Ingredients Method Notes

Ingredients

  

• For the Brownie Cookie Dough:
• * 1/2 cup unsalted butter
• * 8 ounces semi-sweet chocolate chopped
• * 2 large eggs room temperature
• * 1 cup granulated sugar
• * 1 teaspoon vanilla extract
• * 3/4 cup all-purpose flour
• * 1/4 cup unsweetened cocoa powder
• * 1 teaspoon baking powder
• * 1/4 teaspoon salt
• For the Mint Swirl:
• * 1/2 cup white chocolate chips
• * 1 teaspoon peppermint extract
• * 1-2 drops green food coloring optional

Method

 

1. Preheat the oven to 350°F. Line two baking sheets with parchment paper.
2. Melt the butter and semi-sweet chocolate together in a microwave-safe bowl, stirring until smooth. Allow the mixture to cool slightly.
3. In a large mixing bowl, beat the eggs and sugar until light and slightly thickened. Mix in the vanilla extract.
4. Slowly add the melted chocolate mixture to the egg mixture and stir until fully combined.
5. In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
6. Fold the dry ingredients into the chocolate mixture until a soft brownie batter forms.
7. Melt the white chocolate chips and stir in the peppermint extract. Add food coloring if desired.
8. Scoop tablespoon-sized portions of brownie dough onto the prepared baking sheets, leaving space between each cookie.
9. Place a small spoonful of the mint mixture on top of each cookie and use a toothpick to gently swirl it into the dough.
10. Bake for 10-12 minutes, or until the tops are shiny and crackled.
11. Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

* Use peppermint extract sparingly, as it can quickly overpower the chocolate flavor.
* For a richer cookie, use dark chocolate instead of semi-sweet chocolate.
* The dough is soft, which helps create the fudgy brownie texture.
* Store cookies in an airtight container at room temperature for up to 4 days.
* These cookies freeze well for up to 2 months.
* Add mini chocolate chips to the batter for extra chocolate flavor.

How To Make Mint Chocolate Swirl Brownie Cookies

Step 1: Prepare the Baking Sheets

Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper and set them aside. This helps prevent sticking and makes cleanup much easier.

Step 2: Melt the Chocolate and Butter

In a microwave-safe bowl, combine the butter and semi-sweet chocolate. Heat in short intervals, stirring between each one, until smooth and glossy. Let the mixture cool slightly before moving on.

Step 3: Beat the Eggs and Sugar

In a large mixing bowl, beat the eggs, granulated sugar, and vanilla extract until the mixture becomes pale, thick, and slightly fluffy. This step helps create the signature crackly brownie-cookie tops.

Step 4: Combine the Wet Ingredients

Slowly pour the cooled chocolate mixture into the egg mixture while stirring continuously. Mix until everything is fully incorporated and smooth.

Step 5: Add the Dry Ingredients

Whisk together the flour, cocoa powder, baking powder, and salt in a separate bowl. Gradually fold the dry ingredients into the chocolate mixture until no dry streaks remain.

Step 6: Create the Mint Swirl

In a small bowl, prepare a mint chocolate mixture using melted white chocolate and a few drops of mint extract. If desired, add a drop of green food coloring for a festive swirl effect.

Step 7: Portion the Cookie Dough

Scoop portions of brownie cookie dough onto the prepared baking sheets, spacing them about 2 inches apart. Add small spoonfuls of the mint mixture on top of each cookie.

Step 8: Swirl the Tops

Use a toothpick or skewer to gently swirl the mint mixture into the brownie dough. Avoid overmixing so the swirls remain visible after baking.

Step 9: Bake the Cookies

Bake for 10–12 minutes, or until the tops are shiny and crackly while the centers still look slightly soft. The cookies will continue setting as they cool.

Step 10: Cool and Serve

Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack. Once completely cooled, serve and enjoy their fudgy texture and refreshing mint-chocolate flavor.

The Bottom Line

If you’re a fan of the classic combination of mint and chocolate, these Mint Chocolate Swirl Brownie Cookies deserve a spot on your baking list. With their fudgy texture, eye-catching swirls, and refreshing mint flavor, they’re the kind of cookie that disappears fast from dessert trays and cookie jars alike.
