Why this recipe works
- A one bowl rich chocolate syrup brownie is the base
- Adjust the amount of flavor in the peppermint buttercream to suit your liking
- The rich chocolate fudge topping and candy cane sprinkles make this minty dessert go from good to yummm...
I have been collecting recipes for over 40 years.
Because everything is online now, I rarely go back to my paper recipes. When I do look for an old recipe, it's fun to see what I find. Case in point, I ran across this old beauty for Hershey's Double Chocolate Mint Dessert. I've made it many times over the years.
Now we're dressing it up for the holidays by using brownies made with homemade chocolate syrup and adding a little crushed candy canes for additional minty goodness and crunch. Friends, I give you my Double Chocolate Peppermint Brownies.
[Side note: I say "we" because my younger daughter is home for a few weeks and we love baking together. She's the one who designed her sister's wedding cake and her brother-in-law's groom's TARDIS cake. ]
We all know that chocolate and mint are a winning combination (witness Mint Chocolate Chunk Cookies). These Double Chocolate Peppermint Brownies are no exception.
The crushed candy canes add a merry touch to the layers of rich chocolate brownie, cool peppermint buttercream, and fudgy chocolate topping. They really brighten a holiday dessert plate!
I hope Double Chocolate Peppermint Brownies make an appearance at your holiday celebrations.
Happy Christmas, Happy Hanukkah, Happy Kwanzaa, Happy Solstice, Happy Hogmanay, and/or Happy whatever-you-celebrate!

Recipe Ingredients
You'll need the following ingredients to make this chocolate peppermint brownie recipe:
Ingredient Notes
The basic ingredients are pantry staples: flour, sugar, eggs, butter, chocolate, and powdered sugar.
Chocolate syrup: You can use either homemade or store bought chocolate syrup for the brownie base. Making homemade chocolate syrup is very quick and easy, and only uses 5 ingredients. It tastes just like what you can buy at the store without all the preservatives. Sorry, Hershey's!
Peppermint extract: it's important to keep in mind that peppermint extract can quickly ruin a dessert if you use too much. Start the buttercream with ¼ teaspoon of the extract, then taste to see if you'd like more. Also, remember that chilling will dampen the flavor a bit.
Chocolate: For this recipe, you can use chocolate wafers, a chopped solid chocolate bar, or chocolate chips.
Candy canes: Adds a crunchy burst of minty flavor in the filling and on the topping.

How to make layered peppermint brownies
Similar to Nanaimo Bars, this peppermint brownie recipe is made in three distinct layers. The actual hands-on work time is minimal. However, you'll want to give yourself enough time for everything to chill before moving on to the next layer.
Step 1: Make the brownie layer
Cream the butter and sugar together until smooth. Add the flour, eggs, and chocolate syrup and beat just until no lumps remain (photo 1).
Bake the brownie in an 8- x 8-inch baking pan sprayed with baking spray and lined with parchment paper at 350°F for 20 to 25 minutes (photo 2).
Notice the binder clips on the parchment paper? That helps to keep it from drooping into the batter as it bakes.
Cool the brownie completely in the pan by bringing it to room temperature for 30 minutes, then chill in the refrigerator for another 15 minutes.
Step 2: Make the peppermint buttercream layer
Here you get to take out your aggressions on some poor, unsuspecting candy canes. Place the unwrapped candy canes into a ziplock bag and pound with a meat mallet until you have some pieces and some dust (photo 3).
The amount will depend on your mental state, of course!
The peppermint layer is made like buttercream frosting. Beat the powdered sugar, butter, water, and peppermint extract together until smooth. If you want, stir in a few drops of red food coloring, then fold in 1 to 2 teaspoons of the crushed candy canes (photo 4).
Spread the peppermint buttercream on the chilled brownie layer and sprinkle on some additional crushed candy canes. Chill until the peppermint buttercream layer is firm (photo 5).
Step 3: Make the chocolate fudge topping
The chocolate fudge topping is just dark chocolate melted with butter. The butter allows the chocolate to set more firmly than a simple chocolate ganache (photo 6).
Melt the chocolate with the butter on HIGH for about 60 to 90 seconds or until the chocolate is mostly melted (heat additionally at 20 second increments if needed). Stir until the mixture is smooth.
Alternatively, add the chocolate and butter to a saucepan or large bowl set above 1-inch of simmering water, being careful that the bottom of the pan or bowl isn't sitting in the water itself and being careful that no water gets in the chocolate. Stir until the mixture is smooth.
Spread the chocolate fudge on top of the chilled buttercream layer, then sprinkle on the remaining crushed candy. Chill to let the chocolate fudge layer set (photo 7).
Step 4: Cut into squares
Remove the brownie slab from the baking pan using the parchment paper as a sling, and cut it into sixteen 2- x 2-inch squares (photo 8).
Storage and make-ahead instructions
Storage instructions: Store the squares in an airtight container in the refrigerator for up to a week. Serve them chilled for the best texture, and enjoy the minty goodness!
For longer storage, wrap the chilled squares in two layers of plastic wrap, then a layer of foil (or put in a ziplock bag) and keep in the freezer. Allow them to defrost on the counter for 30 minutes before serving.
Make-ahead instructions: You can store both the chilled baked brownie base, wrapped tightly in plastic wrap, and the peppermint buttercream, stored in an airtight container, in the refrigerator a few days ahead. Allow the buttercream to come to room temperature, then stir to smooth it out before using.
How to cut brownies cleanly
In order to get clean cuts when you're cutting a slab into squares or bars, dip your knife into hot water and wipe it dry between each cut. This will keep the knife from tearing the baked good from any leftover crumbs on the knife.
Questions asked and answered
Here are some questions you might have...
Peppermint extract has menthol, which intensifies its flavor. Mint extract contains a mixture of peppermint and spearmint flavors. I prefer peppermint extract to avoid the "toothpaste taste" that spearmint can sometimes add.
Not to worry! The batter for the brownie layer will be thin because the chocolate syrup contains water, something not found even in a cakey brownie recipe. The chocolate syrup gives this brownie layer deep chocolate flavor and a lighter, cake-like texture.
Yes! You can double the ingredient amounts and bake the brownie layer in a 9- x 13-inch baking pan for 25 to 30 minutes. Cut the brownies into 24 squares.

These were delicious! I wonder how they would work if you did them as chocolate orange with that orange extract you've talked about!
Tammy says
Oooh...neat idea! If you try it, please let me know how it goes 😉

Mint chocolate is always a great combination, and using buttercream and ganache? These are dangerous!
