Peppermint combined with chocolate is the ultimate holiday flavor. When coffee shops start making their Peppermint Mochas available it feels like the start of the holiday season. And a Peppermint Mocha in brownie form is absolutely epic. These super fudgy Peppermint Mocha Brownies are so simple to make, coming together in a matter of minutes in just one bowl - no mixer required!
This quick and easy recipe is rich and decadent and perfect for the holidays. These festive treats make great gifts and are the perfect contribution to holiday potlucks, fun bake-offs, or your Christmas party dessert table!

Why this Recipe Works
Peppermint extract often can give a potent peppermint flavor to baked goods, so these Peppermint Mocha Brownies don't use extract, but instead use a layer of peppermint bark to give the perfect pop of peppermint flavor.
Ingredients and Notes
Espresso Powder - Be sure to use instant espresso powder. That will ensure the granules dissolve in the brownie batter.
Peppermint Bark - I like to use Ghirardelli Peppermint Bark Squares simply because they fit perfectly in the 8x8 pan, but any peppermint bark will work!
Substitutions
Vegetable Oil - The consistency of the vegetable oil contributes to the fudgy texture of these Peppermint Mocha Brownies, but it can be replaced with additional melted butter.
Espresso Powder - The espresso powder can be skipped to have chocolate peppermint brownies instead of peppermint mocha brownies.
Peppermint Bark - Store-bought or homemade peppermint bark will work, but you can also use peppermint chips or a mix of peppermint and chocolate chips and mix them into the batter instead of layering them.
How to Make this Recipe
Step 1: Heat milk and butter until the butter is melted and the milk is warm.
Step 2: Add cocoa powder and oil and mix until well combined.
Step 3: Stir in eggs, then stir in sugar.
Step 4: Add flour, espresso powder, and salt, and mix until combined.
Step 5: Pour about half the mixture into a parchment lined 8x8 pan, then cover with a layer of peppermint bark, then pour the remaining batter on top.
Step 6: Bake at 350°F for about 30 minutes, then cool completely in pan, cool overnight if possible. Cut into squares and enjoy!
Recipe FAQs
These Peppermint Mocha Brownies are extra fudgy due to the combination of melted butter and vegetable oil. Recipes that have more fat than flour will generally be fudgier whereas brownies with more flour than fat are usually cakier.
These brownies are so gooey inside that letting them rest overnight allows them to reach the perfect texture. If you cut them while they're still warm, they may fall apart and you'll need to dive in with a fork! But as they cool they will set and form perfect, fudgy bars.
I recommend doing that for these Peppermint Mocha Brownies. This allows them to set up perfectly, creating the best fudgy brownie texture. After that, they should be stored in an airtight container at room temperature.
These Peppermint Mocha Brownies are super fudgy and gooey, so the common toothpick test is not the most reliable. Instead, I suggest keeping an eye on the edges of the brownies until they look baked.
Tips & Tricks
Tip #1: If melting your butter and heating milk on the stovetop, use a medium to large saucepan so the brownie batter can be prepped in the saucepan. Similarly, if melting the butter in a microwave, use a medium microwave-safe mixing bowl so that the batter can be made all in one bowl.
Tip #2: Add the cocoa powder while the butter and milk are still hot. It will help the cocoa powder to dissolve into the mixture.
Tip #3: Be sure the brownies have fully cooled before cutting.
Storage Tips
Peppermint Mocha Brownies should be stored in an airtight container at room temperature and should last for about 5-7 days.
