Let’s be real—Thin Mints are addictive, and waiting for Girl Scout season to roll around just doesn’t cut it. I used to ration the boxes I bought, but once I figured out this homemade version, problem solved.
These have that same crisp texture and cool peppermint hit, but you get to skip the preservatives and waxy chocolate.
And yeah, they’re actually better. You control everything—from sweetness to chocolate depth—and the end result feels like an upgrade, not just a copy.
What Makes These Homemade Thin Mints Legit
Let’s get this straight—this isn’t some shortcut recipe with Ritz crackers and melted Andes mints. These are baked from scratch with actual cocoa, peppermint extract, and a dark chocolate shell. The final texture? Crisp and clean, just like the originals. Maybe even better.

Here’s where it goes beyond just a Girl Scout cookie copycat:
- Custom flavor control: You decide how strong the peppermint hits or how dark the chocolate goes.
- Higher quality ingredients: Real butter, premium cocoa, and legit chocolate = no waxy finish or weird aftertaste.
- Adaptable for special diets: You can make it gluten-free, vegan, or low-sugar without killing the texture.
Most so-called “homemade Thin Mint recipes” online don’t go this deep. They cut corners or skip the texture altogether. This version respects the original while letting you take it further.
Key Ingredients That Actually Matter
Don’t let the short list fool you. Quality here isn’t optional—it’s everything. A few things I’ve learned from trial and error:
- Cocoa powder: Dutch-processed gives a smoother, less acidic flavor. Natural cocoa makes them taste flat and muddy.
- Peppermint extract: Skip the imitation stuff. It tastes like chemicals. Use pure extract, preferably alcohol-based for best distribution.
- Dark chocolate: At least 60% cacao, ideally couverture chocolate like Callebaut or Valrhona. Anything too sweet ruins the balance.
- Flour: Standard all-purpose works fine, but for gluten-free, a 1-to-1 baking blend holds structure best.
And please—for the love of cookies—don’t use chocolate chips for coating. They don’t melt right and leave a dull, uneven shell.
Tips for Getting That Classic Snap
This isn’t a complicated recipe, but it rewards attention to detail. A few mistakes I’ve made (and fixed):
- Roll dough thin: Aim for about 1/8 inch. Too thick and they lose that signature crunch.
- Freeze the cut-out dough before baking: It helps them hold shape and bake evenly.
- Tempering chocolate? Worth it: It’s optional, but if you’re gifting or storing at room temp, tempered chocolate keeps the shell snappy and streak-free.
- Use a fork for dipping, not your fingers: Less mess, better coating.
If you’re not into tempering, that’s fine—just store the cookies in the fridge or freezer to keep the chocolate crisp.
Easy Modifications for Every Diet
You don’t have to follow the classic version to the letter. This recipe holds up well with smart ingredient swaps. Here’s what’s worked for me:
- Gluten-free Thin Mints: Use a GF baking blend that includes xanthan gum. Don’t try to sub almond flour on its own—it won’t crisp up right.
- Vegan Thin Mints: Swap butter for a plant-based baking stick (like Miyoko’s) and use dairy-free dark chocolate (Look for cocoa butter-based brands).
- Low sugar version: Use sugar-free dark chocolate and reduce the sugar in the dough slightly to compensate. Look for brands that use monk fruit or erythritol.
These modifications keep the cookie close to the original—same crunch, same snap, same cool mint finish.
Storing & Serving: Long Shelf Life, Big Payoff
Another underrated win? These cookies keep really well. You can stash them away and eat them cold, which honestly makes the flavor better.
Here’s how to store:
- Room temperature: Airtight container, 5–7 days max. Good for gifting.
- Refrigerator: Keeps them fresher, up to a month. Texture stays crisp.
- Freezer: This is the move. Store for 4–6 months and eat straight from the freezer. That cool mint hit is next-level.
For serving, they go great with black coffee, peppermint tea, or even crumbled into a chocolate mousse. I’ve also used them as an ice cream topping and layered into frozen dessert bars.
This Isn’t Just Nostalgia—It’s a Better Recipe
Here’s the thing about baking homemade Thin Mints: it’s not just about cloning a childhood memory. It’s about making a crisp chocolate mint cookie that tastes like the real deal but feels even more rewarding.
You get clean ingredients, a better chocolate-mint balance, and the flexibility to tweak it however you want. It’s a go-to recipe for dessert lovers who want something familiar, but fresher.
Honestly, I don’t even buy the boxed ones anymore. Once you get used to the real cocoa and real chocolate coating, the commercial versions feel like a downgrade.
Homemade Thin Mints Recipe
Equipment
- 2-inch fluted round cutter
- Offset spatula
- Wax paper
Ingredients
- 1 recipe Mint Chocolate Wafer Dough
- ⅓ cup Dutch-process cocoa powder for dusting
- 4 cups finely chopped dark chocolate 55% cocoa
Instructions
Make the cookies:
- Preheat the oven to 375°F and position a rack in the center. Dust a work surface lightly with cocoa powder.
- Roll the dough into a 6-inch square. Dust both sides of the dough with cocoa powder, then roll until it’s ¼ inch thick.
- Using a 2-inch fluted round cutter, cut out cookies and arrange them on a parchment-lined baking sheet with ¼ inch spacing. Gather dough scraps, knead briefly, and re-roll to cut more cookies.
- Bake the cookies until firm and dry, about 20 minutes. Let them cool completely on the baking sheet.
- Use immediately, store in an airtight container for up to 2 weeks at room temperature, or freeze for up to 2 months.
Dip the cookies:
- Set up a dipping station with cooled cookies on one side, tempered chocolate in the middle, and two parchment-lined sheets on the other side.
- Temper the chocolate (refer to the source for details), and dip each cookie into it, using a fork to lift and let excess chocolate drip off.
- Place each coated cookie on a prepared sheet. Optionally, run a fork across the chocolate for a wavy design.
- Refrigerate the cookies for 15 minutes to harden the chocolate.
Store the cookies:
- Transfer the cookies to an airtight container, placing wax paper between layers.
- Store at room temperature for up to 1 week, in the refrigerator for up to 1 month, or in the freezer for up to 6 months.
Notes
- Cookies dipped in untempered chocolate must be stored and served cold.
- You can skip tempering the chocolate if you prefer to eat these cookies straight from the freezer.
- Opt for chocolates like Valrhona’s 55% Equatoriale or Callebaut’s 54.6% Couverture for the best flavor balance.
