Instructions
Make the Chocolate Cake
Preheat the oven to 350ºF and prepare three 6-inch or two 8-inch cake pans by spraying the sides with cooking spray and fitting the bottoms with a wax paper or parchment cake circle.
Place all of the dry ingredients into the bowl of a stand mixer and stir on low for 30 seconds to fully combine them. Add the vegetable oil, eggs, vanilla, and buttermilk and mix on low until just combined. With the mixer still on low, add the hot water in a slow stream, then turn the mixer to medium and beat until smooth, about 2 minutes. The batter will be very thin.
Pour into prepared cake pans no more than 2/3 full and bake for 30-35 minutes, until a wooden toothpick inserted comes out clean. Cool completely before filling and frosting.
Make the Raspberry Buttercream
With a food processor, grind the raspberries into a fine powder. Sift out the seeds (if a few seeds end up in the powder that is totally ok) and set the powder aside.
Whip the butter using a stand mixer with a paddle attachment on medium speed until it’s creamy and light in color (5-10 minutes). Add vanilla, milk, and raspberry powder and continue to mix on medium for about two minutes.
Add powdered sugar a few cups at a time, scraping down the bowl and paddle after each addition. Add the salt and mix on low for another 30 seconds.
Make the Chocolate Ganache
Place chocolate chips into a heat resistant bowl (glass or metal). If you’re starting with a chocolate bar, chop it into small pieces until they’re about the size of chocolate chips.
In a saucepan over medium-high heat, warm heavy whipping cream until it just starts to simmer. I always look for small bubbles forming around the edge and a soft simmer starting in the middle. When it's reached this point, pour the cream into your bowl of chocolate and let sit for about 30 seconds.
Whisk it together until it’s uniform in consistency and there are no bits of chocolate left on your whisk. Cool ganache at room temperature for 10-20 minutes, or until the ganache itself is room temperature or slightly above.
Assembly
Once the Chocolate Cakes are cooled completely, level and torte the layers to make them even before filling and frosting with the Raspberry Buttercream. After the final layer of frosting is applied, chill the cake for 20-30 minutes before dripping with the Chocolate Ganache. To recreate the look pictured, add swirls of Raspberry Buttercream around the top of the cake with Wilton Tip 4B and add a fresh raspberry to the top of each swirl.
Notes
*DIY Buttermilk recipe: add 1 Tbsp of white vinegar to a jar and top it with 1 Cup of whole milk. Stir and let sit for 15 minutes before using in the recipe. **Raspberries: if you can't find freeze-dried raspberries, I do have this raspberry buttercream recipe that uses fresh berries. Make Ahead Tips:
The Chocolate Cake can be made ahead and stored at room temperature, covered tightly in plastic wrap, for up to two days. Alternatively, you can cover with plastic wrap and store in the freezer for up to two months before thawing to room temperature.
The Raspberry Buttercream can be made ahead and stored in an airtight container in the refrigerator for up to two weeks. When you're ready to use it, bring it back to room temperature and mix it together on low for about 30 seconds to bring it back to frosting consistency.
The Chocolate Ganache can be made ahead and stored in the refrigerator in an airtight container for up to two weeks. When you’re ready to use it as a drip, microwave it in 10 second increments, stirring after every interval until your ganache is room temperature and uniform in consistency.
To Make as Cupcakes: fill cupcake tins no more than 2/3 full and bake at 350ºF for 15-17 minutes, until a toothpick inserted comes out clean.
