Ingredients

FOR DARK CHOCOLATE CAKE

  • 2 cups (240 g) all-purpose flour
  • 1 3/4 cups (350 g)granulated sugar
  • 3/4 cup (88.5 g) Cacao Barry Extra Brute Cocoa Powder or similar premium brand
  • 2 teaspoons (8 g) baking soda
  • 3/4 teaspoon (3 g) baking powder
  • 1 teaspoon (6 g) salt
  • 3 eggs, room temperature
  • 1 cup (240 g) buttermilk, room temperature
  • 1 cup (236.6 g) hot water or coffee
  • 1/2 cup (109 g) vegetable oil
  • 1 teaspoon (4.2 g) pure vanilla extract

FOR THE BUTTERCREAM

  • 2 cups (452 g) unsalted butter, chilled (I take the butter out of the fridge 30 minutes before I make my frosting)
  • 6 cups (750 g) powdered sugar, measured and then sifted
  • 1/4 cup (57.75 g) heavy whipping cream
  • 2 teaspoons (8.4 g) pure vanilla extract
  • Pinch of salt
  • *This buttercream recipe makes enough to fill and cover your cake. If you want to add additional piping, you’ll want to make an extra 1/2 batch.

Instructions

FOR THE CHOCOLATE CAKE

  • Preheat the oven to 325 degrees F. Prepare three 8-inch or four 6-inch round cake pans by spraying the bottom and sides with nonstick spray, lining the bottom with parchment paper, and spraying the parchment paper.
  • In a bowl of electric mixer, combine all the dry ingredients.
  • Combine eggs, buttermilk, water, oil and vanilla in a measuring cup and lightly beat with a fork.
  • Add wet ingredients to the dry ingredients, and mix on low speed until combined. Batter will be thin. Scrape sides and mix for another 30 seconds. Divide batter evenly among prepared pans (I like to use a kitchen scale to ensure the batter is evenly distributed - about 15 to 16 ounces in each 8-inch or 12 ounces in each 6-inch).
  • Bake for 23 top 27 minutes (you may need more time depending on your oven), until toothpick comes out with just a few moist crumbs on it. Cool on wire racks for 10-15 minutes, then gently invert onto racks until cooled completely.
  • When cakes are completely cooled, I like to wrap each cake layer individually with plastic wrap and stick it in the refrigerator or freezer until I’m ready to frost. The cake will be easier to work with if it’s cooled a bit. If I’m making the cake a day or two before I actually need to frost it, I put it in the freezer to ensure freshness. If I’m frosting same-day, I’ll just put it in the refrigerator to chill until needed.

FOR THE BUTTERCREAM:

  • In the bowl of a stand mixer fitted with a paddle attachment, cream the butter for about 2 minutes. This will soften the butter without it having to be warm.
  • With the mixer on low speed, gradually add the sifted powdered sugar, one cup at a time, mixing a little in between each addition.
  • With mixer on medium speed, add whipping cream, vanilla and salt.
  • Turn the mixer to medium-high speed and beat for an additional 5 to 7 minutes. The frosting will become lighter in color and texture.
  • Before spreading on your cake, spend a couple minutes mixing the buttercream by hand with a wooden spoon to push out the air pockets.

ASSEMBLY

  • Place the first cake layer, top side up and spread about 3/4 cup of frosting on top. Make sure to get eye level with the cake to ensure the frosting is spread evenly over the cake.
  • Repeat this step until you get to the final cake layer, which you will lay top side down.
  • Apply a thin coat of frosting around the entire cake to lock in the crumbs. Freeze for about 10 minutes.
  • After the crumb coat is set, continue frosting and decorating the cake.
