Ingredients You’ll Need

- ¼ cup dark chocolate unsweetened cocoa powder: This lends a deep chocolate flavor. Make sure it’s high quality for the best taste!
- ½ cup vegetable oil: Helps keep the brownies moist and fudgy. You can substitute with melted coconut oil for a different flavor.
- 2 cups granulated sugar: Sweetens the brownies beautifully. No substitutes recommended here for this particular texture.
- 2 large eggs: Brings the richness and helps bind the ingredients. Room temperature eggs will make for a smoother batter.
- ¼ cup buttermilk: Adds moisture and a slight tang. If you don’t have buttermilk, mix ¼ cup milk with a teaspoon of vinegar.
- 2 cups all-purpose flour: The base for the brownie structure. For gluten-free alternatives, use a gluten-free all-purpose flour blend.
- 1 teaspoon baking soda: Helps the brownies rise slightly for that perfect texture.
- ½ teaspoon kosher salt: Enhances the chocolate flavor deliciously.
- 1 cup Andes crème de menthe baking chips: Infuses the brownies with a delightful minty flavor. If unavailable, you can use mint chocolate chips.
- ½ cup unsalted butter (softened): For the frosting, gives a creamy base. Make sure it’s at room temperature for easy mixing.
- ½ cup milk: Helps achieve a smooth consistency in the frosting. Use dairy-free milk if preferred.
- 4 cups powdered sugar: Sweetens and thickens the frosting. Sift before measuring for the best results.
- ½ teaspoon peppermint extract: A little goes a long way for that fresh mint flavor in the frosting.
- 1 drop green food coloring: Adds visual appeal. Use gel colors for a more vibrant look.
- ¾ cup mini semi-sweet chocolate chips: A delightful addition to the frosting for some texture.
How to Make Mint Chocolate Chip Brownies with Green Swirl Frosting
Preheat the oven: Start by preheating your oven to 400°F (200°C). Prepare a 13×9 inch baking dish by lining it with parchment paper for easy removal.
Melt the ingredients: In a small saucepan over medium-high heat, combine the ½ cup of unsalted butter, ¼ cup of unsweetened cocoa powder, and ½ cup of vegetable oil. Whisk continuously as the mixture comes to a boil; then remove it from the heat.
Mix the wet ingredients: In a large mixing bowl, combine 2 cups of granulated sugar, 2 large eggs, and ¼ cup of buttermilk. Slowly add the melted butter mixture while stirring gently. Be careful not to over mix; just combine them until blended.
Combine dry ingredients: Stir in the 2 cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of kosher salt, mixing just until incorporated. Fold in 1 cup of Andes crème de menthe baking chips for that special minty surprise.
Bake the brownies: Pour the brownie batter into the prepared baking dish, spreading it evenly. Bake for about 20 minutes or until the edges look firm, and a toothpick inserted comes out with a few moist crumbs.
Cool the brownies: Once done, remove the brownies from the oven and allow them to cool completely in the baking dish.
Prepare the frosting: In a large mixing bowl, beat ½ cup of softened unsalted butter using an electric mixer for 3-4 minutes until it becomes pale. Gradually add in ½ cup of milk, 4 cups of powdered sugar, ½ teaspoon of peppermint extract, and the drop of green food coloring. Continue beating for an additional 3-5 minutes until the frosting is light and fluffy. If it’s too thick, add more milk until you reach a spreadable consistency.
Add chocolate chips: Gently fold in the ¾ cup of mini semi-sweet chocolate chips to the frosting for a delightful crunch.
Frost the brownies: Spread the frosting generously over the cooled brownies. For a nice touch, you can create swirls with a knife for a more playful look.
Chill and serve: Refrigerate the brownies for about 2 hours until the frosting is set. Once firm, cut them into squares and enjoy!

Storing & Reheating
Store your Mint Chocolate Chip Brownies with Green Swirl Frosting in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for about a week. If you’d like to extend their life even further, you can freeze the brownies for up to 3 months. Just wrap them securely in plastic wrap and aluminum foil. When you’re ready to enjoy, let them sit at room temperature for about 10-15 minutes or microwave for about 10 seconds to revive that chewy texture. Keep in mind that the frosting may soften a bit after freezing, but the flavor will remain intact.
Chef’s Helpful Tips
- Make sure the butter for your brownies is melted but not too hot; this will prevent cooking the eggs when combined.
- If your batter seems too thick, a splash more of buttermilk can help loosen it up, resulting in a fudgier brownie.
- Use room temperature ingredients for the frosting for a fluffier texture; cold butter can lead to lumps.
- For extra minty goodness, increase the peppermint extract in the frosting slightly, adjusting to your flavor preference.
- If you want to prep ahead, make and frost the brownies a day in advance; just keep them covered in the fridge until served.
The rich, fudgy brownies entwined with refreshing mint and topped with fluffy green frosting create a dessert that’s simply irresistible. Each component complements the others, encouraging you to relish in the delightful balance of flavors and textures. Don’t hesitate to experiment with flavors or additional toppings when you make your batch. It’s a treat that’s all about joy and creativity in the kitchen, so I invite you to dive in and enjoy!
Recipe FAQs
Can I make these brownies ahead of time?
Absolutely! You can prepare these brownies a day or two ahead of your event. Just store them in an airtight container in the fridge once frosted, giving the flavors time to meld together beautifully.
What can I use instead of Andes crème de menthe baking chips?
If you can’t find them, mint chocolate chips are a great alternative. You could also chop up mint-filled chocolates or use chocolate chips mixed with a touch of mint extract for a different flavor profile.
How do I make the brownies less sweet?
To reduce the sweetness, you can cut back on the sugar in the brownie batter by a ¼ cup and use a high-quality dark cocoa powder. This will create a more balanced, less sugary dessert.
Are these brownies gluten-free?
Yes! You can easily swap the all-purpose flour for a gluten-free flour blend. Be sure to check that your baking chips are also gluten-free to keep the entire dessert compliant.
