The image shows six white bowls and plates arranged on a white marbled surface. The largest bowl at the top contains light brown flour with a soft, powdery texture. Below it to the left, a smaller bowl holds white powdered sugar, looking fluffy. To the right, another small bowl is filled with dark brown cocoa powder with a fine texture. Below these, there is a tiny bowl with a small amount of off-white liquid, likely vanilla or milk, smooth and shiny. Next to it, there is a bowl with clear, thick liquid, possibly oil. Finally, a white plate at the bottom right holds several small blocks of pale yellow butter, soft and slightly shiny on the edges. The arrangement is neat and the colors range from white to brown and yellow tones, all on a clean white marbled background. Photo taken with an iphone --ar 4:5 --v 7

Getting these cookies just right depends on a handful of straightforward but perfectly complementary ingredients. Each one plays a crucial role—from the cocoa powder that gives the cookies their deep chocolate color and flavor, to the peppermint extract that makes the filling so refreshing and addictive.

All-purpose plain flour (2 cups / 250g): The base of your cookies, providing structure and that perfect, tender crumb.
Vegan butter (1 cup / 225g for cookies + ½ cup / 125g for filling): Adds richness and moisture for that melt-in-your-mouth texture.
Powdered sugar / icing sugar (1 ¼ cups / 125g for cookies + 2 cups / 200g for filling): Delivers sweetness and ensures the cookies stay soft while the filling is luxuriously smooth.
Dutch-process cocoa powder (½ cup / 50g): Gives a deep chocolate flavor and a gorgeous dark color without any bitterness.
Baking soda (¼ teaspoon): Helps the cookies rise gently and spread just right for that perfect crunch.
Dairy-free milk (about 3 tablespoons / 45g for cookies and 2 tablespoons / 30g for filling): Keeps the dough moist and the buttercream silky without any dairy.
Peppermint extract or oil (few drops): The magical ingredient that transforms these into minty delights!
Vanilla extract (1 teaspoon, optional): Adds warmth and balances the mint flavor beautifully.
Green food coloring (a few drops): For that signature minty color that makes these cookie sandwiches so visually inviting.

How to Make Vegan Mint Chocolate Cookies Sandwiches Recipe

Step 1: Prepare the Chocolate Cookie Dough

Begin by combining all cookie ingredients except for the milk in a food processor or a large mixing bowl. This is where the magic starts—bringing together the flour, cocoa powder, vegan butter, powdered sugar, and baking soda creates a rich dough base. Gradually add the dairy-free milk, just one tablespoon at a time, mixing until the dough comes together and is pliable without crumbling when pinched. This step sets the foundation for cookies that’ll hold their shape beautifully while baking.

Step 2: Roll and Cut the Cookies

Preheat your oven to 180°C (350°F) and line baking sheets with parchment paper for easy clean-up. Lightly flour your surface or lay out parchment to roll the dough evenly to about ¼ inch (6 mm) thickness. Use a 2-inch (6 cm) round or fluted cookie cutter to cut out your cookie shapes. Gather the scraps, reroll, and repeat until you’ve used all the dough. The precision here is a joy—you’ll love the feeling of cutting charming circles that will become crunchy, chocolaty discs.

Step 3: Bake to Perfection

Arrange the cookies on your sheets with about an inch (2 cm) space around them, as these cookies don’t spread much during baking. For softer cookies, bake for 10-12 minutes; if you prefer them extra crunchy, give them up to 15 minutes. After removing from the oven, allow the cookies to cool completely on the trays. This patience pays off because cooling helps them crisp up just right and makes them easier to handle when sandwiching.

Step 4: Whip Up the Peppermint Cream Filling

In a medium bowl, beat the vegan butter on its own until it’s light and fluffy—this ensures your buttercream will be airy and smooth. Gradually add the powdered sugar, beating on low first to avoid a sugar cloud, then on high until fluffy and well combined. Add a few drops of peppermint extract and vanilla if using, plus green food coloring to your preferred shade. If the buttercream is too thick, slowly mix in dairy-free milk one tablespoon at a time until spreadable. Taste and adjust—the filling is what truly gives these cookies their signature refreshing flair.

Step 5: Assemble Your Cookie Sandwiches

Finally, take half of your cooled cookies and pipe or spread a generous dollop of the peppermint buttercream onto the bottom of each. Top with the remaining cookies to form sandwiches. Press gently so the filling spreads evenly to the edges. The satisfying look and taste of these cookie sandwiches are worth every bit of effort—each one a mini masterpiece of texture and flavor.

Garnishes

To elevate presentation and add a little crunch, sprinkle finely chopped dark vegan chocolate or crushed peppermint candies on the edges of the filling after assembling. A light dusting of powdered sugar over the top adds a pretty snow-like finish, perfect for cozy gatherings or holiday treats.

Side Dishes

Serve your vegan mint chocolate cookies sandwiches alongside a cold glass of almond milk or a mug of hot peppermint tea to echo the mint notes and balance the sweetness. For a grown-up twist, pair them with a rich vegan hot chocolate to immerse yourself in ultimate comfort.

Creative Ways to Present

Stack the sandwiches in a clear glass jar or arrange them neatly on a rustic wooden platter for an irresistible display. Tie each cookie sandwich gently with a festive ribbon if gifting, or create a beautiful dessert platter by alternating these cookies with fresh mint leaves and berries for a pop of color.

Make Ahead and Storage

Storing Leftovers

You can store these cookie sandwiches in an airtight container at room temperature for 1-2 days without losing their delightful texture. If you plan to keep them longer, refrigerate for up to a week to maintain freshness and prevent the buttery filling from becoming too soft in warmer conditions.

Freezing

To freeze, place the cookie sandwiches in a single layer on a tray and freeze until firm. Once frozen, stack them with parchment paper between layers in a freezer-safe container or ziplock bag for up to one month. This method preserves both the crunch of the cookies and the lovely peppermint cream inside.

Reheating

Bring frozen cookie sandwiches to room temperature before enjoying. If you want to refresh the crunch, pop them in a preheated oven at 150°C (300°F) for 3-5 minutes. Be cautious not to melt the filling; aim for a gentle warming to revive their original texture and taste.

FAQs

Can I use regular butter instead of vegan butter?

Absolutely! If you’re not strictly vegan, regular butter will work fine in this recipe, though keep in mind the result won’t be dairy-free. The taste and texture will still be deliciously rich and creamy.

What if I don’t have peppermint extract? Can I substitute it?

If peppermint extract isn’t on hand, you could try using a few drops of spearmint extract or even a tiny pinch of finely chopped fresh mint leaves, but peppermint extract provides that classic crisp flavor best suited for these cookies.

How can I make these gluten-free?

To make this Vegan Mint Chocolate Cookies Sandwiches Recipe gluten-free, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Make sure the blend contains xanthan gum or add it separately to maintain structure.

Can I make the cookie dough ahead of time?

Yes! You can prepare the dough up to 24 hours in advance and refrigerate it wrapped tightly in plastic wrap. This resting time actually helps deepen the flavors and can improve the texture of the cookies.

What causes the cookies to be crumbly and how can I fix it?

If your dough feels too dry or crumbly, it means it needs a bit more moisture. Slowly add dairy-free milk one teaspoon at a time while mixing, until it comes together smoothly and holds when pinched between your fingers.
