Tips for Perfect Mint Chocolate Brownies

  • Use pure peppermint extract, not mint flavoring.
  • Let each layer cool before adding the next.
  • Refrigerate before slicing for sharp, bakery-style cuts.
  • For extra richness, add ½ cup chocolate chips to the brownie batter.

Fun Variations

  • Add crushed chocolate sandwich cookies to the mint layer
  • Top with green sprinkles for extra festive flair (for Saint Patrick’s Day)
  • Swap ganache for melted dark chocolate for a thinner top

Storage

  • Store in refrigerator up to 5 days.
  • Freeze (layered and wrapped tightly) for up to 2 months.
