The Best Mint Brownie Cookies

There’s something magical about mint brownie cookies. The moment you bite into that chewy, chocolatey goodness laced with cool, refreshing mint, you’re transported to cozy winter nights, holiday gatherings, or that quiet afternoon when you just need a little pick-me-up. Mint brownie cookies are not just a dessert; they’re a sensory experience — rich, fudgy, and cooling all at once.

Growing up, mint and chocolate always marked the winter season for me. My grandmother would make trays of mint desserts around the holidays: mint chocolate fudge, thin mint bark, and of course, mint brownie cookies. We would gather in the kitchen, the scent of cocoa and peppermint filling the air, and wait eagerly for the first batch to come out of the oven. For her, it wasn’t just about the taste but about bringing people together, sharing stories over warm cookies and hot cocoa, and making memories that lasted long after the treats were gone.

Mint brownie cookies hold a special place in many kitchens because they combine two classics — brownies and mint — into one handheld delight. Whether you’re baking them for a holiday party, a bake sale, or just a quiet night at home, these cookies carry a sense of nostalgia and comfort that’s hard to beat.

How to Make Mint Brownie Cookies

Step-by-Step Instructions

Making mint brownie cookies feels like a comforting ritual. It starts with simple pantry staples and transforms into a kitchen filled with the aroma of chocolate and mint — a scent that brings everyone wandering in to see when they’ll be ready.

Step 1: Prepare the dough
Start by melting the butter, then whisk it together with both sugars until smooth. The melted butter gives these cookies their signature fudgy texture, almost like biting into a dense brownie. Stir in the eggs, vanilla, and peppermint extract, breathing in that fresh, minty scent as it mixes in.

Step 2: Mix the dry ingredients
In a separate bowl, combine the flour, cocoa powder, baking soda, and salt. Slowly fold the dry mixture into the wet ingredients, careful not to overmix. This dough is thick and rich, hinting at the chocolate explosion that’s about to happen.

Step 3: Add the chocolate pieces
Gently fold in the semi-sweet chocolate chips and chopped mint chocolate. I love sneaking a few pieces as I go — it’s part of the fun! These little pockets of chocolate melt into the dough, creating gooey bursts of flavor.

Step 4: Chill the dough
Cover the dough and let it chill for at least 30 minutes. This step is key to getting that perfect crackly top and chewy center.

Step 5: Bake to perfection
Scoop the dough onto a lined baking sheet, leaving room for them to spread. Bake at 350°F (175°C) for 10–12 minutes, until the edges are set but the centers still look soft. Let them cool on the pan — they’ll continue to set as they rest.

Helpful Tips

• Chill the dough: Don’t skip this! Chilling helps control spread and gives the cookies their brownie-like texture.
• Use good cocoa powder: High-quality cocoa makes a noticeable difference in flavor.
• Adjust the mint: If you prefer a milder mint flavor, use slightly less peppermint extract or opt for more mint chocolate pieces instead.
• Store properly: Keep them in an airtight container to maintain their softness for several days.
