Ingredients You’ll Need
These ingredients are straightforward yet essential, each one playing a vital role to achieve the perfect texture, flavor, and bright minty finish of the Mint Chocolate Brownie Cupcakes. From smooth semisweet chocolate to the refreshing peppermint patties, every item is selected to create a luscious and memorable dessert experience.
- Semisweet chocolate (8 ounces, chopped): Melts into the batter for rich, deep chocolate flavor and fudgy texture.
- Unsalted butter (8 tablespoons, cut into chunks): Adds creaminess and helps bind ingredients together for that perfect moist crumb.
- Granulated sugar (1 cup): Sweetens the batter while promoting a tender bite.
- Salt (3/4 teaspoon): Enhances the chocolate notes and balances sweetness.
- Espresso powder (1/2 teaspoon, optional): Boosts the chocolate flavor without adding a coffee taste.
- Eggs (3 large): Provide structure and richness that make these cupcakes irresistibly moist.
- All-purpose flour (1/2 cup): Keeps the cupcake base tender yet firm.
- Unsweetened cocoa powder (1/4 cup, sifted): Deepens chocolate intensity and adds that classic brownie look.
- Peppermint patties (12 small, 1 1/2-inch): The magical minty center that melts into the cupcake for a surprise burst of coolness.
- Powdered sugar (3 to 3 1/2 cups): Sweetens and thickens the frosting to a luscious, pipeable consistency.
- Whole milk or heavy cream (2 to 4 tablespoons): Creates the creamy softness that balances powdered sugar in the frosting.
- Peppermint extract (1/2 teaspoon): Infuses the frosting with invigorating mint flavor that complements the peppermint center.
- Salt (1/4 teaspoon): Elevates and rounds out the frosting’s sweetness.
How to Make Mint Chocolate Brownie Cupcakes
Step 1: Prepare the Batter
Start by heating your oven to 350 degrees and lining a 12-cup muffin tin with cupcake liners. Melt the chopped semisweet chocolate and butter together in a microwave-safe bowl, heating in 30-second bursts while stirring after each. This ensures a smooth, glossy mixture without scorching the chocolate. Allow this blend to cool for 5 minutes to avoid cooking the eggs in the next step.
Step 2: Combine Wet and Dry Ingredients
Whisk the sugar, salt, and optional espresso powder into the cooled chocolate and butter mixture. The espresso powder subtly intensifies the chocolate flavor, creating a complex and rich taste. Next, add the eggs one at a time, beating well after each addition to create a luscious, thick batter. Carefully whisk in the flour and sifted cocoa powder until the batter is just smooth – be gentle to keep it fudgy and tender rather than cakey.
Step 3: Assemble the Cupcakes
Into each prepared liner, spoon about one tablespoon of batter to form the base layer. Then place one peppermint patty on top – this minty surprise will melt beautifully during baking. Cover the patty with the remaining batter, making sure it completely surrounds the peppermint to keep that wonderful middle intact. This layering is crucial for that amazing gooey mint pocket inside.
Step 4: Bake to Perfection
Bake the cupcakes for 32 to 36 minutes. To test doneness, insert a toothpick just into the cake part (not the patty) to make sure it comes out with a few moist crumbs — too much batter on the toothpick means more baking is needed. Once baked, transfer the pan to a wire rack and let your Mint Chocolate Brownie Cupcakes cool completely to ensure the frosting adheres smoothly.
Step 5: Make the Mint Frosting
While your cupcakes cool, prepare the frosting by beating unsalted butter on low speed until creamy using a stand mixer fitted with a paddle attachment. Gradually add powdered sugar, milk, peppermint extract, and salt while blending on low, then increase speed to high for 3 minutes to achieve a light, fluffy texture. Adjust the consistency by adding more powdered sugar if too thin or milk if too thick.
Step 6: Frost and Decorate
Once completely cooled, generously frost each cupcake with the minty frosting. This final touch brings everything together with a smooth, sweet finish that perfectly complements the brownie base and mint center.
How to Serve Mint Chocolate Brownie Cupcakes

Garnishes
These cupcakes shine on their own, but for extra flair, sprinkle a few crushed peppermint candies or chocolate shavings on top of the frosting. Fresh mint leaves work beautifully too, adding vibrant color and an herbal aroma that invites guests to indulge.
Side Dishes
Your Mint Chocolate Brownie Cupcakes pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream to balance the rich chocolate and cool mint flavors. A cup of hot coffee or mint tea also complements them perfectly, creating a cozy and delightful dessert experience.
Creative Ways to Present
Consider serving these cupcakes on a rustic wooden platter with a sprinkle of crushed peppermint around the edges for a festive look. You can also pipe the frosting into elegant swirls and top with tiny edible silver beads for a fancy occasion. Mini cupcake stands or individual glass cloches add a whimsical touch for parties.
Make Ahead and Storage
Storing Leftovers
Mint Chocolate Brownie Cupcakes stay fresh in an airtight container at room temperature for up to two days. If you want to keep them a bit longer, storing them in the fridge is perfect, but allow them to come to room temperature for the best texture and flavor before serving.
Freezing
You can freeze these cupcakes without frosting by wrapping them tightly in plastic wrap and placing them in a freezer-safe container or zip-top bag. They’ll stay delicious for up to three months. Frost them after thawing, which you should do overnight in the fridge to preserve the delicate mint flavor and cupcake texture.
Reheating
If you prefer your Mint Chocolate Brownie Cupcakes slightly warm, microwave them for about 10 to 15 seconds. This quick warm-up intensifies the fudgy chocolate and helps the mint center soften, making each bite melt in your mouth even more. Avoid overheating to keep the frosting intact.
FAQs
Can I use dark chocolate instead of semisweet chocolate?
Absolutely! Dark chocolate will give your Mint Chocolate Brownie Cupcakes a richer and slightly more intense flavor. Just keep in mind that it might make the cupcakes a bit less sweet, so you can increase the sugar slightly if you prefer.
What if I don’t have peppermint patties?
You can substitute with chopped peppermint candies or even Andes mints for a similar effect. Just make sure to adjust the size so they fit nicely in the cupcake without overflowing during baking.
Is the espresso powder necessary?
Espresso powder is optional but highly recommended because it enhances the chocolate flavor without imparting a coffee taste, making your cupcakes taste even more decadent and complex.
Can I make the frosting without peppermint extract?
If you’re out of peppermint extract, vanilla extract is a good alternative, though it won’t give the same refreshing mint kick. You could also add a few drops of mint-flavored liqueur for an adult twist.
How do I prevent the peppermint patties from sinking?
To keep the peppermint patties from sinking during baking, start with a small layer of batter at the bottom, gently place the patty, and then carefully spoon remaining batter on top without aggressive stirring to maintain the cupcake’s structure around the mint.
Final Thoughts
Trust me when I say, once you try these Mint Chocolate Brownie Cupcakes, they’ll become a new favorite to bake and share.
