Sunken Black Forest Cake: A Decadent Chocolate Cherry Tradition
A lush, flourless chocolate cake crowned with whipped cream and boozy cherries—a modern riff on the classic Black Forest.
If you crave the exquisite pairing of chocolate and cherries, the sunken black forest cake offers a minimalist yet utterly indulgent twist on the classic German Schwarzwälder Kirschtorte. Rather than multiple layers, this cake features a single, flourless base with a lush, creamy topping and bright cherry preserves. Its rich flavor, dramatic appearance, and manageable steps make it a favorite for celebrations or a cozy weekend treat.
The Black Forest Cake Origins
The traditional Black Forest Cake hails from Germany, known for its layers of chocolate sponge cake, whipped cream, and boozy sour cherries. While its construction can demand finesse, this sunken interpretation keeps things simple: one chocolate cake layer, topped with clouds of whipped cream and tangy cherry preserves—often laced with kirsch (cherry brandy).
- Flourless chocolate cake as the base, providing deep, rich flavor and a slightly sunken center.
- Whipped cream for softness and contrast.
- Cherry preserves, spiked with kirsch, for brightness and traditional Black Forest flair.
Recipe: Sunken Black Forest Cake
This recipe uses straightforward methods and accessible ingredients—no need for advanced cake decorating skills. Here are the key ingredients and steps:
| Ingredient | Amount |
|---|---|
| Unsalted butter | 12 tablespoons (170g) |
| Semi- or bittersweet chocolate chips or chopped chocolate | 12 ounces (340g) |
| Eggs | 6 large, separated |
| Lemon juice OR vinegar (white or cider) | 1/2 teaspoon |
| Granulated sugar | 3/4 cup (150g), divided |
| Kosher salt | 1/2 teaspoon |
| Heavy cream | 3/4 cup (180ml) |
| Vanilla extract | 2 teaspoons |
| Cherry preserves | 1/2 cup (120ml) |
| Kirsch (optional) | 2 tablespoons |
Step-by-Step Instructions
- Prepare your pan: Heat oven to 350°F (175°C). Coat a 9-inch round pan with nonstick spray, line with parchment.
- Melt chocolate and butter: Combine butter and chocolate in a heatproof bowl over simmering water, melt until smooth. Let cool slightly.
- Whip egg whites: Beat whites in a mixer or bowl. Once foamy, add lemon juice/vinegar and half the sugar, whipping to soft peaks (billowy, just glossy).
- Beat yolks and sugar: In a separate bowl, beat yolks, remaining sugar, and salt until thick and pale. Slowly pour in chocolate-butter mixture, mixing well.
- Fold whites into batter: Gently fold one-third of egg whites into chocolate mixture to lighten; fold in remaining whites in two batches, taking care not to deflate the batter.
- Bake: Transfer batter to prepared pan. Bake until center puffs and a toothpick comes out with a few dry crumbs—about 35–40 minutes. Avoid overbaking; edges should not smell burnt.
- Cool: Let cake cool completely on rack. Center will sink. Run a knife around edge to loosen; invert onto rack, then back to plate.
- Whip cream and finish: Beat cream, sugar, and vanilla until medium peaks (fluffy but holds shape). Combine preserves and kirsch in a bowl.
- Top the cake: Spread whipped cream over sunken center; spoon cherry preserves mixture over cream.
- Serve: Slice into wedges and serve. Best texture is at room temperature with chilled cream and cherries.
Tips for Success and Ingredient Variations
- Egg white technique: For a moist cake, beat whites only to soft peaks—overbeating leads to dryness.
- Chocolate quality: Use high-quality semisweet or bittersweet chocolate for depth. Avoid milk chocolate as it may be too sweet.
- Sour cherry preserves: Sour (rather than sweet) cherry preserves evoke the traditional flavor. If unavailable, regular cherry preserves work, or use canned cherries reduce with sugar and lemon juice.
- Alcohol substitution: Kirsch offers authentic taste, but a spoonful of lemon juice and water or light rum works for a non-alcoholic version.
- Make-ahead: Cake keeps covered in fridge for up to three days. For best presentation, add cherries just before serving.
Simple Variations to Elevate the Cake
- Add shaved chocolate: Sprinkle dark chocolate shavings over the whipped cream for extra flair.
- Spice it up: Blend a pinch of cinnamon or espresso powder into the chocolate for warmth and complexity.
- Alternative toppings: Substitute cherry preserves with raspberry or blackberry for a different tartness profile.
Serving Suggestions
This cake shines as a showpiece dessert, but its rustic look means fuss-free slicing and plating. Serve with:
- Coffee or espresso—to complement the chocolate’s richness.
- Vanilla ice cream—for a cold, creamy contrast.
- Extra cherries or berry compote—if you crave more fruit flavor.
Make-Ahead and Storage
Sunken black forest cake is ideal for prepping ahead:
- Bake the cake a day in advance—store covered at room temperature.
- Whipped cream and cherry topping—prepare and assemble just before serving for freshest appearance.
- Leftovers—keep well in the fridge up to three days. The cherry-cream topping might lose visual appeal but remains delicious.
Smitten Kitchen Notes & Troubleshooting
- If using a springform pan, line carefully and wrap in foil if worried about leaks. Remove sides after partial cooling for best texture.
- Inverting the cake twice—once to remove parchment, again to plate—helps maintain shape despite its delicate, sunken center.
- Overwhipping cream can lead to a grainy texture; err on the side of soft-to-medium peaks.
- If out of kirsch, other clear spirits or citrus juices offer a lively kick to the cherry topping.
Why a “Sunken” Cake?
The sunken appearance is not an error—it’s the hallmark of flourless chocolate cakes. Without flour for structure, the cake puffs up dramatically then deflates, leaving a decadently moist, fudgy center that’s perfect for cradling cream and fruit. This distinctive look also offers excellent presentation—a rustic yet elegant centerpiece.
Nutrition Highlights
This cake is naturally gluten-free. With no flour, it relies on eggs for structure and richness. A moderate sugar content and pure ingredients make it a treat that’s indulgent but easy to enjoy in moderation.

Frequently Asked Questions (FAQs)
Q: Can I make this cake without alcohol?
A: Yes. Substitute kirsch with water and lemon juice, or omit entirely. The cherries will still provide lovely flavor.
Q: My cake didn’t sink—did I do something wrong?
A: The degree of sinking depends on egg beating and baking time. Slight sinking is expected, but if yours stayed puffy, it may be slightly overbaked or the eggs were too stiff.
Q: Can I use frozen or fresh cherries?
A: Yes. Cook pitted cherries with sugar and a splash of lemon juice, simmer until thickened, and cool before topping the cake.
Q: Is it essential to use a springform pan?
A: No, a regular 9-inch cake pan works well if lined with parchment and greased thoroughly.
Q: Can the cake be frozen?
A: The chocolate base freezes well, but add whipped cream and preserves after thawing for best results.
