This is a recipe for Chile Chocolate Cake. A beautifully flavored chocolate cake topped with a rich decadent chocolate frosting spiked with bourbon.
Using a mixer with a wire whip attachment for best results, combine the flours, sugar, baking soda, salt, and cocoa and beat on low speed until well mixed. Add the softened butter to the dry mixture and beat thoroughly on medium-low speed. The mixture should be a uniform, grainy texture.
Raise the speed to medium and gradually add the remaining 1 cup of water and the buttermilk. Add the eggs, one at a time, beating well after each addition.
Combine the butter and cocoa in a large saucepan and melt over medium heat. Stir in the buttermilk. Add the confectioners’ sugar, a little at a time, stirring with a wire whisk between additions.
Stir in the bourbon and vanilla and continue to whisk until the frosting is smooth and glossy. The frosting should stiffen as it cools. (In warm weather you may need to refrigerate it.) When it is still warm, but has reached a spreadable consistency, you can assemble the cake.
If necessary, trim the tops of the cakes so that they are level. Place one of the cake layers on a 9-inch round cardboard cake circle. Spread 1 cup of the frosting over the layer. Sprinkle 1 cup of the chopped walnuts, if using, evenly over the frosting. Place the second layer of cake on the frosted base.
Use the remaining frosting to cover the top and sides of the cake. Finish the top of the cake by holding the spatula at a slight angle and making several strokes to smooth the top. To decorate the cake, press the remaining walnuts onto the lower half of the sides and on top of the cake.
This cake is best when made 1 to 2 days before serving as it gives the flavors time to blend.
