Ingredients

Chocolate Cake:

  • 360 g black coffee or 2 teaspoons instant coffee for an easy substitute
  • 360 g all-purpose flour measured accurately for the best texture
  • 2 tablespoons cornstarch to improve cake tenderness
  • 300 g granulated sugar for sweetness and moisture
  • 150 g dark brown sugar adds depth to the flavor
  • 75 g unsweetened Dutch cocoa powder use high-quality cocoa for the best taste
  • 1 ½ teaspoons baking powder leavening agent
  • 1 ½ teaspoons baking soda helps the cake rise
  • 1 ½ teaspoons salt enhances all the flavors
  • 165 g vegetable oil for moisture and tenderness
  • 270 g sour cream 14-18% fat room temperature
  • 3 large eggs room temperature for best results
  • 3 teaspoons vanilla extract adds a touch of warmth

Coffee Buttercream:

  • 400 g butter softened to room temperature
  • 660 g powdered sugar sifted to prevent lumps
  • 2 teaspoons vanilla extract for a sweet aromatic flavor
  • 2-2 ½ tablespoons black coffee cooled to room temperature
  • 1 tablespoon instant espresso powder optional intensifies the coffee flavor

Instructions

  • Preheat the oven to 170ºC/340ºF (conventional).
  • Prepare three 20 cm (8-inch) round cake pans by lining them with parchment paper.
  • Brew the coffee and set it aside to cool while you prepare the other ingredients.
  • In a large bowl, sift together all the dry ingredients. Stir them gently to ensure they are evenly combined.
  • In another mixing bowl, combine all the wet ingredients, including the coffee. Whisk together gently until the mixture is smooth.
  • Slowly add the wet ingredients into the dry ingredients. Stir gently to combine until there are no lumps.
  • Evenly divide the cake batter between the prepared pans. Bake for 28-30 minutes, or until a cake tester comes out clean.
  • Let the cakes cool in the pans for 5 minutes, then transfer them to a cooling rack to cool completely.
  • For the coffee buttercream: In a small cup or bowl, combine the coffee and instant espresso powder (if using). Stir until dissolved and set aside.
  • In a stand mixer with the paddle attachment (or using a hand mixer), beat the softened butter for 4 minutes on medium-high speed. Scrape down the sides of the bowl, then beat for another 2 minutes.
  • Gradually add the sifted powdered sugar, vanilla extract, and cooled coffee in two parts, mixing well after each addition. Optionally, add vanilla paste for an enhanced vanilla flavor.
  • Scrape down the bowl and mix again for 2 more minutes until the buttercream is smooth and fluffy.
  • Assembling the cake: Once the cakes are completely cool, trim the tops of each cake layer to make them flat.
  • Place the first cake layer on a turntable or serving plate. Spread a generous amount of frosting on top, then add the second cake layer. Repeat the frosting and layering process.
  • Top with the final cake layer and cover the entire cake with a thin crumb coat. Apply the remaining buttercream to cover the cake completely.
