  1. Preheat oven to 325°F (160°C).
  2. In a large bowl, cream together 1 cup (2 sticks) unsalted butter, 2 cups granulated sugar, and ¾ cup packed brown sugar until light and fluffy.
  3. Blend in ½ cup light corn syrup and a pinch of salt.
  4. Stir in 2 large eggs and 1 teaspoon vanilla extract.
  5. Gradually add 2 cups all-purpose flour and mix until just combined. Do not overmix.
  6. Pour batter into an ungreased 9x13 inch baking pan.
  7. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  8. While brownies are baking, prepare the frosting:
  9. In a medium bowl, combine 2 cups powdered sugar, 1 teaspoon vanilla extract, 1/3 cup (4 tablespoons) unsalted butter, 3 tablespoons unsweetened cocoa powder, and ⅓ cup creamy peanut butter.
  10. Gradually add milk, 1 tablespoon at a time, until you reach desired consistency.
  11. Once brownies have cooled slightly, frost with peanut butter frosting.
