Copycat Gluten-Free Thin Mints (2024)

I become a jealous green monster when Girl Scout season begins. That’s because I love Thin Mint cookies, but they contain gluten. I figured out how to make my own copycat gluten-free Thin Mint cookies and share the recipe in this post. Please note Thin Mints is a registered trademark of the Girl Scouts of America.

I used to stock up on Thin Mint cookies once Girl Scout cookie season arrived. Thin Mints are and always will be my favorite flavor cookie.

Of course, since you’re seeing this recipe on the Good For You Gluten Free website, you know I can’t eat gluten, a protein found in wheat, rye, barley, and sometimes oats. This means you know I can no longer eat Thin Mints.

In recent years, the Girl Scouts have included the gluten-free community by launching two gluten-free cookies, Caramel Chocolate Chip and Toffee-tastic cookies. While I feel the Girl Scouts made a nice gesture by including their gluten-challenged members and cookie-buying friends, I find both cookies taste only fair.

Maybe I’m stubborn and resistant to change, but I really want a Thin Mint cookie. And like every other food I dearly miss, I must figure out how to make it myself if I want it.

How to Make Gluten-Free Thin Mints

One of my favorite non-GF blogs, Sally’s Baking Addiction, has a wonderful Thin Mint Cookie recipe. Her Thin Mint recipe isn’t gluten-free, but I changed it to make it gluten-free and still delicious. Here’s how to make gluten-free Thin Mint Cookies:

Step #1: Gather Your Ingredients

For the cookie dough, you’ll need the following:

• 3/4cupunsalted butter,room temperature
• 1cupgranulated sugar
• 1large egg,room temperature
• 1tspvanilla extract
• 1/4tsppeppermint extract
• 200gramsBob’s Red Mill 1-to-1 Gluten-Free Flour Blend, approximately 1 1/2 cups, spooned and leveled
• 3/4cupunsweetened cocoa powder
• 1tspbaking powder
• 1/8tspsaltpinch

For the chocolate coating, you’ll need the following:

• 2cupssemi-sweet chocolate chips
• 1tspavocado oilor other vegetable oil
• 1/4tsppeppermint extract

Step #2: Make the Cookies

Now you’re ready to make the round cookie that will become the center of your Thin Mint.

Start by beating the butter for one minute in a large bowl using your handheld or standing mixer until it’s smooth and creamy. Add the sugar and continue mixing on medium-high speed, then add the egg, vanilla extract, and peppermint extract and mix until well combined.Set aside.

Sift the flour, cocoa powder, baking powder, and salt in a separate bowl. Then add the dry ingredients slowly to the wet ingredients and mix on low speed until the flour is fully incorporated. The dough will come together when handled, but it will look crumbly in the bowl.

Divide the dough into two equal-sized balls so you can work the dough in batches.

Use your rolling pin to flatten each ball between two pieces of plastic wrap or parchment paper until about 1/4″ thickness. Put the rolled-out flat dough in your refrigerator to chill for 1 hour or up to two days. Make sure it’s covered with plastic wrap if you’re chilling longer than 1 hour.

Once chilled, preheat your oven to 350º F and line two large baking sheets with parchment paper.

Using a 1-1.5″ round cookie cutter, cut out cookies into small circles and place each cookie on the lined baking sheets about 1″ apart. Re-roll the remaining dough. You should have about 40+ cookies, depending on the circles’ size and the dough’s thickness.

Bake the cookies for 8 minutes. If the cookies are on two baking sheets, place one baking sheet in the fridge to keep cool before baking. Do not overbake. The dough should still be a bit soft to the touch.

Keep in mind that depending on the thickness of the cookie, they may spread/expand a bit, but generally, they keep their shape and size just fine.

Allow the baked cookies to cool for 5 minutes on the baking sheet before transferring them to a wire rack to cool completely.

Step #3: Coat Each Cookie with Chocolate

Now it’s time for the fun part: covering the cookies with a delicious, shiny chocolate coating.

Start by melting the chocolate and vegetable oil in a large microwave-safe bowl, mixing the chocolate every 15-30 seconds until melted. Add some peppermint extract after the chocolate has melted, and mix well. Remember, a little peppermint extract goes a long way.

Now, coat each cookie with melted chocolate. Use a fork to scoop up the cookie from the melted chocolate, bang off the excess chocolate, and remove any air bubbles from the top of the coating.

Place each coated cookie on a parchment-lined baking sheet to cool and set. Coat each cookie individually until all cookies are covered in chocolate.

Step #4: Wait for the Chocolate to Set

Allow the shiny chocolate to set on the cookies before enjoying them. The chocolate will harden and darken, even at room temperature, but if you’re anxious to eat the cookies sooner, place them in your fridge for 15 minutes.

I don’t have much fridge space to spare, so I leave mine out until the chocolate sets, then I put them in a zip-top bag to store in my freezer. You can store the cookies in your fridge or freezer, but I recommend the freezer for maximum, prolonged enjoyment.

How Do They Taste?

Dare I say these gluten-free Thin Mint cookies taste better than Girl Scout Thin Mints? I don’t know if that’s blasphemy, but these are seriously good cookies, and you’ll be in heaven now that you’ve baked this beloved cookie from scratch at home.

The cookies are slightly crunchy and even have a bit of a chewy texture, which I like and prefer. The chocolate coating is generous, and the peppermint flavor is present in every bite!

FAQs

Here are answers to some of your most pressing questions:

Can I make the cookies dairy-free? Yes, use dairy-free butter and dairy-free chocolate chips.

Can I make this recipe egg-free? I haven’t tried it, but I imagine it would work. Use a flax egg (1 tbsp flax mixed with 3 tbsp water). Let me know if it works for you (results may vary).

How do I store the cookies? Store the cookies in your fridge or freezer. The chocolate may melt a bit or soften if left on the counter.

Help, my cookies spread! If your cookies spread during baking, you may not have fully chilled the dough. Chilled dough will not spread.

I don’t have 1-1.5″ cookie cutters. I suggest investing in cutters or cutting out cookie shapes using the rim of a glass. You could also cut them into small hearts for Valentine’s Day or another shape of your choice. The chocolate adds bulk to each cookie. They may look small after bake, but they look giant after they’re coated with chocolate.

Which Girl Scout Cookies are gluten-free? Caramel Chocolate Chip or Toffee-tastic. Read my review of each cookie in this article.
