Ingredients
Scale
- 2 cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup boiling water
- 1 pound fresh strawberries, hulled and sliced
- ½ cup granulated sugar
- 2 tablespoons lemon juice
- 1 tablespoon cornstarch
- ¼ cup water
- 12 ounces semi-sweet chocolate, finely chopped
- 1 cup heavy cream
- 2 tablespoons unsalted butter, softened
- 1 cup (2 sticks) unsalted butter, softened
- 3 cups powdered sugar
- ½ cup strawberry puree (from fresh strawberries)
- 1 teaspoon vanilla extract
- Pinch of salt
- 2–3 tablespoons milk or cream, if needed for consistency
- Fresh strawberries
- Chocolate shavings
Instructions
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Line the bottoms with parchment paper rounds.
- In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- In a separate bowl, whisk together buttermilk, vegetable oil, eggs, and vanilla extract.
- Gradually add wet ingredients to dry ingredients, mixing on low speed until just combined.
- Slowly pour in boiling water while mixing on low speed. The batter will be thin.
- Divide batter evenly between prepared cake pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
- Let cakes cool in pans for 10 minutes before inverting them onto a wire rack to cool completely.
- In a medium saucepan, combine sliced strawberries, sugar, and lemon juice.
- Cook over medium heat, stirring occasionally, until strawberries release their juices and soften, about 5-7 minutes.
- In a small bowl, whisk together cornstarch and water to create a slurry. Pour slurry into strawberry mixture and cook, stirring constantly, until filling thickens, about 1-2 minutes.
- Remove from heat and let strawberry filling cool completely before using.
- Place chopped chocolate in a heatproof bowl.
- In a saucepan, heat heavy cream over medium heat until it just begins to simmer. Do not boil.
- Pour hot cream over chopped chocolate. Let it sit for 1 minute.
- Gently stir the mixture until chocolate is completely melted and the ganache is smooth and glossy.
- Stir in softened butter until fully incorporated.
- Let ganache cool slightly before using. It should be thick enough to spread but still pourable.
- Wash and hull about 1 cup of fresh strawberries. Puree them in a blender or food processor until smooth. Strain the puree through a fine-mesh sieve to remove the seeds. You should have about ½ cup of strawberry puree.
- In a large bowl, beat softened butter with an electric mixer until light and fluffy, about 3-5 minutes.
- Gradually add powdered sugar, one cup at a time, beating on low speed until combined.
- Add strawberry puree, vanilla extract, and salt. Beat on medium speed until well combined.
- If frosting is too thick, add milk or cream, one tablespoon at a time, until you reach your desired consistency.
- If cake layers are uneven, use a serrated knife to level the tops.
- Place one cake layer on a serving plate or cake stand.
- Spread strawberry filling evenly over the first cake layer, leaving a small border around the edge.
- Carefully place the second cake layer on top of the strawberry filling.
- Apply a thin layer of strawberry buttercream frosting over the entire cake (crumb coat). Refrigerate the cake for 30 minutes to allow the crumb coat to set.
- Apply a generous layer of strawberry buttercream frosting over the entire cake, smoothing it out with a spatula or frosting smoother.
- Drizzle cooled chocolate ganache over the top of the cake, allowing it to drip down the sides.
- Decorate the cake with fresh strawberries and chocolate shavings, if desired.
- Refrigerate the cake for at least 30 minutes before serving.
Notes
- Use parchment paper rounds in the cake pans to ensure easy release.
- Don’t overmix the cake batter, as this can lead to a tough cake.
- The hot water in the cake batter helps to bloom the cocoa powder and creates a moist cake.
- Cool the strawberry filling completely before using to prevent it from melting the frosting.
- Strain the strawberry puree to remove the seeds for a smoother frosting.
- A crumb coat helps to seal in any loose crumbs and create a smooth surface for the final frosting layer.
- Refrigerate the cake before serving to allow the frosting and ganache to set.
