  2. Melt together unsalted butter and semi-sweet chocolate in a medium saucepan over low heat, stirring until smooth.
  3. Whisk granulated sugar into the cooled chocolate mixture followed by eggs one at a time, then add vanilla extract.
  4. In a separate bowl, whisk the all-purpose flour, salt, and baking powder, then fold into the chocolate mixture until just combined.
  5. Pour brownie batter into the prepared pan and bake for 25-30 minutes, checking with a toothpick for doneness.
  6. Allow brownies to cool in the pan for 15-20 minutes before preparing the mint layer.
