Ingredients:

  • 2 cups All-Purpose Flour, sifted
  • 2 cups Granulated Sugar
  • 1 teaspoon Baking Soda
  • ½ teaspoon Salt
  • 1 cup (2 sticks) Unsalted Butter, cut into pieces
  • 1 cup Coca-Cola (Classic)
  • ½ cup Unsweetened Cocoa Powder
  • ½ cup Buttermilk
  • 2 Large Eggs, lightly beaten
  • 1 teaspoon Vanilla Extract
  • ½ cup Unsalted Butter (for glaze)
  • 6 tablespoons Coca-Cola (for glaze)
  • 3 tablespoons Unsweetened Cocoa Powder (for glaze)
  • 3 cups Powdered Sugar (Icing Sugar), sifted
  • ½ cup Chopped Pecans or Walnuts (Optional)

Instructions:

  1. Preheat oven to 350°F (175°C). Grease and lightly flour a 9x13 inch baking pan.
  2. In a large bowl, whisk together the flour, sugar, baking soda, and salt. Set aside.
  3. In a large saucepan, combine the 1 cup of butter, 1 cup of Coca-Cola, and ½ cup of cocoa powder. Heat over medium heat, stirring occasionally, until the mixture comes to a gentle boil. Remove immediately from heat.
  4. Pour the hot cola mixture over the dry ingredients in the large bowl. Mix gently until just combined.
  5. In a separate small bowl, whisk together the buttermilk, lightly beaten eggs, and vanilla extract.
  6. Gradually whisk the buttermilk mixture into the chocolate mixture until smooth. Do not overmix. Pour batter into the prepared pan.
  7. Bake for 30–35 minutes, or until a wooden skewer inserted near the centre comes out clean.
  8. While the cake bakes, prepare the glaze: In a clean saucepan, melt the ½ cup of butter for the glaze. Stir in the 6 tablespoons of Coca-Cola and 3 tablespoons of cocoa powder. Bring this mixture to a rolling boil, then immediately remove from heat.
  9. Stir the sifted powdered sugar into the hot glaze mixture until smooth and glossy. If using nuts, stir them in now.
  10. While the cake is still warm, pour the hot glaze evenly over the top and use a spatula to spread quickly before it sets. Allow the cake to cool completely in the pan on a wire rack before serving.
