Frosted Peppermint Brownies

If there’s one thing that screams Christmas time, it’s anything with peppermint. It’s the ultimate Christmas flavor and tastes especially delicious mixed with chocolate. That’s where these chocolate peppermint brownies come in. They combine the best of both worlds and are super easy to whip up, making them the perfect treat to indulge in this holiday season.

These brownies are everything you dream of in a dessert…rich, gooey, fudgy, sweet and loaded with fresh peppermint flavor. They’re topped with a creamy peppermint frosting and then finished off with a layer of silky smooth chocolate ganache. With three amazing layers, each bite of these peppermint brownies is absolute heaven.

3 Delicious Layers

  • Brownies. This recipe starts off with a layer of brownies. You can use your favorite box mix, or make homemade brownies or fudge brownies from scratch. Both ways taste delicious!
  • Frosting. Next comes the creamy peppermint frosting. It tastes similar to a classic buttercream, but with a hint of peppermint flavor to give it that festive holiday flare.
  • Ganache. Last comes a layer of silky chocolate ganache, because doesn’t want double the chocolate? It’s the perfect finishing touch and makes these brownies next level delicious.

Finish Them Off!

After adding the chocolate ganache, I love to sprinkle some crushed peppermint candies on the tops. It adds a nice crunch and makes them look extra festive. You could also add some fun holiday sprinkles to give it some color.

Baking Tips + Variations

  • For thinner brownies, you can use a 9×13″ baking dish. You will likely need to shorten the baking time to around 20 to 25 minutes. You may also need a bit more frosting.
  • For even more chocolate flavor, mix 1/2 cup chocolate chips into the batter.
  • A cream cheese frosting or marshmallow frosting would also taste delicious on top.
  • After adding the ganache, allow the bars to cool completely before slicing so that the tops don’t crack.
  • You could skip the ganache layer if preferred. Or try drizzling it over the frosting instead of spreading completely on top.

How to Store Peppermint Brownies

Slice and store any leftovers in an airtight container at room temperature. They will stay fresh for up to 3 days. You may also freeze the brownies for up to 3 months. Simply cut into squares, then wrap in foil or plastic wrap and store in a freezer container. Thaw at room temperature for a few hours when ready to enjoy.
