Ingredients:
- 250g all-purpose flour
- 400g granulated sugar
- 75g unsweetened Dutch-process cocoa powder
- 2 tsp baking soda
- 1 tsp baking powder
- 1 tsp sea salt
- 240ml buttermilk, room temperature
- 120ml vegetable oil
- 2 large eggs, room temperature
- 2 tsp pure vanilla extract
- 240ml boiling water
- 700g jarred pitted sour cherries (Morello cherries), with juice
- 50g granulated sugar
- 15g cornstarch
- 60ml Kirsch (Cherry Brandy)
- 720ml heavy whipping cream, cold
- 60g powdered sugar
- 100g cold mascarpone
- 1 tsp vanilla extract
- 100g dark chocolate shavings
Instructions:
- Preheat oven to 350°F (175°C) and grease three 8-inch round cake pans, lining the bottoms with parchment paper.
- Sift flour, sugar, cocoa, baking soda, baking powder, and salt into a large mixing bowl.
- In a separate container, whisk buttermilk, vegetable oil, eggs, and vanilla extract until well combined.
- Slowly incorporate the wet ingredients into the dry ingredients. Carefully stir in the boiling water until the batter is smooth (it will be thin).
- Divide the batter evenly among the three prepared pans. Bake for 30 minutes, or until a toothpick inserted into the center comes out clean. Cool completely on wire racks.
- While the cake cools, prepare the cherry filling by simmering cherries, their juice, sugar, and cornstarch in a saucepan over medium heat until thickened. Stir in the Kirsch and let cool.
- Prepare the frosting by whipping cold heavy cream, powdered sugar, mascarpone, and vanilla extract until stiff peaks form.
- Assemble the cake by layering sponge, cherry filling, and whipped cream. Cover the exterior with remaining cream, chocolate shavings, and reserved whole cherries.
- Chill the assembled cake in the refrigerator for at least 2 hours before slicing to allow the layers to stabilize.
