Instructions
 

Chocolate Cake

  • Preheat oven to 325 degrees F.
  • Spray and line an 8-inch round cake pan with parchment paper.
  • In a large bowl, combine flour, sugar, cocoa, baking soda, baking powder, and salt.
  • In a separate bowl, whisk together buttermilk, oil, eggs, water, and vanilla.
  • Slowly add the wet ingredients to the dry ingredients, mixing until just combined.
  • Pour the batter into the prepared pan and bake for 28-30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs on it.
  • Let cool in the pan for 10-15 minutes, then invert onto a cooling rack to cool completely.

Chocolate Buttercream

  • In a large bowl, beat butter on medium-high speed for 2 minutes.
  • Slowly add ganache mixture and beat until smooth.
  • Gradually add powdered sugar and beat until combined.
  • Add vanilla and salt and beat on medium-high speed for 3-4 minutes, or until light and fluffy.

Raspberry Cake

  • Preheat oven to 325 degrees F.
  • Spray and line an 8-inch round cake pan with parchment paper.
  • In a medium bowl, whisk together flour, baking powder, salt, and freeze-dried raspberries.
  • In a large bowl, beat sugar and butter until light and fluffy.
  • Add egg and egg whites one at a time, beating well after each addition.
  • Add vanilla.
  • With the mixer on low, alternately add the flour mixture with the raspberry puree, starting and finishing with the flour mixture. Mix until just incorporated.
  • Fold in sour cream.
  • Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs on it.
  • Let cool completely and then divide the layers like you did with the chocolate cake.

Raspberry Cream Filling

  • In a food processor or blender, pulse the freeze-dried raspberries until they resemble a powder.
  • Add the sugar and cream. Scrape down the sides and corners to gather all the fruit powder.
  • Pulse the mixer for about 1-2 minutes or until the texture becomes thick like Greek yogurt.
  • Keep chilled until ready to use.

Ganache

  • Heat the cream in a microwave-safe bowl on medium-high heat for about 1 minute.
  • Pour the cream over the chocolate chips and stir until melted and smooth.
  • If the chips aren't melting all the way, microwave the mixture in 20-second intervals, stirring each time, until you've reached the desired consistency.

Assembly

  • Place the first half of the chocolate cake on a cake board.
  • Spread 1 cup of the raspberry cream over the cake layer.
  • Drizzle and spread chocolate ganache over the cream filling.
  • Place one of the raspberry cake layers on top of the ganache and spread with 1 cup of chocolate buttercream.
  • Repeat steps 1 and 3 and finish with the second raspberry cake layer on top.
  • Apply a thin layer of chocolate buttercream around the entire cake. This is your crumb coat. Freeze the cake for 10-15 minutes to set the crumb coat.
  • Once the cake has chilled, frost the cake with the remaining chocolate buttercream.
  • You can then use extra ganache, buttercream, and raspberry cream to decorate the top if desired.
  • Enjoy!
