Instructions

  1. Combine the butter and cocoa powder in a bowl over a pot of boiling water (double boiler). Cook until the butter melts.
  2. Add the chocolate to the butter mixture and cook, stirring occasionally, until the chocolate has completely melted (about 10 minutes).
  3. While the chocolate melts, line a 9″ x 13″ casserole dish with parchment paper leaving enough for a couple inches to hang over each side.
  4. In the bowl of a stand mixer, combine the eggs, sugars and vanilla.
  5. Whisk on low until combined (about 1-2 minutes). Scrape down the sides.
  6. With the stand mixer on medium, pour the chocolate mixture down the side of the bowl. Add the whiskey and whisk until smooth (about 1 minute).
  7. Fold in the flour and salt until just combined.
  8. Pour the batter into the prepared casserole dish and bake at 350F for 35-40 minutes.
  9. In a saucepan over medium heat, combine the peanut butter and butter for the frosting. Cook, stirring occasionally, until melt.
  10. Transfer to a bowl and stir in the whiskey and vanilla extract. Add the powdered sugar and beat with a handheld mixer (or stand mixer) until smooth.
  11. Spread the frosting over the top of the cooled brownies.
  12. In a bowl over a pot of boiling water, combine the chocolate and heavy cream for the ganache.
  13. Cook until the ganache can be stirred smooth (about 5 minutes).
  14. Spread the ganache over the frosting. Allow to cool until set (about 1 hour in the refrigerator).
