Ingredients You’ll Need

Here’s what goes into this elegant, flourless dessert:

1/2 cup unsalted butter, cut into pieces
6 ounces semi-sweet baking chocolate, finely chopped
2/3 cup granulated sugar
2 teaspoons espresso powder
1 teaspoon vanilla extract
4 large eggs, at room temperature
1/3 cup unsweetened cocoa powder
1/4 teaspoon salt
1/2 teaspoon baking powder
Powdered sugar, for dusting
Fresh raspberries, for topping

Pro Tip: Use high-quality chocolate and cocoa powder for the best flavor. Brands like Ghirardelli or Guittard work beautifully here.

Step-by-Step Instructions

1. Prepare Your Oven and Pan

Preheat your oven to 350°F (177°C). Position a rack in the center and another on the bottom of the oven. Grease a 9-inch round cake pan, line the bottom with parchment paper, then grease the parchment as well.

2. Melt the Chocolate and Butter

Place butter and chopped chocolate in a large, heat-proof bowl. Microwave in 20-second increments, stirring between each, until smooth. Alternatively, use a double boiler. Let the mixture cool slightly for 2–3 minutes.

3. Mix in Flavor Boosters

Whisk in the granulated sugar, espresso powder, and vanilla extract until the mixture is smooth and glossy.

4. Add Eggs One at a Time

Whisk in the eggs, one at a time, ensuring each is fully incorporated before adding the next.

5. Fold in Dry Ingredients

Sift in cocoa powder, salt, and baking powder. Stir until just combined—avoid overmixing to maintain a smooth texture.

6. Bake in a Steam Bath

Pour batter into the prepared pan and smooth the top. Tap gently to release air bubbles. Set a metal roasting pan (not glass) filled with boiling water on the bottom oven rack—this creates steam for a silky texture. Place your cake on the center rack and bake for 28–32 minutes.

Check at 25 minutes. The edges should be set, and a toothpick should come out with moist crumbs or clean.

7. Cool and Invert Carefully

Let the cake cool in the pan for 10 minutes. Run a thin knife around the edge and carefully invert onto a serving plate. Let cool completely before topping.

8. Finish with Flair

Dust with powdered sugar and garnish with fresh raspberries for a beautiful and fresh contrast.

Kitchen Equipment You’ll Need

9-inch round cake pan
Parchment paper
Large heat-proof mixing bowl
Whisk
Microwave or double boiler
Fine mesh sieve or sifter
Roasting pan (for water bath)
Mixing spoon or spatula
Cooling rack
Sharp knife or offset spatula for release

Tips for Success

Don’t skip the water bath. It ensures even baking and prevents cracking.
Room temperature eggs incorporate more easily and help create a smoother batter.
Avoid overmixing after adding dry ingredients to maintain a fudgy texture.
Use good chocolate. This is a chocolate-forward cake—quality matters!
Let it cool completely before serving to get the best texture and flavor.

Storage Instructions

This cake stores beautifully:

Room Temperature: Store in an airtight container for up to 2 days.
Refrigerator: Keeps well for up to 5 days. Bring to room temperature before serving for the best texture.
Freezer: Wrap slices individually and freeze for up to 2 months. Thaw overnight in the fridge or at room temp for 2–3 hours.

Make-ahead tip: This cake tastes even better the next day after the flavors have had time to deepen.

Flavor Variations and Swaps

Add a liqueur: A splash of coffee liqueur (like Kahlúa) or orange liqueur (like Grand Marnier) adds a sophisticated twist.
Swap espresso powder: Use instant coffee if needed, or omit entirely for a milder flavor.
Top with ganache: Pour warm chocolate ganache over the cooled cake for an ultra-decadent finish.
Add spices: Try a pinch of cinnamon, cardamom, or cayenne for warmth and complexity.
Dairy-free? Use plant-based butter and dairy-free chocolate.

Serving Suggestions and Pairings

This cake shines on its own, but here are a few ways to enhance the experience:

Fresh fruit: Raspberries, strawberries, or even a cherry compote.
Whipped cream: Lightly sweetened whipped cream or coconut cream balances the richness.
Vanilla ice cream: A cold, creamy scoop melts deliciously over a warm slice.
Coffee or espresso: Perfectly complements the chocolate and deepens the flavor.
Red wine: Try a glass of port, cabernet sauvignon, or a bold merlot.
