Homemade Thin Mints Girl Scout Cookies Recipe

There’s something about homemade Thin Mints that instantly brings back memories of after-school snacks, holiday cookie trays, and late-night freezer raids. I started making these at home one winter when I couldn’t find the real Girl Scout cookies anywhere near me, and honestly, these turned out even more chocolatey and fresh tasting. The crisp chocolate cookie paired with that cool peppermint coating is just hard to beat.

What I really love about this homemade Thin Mints recipe is how simple the ingredients are compared to store-bought versions. Plus, your kitchen smells amazing while these bake — deep cocoa, butter, and mint all together. It feels cozy and nostalgic at the same time.

These cookies are perfect during Christmas season, winter weekends, movie nights, bake sales, or honestly anytime you want a copycat Girl Scout cookies recipe without waiting for cookie season.

Why This Homemade Thin Mints Recipe Is So Good

The biggest difference between homemade and boxed Thin Mints is texture and flavor. Homemade ones have a richer cocoa flavor and a fresher peppermint taste that dosen’t taste artificial. They’re thin, crispy, and have that satisfying snap once the chocolate coating hardens.

Another reason this recipe works so well is because the dough rolls out beautifully after chilling. You get bakery-style cookies without needing fancy equipment.

I also like keeping these in the freezer because they taste incredible ice cold. If you grew up eating frozen Thin Mints straight from the box, you already know what I mean.

Best Time, Mood, and Occasion for These Cookies

These peppermint chocolate cookies are best for:

Winter and holiday season
Christmas cookie exchanges
Cozy weekend baking
Girls’ night dessert trays
Birthday party dessert platters
After-dinner sweet cravings
Freezer snacks during summer too honestly

Mood wise, these are comfort cookies. They feel nostalgic, relaxing, and kinda fancy without actually being difficult.

Approximate Cost

Making a batch of homemade Thin Mints in the United States usually costs around $10 to $14 total depending on the chocolate brand you buy. The recipe makes about 40 small cookies, so it’s actually cheaper than buying multiple Girl Scout boxes.

Ingredients You’ll Need

For the Chocolate Mint Cookies

1 cup unsalted butter, softened
1 cup granulated sugar
1 large egg
1 teaspoon peppermint extract
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour
3/4 cup unsweetened cocoa powder
1/2 teaspoon salt
1/2 teaspoon baking powder

For the Chocolate Coating

2 cups semi-sweet chocolate chips
2 tablespoons coconut oil
1/2 teaspoon peppermint extract

Ingredient Tips

Use regular unsweetened cocoa powder instead of Dutch cocoa if you want that classic Girl Scout flavor. I tested both, and regular cocoa gives a more nostalgic taste.

Peppermint extract can get overpowering really quick. One time I accidentally added extra and the cookies tasted like toothpaste, not even joking. So measure carefully.

For chocolate chips, I usually use Ghirardelli or Guittard because they melt smoother and coat the cookies better.

Equipment Needed

Mixing bowls
Electric hand mixer or stand mixer
Rolling pin
Parchment paper
Baking sheets
Small round cookie cutter
Cooling rack
Microwave-safe bowl

How I Came Across This Recipe

I actually started making homemade Thin Mints during a snowstorm a few years ago. I was craving Girl Scout cookies so bad but couldn’t get out to the store. I searched through old handwritten family recipes and combined ideas from classic chocolate wafer cookies and peppermint bark.

The first batch was honestly terrible — way too thick and soft. But after testing different flour amounts and chilling times, I finally got that crispy thin texture that tastes super close to the original cookies.

Now I make them almost every holiday season because friends always request them.

Step-By-Step Instructions

Step 1: Cream the Butter and Sugar

In a large mixing bowl, beat the softened butter and sugar together for about 2 to 3 minutes until light and fluffy. Don’t rush this part because it helps create a crisp cookie texture later.

Step 2: Add the Wet Ingredients

Mix in the egg, peppermint extract, and vanilla extract. The dough might look slightly separated at first but keep mixing and it’ll smooth out.

Step 3: Combine the Dry Ingredients

In another bowl, whisk together the flour, cocoa powder, salt, and baking powder.

I always sift cocoa powder because lumps can happen easy and nobody wants dry cocoa pockets in cookies.

Step 4: Make the Dough

Slowly add the dry ingredients into the wet mixture. Stir until a thick chocolate dough forms.

The dough should feel soft but not sticky. If it’s too sticky, chill it for 10 minutes before rolling.

Step 5: Chill the Dough

Wrap the dough in plastic wrap and refrigerate for at least 1 hour.

This step matters alot because cold dough rolls thinner and bakes crispier.

Step 6: Roll the Dough Thin

Preheat your oven to 350°F.

Place dough between two sheets of parchment paper and roll it very thin — around 1/8 inch thick. Thin dough is the secret to authentic copycat Thin Mint cookies.

Step 7: Cut the Cookies

Use a small round cookie cutter, about 2 inches wide, to cut circles.

Place them on parchment-lined baking sheets about 1 inch apart.

Step 8: Bake Until Crisp

Bake for 9 to 11 minutes.

The cookies may seem slightly soft at first, but they crisp up as they cool. Don’t overbake or they can become bitter tasting.

Step 9: Cool Completely

Transfer cookies to a cooling rack and let them cool fully before dipping into chocolate.

Warm cookies will make the coating messy.

Step 10: Prepare the Chocolate Coating

In a microwave-safe bowl, melt chocolate chips and coconut oil in 30-second intervals, stirring each time.

Once smooth, stir in peppermint extract.

The smell at this point is honestly incredible.

Step 11: Dip the Cookies

Using a fork or dipping tool, coat each cookie completely in melted chocolate.

Tap off excess chocolate gently and place cookies back onto parchment paper.

Step 12: Let the Chocolate Set

Allow cookies to sit at room temperature or refrigerate for faster setting.

I personally like putting them in the freezer because frozen Thin Mints taste amazing.

Homemade Baker’s Tips

Roll dough evenly so cookies bake uniformly

Storage Tips

Store these cookies in an airtight container for up to:

Frozen is honestly the best way to eat them.
