Ganache:
Chocolate whipped cream frosting (or substitute a favorite frosting):
Whisk together flour, sugar, cocoa, baking powder, baking soda, salt, and espresso powder in large bowl.
With beater going on medium, mix in milk, oil, egg, and vanilla.
With beater on low, mix in boiling water.
Pour into greased and floured cake pans (I use medium ramekins).
Bake ate 350F° for 30–40 minutes.
For the ganache: Bring cream to a simmer, add chocolate, ancho, and cinnamon and remove from heat. Allow to sit 5–10 minutes, then stir until chocolate is fully dissolved. Sit until it comes to room temperature.
Level the layers and spread ganache between layers.
For frosting, whip cream until it begins to stiffen, then add sugar and cocoa and whip just until incorporated.
