Recipe Makes (Approximate): 16 brownies

Equipment

  • 9x9 baking dish
  • parchment paper
  • wire cooling rack
  • Stand mixer or hand mixer
  • Large bowl
  • Silicone spatula
  • Wax paper
  • Microwave safe bowl
  • Sharp knife

Ingredients

For the Brownies

  • 1 10.2-ounce bag Keto and Co Fudge Brownie Mix (or other preferred keto brownie mix, see Notes)
  • any ingredients needed to prepare brownies according to package instructions

For the Peppermint Buttercream

  • 6 tablespoons butter (melted)
  • 2 ⅓ cups Confectioners Swerve (one 12-ounce bag)
  • 3 tablespoons heavy cream
  • 1 teaspoon peppermint extract

For the Chocolate Ganache

  • 6 tablespoons butter (at room temperature, cut into small squares for ease)
  • 9 ounces sugar-free semi-sweet chocolate chips (like Lily's Semi-Sweet Style Baking Chips)
  • 1 teaspoon peppermint extract

Optional Toppings

  • sugar-free candy canes or peppermint candies (crushed)

Instructions

For the Brownies

  • Preheat oven to 350° Fahrenheit. Line 9x9 baking dish with parchment paper. Prepare brownie mix as instructed on package. Transfer batter to baking dish and bake 30 minutes (see Notes).
  • Once baked, let brownies cool in baking dish on wire rack. While brownies cool, prepare buttercream.

For the Peppermint Buttercream

  • In large bowl, use mixer to combine melted butter, Confectioners Swerve, heavy cream, and peppermint extract. Beat all ingredients together on medium speed until mixture is smooth.
  • When brownies are completely cooled, spread buttercream over top of brownies in one even layer. Press wax paper lightly on top of buttercream to smooth layer evenly if needed. Place brownies in refrigerator and chill 30 minutes.

For the Chocolate Ganache

  • Place butter and chocolate chips in microwave-safe bowl. Microwave in 30-second bursts, stirring well in between each burst, until chocolate is completely melted and smooth.
  • Stir peppermint extract into melted chocolate, then spoon ganache on top of chilled buttercream frosting.
  • Use silicone spatula to smooth out ganache into one even layer. If desired, top with crushed candy canes or peppermint candies, then return dish to refrigerator and chill until ganache is hardened.

  • Once hardened, use sides of parchment paper to lift brownies out of baking dish. To serve the brownies, use a sharp knife that's been warmed under hot running water. It'll slice through the ganache more smoothly than a cold or room temperature knife. Slice into 16 brownies and serve.

Recipe Notes

  • Brownies: How good your brownie mix is will dramatically change how moist your brownie layer is. I LOVE Keto and Co.'s Fudge Brownie mix, and it gave me totally perfect, moist brownies here. If you use another brand, like Miss Jones, I recommend baking them for 20 to 25 minutes, rather than 30 minutes as directed here. Leaving the brownies slightly underbaked will give you a fudgier, more moist brownie.
  • Chocolate: Be sure there is absolutely NO moisture at all on your microwave-safe bowl and silicone spatula for stirring. Even the tiniest bit of moisture can make the chocolate seize. If that happens, stirring in a little oil or melted butter can help it smooth back out.
