My classic go-to recipe. The key to brownies is always to underbake them.
Author: Leona Konkel
Grease 9x13 inch baking pan. Microwave butter until melted. Stir in sugar and vanilla. Add eggs, beating well after each addition. Add flour, cocoa, baking powder, and salt. Beat until well-blended. Pour into prepared pan. Bake at 350F for 30-35 minutes, or until brownies begin to pull away from sides of pan. Good brownies are best if they're underdone; a toothpick inserted into the center should have moist crumbs clinging to it.
