Ingredients

The following ingredients have 12 Servings
  • 1 2/3 cups (200 grams) all-purpose flour 
  • 1 1/2 cups (297 grams) granulated sugar
  • 2/3 cup (57 grams) cocoa powder
  • 1 1/2 teaspoon baking soda
  • 1 teaspoon salt 
  • 1 1/2 cups (350 ml) buttermilk (at room temperature)
  • 1/2 cup (8 tablespoons, 113 grams) unsalted butter (at room temperature)
  • 2 eggs (at room temperature)
  • 1 teaspoon vanilla extract
  • 1/2 cup (8 tablespoons, 113 grams) unsalted butter
  • 2/3 cup (57 grams) cocoa powder
  • 3 cups (681 grams) powdered sugar
  • 1/3 cup (70 ml) milk ((whole or skim is fine))
  • 1 teaspoon vanilla extract

Instruction

  • Preheat oven to 350 degrees F (180 C). Lightly coat a large (9x13") baking pan with non-stick cooking spray, or grease lightly with butter. 
  • To make the cake, combine all ingredients in a large bowl, and using an electric or hand mixer, blend for about 30 seconds on low speed. Turn the speed up to medium-high and blend for an additional 2-3 minutes, stopping to scrape the bowl at least once with a spatula.
  • Pour batter into the prepared pan and bake for 25-30 minutes, until a toothpick inserted into the center comes out clean or with loose crumbs. Allow cake to cool to room temperature before frosting.
  • To prepare the frosting, melt the butter in a large bowl. Using an electric or hand mixer, stir in the cocoa powder. While beating the mixture on medium-high speed, alternately add powdered sugar and milk, until the frosting reaches a thick, spreadable consistency. Beat in vanilla extract. 
  • Frost cake, decorate as desired, and serve.
