Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. Grease and flour two 9-inch round cake pans. In a large bowl, sift together 1 3/4 cups all-purpose flour, 3/4 cup unsweetened cocoa powder, 1 1/2 tsp baking soda, 1 1/2 tsp baking powder, and 1 tsp salt.
  2. Step 2: In another large bowl, whisk 2 cups granulated sugar, 2 large eggs, 1 cup buttermilk, 1 cup warm water, 1/2 cup vegetable oil, and 2 tsp vanilla extract until smooth.
  3. Step 3: Gradually add dry ingredients to wet ingredients, mixing until just combined. Stir in 1 cup semi-sweet chocolate chips.
  4. Step 4: Divide batter evenly between prepared pans and bake for 30-35 minutes until a toothpick inserted comes out clean. Cool cakes in pans 10 minutes, then transfer to wire racks to cool completely.
  5. Step 5: For ganache, heat 1 cup heavy cream in a small saucepan until it just begins to simmer. Pour hot cream over 8 oz chopped semi-sweet chocolate in a bowl. Let sit 2 minutes, then stir until smooth and glossy.
  6. Step 6: Place one cake layer on a serving plate, pour and spread a thin layer of ganache over top. Place second layer on top and pour remaining ganache over entire cake, using a spatula to smooth sides. Allow ganache to set at room temperature before slicing.
