Notes

Ingredient Substitutions
  • Replace crème de menthe with peppermint extract (½ teaspoon) + 1 tablespoon milk for a kid-friendly option.
  • Use dark chocolate chips for a richer, less sweet glaze.
  • Add a drop of green food coloring to enhance the mint layer color if desired.
Make-Ahead & Storage
  • These brownies refrigerate beautifully for up to 5 days without drying out.
  • Store in an airtight container to maintain the soft mint layer and keep the chocolate glaze firm.
  • Brownies can be frozen for up to 2 months; thaw overnight in the refrigerator.
  • For cleaner cuts, slice while chilled using a warm knife (wipe between slices).
Serving Variations
  • Cut into bite-sized squares for party trays or dessert boards.
  • Garnish with crushed peppermint candies for a festive holiday twist.
  • Drizzle white chocolate over the top for elegant contrast and added sweetness.
Avoid Common Mistakes
  • Don’t spread mint frosting onto a warm brownie or it will melt and lose structure.
  • Ensure chocolate topping cools slightly before spreading to avoid melting the mint layer.
  • Don’t overbake the brownie layer — it should remain soft and fudgy.
  • Chill fully before slicing; warm brownies will cause smudged layers.
