October 27th was local design agency Northern Army‘s first birthday, and I was asked to make them a cake to commemorate the occasion, ideally incorporating their logo. I’d recently been toying with the idea of a spicy black forest cake, and this seemed like the ideal opportunity to finalize the recipe.
I made 3 square cake layers using the recipe below. The icing was a similar combination to the one I used for my Cupcake Camp Cupcakes – I find it eliminates the chalky mouthfeel I get from using a simple buttercream. I layered the cake with thick layers of frosting (next time, I’m making the icing batch bigger so I can get a better ratio of cake to icing). I printed out the Northern Army letters at about 320 pt Helvetica Bold, cut them out, and laid them on rolled-out white fondant. I cut the letters out of the white, then rolled out a full tub of Duff’s Black Fondant that I got at Michaels. I covered the cake, then cut the letters out of the black. I laid the white letters where the black cutouts were to make a relatively flush surface. To make it shiny, I brushed the cake all over with kirsch.
Haunted Forest Cake with Cherry-Kirsch Frosting
3/4 cups cocoa, sifted
1 1/4 cups hot water
2/3 cup sour cream
3 cups pastry flour or type 00 flour
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
1 tbsp instant espresso powder
1 1/2 teaspoons cinnamon
1 teaspoon cayenne pepper
1 1/4 cups butter, softened
1 1/2 cups granulated sugar
1 cup brown sugar
3 eggs, at room temperature
1 teaspoon vanilla bean paste
Preheat oven to 325º F. Grease 3 9-inch cake pans and line with parchment.
In a small bowl, whisk together the cocoa and instant espresso powder. Add the hot water and whisk until smooth. Add the sour cream and stir to combine.
In a medium bowl, sift together the flour, baking powder, baking soda, salt, cinnamon, and cayenne pepper. Whisk to ensure ingredients are combined.
In a large bowl, cream the softened butter. Add the granulated and brown sugar and mix until light and fluffy. Mix in the eggs, one at a time. Add the vanilla bean paste.
In 2 or 3 additions, add the flour mixture to the butter mixture alternately with the cocoa. Begin and end with the flour mixture, stirring until just combined.
Divide the batter evenly between the prepared pans. Bake at 325º F for 35 to 40 minutes or until a tester inserted in the centre of each cake comes out clean. Let cool in the pan on a rack for 10 minutes, then remove cake from pan to cool completely before frosting.
