For the Strawberry Buttercream:

  • 6 to 8 cups confectioners’ sugar (720g - 960g)
  • ½ cup chopped fresh strawberries (about 6 berries)

Instructions

For the Chocolate Cake:

  • Preheat the oven to 350F. Butter 3 (9-inch) round cake pans or spray with baking spray and line the bottoms with parchment paper. Wrap the outside with water-soaked fabric baking strips if you have them.
  • Into a medium bowl, sift the cocoa powder. Whisk in the hot water or coffee until the cocoa is dissolved. Let cool for 10 minutes.
  • Meanwhile, in a large bowl, whisk together the flour, sugar, baking soda, baking powder, and salt. To the cooled cocoa mixture, add the oil, buttermilk, eggs, and vanilla and whisk until well combined. Pour the cocoa mixture into the flour mixture and whisk until fully incorporated. Divide the batter among the cake pans.
  • Bake for 30 minutes or until the cakes are springy to the touch and just starting to pull away from the sides of the pan. (If you have to bake the cakes on separate oven racks, carefully rotate them after 20 minutes of baking.) Let cool completely in the pans. Run a knife around the edge of the cakes to loosen them and invert onto a wire rack. Remove and discard the parchment paper.

For the Strawberry Buttercream:

  • In a large mixing bowl or the bowl of a stand mixer fitted with the whisk attachment, beat the butter and a pinch of salt on medium speed until very light and fluffy, about 5 minutes.
  • Reduce the speed to low. With the mixer running, gradually add in the sugar, ½ a cup at a time, alternating with a tablespoon of the strawberries. Stop and scrape down the bowl a few times during mixing. Once the sugar is incorporated, beat on medium speed until light and fluffy, about 1 minute.
  • Place one cake layer on a serving plate. Top with ¾ cup of frosting and spread into an even layer. Top with another cake layer and another ¾ cup of frosting. Add the final layer and spread the remaining frosting all over the outside of the cake. Chill for at least 1 hour or up to 1 day.

For the Ganache:

  • Place the chopped chocolate in a medium heat-proof bowl.
  • In a small saucepan, heat the cream over medium-high heat just until simmering. Immediately pour over the chocolate and let stand for 5 minutes. Whisk together until the chocolate is fully melted and combined.
  • Spread over the top of the cake, letting some drip down the sides. Top with fresh berries. Chill and let the ganache set for at least 30 minutes before serving. Store the cake refrigerated for up to 5 days.

Notes

  • Make sure to sift the cocoa powder. Sifting ensures the cocoa powder is lump-free and is easy to combine with the hot water.
  • Substitute ¼ cup strawberry jam for the fresh strawberries in the frosting. This is a great option if your strawberries aren’t very sweet or flavorful. You could also spread a thin amount between each cake layer for added strawberry flavor.
  • Chill the frosted cake before adding the ganache drip. This helps the ganache set quickly and not drip all the way to the bottom of the cake.
