Simple Method
The process is straightforward and very rewarding. You will melt chocolate, whisk eggs, and gently fold everything together. This method creates a cloud-like texture that sets beautifully in the oven.

Ingredients You’ll Need
Using high-quality chocolate makes a big difference in this simple recipe.
- 8 ounces bittersweet chocolate (60% cocoa), chopped
- 1/2 cup unsalted butter, cubed
- 5 large eggs, separated at room temperature
- 1/2 cup granulated sugar, divided
- 1 teaspoon vanilla extract
- 1/4 teaspoon kosher salt
- 1/4 teaspoon cream of tartar
- Cocoa powder for dusting
Step-by-Step
- Preheat oven to 325 degrees Fahrenheit and grease an 8-inch springform pan.
- Melt the chocolate and butter together using a double boiler or microwave in 30-second increments until smooth.
- In a large bowl, whisk egg yolks with 1/4 cup of sugar until pale and thickened.
- Slowly fold the melted chocolate mixture and vanilla extract into the egg yolk mixture.
- In a separate clean bowl, beat egg whites with salt and cream of tartar until soft peaks form.
- Gradually add the remaining 1/4 cup of sugar to the egg whites and continue beating until stiff, glossy peaks form.
- Gently fold one-third of the egg whites into the chocolate base to lighten the density.
- Fold in the remaining egg whites until no white streaks remain, taking care not to deflate the batter.
- Pour the batter into the prepared pan and bake for 35 to 40 minutes until the edges are set but the center remains slightly wobbly.
- Cool completely in the pan on a wire rack and dust with cocoa powder before serving.
Best Ways to Enjoy It
Serve this cake warm with a dollop of fresh whipped cream. A handful of tart raspberries adds a beautiful pop of color and flavor. It is a wonderful way to end a cozy holiday meal.
For a romantic date night, light a candle and serve small slices. You can even add a drizzle of salted caramel for extra indulgence. It is a dessert meant for sharing with people you love.
Keep It Fresh
Store any leftovers in the refrigerator for up to three days. Keep the cake tightly wrapped to maintain its moist and fudgy texture. It actually tastes wonderful when eaten cold straight from the fridge.
To reheat, place a slice in the microwave for ten seconds. This will bring back that soft, melt-in-your-mouth feel. You can also freeze individual slices for a quick chocolate fix later.
Tips for Best Results
- Use room temperature eggs for the best volume in your whites.
- Do not skip the cream of tartar as it stabilizes the foam.
- Avoid over-mixing when folding to keep the cake light and airy.
- Use a clean, grease-free bowl when whipping your egg whites.
- For the holidays, serve with a dusting of powdered sugar for snow.
- Check the cake early to ensure the center stays slightly wobbly.
- Use a high-quality bittersweet chocolate for the deepest flavor.
Ways to Switch It Up
- Add a teaspoon of espresso powder to enhance the chocolate flavor.
- Swap vanilla extract for almond extract for a nutty aroma.
- Top with toasted hazelnuts for a satisfying crunch in every bite.
- Serve with a scoop of vanilla bean ice cream while warm.
Common Questions
Can I make this cake ahead of time?
Yes, you can bake this cake a day in advance. Simply store it in the fridge and dust with cocoa powder just before serving. It is a great time-saver for holiday hosting.
What if I do not have a springform pan?
You can use a regular 8-inch cake pan lined with parchment paper. Make sure the paper hangs over the edges so you can lift it. This ensures your delicate cake stays perfectly intact.
Is this cake supposed to sink in the middle?
Yes, it is very common for this style of cake to sink. The slight crackling and dip create a rustic and beautiful look. It provides the perfect well for whipped cream and berries.
I hope this decadent cake brings a little extra sweetness to your winter evenings. It is a simple joy that makes every occasion feel special. Happy baking!
