Instructions
For the Cake:
Preheat oven to 350 F. Grease 2 8-inch cake pans and line the bottoms with parchment paper.
Cream butter and brown sugar in the bowl of a stand mixer with a paddle attachment on medium speed until light and fluffy.
Add eggs, one at a time, beating well after each addition.Beat in vanilla and coffee.
Whisk together flour, cocoa, baking soda and salt in a medium bowl.
Add the flour mixture to the wet ingredients in thirds, alternating with sour cream, and beating on low speed after each addition.
Stir in water and coffee until blended.
Pour cake batter into prepared pans. Bake 30-35 minutes in the center of oven, or until a toothpick inserted in the center comes out clean.
Let the cake cool in pans 10 minutes before removing to a wire rack.
Freeze the cake for at least 1 hour, and then level the top of the cake and cut each of the cake layers in half. The cake can be quite crumbly and is much easier to work with when frozen.
For the Kirschwasser Syrup
Place the sugar and water into a small saucepan. Stir and bring to a boil. Simmer until all of the sugar is melted. Let cool for 1-2 minutes, then stir in the cherry liqueur and let fully cool. This can be made up to one week ahead.
For the Whipped Cream Frosting:
Whip heavy cream and powdered sugar until in a stand mixer using the whisk attachment until stiff peaks form.
For the Chocolate Shavings:
Bring chocolate to room temperature. Shave small pieces off the bar using a vegetable peeler. Freeze until you are ready to use as they melt easily!
Cut each cake in half horizontally. Place the bottom cake layer on the cake decorating stand or serving plate. Brush generously with the Kirchwasser syrup. Top the first cake layer with approximately 1 cup of whipped cream by piping out a spiral on top of the cake, starting at the middle. Top with 1/3 cup of cherries and gently press them into the whipped cream.
Repeat with the second cake layer, followed by the third cake layer. Brush the fourth cake layer with syrup and place it, syrup side down, on top of the cake.
Pipe a spiral of whipped cream on the top of the cake and pipe whipped cream along the side of the cake. Smooth the whipped cream with an offset spatula or cake comb.
Use a bench scraper to toss the chocolate shavings onto the sides of the cake as they melt with frustrating ease on your warm hands!
Pipe 8 whipped cream rosettes onto the top of the cake with the remaining whipped cream and top each with a maraschino cherry.
