Ingredients You’ll Need

- ¼ cup dark chocolate unsweetened cocoa powder: Adds a deep chocolate flavor. You can substitute it with high-quality chocolate if needed.
- ½ cup vegetable oil: Keeps your brownies moist while ensuring a lovely texture; can be swapped with melted coconut oil for a different taste.
- 2 cups granulated sugar: Sweetness is key! If you’re looking for a less sweet option, try using coconut sugar.
- 2 large eggs: Binding agent for the ingredients. Be sure they are at room temperature for easier incorporation.
- ¼ cup buttermilk: Adds moisture and a slight tanginess; you can use sour cream as a substitute if you’re in a pinch.
- 2 cups all-purpose flour: Provides structure to the brownies; whole wheat flour works for a denser texture.
- 1 teaspoon baking soda: Leavens the brownies, contributing to their nice rise; don’t skip this one!
- ½ teaspoon kosher salt: Enhances flavors wonderfully; table salt is fine, but reduce the amount slightly.
- 1 cup Andes crème de menthe baking chips: These are a must for that minty goodness! If unavailable, peppermint chips can be substituted.
- ½ cup unsalted butter (for frosting): Adds creaminess to the frosting. Make sure it’s softened for easy mixing.
- ½ cup milk: Helps achieve the consistency you desire in your frosting. Feel free to use almond or oat milk for a non-dairy option.
- 4 cups powdered sugar: Sweetens the frosting; sift it to avoid lumps for a smoother finish.
- ½ teaspoon peppermint extract: Boosts the minty flavor; use a little more or less depending on your preference.
- 1 drop green food coloring: Adds that fun color; adjust as needed to achieve your desired shade.
- ¾ cup mini semi-sweet chocolate chips: These little gems are perfect for a burst of chocolate in every bite!
How to Make Mint Chocolate Chip Brownies with Green Swirl Frosting
Preheat Oven: Start by preheating your oven to 400°F (200°C). This ensures a warm environment for the brownies to bake evenly.
Prepare Baking Dish: Line a 13×9 inch baking dish with parchment paper. This step makes it super easy to lift the brownies out when they’re done baking.
Combine Ingredients: In a small saucepan over medium-high heat, combine ½ cup unsalted butter, ¼ cup dark chocolate unsweetened cocoa powder, and ½ cup vegetable oil. Bring this mixture to a boil while whisking continuously until it’s bubbling and fragrant, then remove from heat.
Mix Brownie Batter: In a large mixing bowl, combine 2 cups granulated sugar, 2 large eggs, and ¼ cup buttermilk. Pour in the warm butter mixture slowly and stir gently to combine. Be sure not to overmix; you want a tender brownie!
Incorporate Dry Ingredients: Add in 2 cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon kosher salt. Stir until just combined, folding in 1 cup of Andes crème de menthe baking chips at the end.
Bake Brownies: Pour the brownie batter into the prepared baking dish and bake for 20 minutes, or until the edges are slightly firm and a toothpick inserted in the center comes out clean.
Cool Brownies: Once baked, remove from the oven and allow to cool in the pan for a bit before transferring them to a wire rack to cool completely.
Make Frosting: In a large mixing bowl, use an electric mixer to beat ½ cup unsalted butter on medium speed for about 3-4 minutes until it’s pale and fluffy. Slowly add ½ cup milk, then gradually mix in 4 cups powdered sugar and ½ teaspoon peppermint extract. If needed, adjust the consistency with more milk until you reach the desired fluffiness. Finally, fold in ¾ cup mini semi-sweet chocolate chips.
Frost Brownies: Once the brownies are totally cool, spread the light and airy frosting over the top. If you want it to look extra special, use a piping bag!
Chill & Serve: Refrigerate the frosted brownies for at least two hours. This helps the frosting set beautifully. After chilling, cut into squares and enjoy these delightful treats!

Storing & Reheating
Store your brownies in an airtight container at room temperature for up to 4 days. For longer storage, keep them in the fridge for up to a week, ensuring they’re sealed tightly. If you’d like to freeze them, wrap each brownie separately in butcher paper or plastic wrap and then place them in a freezer-safe container. They can be frozen for up to 3 months. To enjoy them again, simply thaw at room temperature for a few hours or warm in the microwave for about 15 seconds to refresh their texture—just be careful not to overheat!
Chef’s Helpful Tips
- Take care to mix the batter gently. Overmixing can lead to tough brownies.
- Always weigh your flour, if possible, to ensure accuracy; too much flour can lead to dry brownies.
- Keep the ingredients at room temperature, especially the eggs and buttermilk; this helps them blend more smoothly into the batter.
- If you want a stronger mint flavor, feel free to add a little extra peppermint extract in the frosting, just a drop at a time to avoid overwhelming it.
- These brownies are great to make ahead; they often taste even better the next day as the flavors meld together.
