    Cup of Yum

  2. For the brownies: In a large glass bowl, combine the unsweetened chocolate and butter. Heat in microwave 1-2 minutes stirring intermittently until melted and smooth.
  3. Beat in eggs, sugar, vanilla, and salt until well blended.
  4. Stir in flour, blending well.
  5. Spread evenly into prepared pan. Bake 25-30 minutes. Do not overbake! Brownies should be moist. Cool in pan.

Notes

  • Tips: Line the pan with heavy duty foil and then spray it. After brownies are done lift the whole pan of brownies out by the foil for easier cutting.Source: my neighbor Julie Motes
