettle of water to a boil.
Place the chopped chocolate and butter in a heatproof bowl. Melt gently using a double boiler or microwave in 20–30 second intervals, stirring between each interval, until completely smooth.
Set aside and let the mixture cool until warm but not hot to the touch.
1/2 cup unsalted butter, 14 ounces semisweet or dark chocolate (50–60% cocoa)
Crack the eggs into a large mixing bowl and whisk until pale, foamy, and slightly thickened. The eggs should look airy but still fluid. These small air bubbles are what help the cake rise, so avoid over-whipping.
6 largs eggs
Add about ¼ cup of the beaten eggs to the chocolate mixture and fold with a spatula until smooth. This will help temper the mixture.
Pour the chocolate mixture into the remaining eggs and gently fold with a spatula, scraping the bottom and sides of the bowl, until just combined.
Fold rather than stir to keep the small air bubbles intact, which helps the cake bake up taller and prevents it from becoming dense.
Pour the batter into the prepared pan and tap the pan very lightly on the counter once or twice. This helps release any large air bubbles that could expand in the oven and cause the cake to deflate or bake unevenly, without disturbing the smaller bubbles that give the cake structure.
Place the cake pan inside a larger roasting pan and carefully pour the boiling water into the roasting pan until it reaches halfway up the sides of the cake pan.
Transfer to the oven and bake for 40–50 minutes without opening the oven door. The cake is done when the edges are set, the center jiggles slightly when gently shaken, and the surface looks smooth and matte.
A toothpick inserted near the center should come out with moist crumbs, not liquid batter.
Turn the oven off, crack the oven door open slightly using a wooden spoon to keep the door open, and let the cake sit inside for 15 minutes.
Remove the pan from the oven and place it on a rack. Let the cake cool completely in the pan, then cover and refrigerate for at least 2 hours.
Run a thin knife around the edge of the cake, release it from the pan, and serve chilled or at cool room temperature.
Optional: Shave chocolate on top or use chocolate chips for decoration.

Notes

Expert Tips

These tips make a big difference in this ingredient chocolate cake recipe and help you get a smooth, rich chocolate cake every time.

Chocolate choice matters more here than in most cakes. Use good-quality chocolate in the 50–60% range for balance and better flavor
Room temperature ingredients blend more smoothly and keep the batter from turning grainy
Whisking the eggs correctly is the easiest way to give this ingredient cake lift without flour. Do not over-whip!
Fold the egg gently with a spatula rather than stirring, so the batter stays light and stable
Light tapping before baking removes large air pockets that can cause uneven baking
The water bath keeps the heat gentle and steady for a smooth top, so don't skip it!
Slow cooling helps the cake hold its shape without cracking, so do it gradually.
Chill before serving so the texture sets properly

Frequently Asked Questions

Why did my cake sink in the middle?

Flourless cakes naturally settle slightly, but excessive sinking is usually caused by over-whipping the eggs, stirring instead of folding, skipping the water bath, or removing the cake from the oven too quickly. Cooling slowly helps prevent this.

Can I use darker chocolate, like 70% or higher?

You can, but the cake will be much less sweet and more intense since there is no added sugar. For best results and broad appeal, chocolate in the 50–60% range is recommended.

Why is my cake dense or heavy?

This usually happens when the egg mixture is deflated during mixing. Make sure to fold gently, not stir, once the chocolate is added, and avoid over-mixing.

Can I skip the water bath?

Technically, yes, but the cake is far more likely to crack, bake unevenly, or collapse. The water bath is one of the most important techniques for a smooth, professional-looking result.

How do I know when it’s done baking?

The edges should be set, the center should jiggle slightly when the pan is gently shaken, and the surface should look matte, not wet. A toothpick near the center should come out with moist crumbs, not liquid batter.

Does this cake need to be refrigerated?

Yes. Chilling allows the structure to fully set and gives the best texture. The cake slices cleanly and tastes richer once cooled.

Can I make this ahead of time?

Yes. This cake is ideal for making a day ahead. Store it covered in the refrigerator and bring it to cool room temperature before serving, if desired.

Why does this cake not taste like a regular cake?

This is a flourless chocolate cake, closer in texture to a baked chocolate truffle or dense brownie. The richness comes from technique and ingredients rather than flour or sugar.

How should I store this chocolate cake?

Store the cake covered in the refrigerator. Because it’s flourless and rich in chocolate and eggs, refrigeration helps the cake hold its structure and keeps the texture fudgy rather than soft or greasy.

Properly stored, it will keep well for up to 4 days. For the best flavor and texture, let the cake sit at room temperature for 15–20 minutes before serving.

Can I freeze this cake?

Yes, this cake freezes very well. Once fully cooled, wrap it tightly in plastic wrap, then wrap again in foil or place it in an airtight freezer-safe container. Freeze for up to 2 months.

Thaw overnight in the refrigerator, still wrapped, to prevent condensation from forming on the surface. This slow thaw preserves the smooth top and dense, creamy texture.
