  • 1 ½ cups cola soft drink such as Coca Cola or Dr. Pepper
  • 1 cup vegetable or canola oil
  • ½ cup unsweetened cocoa
  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1 cup firmly packed light brown sugar
  • 1 ½ teaspoon baking soda
  • ½ teaspoon table salt
  • ½ cup buttermilk
  • 2 large eggs lightly beaten

  • ½ 4-oz. unsweetened chocolate baking bar, chopped
  • 3 tablespoons milk
  • 3 tablespoons cola soft drink
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract


  • 1 ¼ cups toasted pecans chopped


  • Preheat the oven to 350 degrees Fahrenheit. Lightly grease a 17 1/2 by 12 1/2 inch jelly-roll pan.
  • In a medium sauce pan over medium-high heat, bring the cola, oil and unsweetened cocoa to a boil, stirring often. Remove from the heat.

  • Bake at 350°F for 18 to 22 minutes or until a wooden pick inserted in center comes out clean.

Make the Frosting

  • In a medium saucepan over medium-low heat, heat the butter and chocolate stirring constantly until melted and smooth. Remove from heat and whisk in the milk and the soft drink until blended. Stir in the sugar and vanilla. Beat at medium speed with an electric mixer until smooth.
  • Pour the frosting over the warm cake, spreading gently to the edges. Sprinkle with chopped pecans. Cool completely before serving.
