I started making these cookies on a whim, honestly. It was during Girl Scout cookie season, and I had a few too many boxes of Thin Mints (if there’s such a thing). The idea hit me: what if I wrapped them in a thick, brownie-like cookie dough? The results were so decadent, I’ve made them for every holiday, birthday, and bake sale since.

What Ingredients You Will Need

This recipe uses classic, straightforward ingredients to create that fudgy, minty magic. You probably have most of these on hand—except maybe the Thin Mints (but I won’t judge if you stash a box year-round!). Here’s what you’ll need for these Thin Mint Stuffed Chocolate Mint Cookies:

• For the Cookie Dough:
  • All-purpose flour – 1 1/4 cups (150g) (gives the cookies structure without making them dry)
  • Unsweetened cocoa powder – 1/2 cup (50g) (Dutch-process preferred for richer flavor, but regular works too)
  • Baking soda – 1/2 teaspoon (for a little lift and chewiness)
  • Salt – 1/2 teaspoon (balances sweetness and amps up chocolate flavor)
  • Unsalted butter – 1/2 cup (113g), softened (room temperature is key)
  • Brown sugar – 1/2 cup (100g), packed (adds moisture and a caramel note)
  • Granulated sugar – 1/4 cup (50g) (for a crisp edge)
  • Large egg – 1 (binds everything together)
  • Peppermint extract – 1 teaspoon (don’t use mint extract—it can taste like toothpaste; trust me!)
  • Pure vanilla extract – 1/2 teaspoon (rounds out the flavor)
  • Mini chocolate chips – 2/3 cup (120g) (optional, but I never skip them for extra gooeyness)
• For the Filling:
  • Thin Mints cookies – 16 cookies (about one sleeve; use Girl Scout Thin Mints, Keebler Grasshoppers, or any crisp chocolate-mint cookie)
• For Topping (Optional but recommended):
  • Flaky sea salt – a sprinkle before baking (makes the chocolate pop, totally optional but so good!)
  • Extra mini chocolate chips – to press on top for a bakery-style look

Ingredient Tips: I always go with Ghirardelli or Hershey’s Special Dark cocoa powder if I’m feeling fancy, but store-brand works in a pinch. If you’re out of Thin Mints, honestly—Keebler Grasshoppers taste almost identical. For a gluten-free version, swap in your favorite 1:1 gluten-free flour blend and gluten-free mint cookies (I’ve tried Simple Mills and they’re great!). Dairy-free? Use vegan butter and allergy-friendly chocolate chips—no one will notice.

Equipment Needed

• Mixing bowls: One large and one medium. If you bake a lot, glass bowls are great for seeing if everything’s mixed.
• Electric hand mixer or stand mixer: Either works. I’ve made these with just a sturdy spoon and elbow grease, but an electric mixer saves time (and your arm!).
• Baking sheet: Standard half-sheet pans work perfectly. Line with parchment for easy cleanup.
• Parchment paper or silicone baking mat: Prevents sticking and keeps cookies from spreading too much.
• Cookie scoop (about 2 tablespoons): Not required, but it makes portioning neat and fast. I use a medium OXO scoop.
• Measuring cups and spoons: Accurate measurements make a difference with cocoa powder and flour, trust me.
• Cooling rack: If you don’t have one, a clean oven rack on the counter works (I did this for years!).

If you don’t have a cookie scoop, just use a big spoon and your (clean!) hands to shape the dough around the Thin Mint. Silicone mats are worth it if you bake often—they last forever and keep cookies from sticking. As for maintenance, always hand wash your silicone mats and let them air dry; they can get a little greasy if you use the dishwasher. And if you’re on a budget, don’t splurge on a fancy stand mixer unless you bake all the time—hand mixing works just fine for these cookies.

How to Make Thin Mint Stuffed Chocolate Mint Cookies

1. Prepare Ingredients: Take your butter out to soften about 30 minutes before starting. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
2. Mix Dry Ingredients: In a medium bowl, whisk together 1 1/4 cups (150g) flour, 1/2 cup (50g) cocoa powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt. Set aside.
3. Cream Butter & Sugars: In a large bowl, beat 1/2 cup (113g) softened butter with 1/2 cup (100g) brown sugar and 1/4 cup (50g) granulated sugar for 2–3 minutes until light and fluffy. Use medium speed with a mixer, or a sturdy spoon and some muscle.
4. Add Egg & Flavorings: Scrape down the bowl. Add 1 large egg, 1 teaspoon peppermint extract, and 1/2 teaspoon vanilla extract. Beat again until smooth and creamy (about 1 minute).
5. Combine Wet and Dry: On low speed, gradually add the dry ingredients to the wet mixture. Mix until just combined—don’t overmix or your cookies get tough.
6. Add Chocolate Chips: Fold in 2/3 cup (120g) mini chocolate chips with a spatula.
7. Shape Cookies: Scoop about 2 tablespoons of dough (about 40g) and flatten into a disk in your palm. Place a Thin Mint cookie in the center, then wrap the dough around it, sealing well so the Thin Mint is fully covered. If dough’s sticky, chill for 10 minutes or dust your hands with cocoa powder.
8. Place on Baking Sheet: Space cookies 2 inches (5 cm) apart. They spread a little, but not much. Press a few extra mini chips on top for bakery vibes, and sprinkle with flaky sea salt if using.
9. Bake: Bake for 10–12 minutes, until edges are set but centers look slightly soft. (Don’t wait for them to look “done”—they’ll firm up as they cool. Overbaking dries out the fudgy middle!)
10. Cool: Let cookies cool on the baking sheet for 5–7 minutes before transferring to a wire rack. Don’t skip this—if you move them too soon, they might crack or break.
11. Serve: Enjoy slightly warm (the Thin Mint inside will be dreamy and melty), or let cool completely for a crispier contrast.

Prep Notes: If your dough is too sticky, a quick 10-minute chill in the fridge helps. If you accidentally poke through the dough while sealing, just patch with a little extra—imperfections bake out, promise. And if your cookies spread too much, check your oven temp or use a touch more flour next time.

Personal Tip: When I’m baking these for a party, I do all the dough shaping first (assembly-line style), then bake in batches. That way, the cookies are all the same size and I don’t get flustered juggling trays.

Cooking Tips & Techniques

• Don’t Overmix: Once you add the flour, mix just until combined. Overmixing makes the cookies dense instead of fudgy.
• Watch the Bake Time: These cookies should look a little underdone in the middle when you pull them out. They’ll set up as they cool. Overbaking leads to dry, cakey insides (been there, regretted that).
• Seal Well: Make sure the dough fully covers the Thin Mint. Any exposed cookie will leak and get weirdly chewy. Pinch and smooth the dough—imperfections are okay, but big gaps aren’t.
• Chill for Neatness: If your dough is sticky, pop it in the fridge for 10–15 minutes. Especially helpful if your kitchen’s warm (hello, summer bakers!).
• Consistent Size: Use a cookie scoop or weigh the dough balls for even baking. Uneven sizes = some cookies overbaked, some raw. I learned this the hard way during my first holiday bake-a-thon!

Personal Lessons: The first time I made these, I didn’t seal the dough well enough and Thin Mint filling oozed out. Now, I always double-check and pinch the seams closed. I also realized that using Dutch-process cocoa powder makes the cookies extra rich—regular cocoa works, but the flavor isn’t as deep.

Finally, if you’re multitasking (baking while wrangling kids or answering emails), set a timer! These cookies go from perfect to overbaked in a flash. And always let them cool on the tray before moving—trust me, patience pays off here.

Variations & Adaptations

• Gluten-Free: Use a 1:1 gluten-free flour blend and gluten-free mint cookies. Simple Mills or Goodie Girl both make great options. The texture stays soft and fudgy.
• Dairy-Free: Swap unsalted butter for vegan butter, and use dairy-free mini chocolate chips. The cookies still taste amazing and the mint flavor really shines.
• Change Up the Filling: No Thin Mints? Use peppermint patties, Andes mints, or even another favorite chocolate cookie (like Oreos) for a fun twist. I once tried these with caramel-filled chocolates in the center—so rich, but totally worth it.
• Seasonal Flavors: Add a touch of orange zest to the dough for a chocolate-orange-mint vibe, or throw in some chopped dried cranberries for a holiday flair.
• Allergen Adaptation: For nut allergies, just make sure your chocolate chips and cookies are processed in a nut-free facility. Some store brands are actually safer than the big names!

Personal Variation: One winter, I crushed a few extra Thin Mints and rolled the dough balls in the crumbs before baking. The extra crunch and burst of mint—wow. Highly recommend if you want a little extra something!

Serving & Storage Suggestions

Serving: These Thin Mint Stuffed Chocolate Mint Cookies are best served slightly warm—think gooey center and melty Thin Mint. If you want to get fancy, dust with a little powdered sugar or drizzle with melted white chocolate. Pair with cold milk, hot cocoa, or even a scoop of vanilla ice cream for a true dessert moment.

Presentation Tips: Arrange on a pretty plate or tiered stand, and sprinkle with extra mini chocolate chips or crushed Thin Mints for a bakery-style look. They make adorable gifts, too—just pop a few in a box with parchment and a cute ribbon.

Storage: Store leftovers (if you have any!) in an airtight container at room temperature for up to 4 days. For longer storage, refrigerate for up to a week—they actually get fudgier as they sit. To freeze, place cooled cookies in a single layer on a baking sheet, freeze until solid, then transfer to a zip-top bag. They’ll keep for up to 2 months. Reheat in the microwave for 10–15 seconds to revive that gooey magic.

Flavor Tip: The mint flavor gets even better after a day or two, so don’t be afraid to bake ahead!
