How to Make Buttermilk Brownies With Frosting

  1. Preheat oven to 350°F (175°C). Grease and flour a 15x10x1 inch baking pan.
  2. In a large mixing bowl, whisk together 2 cups all-purpose flour, 2 cups granulated sugar, 1 teaspoon baking soda, and 1/2 teaspoon salt. Set aside.
  3. In a medium saucepan over medium heat, combine 1 cup (2 sticks) unsalted butter, 1 cup water, and 1/3 cup unsweetened cocoa powder.
  4. Bring the mixture to a rolling boil, stirring constantly. Remove from heat.
  5. Pour the hot chocolate mixture into the dry ingredients and beat with an electric mixer until just combined.
  6. Add 2 large eggs, 1/2 cup buttermilk, and 1 1/2 teaspoons vanilla extract. Beat for 1 minute on medium speed.
  7. Pour the batter into the prepared baking 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:
  10. In a small saucepan over medium heat, combine 1/4 cup (1/2 stick) unsalted butter, 3 tablespoons unsweetened cocoa powder, and 3 tablespoons buttermilk.
  11. Bring to a simmer, stirring constantly. Remove from heat.
  12. Add 2 cups powdered sugar and 1/2 teaspoon vanilla extract. Beat until smooth and creamy.
  13. Once the brownies are slightly cooled, pour the warm frosting over the top and spread evenly.
  14. Let the brownies cool completely in the pan before cutting into bars.
