Kitchen Essentials You’ll Need
There is nothing fussy about baking this cake but having the right tools makes it feel more joyful and less like a kitchen scramble. A few well-chosen items keep the process calm and the results reliable. You want gear that helps with even baking, smooth frostings, and a neat finish.
- Two 9-inch round cake pans for even layers.
- Electric hand mixer or stand mixer for silky buttercream.
- Rubber spatula for folding and scraping every last bit of batter.
- Sifter or fine mesh for the dry ingredients so the cocoa blends without lumps.
- Cooling rack to cool layers completely and prevent soggy crumb.
- Instant-read thermometer helps with accurate doneness if you like precision.
Each of these tools matters because they keep textures consistent and speeds up small tasks. The mixer gives the buttercream that pillowy lift. The sifter and spatula keep the batter light. With these on hand you’ll feel confident rather than rushed, and that always shows in the final slice.
Why You’ll Love This Recipe
This cake gives you the best of two worlds. The cake itself is dark and velvety with a deep cocoa aroma that fills the kitchen as it bakes. The buttercream is bright and pink from real strawberry puree and it tastes like summer in every sweet bite. Combining rich chocolate with fresh strawberries is comforting and celebratory all at once.
You’ll love the texture contrast. The crumb is tender and moist because of the boiling water that blooms the cocoa into a glossy, chocolatey batter. The buttercream is smooth and creamy and adds a fruity lift that cuts through the richness. This is a cake that feels special but is simple enough for weeknight baking.
- Deep chocolate flavor with a light, moist crumb.
- Fresh strawberry buttercream that is not overly sweet.
- Simple pantry ingredients with a show-stopping result.
If you enjoy warm, nostalgic baking and desserts that receive the most appreciative smiles, then this Homemade Dark Chocolate Cake with Strawberry Buttercream will quickly become a recipe you reach for. For a different kind of chocolate treat to try another day, these hot chocolate cupcakes are a cozy option that play beautifully with the same chocolatey theme.
Homemade Dark Chocolate Cake with Strawberry Buttercream Ingredients
- 1 3/4 cups all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 2 cups granulated sugar
- 1 1/2 tsp baking powder
- 1 1/2 tsp baking soda
- 1 tsp salt
- 2 large eggs
- 1 cup whole milk
- 1/2 cup vegetable oil
- 2 tsp vanilla extract
- 1 cup boiling water
- 1 cup unsalted butter (softened)
- 4 cups powdered sugar
- 1/4 cup strawberry puree
- 1 tsp vanilla extract (for buttercream)
These are pantry-friendly ingredients you likely already have or can find easily. The boiling water is essential for bringing out the cocoa’s deep color and flavor. The strawberry puree should be smooth and flavorful for the best buttercream. If your strawberries are out of season, thawed frozen berries blitzed and strained work well too. Measure carefully and have the butter softened ahead of time for a silky frosting.
Step-by-Step Instructions
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. You want them evenly coated so the cakes release smoothly. Place the pans on the middle rack so heat circulates evenly.
In a large bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt. The dry mix should look uniform and free of lumps. Sifting brightens the cocoa and prevents streaks.
Add the eggs, milk, oil, and vanilla to the dry ingredients and mix until well combined. The batter will be thick and glossy at this point. Beat just until smooth so you do not overwork the gluten.
Gradually stir in the boiling water until the batter is smooth. It will thin dramatically and become very shiny as the hot water blooms the cocoa. This is normal and gives the cake its tender crumb.
Pour the batter evenly into the prepared pans. Fill each pan about two thirds full. Tap the pans lightly on the counter to release any large air bubbles and level the surface with a spatula.
Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. The tops should spring back when gently pressed and the edges will start to pull away from the pan. The aroma will be wonderfully chocolatey and slightly toasted.
Let the cakes cool in the pans for 10 minutes, then remove them from the pans to cool completely on a wire rack. Run a knife around the edges if needed and invert gently. Cooling on a rack prevents a soggy bottom.
For the buttercream, beat the softened butter until creamy. Gradually add the powdered sugar and continue to beat until smooth. Start slow so the powdered sugar does not puff everywhere. The mixture should look pale and fluffy.
Mix in the strawberry puree and vanilla extract until well combined. The buttercream will change to a delicate pink and smell bright and fruity. Taste and add a touch more puree if you prefer a stronger strawberry note, but be careful not to thin the frosting.
Once the cakes are cool, spread the strawberry buttercream between the layers and on top of the cake. Decorate as desired. Use an offset spatula for clean edges and finish with fresh strawberry slices or chocolate shavings for extra charm.

Fun Variations You Can Try
- Use roasted strawberries for a deeper, caramelized buttercream flavor. Roast whole berries at 400°F for 15 minutes with a sprinkle of sugar, then puree.
- Swap half the whole milk for buttermilk to make the cake slightly tangier and even more tender.
- For a nutty twist, fold 1/2 cup finely chopped toasted hazelnuts into the frosting or press them around the cake’s edges.
- Make this gluten free by substituting a 1:1 gluten-free flour blend and reducing the boiling water slightly if the batter appears too thin.
- Add a pinch of cinnamon or espresso powder to the dry mix to boost the chocolate complexity without making the cake taste like coffee.
- For a lighter frosting, fold whipped mascarpone into half the buttercream for a softer finish that still holds its shape.
These ideas make the recipe flexible for seasonality and dietary needs while keeping the heart of the cake intact. Small changes can shift the cake from cozy to elegant depending on your occasion.
How I Love to Serve It
I serve this cake in ways that make the moment feel intentional. For a cozy family dessert after a Sunday dinner, a simple slice with a dollop of lightly whipped cream and a few fresh strawberries is perfect. For a birthday or celebration I add chocolate curls and scatter edible flowers for a classic yet pretty finish.
- Keep slices slightly warm by bringing them to room temperature if refrigerated. The buttercream softens and the chocolate aroma blooms again.
- Pair with a strong brewed coffee or a milky hot chocolate for a layered dessert experience.
- For brunch gatherings arrange small slices on a platter with fresh fruit, roasted nuts, and a pot of tea for a relaxed, buffet style serving.
I love setting the plate with a linen napkin and a small spoon of extra strawberry puree on the side. The textures should play off one another. The moist, slightly dense chocolate crumb with the airy, fruity buttercream is the kind of bite that makes people pause and smile. It’s also simple enough to slice and serve while guests chat and linger at the table.
Helpful Tips from My Kitchen
- Always measure flour by spooning into the measuring cup and leveling with a knife. Scooping directly can pack too much flour and make the cake dry.
- Bring eggs, milk, and butter to room temperature for better emulsification. It helps the batter and frosting come together without lumps.
- When adding boiling water, stir slowly and watch the batter thin. That glossy texture is what gives this cake such a moist crumb.
- If your buttercream gets too soft, chill it for 10-15 minutes, then rewhip lightly. If it is too stiff, add a teaspoon of milk at a time until you reach spreadable consistency.
- Use an offset spatula and a bench scraper for clean sides if you want a professional finish. Chill the cake briefly between crumb coat and final coat for neater results.
- If berries are watery, simmer down the puree to concentrate flavor and reduce excess moisture before adding to the buttercream.
- Freeze extra cake layers for up to one month wrapped tightly. Thaw in the refrigerator overnight and bring to room temperature before frosting.
These small routines save time and stress. Little steps like room temperature ingredients and a quick chilling cycle make a big difference in texture and appearance.
Important Cooking Reminders
- Preheat the oven fully to ensure even baking and accurate timing.
- Cool cakes on a wire rack to prevent condensation and soggy layers.
- Store frosted cake in the refrigerator if your kitchen is warm. Bring to room temperature before serving for best texture.
- Freeze unfrosted layers wrapped tightly for up to one month. Thaw overnight in the refrigerator.
- Avoid overmixing the batter once the wet and dry ingredients are combined to maintain a tender crumb.
- Use fresh strawberries for the puree when possible to avoid off flavors from old fruit.
- To reheat individual slices, warm gently in the microwave for 8 to 12 seconds. Do not overheat or the buttercream will separate.

Common Questions You Might Have
How can I make the buttercream less sweet?
The buttercream sweetness can be tamed by using slightly less powdered sugar and adding a touch more butter or a spoonful of cream cheese or mascarpone. Chill the frosting briefly and re-whip for a lighter texture. If you use extra puree, do it in small amounts so the frosting does not become too loose.
Can I use frozen strawberries for the puree?
Yes. Thaw frozen strawberries and drain any excess liquid. Pulse in a blender and strain if you want a very smooth puree. If the puree seems watery, simmer it in a saucepan briefly to concentrate flavor, then cool before adding to the buttercream.
What should I do if my cake sinks in the middle?
A cake can sink if it is underbaked, the oven temperature is too low, or too much leavening was used. Check doneness with a toothpick and let cakes bake until it comes out clean. Avoid opening the oven door frequently during baking. If it happens, level the top with a serrated knife and use the excess as cake crumbs for decoration or mix into frosting for a fun cake crumb top.
