Before we get into it, I’d like to issue my own disclaimer about the inauthenticity of this recipe as a “Black Forest” cake. Any purist would quickly point out that a true, German Schwarzwälder Kirschtorte would be more of a spongy chocolate cake, soaked with kirsch (a clear cherry liqueur) and decorated with whipped cream, sour cherries and shavings of chocolate. But when is the last time you remember me sticking to tradition?
My version of this cake is a departure in almost every category, save for the chocolate and cherry flavors. Cake baking is not in my wheelhouse, so I went for a recipe that I knew I could count on—a sourdough chocolate cake from King Arthur Baking that has served me well before—and I adjusted the fillings to match it. My whipped cream filling is enhanced with mascarpone, making it more substantial to support the sturdy cake. The cake itself is not super sweet, so the cherries had to be. And kirsch liqueur (or any cherry liqueur, for that matter) is nowhere to be found in our liquor stores, so I reached straight for what’s plentiful at our house—bourbon, and that was a very good call.
The cake is not difficult to make, but it is fussy enough that it deserves a special occasion. I was going to save this until the week of Valentine’s Day, but my husband heard on his favorite sports talk show this morning that today is National Chocolate Cake Day, so, heck yeah! We might as well get a jump start on swooning over it. 😉
We splurged on this decadent, multi-layer dessert to finish our New Year’s Eve meal of White Clam Pizza and our newest addition, the Oysters Rockefeller Pizza, and the cake was delicious for the occasion (and, remarkably, just as good later as leftovers straight from the fridge).
Frosting a cake requires patience that I do not have (especially at the holidays), so I went for a more rustic appearance, which also afforded us a glimpse of the yumminess that was to come, in the form of mascarpone cream and cherries hanging out the sides. There was no whipped cream wrapped around the outside of my cake and no shavings of chocolate, as one would find on a true Black Forest Cake. But it was delicious, with a capital D.
So, is it authentic Black Forest Cake? No, but “Sourdough Dark Chocolate Cake with Bourbon-Soaked Cherry and Mascarpone Filling with Ganache Topping” is a mouthful. Plus, it didn’t fit in the title box. 😉
1 recipe Sourdough Chocolate Cake | King Arthur Baking, baked in 9-inch layer pans* (see instruction notes)
Bourbon Cherries and Syrup
1 lb. bag frozen dark sweet cherries
1/2 cup organic cane sugar
1/4 cup unsweetened black cherry juice
2 oz. bourbon
1 cup heavy cream
8 oz. tub mascarpone
1/4 cup powdered sugar, sifted
1 tsp. real vanilla extract
8 oz. dark melting chocolate wafers
1 cup heavy cream
1 oz. amaretto (optional)
8 bourbon cherries or morello cherries, with stems (for decorating cake top)
Bake the cake as instructed on King Arthur website. I followed the instructions with one ingredient adjustment; I replaced half of the natural cocoa with KA’s Double Dark Dutch Cocoa. I am crazy about the deep, dark color and chocolate flavor! Also, I baked it in two buttered and cocoa-dusted 9-inch layer pans rather than the 9 x 13 that was suggested, and the cake was done in 30 minutes. Cool the cake layers completely before removing them from the pans.
Not riding the sourdough train? No problem; use any other dark chocolate cake recipe you like, provided the layers are sturdy.
