Introduction to the Perfect Dark Chocolate Cake with Strawberry Buttercream
Dark Chocolate Cake with Strawberry Buttercream is more than just a dessert; it is a celebration of contrasting flavors that dance across the palate with every bite. There is something truly magical about the marriage of deep, bitter cocoa and the bright, sun-ripened sweetness of fresh strawberries. This recipe is designed for those moments when a standard cake simply won't suffice. Whether you are celebrating a milestone birthday, an anniversary, or simply a Tuesday that requires a bit of decadence, this cake is your answer. It is the kind of dessert that stops the conversation at the dinner table, leaving only the sound of clinking forks and appreciative sighs.
The secret to a truly spectacular Dark Chocolate Cake with Strawberry Buttercream lies in the quality of the ingredients and the precision of the method. We are not just making a cake; we are building layers of texture and flavor. The sponge is incredibly moist, thanks to the inclusion of sour cream and buttermilk, while the use of both special dark and unsweetened cocoa powder creates a complex chocolate profile that isn't overly sugary. When you top that rich base with a fluffy, fruit-flecked buttercream and a silky ganache drip, you achieve a level of bakery-style perfection in your own kitchen.
Why You’ll Love It
You will absolutely fall in love with this Dark Chocolate Cake with Strawberry Buttercream because it hits every sensory note.

Unlike some chocolate cakes that can feel heavy or dry, this one remains light yet deeply satisfying. Second, the strawberry buttercream is a game-changer. By using real, finely diced strawberries rather than just an extract, you get an authentic, vibrant flavor that perfectly cuts through the richness of the dark chocolate.
Furthermore, this Dark Chocolate Cake with Strawberry Buttercream is a visual masterpiece. The pink frosting against the dark sponge, topped with a glossy chocolate drip and fresh berries, makes it look like it came straight from a high-end patisserie.

Ingredients Deep Dive
To create the perfect Dark Chocolate Cake with Strawberry Buttercream, your pantry needs a specific set of high-quality components. We use three cups of all-purpose flour to provide the structure, balanced with three cups of sugar to ensure a soft crumb. The star of the show is the cocoa: a blend of one and a half cups of special dark cocoa and half a cup of unsweetened cocoa. This combination provides both the deep color and the robust flavor that defines a true dark chocolate experience. Baking powder and baking soda work together to give this cake its impressive lift.
For the wet ingredients, four large eggs and a half-cup of sour cream provide fat and protein for a silky mouthfeel. One cup of buttermilk adds the necessary acidity to react with the leavening agents, while a cup of warm water mixed with espresso powder 'blooms' the cocoa, unlocking its full aromatic potential. We also include Kahlua, which adds a subtle coffee-liqueur undertone that makes the chocolate pop. For the buttercream, unsalted butter and six cups of powdered sugar create the base, while half a cup of very finely diced strawberries adds the signature flavor. This recipe builds upon the foundation of our The Most Irresistible Easy Moist Chocolate Cake Recipe That Will Melt Your Heart.
Notes and Substitutions
If you do not have buttermilk on hand, you can make a quick substitute by adding a tablespoon of lemon juice or white vinegar to a cup of whole milk and letting it sit for five minutes. For the Kahlua, if you prefer an alcohol-free version, simply replace it with more strong coffee or additional buttermilk. When it comes to the strawberries in the buttercream, it is crucial to pat them dry after dicing to prevent the frosting from separating. For those curious about the science behind these ingredients, Chocolate Ganache and its emulsification process is a great area of study for aspiring bakers.
Equipment Needed
To ensure your Dark Chocolate Cake with Strawberry Buttercream turns out perfectly, you will need three 9-inch round cake pans. A stand mixer fitted with a paddle attachment is ideal for the buttercream to achieve that airy, whipped consistency. You will also need large mixing bowls, a sturdy whisk, a kitchen scale for precision, and an offset spatula for smoothing the frosting. Cooling racks are essential to prevent the cake layers from becoming soggy as they cool.
Instructions for Success
Creating this Dark Chocolate Cake with Strawberry Buttercream requires following a logical sequence of steps to ensure the batter is well-emulsified and the frosting is stable.
- Prep the Pans: Preheat your oven to 350°F (175°C). Spray three 9-inch cake pans with non-stick spray and line the bottoms with parchment paper for easy removal.
- Mix the Chocolate Base: In a large bowl, whisk together the flour, sugar, special dark cocoa, unsweetened cocoa, baking powder, baking soda, and salt. Ensure there are no large clumps of cocoa powder.
- Add the Wet Ingredients: In a separate bowl, mix the eggs, sour cream, buttermilk, oil, vanilla, and Kahlua. Slowly incorporate the warm water mixed with espresso powder. Combine the wet and dry ingredients just until smooth.
- Bake the Layers: Divide the batter evenly between the three pans. Bake for 25–35 minutes. A toothpick inserted into the center should come out with just a few moist crumbs.
- Cool Completely: Allow the cakes to cool in the pans for 20 minutes before transferring them to wire racks. They must be completely cold before you attempt to frost them.
- Prepare the Buttercream: Beat the softened butter until light and fluffy. Gradually add powdered sugar and vanilla. Gently fold in the finely diced, dried strawberries and heavy cream.
- Assemble the Cake: Place one layer on a stand, top with a generous amount of strawberry buttercream, and repeat. Frost the exterior smoothly using an offset spatula.
- Ganache and Garnish: Prepare the ganache by melting chocolate chips with heavy cream. Drip it over the edges of the Dark Chocolate Cake with Strawberry Buttercream and decorate with fresh berries.
Pro Tips for the Best Cake
When making Dark Chocolate Cake with Strawberry Buttercream, always ensure your eggs, buttermilk, and sour cream are at room temperature. This allows the batter to emulsify properly, leading to a more uniform crumb. Sifting your cocoa powder is another essential step to avoid bitter lumps in the sponge. For the buttercream, if you find it is too soft, refrigerate it for 15 minutes before piping. Lastly, for the most beautiful ganache drip, use a squeeze bottle to control the flow down the sides of the cake. This ensures that your Dark Chocolate Cake with Strawberry Buttercream looks as good as it tastes.
Serving, Storage & Variations
Serve your Dark Chocolate Cake with Strawberry Buttercream at room temperature for the best flavor profile. If you have leftovers, store them in an airtight container in the refrigerator for up to five days. Because of the fresh fruit in the buttercream, it is best not to leave the cake out in a warm room for too long. For a variation, you can try adding a layer of strawberry jam between the cake layers for an extra burst of fruitiness. You could even swap the ganache for a white chocolate version if you want a lighter aesthetic.

FAQs
Why do I need to add espresso powder to chocolate cake?
Espresso powder acts as a flavor enhancer for cocoa. It does not make the cake taste like coffee; instead, it deepens the chocolate notes, making the Dark Chocolate Cake with Strawberry Buttercream taste much richer.
Can I use frozen strawberries for the buttercream?
Yes, but you must thaw them completely and drain all excess liquid. Too much moisture will cause the strawberry buttercream to break or become soupy. Fresh strawberries are always preferred for the best texture.
How do I prevent my ganache from being too thin?
Ensure you are using a 2:1 ratio of chocolate to cream for a thicker drip. Let the ganache sit until it reaches a slightly thickened, lukewarm state before pouring it over your Dark Chocolate Cake with Strawberry Buttercream.
Do I have to use Kahlua in the batter?
The Kahlua is optional but highly recommended. It adds a sophisticated depth and moisture. If you prefer to avoid alcohol, you can substitute it with an equal amount of additional buttermilk or strong brewed coffee.
