Instructions
-
Make the raspberry filling:
In a saucepan, combine water, cornstarch, raspberries, sugar, and lemon juice. Cook over medium heat, mashing and stirring until thick and bubbly (about 5 minutes). Remove from heat, stir in vanilla, and chill for at least 4 hours. -
Bake the cakes:
Preheat oven to 350°F (177°C). Grease and line three 9-inch cake pans with parchment. In a large bowl, whisk dry ingredients. In another, mix oil, eggs, sour cream, buttermilk, and vanilla. Combine wet and dry, add hot water/coffee, and fold in chocolate chips. Divide into pans and bake 24–26 mins. Cool completely. -
Make the buttercream:
Beat butter until creamy. Add sugar, cocoa, cream, salt, and vanilla. Beat until smooth and fluffy. -
Assemble the cake:
Layer cake, spreading a thin buttercream layer and piping a “dam” around the edges. Fill with chilled raspberry filling. Repeat for next layer. Add the final cake layer and apply a crumb coat. Chill for 30 minutes. -
Make the ganache:
Heat cream (and liqueur if using) until simmering. Pour over chopped chocolate and let sit 2 minutes. Stir until smooth. Chill 30 mins to thicken.
-
Finish and garnish:
Spread thickened ganache over the cake. Top with fresh raspberries and mint. Serve right away or chill until ready.
Notes
- Don’t skip the dam! It keeps the raspberry filling from sneaking out the sides.
- Make ahead: Raspberry filling can be made up to a week in advance. Cakes can be baked a day ahead and stored tightly wrapped.
- For extra decadence, use dark chocolate in the ganache.
- No buttermilk? Sub 1/2 cup milk + 1½ tsp vinegar or lemon juice.
