Method
 

Step 1: Prep & Preheat
  1. Preheat oven to 350°F (175°C).
  2. Grease cake pans, line bottoms with parchment, and grease again.
Step 2: Mix Dry Ingredients
  1. In a large bowl, whisk together flour, cocoa powder, sugar, salt, baking powder, and baking soda.
Step 3: Mix Wet Ingredients
  1. In a separate bowl, beat eggs, milk, vegetable oil, and vanilla until well combined.
Step 4: Combine Wet & Dry
  1. Add wet ingredients to dry ingredients, mixing on low speed until just combined.
Step 5: Add Hot Liquids
  1. Slowly pour in hot coffee and hot water while mixing on low. Batter will be thin—this is normal!
Step 6: Bake the Cake
  1. Divide batter evenly among prepared pans.
  2. Bake 30–35 minutes, or until a toothpick inserted into the center comes out clean.
  3. Cool in pans 10 minutes, then transfer to wire racks to cool completely.
Step 7: Make the Chocolate Frosting
  1. Melt chopped semi-sweet chocolate in a double boiler or microwave until smooth; set aside to cool slightly.
  2. Beat softened butter on medium-high until creamy (~2 minutes).
  3. Add powdered sugar gradually, mixing on low.
  4. Pour in melted chocolate and vanilla; beat until combined.
  5. Slowly add heavy cream, beating on high until light and fluffy (~3 minutes).
Step 8: Assemble the Cake
  1. Place one cake layer on a serving plate; spread frosting evenly.
  2. Repeat with remaining layers.
  3. Frost the sides and top; smooth with an offset spatula.
  4. Garnish with chocolate shavings or sprinkles, if desired.
