Units Scale
  • 1 box mix of Brownies – Ghirardelli Dark Chocolate Brownie Mix
  • 1/4 cup Water
  • 1/2 cup of Oil
  • 1 Egg
  • (or the ingredients on your box mix)

Buttercream Frosting:

  • 4 tablespoons of butter at room temperature not melted.
  • 2 cups of confectioners sugar
  • 2 tablespoons of milk
  • 1/4 to 1/2 teaspoon peppermint extract (depending on how minty you want your frosting)
  • 1 drop of red food coloring for red (or green food coloring for Christmas or St. Patrick’s Day)

Top Chocolate Layer:

  • 1 cup of semi-sweet chocolate chips
  • 2 tablespoons of butter


  1. Line a 13 x 9 glass baking dish with parchment paper. This allows you to easily lift the brownies out of the dish when you are ready to cut.
  2. Bake the brownies per the instructions on the brownie mix box.
  3. Remove from the oven when the time is over and cool completely. Do not cheat on this step. If they are even warm the top will melt.
  4. Next, make the frosting to the top.
  5. Mix in a stand mixer or hand mixer the butter, sugar, milk peppermint extract, and the food coloring. Add more sugar if the frosting is not stiff enough.
  6. Frost the top of the brownies and put them in the refrigerator for one hour to set.
  7. When the frosting is set make the melted chocolate for the top.
  8. Melt the chocolate chips in the microwave for 30 seconds at a time until melted. Do not overheat.
  9. Mix in the butter to make a smooth glossy topping. Use extra butter in the chocolate is too think. (do not get any water in the chocolate as it will bind up into a mess)
  10. Top the frosting with the melted chocolate and with an offset spatula spread evenly over the frosting.
  11. Put the pan of brownies in the refrigerator again for 30 to 45 minutes to set.
  12. When set remove the brownies from the pan and put on a cutting board to cut into squares.
