Layer Brownies and Buttercream
  1. Take cool brownies and frost top with buttercream.
  2. Chill completely before adding ganache.
  1. Warm heavy cream in saucepan over medium heat until just starting to lightly bubble.
  2. Remove from heat and pour warm cream over chopped chocolate.
  3. Allow to sit for 2-3 minutes to soften.
  4. Lightly fold, taking care to not stir too quickly to prevent air from incorporating.
  5. When ganache is very smooth, pour over chilled buttercream and return to refrigerator to set for at least an hour.
