If you are looking for a cookie that is “magically delicious” and impossibly decadent, these Chocolate Mint Oreo Cookies are the ultimate treat. This recipe takes a rich, brownie-like chocolate base and packs it with chunky pieces of Mint Oreos and refreshing mint chocolate chips. It is the perfect dessert for St. Patrick’s Day, holiday cookie swaps, or any time you need a serious chocolate-peppermint fix.
The beauty of these mint chocolate cookies is the intense “double chocolate” experience.

Ingredients
- 1 cup Unsalted Butter, softened
- ¾ cup Granulated Sugar
- ¾ cup Light Brown Sugar, packed
- 2 Large Eggs, room temperature
- 2 tsp Vanilla Extract
- 1 tsp Peppermint Extract (optional, for extra punch)
- 2 cups All-purpose Flour
- ⅔ cup Dutch-process Cocoa Powder
- 1 tsp Baking Soda
- ½ tsp Salt
- 1 ½ cups Mint Oreo Cookies, coarsely chopped
- 1 cup Mint Chocolate Chips (or semi-sweet chips)
Instructions
1. Prep the Kitchen
Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone mats to ensure the cookies don’t stick to the pan.
2. Cream Butter and Sugars
In a large bowl, beat the softened butter, granulated sugar, and brown sugar together for 3–4 minutes until the mixture is light, fluffy, and pale in color.
3. Add Liquid Ingredients
Beat in the eggs one at a time, followed by the vanilla and peppermint extracts. Mix until well combined and smooth.
4. Mix Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.
5. Fold in the “Mix-Ins”
Using a sturdy spatula, gently fold in the chopped Mint Oreos and the mint chocolate chips by hand.
6. Scoop and Bake
Scoop rounded tablespoons of dough (about 2 tablespoons per cookie) onto the prepared sheets, spacing them 2 inches apart. Bake for 10–12 minutes. The cookies will look slightly soft in the center but will firm up as they cool.
7. Cool and Set
Let the cookies rest on the warm baking sheet for at least 5–10 minutes before transferring them to a wire rack to cool completely.
Expert Tips for Success
- Dutch-Process Cocoa is Key: For that deep, dark “Oreo” color and a smooth chocolate flavor, use Dutch-processed cocoa powder rather than natural cocoa powder.
- Don’t Over-Bake: Chocolate cookies are hard to judge by color. Take them out when the edges are set but the tops still look slightly “wet.” Over-baking will lead to a dry, crumbly cookie.
- The “Hand-Chop” Method: Don’t put the Oreos in a food processor! You want large, chunky pieces of cookie and mint cream to be visible in every bite.
- Room Temperature Eggs: Cold eggs can cause the butter to seize, resulting in a lumpy batter. Place cold eggs in a bowl of warm water for 5 minutes to take the chill off.
Variations
- White Chocolate Mint: Swap the mint chips for white chocolate chips to add a creamy, sweet contrast to the dark dough.
- Peppermint Crunch: Sprinkle crushed candy canes or peppermint bark on top immediately after baking for a festive winter twist.
- Mint Oreo Sandwiches: Use a mint buttercream frosting to sandwich two cookies together for an ultra-indulgent treat.
- The “Green” Version: Add a few drops of green gel food coloring to a white chocolate drizzle to decorate the tops for St. Patrick’s Day.
FAQ: Chocolate Mint Oreo Cookies
Q: Can I use regular Oreos? A: Yes. If you can’t find Mint Oreos, regular ones work perfectly. Just be sure to include the peppermint extract in the dough to maintain that minty flavor.
Q: Why is my dough so sticky? A: High cocoa powder content can make dough feel tacky. If it’s too difficult to handle, chill the dough in the refrigerator for 30 minutes before scooping.
Q: How do I store these? A: Store in an airtight container at room temperature for up to 5 days. These stay remarkably soft because of the high sugar and fat content.
Q: Can I freeze the baked cookies? A: Absolutely. These cookies freeze beautifully for up to 3 months. Thaw at room temperature for a few hours before serving.
