How to Make Old Fashioned Chocolate Brownie Cake

  1. Preheat oven to 375°F (190°C). Grease and flour a 9x13 inch baking pan.
  2. In a large microwave-safe bowl, combine 1 cup (2 sticks) unsalted butter, 1 cup vegetable shortening, 2 cups unsweetened cocoa powder, and 1 cup water.
  3. Heat in the microwave, stirring frequently, until mixture is boiling and smooth.
  4. In a separate large bowl, whisk together 2 cups granulated sugar and 2 cups all-purpose flour.
  5. Gradually pour the hot chocolate mixture into the sugar and flour mixture, mixing until just combined.
  6. Add 4 large eggs, 1 teaspoon vanilla extract, and 1 teaspoon baking powder to the batter. Beat until well blended. (Optional: Add 1 cup chocolate chips and/or 1 cup chopped nuts)
  7. Pour batter into the prepared pan and bake for 35-45 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  8. While the cake is baking, prepare the frosting.
  9. In a medium microwave-safe bowl, combine ½ cup (1 stick) unsalted butter, ½ cup unsweetened cocoa powder, and ½ cup buttermilk.
  10. Heat in the microwave, stirring occasionally, until boiling and smooth.
  11. Pour the hot mixture into a mixing bowl and add 3 cups powdered sugar and 1 teaspoon vanilla extract.
  12. Beat with an electric mixer until smooth and creamy.
  13. Immediately after removing the cake from the oven, pour the warm frosting evenly over the top.
  14. If using, sprinkle with additional chopped nuts while the frosting is still soft.
