Ingredients You’ll Need
The beauty of a Classic Black Forest Cake Slice is in the balance of its components—each ingredient is simple, but when combined, they create magic. From glossy cherries to the richest cocoa, here’s how every element brings flavor, texture, and color to your delicious masterpiece.
- All-purpose flour: The backbone of our cake, providing the structure needed to support all those luscious layers.
- Granulated sugar: Sweetens the cake and helps keep it moist.
- Unsweetened cocoa powder: Brings that deep, chocolatey flavor which pairs so beautifully with cherries.
- Baking soda and baking powder: These leaveners give the cake its light, airy texture.
- Salt: Just a pinch lifts and balances all the sweet flavors.

- Eggs: Bind everything together and add beautiful richness.
- Vanilla extract: Enhances both the chocolate and cherry flavors.
- Hot water or coffee: Blooming cocoa with hot liquid unlocks the cake’s deepest chocolate notes.
- Cherries (fresh or frozen): The star ingredient! Their tart-sweet juiciness sets this cake apart.
- Cornstarch: Thickens the cherry filling so it won’t ooze out of your lovely slice.

- Powdered sugar: Sifted for a smooth, cloudlike frosting.

How to Make Classic Black Forest Cake Slice
Step 1: Prepare the Chocolate Cake Layers
Start by preheating your oven to 350°F (175°C) and prepping two 8-inch round cake pans with grease and flour. In a large bowl, whisk together your dry ingredients—flour, sugar, cocoa powder, baking soda, baking powder, and salt. Add the buttermilk, vegetable oil, eggs, and vanilla extract, then beat everything until smooth. Gradually incorporate hot water or coffee; your batter will be thin but that’s what makes this cake extra moist. Pour into the pans and bake for 30-35 minutes. When a skewer tests clean, let the cakes rest for 10 minutes before transferring to a wire rack to cool completely.
Step 2: Make Luscious Cherry Filling
In a medium saucepan, combine your cherries (no need to thaw if frozen), sugar, and cornstarch. Pour in cherry liqueur or water, then cook over medium heat, stirring constantly until thickened and just bubbling. This will seem a little loose at first but thickens as it cools—creating the perfect filling for your Classic Black Forest Cake Slice.
Step 3: Whip Up Chocolate Buttercream
With an electric mixer, beat softened unsalted butter until creamy and pale. Gradually add sifted powdered sugar and cocoa powder, alternating with milk or cream. Once you reach fluffy, spreadable perfection, beat in vanilla extract and a pinch of salt. Adjust the consistency as needed—add more sugar for structure or a splash more milk for silkiness.
Step 4: Assemble Your Masterpiece
Once your cakes are completely cool, carefully level the tops with a serrated knife if needed. Place the first cake layer on your platter, spread with a generous layer of chocolate buttercream, and pipe a ring around the edge to create a ‘dam.’ Spoon in the cooled cherry filling so it stays tucked inside. Top with the second cake layer and frost the entire cake with the remaining buttercream. For a pro finish, apply a crumb coat, chill, and then go over with a final, smooth layer.
Step 5: Prepare the Chocolate Ganache Drip
Once the cake is frosted, it’s time for drama! Combine chocolate chips and heavy cream in a microwave-safe bowl. Heat in short bursts, stirring after each, until melted and smooth. Let the ganache cool just enough so it drips but doesn’t run. Carefully spoon or pour along the cake’s top edge, allowing it to cascade randomly for a striking effect.
Step 6: Finish and Garnish
Complete your Classic Black Forest Cake Slice by artfully arranging fresh cherries and sprinkling chocolate shavings or curls over the top. Pop the masterpiece into the fridge for at least 30 minutes so the ganache sets up nicely before slicing. Admire your creation and get ready to wow everyone with each dramatic slice!
How to Serve Classic Black Forest Cake Slice
Garnishes
I always say you’re never fully dressed without something special on top! For the Classic Black Forest Cake Slice, garnish with plump fresh cherries with their stems and a generous sprinkle of chocolate curls or shavings. If you have edible gold leaf, a tiny flake here and there is swoon-worthy for special occasions.
Side Dishes
A slice this rich doesn’t need much alongside, but a scoop of vanilla ice cream or a dollop of whipped cream never hurts. If you’re celebrating, a small flute of sparkling wine or cherry cordial makes the whole moment feel even more festive—just perfect for pairing.
Creative Ways to Present
Take your Classic Black Forest Cake Slice to new heights by serving it deconstructed in glass jars, perfect for picnics or parties. Or, for a retro twist, cut the cake into squares and serve each piece on pretty doilies with a cherry on top. Individual mini cakes or cupcakes layered just like the big cake are always a huge hit at gatherings!
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftover Classic Black Forest Cake Slice, cover the slices tightly with plastic wrap or an airtight container and keep them in the fridge. The cake will stay moist and fresh for up to four days, and the flavors deepen over time—dare I say it might taste even better on day two!
Freezing
This cake freezes surprisingly well. Simply wrap individual slices in plastic and then foil, or whole (un-garnished) cakes with the same method. Store in the freezer for up to two months. Defrost in the fridge overnight or at room temperature for a few hours before serving.
Reheating
To enjoy that just-baked texture, allow your Classic Black Forest Cake Slice to come fully to room temperature before digging in. If you crave a slightly warm treat, microwave a slice for 8–10 seconds. Be sure not to overdo it or the buttercream and ganache will melt!
FAQs
Can I use jarred or canned cherries instead of fresh or frozen?
Absolutely! While fresh or frozen cherries provide the brightest flavor, jarred or canned cherries (drained well) work perfectly for the filling. You might want to reduce the added sugar just a bit, depending on how sweet your cherries already are.
Is it okay to substitute the cherry liqueur with something non-alcoholic?
Yes! You can use plain water or cherry juice in place of cherry liqueur without sacrificing that signature Classic Black Forest Cake Slice taste. The dessert will still be irresistibly delicious, just a little more family-friendly.
Can I make Classic Black Forest Cake Slice gluten-free?
You can! Swap the all-purpose flour for your favorite 1:1 gluten-free baking blend and keep an eye on your leavening agents and fillings for hidden gluten. The result is just as dreamy and decadent.
Will this recipe work as cupcakes?
It sure will. Just divide the batter among lined muffin tins and bake for 20–24 minutes, or until a toothpick emerges clean. Fill and frost as you would for the full cake, and you’ve got personal-sized Classic Black Forest Cake Slices.
Can I make the cake layers ahead of time?
Yes! Bake the chocolate layers a day or two in advance, wrap them tightly in plastic, and keep them at room temperature or refrigerated. They’re sturdy and get even more flavorful, making assembly a breeze when you’re ready.
Final Thoughts
Classic Black Forest Cake Slice is simply the kind of treat that creates memories—and smiles. From the lush cherry filling to the rich chocolatey layers, it’s a dessert that always impresses and never lasts long. I can’t wait for you to try it and make it your own signature celebration cake!
