• Preheat the oven to 350F or 180C. Have two 8-inch x 2-inch round cake pans ready. Line the bottom of the pans with parchment paper, then butter and flour the pans.

Prepare Cake

• Combine the dry ingredients - Powder the granulated sugar so that it's easy to mix. Sift together flour, sugar, cocoa, baking soda, baking powder, and salt into the bowl of a stand mixer. Alternately, you can use an electric mixer.
  
• In another bowl, combine the buttermilk, oil, eggs, and vanilla. Refer the notes for the measurement of eggs.
  
• With the mixer on low speed, slowly add the wet ingredients to the dry. With the mixer still on low, add the coffee and stir just to combine, scraping the bottom of the bowl with a rubber spatula.
  
• 
• Pour the batter into the prepared pans and bake for 35 to 40 minutes, until a cake tester comes out clean. Cool in the pans for 30 minutes, then turn them out onto a cooling rack and cool completely.

Prepare chocolate coffee ganache

• Melt chocolate in a small bowl in microwave or on the stovetop. In another saucepan, bring cream just to a boil. Pour over chocolate. Add coffee powder and whisk until smooth. Cool, occasionally stirring, until ganache reaches spreading consistency.

Assemble the cake

• Place one layer of cake, flat side up, on a flat plate or cake stand. With a knife or offset spatula, spread the top with filling. Place the second layer on the top, rounded side up, and spread the ganache evenly on the top and sides of the cake. You can also serve it with a scoop of ice cream! Enjoy :)
