Here’s how to make a classic cake with a dark chocolate twist, and easy buttercream frosting.

Chocolate cake is a classic for a reason. That’s why everyone should have at least one in their repertoire. Whether you’re throwing a birthday party or hosting a dinner, this recipe works for celebrations big and small. And adding dark chocolate to the equation makes it feel extra decadent.

Steps

  1. Preheat oven to 350°F (180°C). Butter three 9-inch cake pans and line with parchment paper.
  2. In a medium bowl, sift flour with cocoa powder, baking soda, baking powder and salt. In the bowl of a stand mixer fitted with the paddle attachment, beat sugars with butter on medium-high until light and fluffy, 1 minute. Reduce speed to medium-low and stream in melted chocolate until combined. Add eggs, one at a time, just until combined. Beat in vanilla. Add flour mixture into butter mixture in 3 parts, alternating with buttermilk in 2 parts. Divide batter between pans, smoothing tops.
  3. Bake in centre of oven until a tester inserted into the centre of cakes comes out clean, 35 to 40 minutes. Transfer to a rack. After 10 minutes, run a knife around sides of cakes. Turn out of pans. Invert and cool on racks, about 1 hour. Cover with plastic wrap and chill in refrigerator, 2 more hours.
  4. To assemble a layered cake, trim tops of cakes if needed. Place 1 cake round on a cake stand. Spread with ½ cup of the buttercream (see instructions, below). Lay another cake round on top. Repeat spreading and layering. Frost sides and top of cake.

Chocolate Buttercream Frosting

  1. In the bowl of a stand mixer fitted with the paddle attachment, beat butter with icing sugar on medium until combined, 1 minute. Reduce speed to medium-low and stream in melted chocolate until combined. Increase speed to medium-high and beat until very light and fluffy, 5 minutes.
  2. Beat in vanilla.
