How to Make Buttermilk Chocolate Brownies

  1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. In a large bowl, whisk together 1 ½ cups all-purpose flour, 1 ½ cups granulated sugar, ¾ teaspoon baking soda, and ½ teaspoon salt. Set aside.
  3. In a medium saucepan, combine ½ cup (1 stick) unsalted butter, ¾ cup unsweetened cocoa powder, and 1 cup water.
  4. Bring the mixture to a gentle boil, stirring constantly until the butter and cocoa are melted and smooth.
  5. Remove from heat and pour the chocolate mixture into the dry ingredients. Beat with an electric mixer until just combined.
  6. Add 2 large eggs, 1 cup buttermilk, and 1 teaspoon vanilla extract. Beat for 1 minute, until the batter is smooth but still slightly thick.
  7. Pour the batter into the prepared pan and spread evenly.
  8. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  9. While the brownies are baking, prepare the frosting: In a small saucepan, combine ¼ cup (½ stick) unsalted butter, ¼ cup unsweetened cocoa powder, and ¼ cup buttermilk.
  10. Bring to a simmer over medium heat, stirring constantly until smooth. Remove from heat and stir in 2 cups powdered sugar and 1 teaspoon vanilla extract until smooth and creamy.
  11. Stir in ½ cup chopped pecans (optional).
  12. Pour the warm frosting over the warm brownies and spread evenly.
  13. Let the brownies cool completely before cutting and serving.
