Ingredients
  

For the cake:
  • 3 cups all-purpose flour, sifted 360g
  • 2 2/3 cups granulated cane sugar 530g
  • 1/2 cup plain sour cream 115g
  • 1/2 cup unsweetened cocoa powder, Dutch-processed 50g
  • 3/4 teaspoon fine kosher salt 4g
  • 1 1/2 teaspoons baking powder 6g
  • 1 tablespoon baking soda 18g
  • 3 large free-range eggs
  • 1 cup cultured buttermilk 236mL
  • 1 1/2 cups freshly brewed strong coffee, hot 354mL
  • 3/4 cup light vegetable oil 177mL
  • 1 tablespoon pure vanilla extract 15mL
  • 1 teaspoon espresso powder optional, enhances chocolate depth
For the frosting:
  • 1 1/2 cups unsalted European-style butter, softened 330g
  • 1 pound powdered sugar, sifted 453g
  • 1/3 cup chocolate fudge or ganache 100g
  • 1/2 cup Dutch-processed cocoa powder 50g
  • 1 teaspoon coffee liqueur or brewed espresso optional, adds richness
  • 3/4 teaspoon fine sea salt 4g

Method
 

Step 1: Preheat the Oven
  1. Preheat your oven to 350°F (177°C). Grease and flour the baking sheet or line it with parchment paper for easy removal.
Step 2: Combine the Dry Ingredients
  1. In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. This will aerate the flour, making your cake lighter.
Step 3: Blend the Wet Ingredients
  1. In another bowl, combine the sour cream, buttermilk, vegetable oil, eggs, hot coffee, vanilla extract, and espresso powder, if using. Whisk until smooth. The warmth from the coffee should point you toward a comforting aroma.
Step 4: Mix Wet and Dry
  1. Pour the wet mixture into the dry ingredients. Use a spatula or a hand mixer on low speed to combine until just blended. Be cautious not to overmix; a few lumps are just perfect.
Step 5: Pour and Bake
  1. Pour the batter into the prepared baking sheet. Smooth the top using a spatula. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Step 6: Cool the Cake
  1. Let the cake cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.
Step 7: Prepare the Frosting
  1. In a bowl, beat the butter until light and fluffy. Gradually add in the powdered sugar, cocoa powder, and salt. Pour in the chocolate fudge or ganache and mix until combined. Add coffee liqueur or brewed espresso if you want that added depth.
Step 8: Frost the Cake
  1. Once the cake is completely cool, spread the frosting generously on top. You can decorate with chocolate shavings, sprinkles, or fresh berries if you’re feeling fancy.

Notes

  • Sifting Flour: Always sift your flour and cocoa powder for a lighter cake.
  • Buttermilk Substitute: If you don’t have buttermilk on hand, mix 1 cup of milk with a tablespoon of vinegar or lemon juice and let it sit for 5 minutes.
  • Oven Thermometer: If you suspect your oven isn’t accurate, an oven thermometer can help ensure you bake at the right temperature.
  • Cool Completely: Always cool the cake completely before frosting. This prevents the frosting from melting.
  • Storage Tips: This cake can be covered with a cake dome or plastic wrap and stored at room temperature for up to three days.
