  • tsp baking powder
  • 1 tsp salt
  • 2 eggs

Instructions
 

Step 1: Make the Cake

  • Preheat oven to 350°F (175°C). Grease and line two 9-inch round cake pans.
  • In a large bowl, whisk flour, cocoa powder, sugar, baking soda, baking powder, and salt.
  • Add eggs, buttermilk, oil, and vanilla. Mix until smooth.
  • Dissolve espresso powder in boiling water and add to batter. Mix slowly until incorporated (it will be thin).
  • Divide batter evenly between pans.
  • Bake for 30–35 minutes or until a toothpick comes out with moist crumbs.
  • Cool in pans 10 minutes, then transfer to wire rack to cool completely.

Step 2: Prepare the Ganache

  • Heat cream in a saucepan until just simmering.
  • Pour over chopped chocolate in a bowl. Let sit 2 minutes, then stir until smooth.
  • Stir in butter and a pinch of salt. Let cool until thick enough to spread.

Step 3: Assemble the Cake

  • Place one cake layer on a serving plate. Spread ganache evenly over the top.
  • Add second cake layer and frost the top and sides generously with ganache.
  • Optional: Top with chocolate shavings, sprinkles, or drizzle with extra ganache.
