Vegan Thin Mint Cookie Recipe: Minty Chocolate Crunch Without Dairy

This vegan Thin Mint cookie recipe delivers all the classic Girl Scout flavors—cool minty frosting, chocolate crunch, and buttery texture—without any dairy or eggs. 💚 The secret lies in using refined coconut oil for that signature melt-in-your-mouth richness while keeping the cookies crisp at the edges.

I've tested this recipe dozens of times to perfect the balance between tender centers and crispy edges, even with plant-based ingredients.

The magic starts with a simple dough made from flour, coconut oil, and a touch of vanilla, then chilled to ensure clean cuts and proper texture.

After baking, the cookies get a generous layer of vegan mint frosting that stays vibrant and fresh-tasting, plus crushed vegan chocolate bars for that essential crunch.

What makes this version work is the careful ratio of coconut oil to flour—too much oil makes them spread too thin, while too little risks dryness.

By the time you're done, you'll have cookies that look and taste just like the originals—cool mint frosting that melts slightly on your tongue, chocolate bits that add satisfying texture, and a tender yet sturdy cookie base.

The best part? These keep well in an airtight container for up to a week, making them perfect for baking ahead or sharing with friends who might not realize they're dairy-free.

Whether you're making these for a vegan gathering, a mint chocolate lover, or just craving a nostalgic treat, this recipe delivers professional-quality results with simple pantry ingredients. The frosting stays bright and flavorful (no artificial aftertaste here), and the chocolate maintains its signature snap. Let's get baking!

Ingredients for vegan thin mint cookie

These plant-based ingredients create Thin Mints that rival the originals—crisp edges, tender centers, and vibrant mint frosting!

The coconut oil is non-negotiable here. Refined gives that signature buttery texture without dairy, while unrefined can add coconut flavor. Trader Joe's and Whole Foods carry reliable brands like Nutiva or Cream of Nature. For the chocolate, Enjoy Life or Pascha bars melt beautifully and stay dairy-free. The peppermint extract matters—McCormick or Frontier are my go-to brands, and they're worth the splurge for that authentic mint kick. If you can't find pure extract, peppermint essential oil works at half the amount, but use sparingly.

No refined coconut oil? Vegan butter or olive oil can substitute, but texture will differ slightly—expect softer cookies. Short on mint flavor? Add a pinch of crushed candy canes to the dough for extra zing. For the frosting, vegan cream cheese (like Kite Hill) can replace half the butter for a tangier taste. The chocolate bars? Any dairy-free brand works, but avoid those with palm oil if you're avoiding processed ingredients. Pro tip: crush the chocolate coarsely for texture—a rolling pin works great.

Store the dough in the fridge for up to 3 days or freeze for 3 months—perfect for baking ahead. The frosting keeps for 5 days in an airtight container, but the cookies? Best within 3 days for maximum crispness. To revive stale cookies, pop them in the oven at 300°F for 3-5 minutes. These freeze beautifully too—just wrap individually in parchment and store in a ziplock bag for up to 2 weeks. The mint frosting stays brightest when refrigerated, so assemble cookies the day you plan to serve them.

Step-by-step instructions for vegan thin mint cookies

Here's how to make these minty, chocolatey cookies that taste just like the classic—but totally plant-based!

In a large mixing bowl, combine the 2.5 cups All-Purpose Flour and 0.5 tsp Salt. Whisk together lightly to remove any lumps. In a separate bowl, cream the 1 cup Refined Coconut Oil (at room temperature) with the 0.5 cup Granulated Sugar until smooth and fluffy—about 2-3 minutes using a hand mixer.

Add the 1 tbsp Pure Vanilla Extract, 0.5 tbsp Pure Peppermint Extract, and 1 tsp Mint Extract to the wet ingredients. Mix until fully incorporated—you'll smell that fresh minty aroma! Gradually add the dry ingredients to the wet, mixing on low speed until just combined. Overmixing develops gluten, so stop as soon as the dough comes together.

For extra flavor depth, fold in the 0.5 tbsp Pure Vanilla Bean Paste with a spatula. Then, chop the 8 oz Vegan Chocolate Bars into small chunks and gently fold them into the dough. The chocolate should be evenly distributed but still visible—this creates those classic Thin Mint pockets of chocolate!

Divide the dough into two equal portions and flatten each into a ½-inch thick disc. Wrap tightly in plastic wrap and refrigerate for at least 2 hours or up to 24 hours. Chilling is crucial—it firms up the coconut oil so the cookies hold their shape and don't spread too much in the oven.

Here's the thing—if you skip this step, your cookies might turn out flat and greasy. The cold dough also allows the mint flavor to meld more deeply, giving you that authentic Thin Mint taste. While it chills, preheat your oven to 350°F and line two baking sheets with parchment paper.

Remove one disc of dough from the refrigerator and let it sit at room temperature for 10 minutes while you prepare the baking sheet. Roll the dough between two sheets of parchment paper to about ¼-inch thickness. Use a round cutter (about 2.5 inches in diameter) to cut out cookies, gently re-rolling the scraps as needed.

Place the cut-out cookies 2 inches apart on the prepared baking sheet. Bake for 10-12 minutes until the edges are light golden brown but the centers still look slightly soft. They'll firm up as they cool. Remove from the oven and let them cool on the baking sheet for 5 minutes before transferring to a wire rack.

While the cookies cool, make the frosting by beating the 0.5 cup Vegan Butter and 2 cups Powdered Sugar together until light and fluffy—about 3-4 minutes. Add the 1 tbsp Almond Milk and the 1 tsp Mint Extract (plus a touch more if you want it extra minty), mixing until smooth and spreadable.

Here's where it gets fun—taste the frosting and adjust the mint flavor if needed. You want it to be bright and refreshing, not overpowering. The frosting should be thick enough to hold its shape on the cookies but still spreadable with a spatula.

Once the cookies are completely cool, spread a generous layer of frosting on the flat side of each cookie. I like to use about 1 tablespoon per cookie—enough to cover completely but not so much it drips off. Press a few extra chocolate chunks on top for that classic Thin Mint look.

Let the frosting set for 10 minutes before serving. These cookies are best enjoyed fresh out of the oven when the chocolate is still melty and the mint flavor is at its peak. Store any leftovers in an airtight container for up to 5 days, though I doubt they'll last that long!

Best sauces and condiments for this dish

Classic Mint Frosting

This vegan frosting is the star of your Thin Mints—bright, creamy, and packed with that signature mint flavor. The key is using powdered sugar (not confectioners') and vegan butter for stability, while almond milk adds just enough moisture to keep it spreadable.

For extra vibrancy, I like to add ½ tsp lemon zest to the frosting—it enhances the mint and prevents that "artificial" aftertaste. 💚

Chocolate Variations

Swap out the vegan chocolate bars for dark chocolate (70% cocoa) if you prefer a richer, less sweet crunch. For a white chocolate twist, use Pascha White Chocolate Bars—they melt beautifully and add a creamy contrast.

Pro tip: Pulse the chocolate in a food processor for 3-4 seconds before folding into the dough to create uniform chunks. Avoid over-processing or it'll turn into a paste!

Tangy Cream Cheese Twist

Replace half the vegan butter in the frosting with Kite Hill Almond Milk Cream Cheese for a tangier, more complex flavor. This adds a subtle sharpness that balances the sweetness beautifully.

For extra richness, whisk in 1 tbsp coconut cream—it gives the frosting that luscious, spreadable texture without making it too heavy. 🥛

Spiced Frosting Option

For a warm-spiced variation, add ¼ tsp ground cinnamon and a pinch of nutmeg to the frosting. These spices complement the mint without overpowering it, creating a cozy fall-friendly flavor.

I also like to sprinkle crushed pistachios on top for texture and a pop of color. Store-bought pistachios work, but toasted and skinned ones taste even fresher!

Drizzled Chocolate Glaze

For a restaurant-worthy finish, make a quick vegan chocolate glaze by melting 4 oz vegan dark chocolate with 1 tbsp coconut oil and 1 tsp almond milk. Drizzle this over the frosted cookies right before serving—it adds a glossy sheen and extra chocolatey richness.

Let it set for 5 minutes before serving to prevent drips. This works especially well with the white chocolate variation!

Citrus Zest Boost

Brighten the frosting further with 1 tsp orange zest—it cuts through the sweetness and adds a refreshing citrus note. Pair this with orange extract (¼ tsp) for a zesty twist that still keeps the minty profile.

For a tropical vibe, swap the mint extract for ½ tsp lime zest + ¼ tsp lime extract in the dough. The citrus pairs surprisingly well with the chocolate and coconut oil base. 🍊
